Region: Baja California, Mexico (Pacific Ocean, approximately 150 miles west of the Baja Peninsula)
Type: Volcanic island; great white shark cage diving, pelagic encounters
Significance: The world’s premier destination for underwater photography of great white sharks (Carcharodon carcharias), offering exceptional water clarity (often 100+ feet visibility) and reliable shark encounters during the August-November season
First Wetpixel coverage: 2004

Overview

Isla Guadalupe (Guadalupe Island) is a remote volcanic island in the Pacific Ocean off Baja California, Mexico. Since the early 2000s, it has become the definitive destination for underwater photographers seeking great white shark imagery. The island’s combination of crystal-clear blue water, reliable shark aggregations, and well-organized liveaboard operations has made it a recurring topic across the Wetpixel community, appearing in dozens of forum threads and articles spanning two decades.

As Eric Cheng observed after his November 2004 trip, Guadalupe had rapidly become saturated with quality white shark photography: “The only reason to go to Guadalupe now is for the experience, and for the rare chance that a shark might gnaw on the cage while you are in it with a full-frame fisheye. Most other white shark shots in clear water have now been done” (^[1] — forum). Despite this early assessment, underwater photographers continued to return year after year, drawn by the quality of encounters and improvements in both camera technology and cage design.

Eric Cheng described Guadalupe as “rapidly becoming regarded as the world’s best great white shark destination,” noting water temperatures averaging 65-70F and visibility often exceeding 100 feet. On both of his early trips (September 2003 and November 2004), white sharks appeared around the boat within 30 minutes of arriving, with a dozen or more individuals seen during five days of diving (^[2]).

The island is a major aggregation site for great white sharks, with individual animals identifiable by their markings and scars. Notable identified sharks include “Cal Ripfin” (also known as “Shredder”), distinguished by his ripped dorsal fin, who became one of Guadalupe’s most recognized individuals and the subject of a stylized video titled “Battle Scars” by Joe Romeiro of 333 Productions (^[3]). Other famous sharks include “Deep Blue” and “Lucy,” large females that arrive later in the season (^[4] — forum). The Marine Conservation Science Institute maintained a photo ID database of Guadalupe’s white sharks and offered a sponsor-a-shark program to fund migration research (^[5]).

Conservation and Protected Status

In May 2005, the waters surrounding Isla Guadalupe were granted bio-preserve status by the Mexican government, extending protections that had previously applied only to the island’s land surface. Paul “Doc” Anes of San Diego Shark Diving reported the development, noting that a fee system similar to that of the Revillagigedo Islands (Socorro) might be imposed on operators (^[6]).

In 2007, Mexico passed a shark finning ban that increased protection for great whites, whale sharks, basking sharks, and manta rays. Mike Lever of the M/V Nautilus Explorer responded: “The enactment of Mexican rules for responsible shark and ray fisheries is incredibly good news and really bodes well for the survival of these magnificent animals” (^[7]). Cage diving operators at Guadalupe actively supported conservation through organizations such as the Guadalupe Island Conservation Fund, which was supported by Shark Diver, the vessel operators (Nautilus Explorer, Islander, Horizon, Ocean Odyssey), and DivingWithSharks.com, alongside the Mexican research program led by biologist Mauricio Hoyos Padilla (^[8]).

A code of conduct for great white shark diving was put in place by Mexico’s National Commission of Natural Protected Areas (CONANP) to regulate all activities at the site (^[9]).

In 2016, marine biologists used an underwater autonomous vehicle equipped with cameras to observe and film great white shark predatory behavior at Guadalupe for the first time. The findings, published in the Journal of Fish Biology, showed that the underwater drone was attacked nine times by four different sharks in thirteen hours of footage, providing new insights into hunting strategy (^[10]).

Cage Diving Operations

All diving at Guadalupe takes place from liveaboard vessels departing from San Diego or Ensenada, with the crossing typically taking 18-24 hours each way. Departing from Ensenada shaves many hours off the transit time compared to San Diego (^[11]). The main season runs from August through November, with the largest female sharks arriving in October and November (^[12] — forum).

Liveaboard Operators

Several liveaboard operators have served the Guadalupe white shark diving market, discussed extensively on Wetpixel:

• Solmar V — A 112-foot luxury vessel that comfortably held 22 divers (typically capped at 16 for photography trips), the Solmar V was one of the longest-running operators (^[13]). It maintained a special chumming permit under a grandfather clause, having kept up with required environmental impact studies each year. Other boats were not permitted to chum after regulations tightened (^[14] — forum). The vessel was represented by Jose Luis Sanchez and Leslie Lee and operated as part of the Pelagic Fleet, running four-season itineraries to Socorro, the Sea of Cortez, and Guadalupe (^[15]). Solmar V also served as sponsor for Wetpixel’s Picture of the Week competition, offering trips as prizes (^[16]).

• Nautilus Explorer / Nautilus Belle Amie — Popular among Wetpixel members, the Nautilus fleet offered both surface and submersible cages. The Nautilus Explorer featured four cages: two 4-person surface cages and two submersible cages (one 2-person, one 4-person) that dropped to approximately 40 feet. Rotations through the submersibles gave each diver about three 45-minute sessions per day (^[17] — forum). The submersibles used hookah air supply and ballast systems controlled by a divemaster (^[18] — forum). Some operators on the Nautilus Explorer also allowed experienced divers to climb on top of suspended cages when conditions permitted (^[19] — forum). The Nautilus offered satellite internet for a small fee, an important consideration given the island’s extreme remoteness (^[20] — forum). In 2006, the Nautilus Explorer also hosted the “HD Odyssey” expedition with Light & Motion’s Connor Kirsch and Backscatter’s Sy Harris, offering HD video seminars and air transportation from San Diego to Guadalupe (^[21]).

• M/V Horizon — Based out of San Diego, operated by Horizon Charters. Ran trips with both surface and submersible cages (^[22] — forum). Horizon Charters was also the company that announced the 2021-2022 Guadalupe closures and led appeals against the decision (^[23]).

• M/V Islander — Based out of San Diego, known for a strong safety record and concern for shark welfare. The Islander featured two 4-person surface cages with alternating hourly rotations and a single-diver submersible cage to 40 feet with a divemaster (Jimi Partington, featured in multiple Shark Week shows). There was no loud music or aggressive bait wrangling toward the cages. Marine biologist Mauricio Hoyos Padilla from the Mexican government would visit the boats to give lectures on great white ecology and behavior (^[24] — forum). The Islander was also capable of conducting out-of-cage dives for experts and National Geographic productions (^[25] — forum).

• Great White Adventures / Shark Diving International — Based in Alameda, California (875A Island Drive #338), operated the vessel Searcher and offered surface and deep cages. Lawrence Groth represented the company at DEMA 2006, presenting shark trips to Guadalupe, Fiji, and South Africa (^[26]; ^[27] — forum).

• San Diego Shark Diving Expeditions / Shark Diver — Early operators offering dedicated imaging trips with workshop components. CEO Patric Douglas was an outspoken advocate for shark conservation and shark tourism (^[28]; ^[29]).

• Southern Sport — Used by groups of photographers including Alex Suh, who described it as “the boat from which I usually do my great white diving at Isla Guadalupe” (^[30]).

Cage Design and Evolution

Cage design at Guadalupe evolved significantly over the years, driven by both photographic needs and safety concerns. Surface cages were hung from the stern of the vessel at a depth of approximately 8-10 feet, while submersible cages used hookah air supply and ballast systems controlled by a divemaster to descend to approximately 20-40 feet (^[31] — forum).

The 2006 Wetpixel expedition introduced a special 2-person “cinema cage” with two large 4-foot by 8-foot windows, lowered to 20 feet below the surface, in place of the standard 1-man submersible cage (^[32]).

After two well-publicized cage breach incidents in late 2016, operators tightened cage specifications considerably. Nautilus “closed up the cages considerably, and in 2017 there were a lot of admonishments to keep even hands inside” (^[33] — forum). By 2021, the Mexican government required further cage modifications with narrower bar spacing, possibly in response to a breach incident around 2019 that reportedly resulted in a shark death (^[34] — forum). These tighter cage designs created photographic challenges, as photographers needed smaller dome ports to fit through the viewing windows. One veteran noted that a 6-inch dome was preferable to a 9-inch dome in the tighter cages (^[35] — forum).

Wetpixel Expeditions

Guadalupe was a cornerstone of Wetpixel’s organized expedition program:

• 2006 Wetpixel Great White Shark Expedition — Eric Cheng and acclaimed underwater photographer/cinematographer Norbert Wu co-led two trips aboard the Solmar V in August 2006. The first was a special 7-day expedition (August 18-25) priced at $4,000-4,100, featuring a cinema cage and limited to 16 divers — it sold out completely. A second 5-day trip (August 25-30) was added due to “overwhelming demand” at $2,895 per person, also aboard the Solmar V via Great White Adventures (^[36]; ^[37]). Both trips were unique in that no other boats were scheduled at Guadalupe during August, avoiding the crowding of the September-November season when up to 6 boats might be present simultaneously (^[38]). Steve (“photobeat”) reported from the trip that they had “decent shark action” with sharks every day, and noted that “When AC/DC went on through the UW speaker the sharks seemed to arrive as if on cue” (^[39]). On the extension trip, Mo Rocca and a television crew were aboard filming a story for The Tonight Show with Jay Leno, broadcast on November 21, 2006 (^[40]).

• 2018 Wetpixel Guadalupe Sharks Expedition — Led by trip leader Abi Mullens aboard the Solmar V (Pelagic Fleet), August 26-30, 2018, focusing on great white shark imagery (^[41]).

Photography at Guadalupe

Lens Selection

Lens choice for Guadalupe shark photography was one of the most frequently debated topics on the Wetpixel forums. The key challenge was that sharks spent most of their time at 10-15 feet from the cage, with close passes being less frequent and unpredictable.

Community consensus generally favored mid-range zoom lenses over ultra-wide fisheyes:

• 16-35mm or 17-40mm (full frame) — The most commonly recommended lens. Eric Cheng called the 16-35mm “a perfect lens for cage use” with his Canon 1D Mark II (^[42] — forum). “DrSteve” on the Wetpixel forums echoed this, reporting that on three trips to Guadalupe with a Canon 5D, “I got the best results with my 17-40 zoom. The 15mm fisheye is a little too wide unless the sharks come VERY close” (^[43] — forum).

• 12-24mm (DX/APS-C) — Eric Hanauer’s Sport Diver cover shot was taken with this lens; Alex Mustard noted it “worked perfectly in the cage” (^[44] — forum). However, one veteran who used a 10-24mm on DX found himself “wishing for a lens with more reach” and switched to a 16-85mm for subsequent trips (^[45] — forum).

• Medium zoom lenses (17-55mm DX, 24-70mm equivalent) — Offered more reach for distant sharks. Drew Wilson, shooting a Panasonic GH5, recommended a “medium zoom lens” and reported that his popular head-on shark shot was captured at 70mm equivalent: “Even a big great white will look quite small on a 16mm lens when they are 15 feet away” (^[46] — forum).

• Fisheye lenses (10-17mm Tokina, 15mm Sigma, 16mm Nikon) — Fun for when sharks came very close, but most photographers found them too wide for typical encounter distances. As one veteran of multiple trips noted: “The fisheye got no use, I stayed on the 7-14 the entire time. My wife’s compact (G7X) had a more useful range, I thought” (^[47] — forum).

Alex Mustard used Guadalupe as part of his extended Nikon D3 field review in 2008, testing the camera’s high ISO capabilities in the clear blue water. He spent more than 35 hours underwater with the camera across Canada, California, and Guadalupe, shooting with a Sigma 15mm fisheye and Nikon 17-35mm in a Subal ND3 housing (^[48]; ^[49]).

Sergio Ricardo captured a notable great white image at Guadalupe with a Nikon D800E and Nikkor 17-35mm lens in a Seacam housing at 1/250 @ f/8, ISO 200, lit with two Sea & Sea D1 strobes (^[50]).

Alex Suh was featured in Wetpixel’s Full Frame section with an extensive portfolio of great white shark images from Guadalupe, shot with a Nikon D810 in a Seacam housing with a Nikkor 16-35mm lens and Seacam 150D strobes. His work included over-under (split) images, black-and-white portraits, and breaching sequences (^[51]).

Shooting Tips from the Community

Extensive community discussion on Wetpixel yielded practical guidance for photographing great whites at Guadalupe:

• Get low in the cage — Kneeling provides the best angle to capture the shark’s mouth and eyes, which are the most compelling features. “Nobody cares about the top of the shark. The money is in the mouth and the eyes” (^[52] — forum).
• High shutter speed — At least 1/250s to freeze both shark movement and cage motion from swell. Some photographers preferred even faster speeds (^[53] — forum).
• Strobes optional — With surface cage diving in clear water, ambient light was often sufficient. One veteran of nine trips reported seeing only one person use strobes across all his visits. However, strobes could add fill light to reveal the blue color of great white eyes and reduce shadows on the shark’s underside (^[54] — forum; ^[55] — forum).
• Burst mode with continuous autofocus — Essential for capturing mouth-open moments as sharks lunged for bait. Single-point AF or small zone AF was recommended to “punch through” schooling fish acting like backscatter (^[56] — forum).
• Watch for mackerel — Schools of mackerel congregating under anchored boats were a persistent frustration, acting like backscatter and ruining otherwise good shots of approaching sharks. One photographer described them as “in the right place to screw up a shot” on multiple trips (^[57] — forum; ^[58] — forum).
• Manage ISO with changing light — Morning was darker (ISO 400-800), midday allowed lower ISOs (100-200). The direction of available light changed throughout the day depending on which side of the boat was in use (^[59] — forum).
• Protect your dome port — The cage bars were often unpadded, and swell could bounce photographers around. Multiple members warned about dome ports striking cage bars (^[60] — forum).
• Corner position — Try to position yourself at a cage corner for two shooting angles rather than one (^[61] — forum).
• White balance correction in post — Several photographers found that post-production white balance correction in Lightroom was essential for Guadalupe’s blue water (^[62] — forum).

Notable Wetpixel Photographers at Guadalupe

• Eric Cheng — Made multiple trips beginning in September 2003. His travel journal from the November 2004 trip drew praise from Alex Mustard, who singled out images capturing “a different side of the white shark personality.” Cheng shot with a Canon 1D Mark II and 16-35mm lens (^[63] — forum). He co-led the 2006 Wetpixel expedition with Norbert Wu (^[64]).
• Alex Mustard — Tested the Nikon D3 in a Subal housing at Guadalupe in 2008, using the Sigma 15mm fisheye and Nikon 17-35mm. His three-part field review documented how the D3’s high ISO capabilities opened new possibilities for wide-angle shooting in the East Pacific (^[65]).
• Stephen Frink — Visited Guadalupe in 2003 with a Canon EOS-1Ds in a Seacam housing, noting that the resolution of the full-frame files “precipitated my migration to the 1DsMKII I use now” (^[66] — forum).
• Norbert Wu — Acclaimed underwater photographer and cinematographer who co-led the 2006 Wetpixel expedition to Guadalupe (^[67]).
• Marty Snyderman — Led dedicated imaging and editing workshop trips to Guadalupe with Mary Lynn Price (^[68]).
• Ron and Valerie Taylor — Led a Guadalupe great white shark expedition in October-November 2007, organized through San Diego Shark Diving Expeditions. Eric Cheng noted the opportunity: “You’d be silly to miss this opportunity!” (^[69]).
• Mark Strickland, Todd Winner — Notable photographers who participated in the October 2009 Nautilus Explorer trip alongside Doug Ebersole and Kal Attie, with the group experiencing multiple close encounters in the submersible cages (^[70] — forum).
• Alex Suh — Prolific Guadalupe photographer whose over-under and black-and-white great white images were featured in Wetpixel’s Full Frame section. He was also a 360Fly Ambassador filming 360-degree footage at Guadalupe and founded the #SaveMyFins documentary project promoting shark conservation (^[71]; ^[72]).

Safety Controversies

Operator Practices and the “Arms Race” (2008-2010)

By 2010, safety concerns at Guadalupe had intensified. Wetpixel contributor Sterling Zumbrunn reported that “operators are pushing the envelope at Mexico’s Guadalupe Island, the world’s premiere destination for diving with great white sharks. Some operators have called it an ‘arms race’ to make the encounters with the large predators more and more extreme.” Operators pointed fingers at each other over illegal methods, but agreed that “if there is an accident, the Mexican government will likely shut the whole business down, potentially paving the way for poachers to slaughter the sharks” (^[73]).

In 2008, the shark diving operator Shark Diver drew controversy on Wetpixel for publishing misleading blog posts about a shark bite incident in the Bahamas, including a headline “Death on Tiger Beach” when the incident had occurred over 60 miles from Tiger Beach and was not fatal. Eric Cheng engaged directly with Shark Diver’s CEO Patric Douglas, and underwater photographer Andy Sallmon wrote a detailed open letter criticizing the “irresponsible and misleading” reporting. Shark Diver operated at both Guadalupe and the Bahamas and maintained the Guadalupe Island Conservation Fund (^[74]).

The 2016 Cage Breach Incidents

Late 2016 brought two separate incidents of great white sharks entering cages with divers at Guadalupe, both of which went viral and attracted worldwide media coverage including the New York Times.

The first incident occurred in September aboard the Nautilus Explorer and involved a group from Bluewater Dive Travel. A shark entered a submerged cage from the top; images clearly showed bags of chum attached directly to the cage, and the shark likely mistimed its lunge for the bait. The shark became wedged in the cage at the surface until a line was passed around its tail, the cage was dropped back down to depth, and a divemaster squeezed the shark’s gills to allow it to escape (^[75]).

The second incident, on October 4 aboard the Solmar V, involved a shark breaching through the observation window of a surface cage, breaking a bar in the process. The diver, Chan Ming of Shanghai, remained calm, swam out of the cage underwater, and re-entered after the shark escaped through the opened top hatch. The entire incident lasted about 20 seconds. Neither the diver nor the shark sustained serious injuries. Solmar V’s statement noted: “It is also important to note that shark breaches of this magnitude are a one in a million occurrence” (^[76]).

Adam Hanlon’s Wetpixel article noted that “it is perhaps unhelpful to attempt to ascribe blame to any of the parties involved until these investigations have been completed” and emphasized that cage diving with great white sharks was “entirely legal and tightly controlled at Guadalupe” (^[77]).

These incidents led to significant cage design changes across all operators and increased scrutiny by Mexican authorities.

Closures (2021-2022)

In a major setback for the Guadalupe diving industry, the Guadalupe Island Biosphere was closed for the 2021 season. Horizon Charters announced in August 2022 that the closure would be extended through the 2022 season as well, with their appeal overruled by a federal judge. Other charter companies were also separately appealing the decision, but Horizon suspected that given the unsuccessful appeal, “this will be the precedent applied to all similar appeals” (^[78]).

Film and Television

Guadalupe has been the subject of significant film and television productions documented on Wetpixel:

• “Island of the Great White Sharks” (2008) — Produced by Richard Theiss of RTSEA Productions, shot entirely in HD video at Guadalupe. Featured shark scientist Peter Klimley of UC Davis and Mexican biologist Mauricio Hoyos Padilla. The film was reviewed on Wetpixel by David McGuire of Shark Stewards, who praised its balance of excitement and conservation messaging: “Educational yes, but excitement and information pepper this independently produced film” (^[79]).

• “Killer Shark Live” (2005) — Described as “the world’s first live great white shark series,” broadcast on Channel Five in the UK from October 2-9, 2005. Shot by Wetpixel community members at Guadalupe (^[80] — forum).

• “Shark Culture” (2011) — Produced by Joe Romeiro’s 333 Productions, featuring Cal Ripfin/Shredder from Guadalupe with oceanic white tip footage and a “speed drawing” animation sequence (^[81]).

• “Finisterra” (2016) — Short film by Wetpixel member Erick Higuera, filmed partly at Guadalupe Island along with Mag Bay, Cabo San Lucas, the Revillagigedo Islands, and the Sea of Cortez, using a Canon 5D Mark III, Canon 16-35mm, Sigma 15mm fisheye, Nauticam housing, and Zen 230mm Superdome port (^[82]).

• Christian Petron won the Gold Prize at the 37th Festival Mondial de l’Image Sous-Marine (2010) for the film Great White Sharks of Guadalupe (source — referenced in timeline).

• The Tonight Show with Jay Leno (2006) — Mo Rocca and a television crew filmed a story at Guadalupe during the Wetpixel extension trip in August 2006, broadcast on November 21, 2006 (^[83]).

• Astronaut Terry Virts (2017) visited Guadalupe aboard the Solmar V to film great whites in 360-degree video and from the air. He described the experience: “To be underwater, out of our natural land domain, in the presence of one (or often several) of Earth’s most magnificent and deadly creatures is just impossible to put into words” (^[84]).

Travel Considerations

The remoteness of Guadalupe Island presents unique logistical challenges for photographers:

• Customs duties — Beginning around 2019, Mexican customs officials at Baja California airports (Cabo San Lucas and La Paz) began enforcing a policy of charging a 16% import fee on underwater camera housings, based on an interpretation that housings were not camera accessories. This affected many Guadalupe-bound photographers. Nautilus Liveaboards published detailed guidance for travelers, arguing that housings are camera accessories under Mexican and international law, and provided a Spanish-language document to present to customs officials. Some photographers reported being charged hundreds of dollars; one was charged $570 on a Nauticam housing as late as 2025. Others recommended carnets or the CBP Form 4457, though the latter was only relevant for US re-importation and had no legal standing with Mexican customs (^[85]).

• Seasickness — Community members consistently recommended dramamine for the 18-24 hour crossing, “even if you don’t normally get sea sick, the boat ride out might easily push you over [the] line.” Aft cabins were preferred over bow cabins for stability; one forum member reported that “even one of the hardiest sailors (charter boat captain) got sick” on the crossing (^[86] — forum; ^[87] — forum).

• Communications — No cellular or Wi-Fi reception at the island. Satellite phones (Iridium, Thuraya) or BGAN terminals were the only communication options unless the vessel provided satellite internet, as Nautilus Explorer did for a small fee. Rental costs for satellite phones were approximately $150 for two weeks (^[88] — forum).

• Thermal protection — Despite warm surface temperatures, extended time in cages without much movement caused chill. Experienced Guadalupe divers recommended at least a 7mm wetsuit; some preferred drysuits. Eric Cheng recommended bringing both wet and dry suits. One forum member noted that “by the end I was beginning to wish I had a dry suit, an hour in the cage not moving much in 70 degree water for 3 days and you start to feel the cold” (^[89] — forum).

• Equipment redundancy — The remoteness of the location made backup equipment essential. Multiple forum members stressed bringing spare camera bodies, extra batteries, multiple memory cards, and backup strobes. As one member put it: “better to have and not need than need and not have” (^[90] — forum).

Comparison with Other White Shark Destinations

Guadalupe’s clear blue water distinguishes it from other white shark destinations. South Australia and South Africa (False Bay, Gansbaai) also offer cage diving, but typically with lower visibility and greener water. Alex Suh noted: “I love the sun and clear water in Isla Guadalupe unlike South Africa which usually has green waters” (^[91]). Cape Town cage diving operations pack more divers per cage (up to 8 people) compared to Guadalupe’s typical 2-4 person cages, and the water tends to be murkier with more chum-related particles (^[92] — forum).

Nautilus Explorer cages at Guadalupe were specifically “designed with photographers in mind” with larger viewing windows and fewer divers per cage compared to South African operations (^[93] — forum).

Within the shark photography community, Guadalupe was often discussed alongside Tiger Beach in the Bahamas as the two premier shark photography destinations, though they targeted different species and diving styles. Tiger Beach offered open-water tiger shark encounters without cages, while Guadalupe required cage diving due to the size and nature of great white sharks. Tiger Beach was also considered “much easier” for photography due to fewer restrictions on positioning and equipment (^[94] — forum).
