Safari Overview

Travel to Guadalupe Island and swim with one of the world's most respected and enigmatic predators: the Great White Shark. Guadalupe Island is located in the Pacific Ocean off Mexico’s Baja Peninsula. With its clear blue water, subtropical temperatures, and an abundance of Great Whites, the protected waters surrounding Guadalupe Island is one of the absolute best places to observe and photograph these awe-inspiring animals.

We welcome anyone interested in sharks regardless of diving experience. Scott Davis and Ted Cheeseman are perfect leaders for this unique adventure, both having backgrounds in marine biology and decades of field experience in photography

• Get up close and personal with the revered predator of the sea – the Great White Shark.
• Spend the week aboard the luxury vessel, Nautilus Explorer, with gourmet cuisine, and lavish accommodations.

Detailed Itinerary

A glimpse into our journey

Fly to San Diego and travel to Ensenada, Mexico

Sep 6

Cheesemans' Ecology Safaris supports World Cetacean Alliance

Arrive in San Diego. Transfer to the Best Western Plus Island Palms Hotel and Marina for a welcome reception with drinks and snacks. If you would like to arrive earlier, we can book extra nights. After the reception, you will travel by coach to the dock in Ensenada, Mexico to board the Nautilus Explorer.

Arrive at Guadalupe Island

Sep 7

Nautilus Explorer ship

Sail to Guadalupe Island and arrive about dinnertime. You can spend time on the deck searching for sea birds such as cormorants, boobies, and auklets along with occasional pods of dolphins or enjoy the ride indoors in the lounge or library.

Guadalupe Island is a volcanic island with a rugged landscape located 180mi off the west coast of the Baja Peninsula and about 250mi southwest of Ensenada. It consists of two ancient overlapping shield volcanoes, the largest, Mount Augusta, rises to about 4,250ft in the north and the smaller, El Picacho, about 3,200ft in the south. The small island measures about 22mi by 6mi with a coastline of rocky bluffs and dense forest above.

Cage diving with Great White Sharks

Sep 8 - 10

Great White Shark cage by Bea Metzger

Spend three full days with Great White Sharks in your choice of surface cages or 30ft submersible cages. Cages are open from 6:30am to dusk, so you have the freedom to spend the day in the cages for as much or little time as you like. In the evenings after dinner, you can scan the shark identification catalogs to try to ID sharks you swam with that day.

Guadalupe is considered one of the best spots in the world to see Great White Shark, possibly because of its large population of pinnipeds. Many island or marine species that live near Guadalupe also frequent the Channel Islands. In stark contrast to the rampant extinction of terrestrial life that happened at the same time, Guadalupe was the last refuge for the Northern Elephant Seal and the Guadalupe Fur Seal in the 1890s. The island has been a pinniped sanctuary since 1975. You can expect between 125 and 150ft of water visibility enabling us to see sharks approach from beyond the anchor line through the clear, cobalt blue water.

Sail back to Ensenada, Mexico and transfer to San Diego

Sep 11

Great White Shark by Scott Davis

We’ll spend most of day at sea en route back to the mainland. Keep your eyes peeled for seabirds, bow riding dolphins and maybe some whales. We’ll arrive in the Ensenada port in the afternoon and our coach will transfer us back to San Diego airport or to the hotel if you are extending your stay.

Fitness Level

Minimal fitness is required to join this shark safari, but your fitness and in-water ability enrich the experience. Getting in the water is not required; we’ve shared this safari with travelers who had wonderful experiences shark watching from the ship. To get the most out of this safari you should be comfortable in the water, and getting in and out of the water via a ladder. We recommend you spend time swimming at a pool or similar before your trip to make sure you are comfortable in water. If you would like to use the 30-foot deep sea cages, you must be SCUBA certified.


Airfare is not included in trip costs. Detailed logistical information and the contact information for our recommended flight-ticketing agent are included in the Trip Materials we will send you. Please let us know if you are arriving earlier or staying later as we are happy to assist you with any extra overnights that you might want to arrange.

Flights you (or a travel agent) book: Arrive in San Diego, California (SAN) no later than 5pm on September 6. Depart from San Diego, California (SAN) after 9pm on September 11.


What are the shark cages like?

The Nautilus Explorer has four shark cages. Two cages are submersible to 30ft and two remain at the surface. In both the submersible and surface cages, you will use a hookah breathing system with air coming directly from the boat’s compressor. Do not worry if you have never used hookah systems before, because we will demonstrate its use and a divemaster will be with you in the cage at all times.

Do I have to be SCUBA certified for this safari?

You do not need a SCUBA certification to enjoy lots of time with the sharks in the surface cages. If you are SCUBA certified, you can also use the submersible cages. If you are not certified, and want to use the submersible cages, you should get SCUBA certified before this safari. The best resources to find SCUBA certification courses near you are the two largest diving certification programs: PADI and NAUI

Is cage viewing safe for the sharks and people?

Our goal is to keep our guests safe and also to protect our growing shark population. To that end, we teach and ask for responsible shark interactions that do not impact or change the behavior of these magnificent animals. We do not use oil, chum or blood. A piece of tuna, wrapped in a burlap sack, is all the sharks need to know we have arrived. We do not feed the sharks at any time. Conservation efforts continue at night when we kick back in the salon and identify who we spent the day with. And should you discover that you hung out with a great white shark not yet catalogued, yes, the naming rights are all yours.



Don’t let a fear of seasickness scare you away! For all but the most sensitive, seasickness is rarely a problem in this region. It’s a good idea to bring medication if you get seasick or are unsure, but you may find that you do not need it after a couple days once you have your “sea legs.” Even those who have experienced seasickness reported that the incredible wildlife and overall experience was well worth the temporary discomfort. Read our suggestions for coping with seasickness and contact us if you have any concerns.



  • Non-smoking policy: We have a strict non-smoking policy. Smoking is not permitted at any time or any place during our tours.
  • Maximum time in nature: We try to spend as much time in nature as possible, sometimes resulting in long days but giving you a more in-depth experience.
  • Itinerary route: The itinerary route, stops, and plans are subject to change by unforeseen circumstances beyond our control, such as weather or road conditions.
  • Additional forms: For some of our tours, you may be asked to fill out additional forms (e.g., medical questionnaire).
  • Medical conditions and travel risks: Travel to remote places is exciting, but it is important to understand and accept the risks, both medical and logistical. Minor medical problems can usually be treated, but because we are often far from medical facilities, there can be no expectation for immediate medical treatment or evacuation, even in cases of trauma. Anyone with health problems needing close medical supervision should not consider going on this tour. Bring enough medication for the duration of the trip for any chronic medical needs, since pharmacies are usually not available. When you send your deposit and signed Reservation/Release Form, you certify to us that you do not knowingly have any physical or other conditions that would create a risk for yourself or for other trip participants.
