It's Dive o'clock in Baja California - Mexican Dive Expedition with a Marine Biologist

It's Dive o'clock in Baja California, Mexico!

Join us in October 2019 for an epic dive expedition with a marine biologist

6-Day Dive Expedition, 24 - 29 October 2019, 1695 USD pp, Baja California, Mexico

Experience the wild side of Mexico and join us on this exclusive dive trip along the West coast of Mexico, the more budget-friendly alternative of the Galapagos. Get involved in whale shark conservation while snorkeling with them, dive with sea lions and maybe even see dolphins and rays while a marine biologist explains you all about marine life and conservation in this unique area.

This dive expedition takes you off the beaten track! It is no wonder Jacques Cousteau described the Sea of Cortez as the 'Aquarium of the world'. Baja California is the peninsula separating the Gulf of California / Sea of Cortez and the North Pacific Ocean. It's raw, it's natural and it attracts the bigger marine life species - what's on your bucket list?!

Dive with us as we head off to an area that only a few others get to explore. We offer an incredible land-based eco-adventure with various boat trips, perfect for non-diving partners to join and cheaper than a liveaboard. Learn about and join marine conservation efforts while you enjoy a fun-filled exhilarating dive trip.

You have the opportunity to see the raw beauty of the Gulf of California through the eyes of a marine biologist. This expedition is as eco-friendly as possible but we are not going to hug any trees - well, maybe a sea lion. Expect an incredible adventure and the most beautiful interaction with whale sharks and sea lions.

Dive o'clock Expedition

Join us on our first special and exclusive dive trip where diving with big animals and marine conservation meet

Raw beauty awaits you in Baja California! It’s been said that the Gulf of California, also known as the Sea of Cortez, is one of the most biologically rich bodies of water on our planet. Indeed, Jacques-Yves Cousteau himself dubbed this sea “The world’s aquarium”. There are close to one thousand species of fish, several thousand species of invertebrates and a bounty of majestic animals such as various species of balleen whales, pods of dolphins, aggregating whale sharks, colonies of sea lions, mobula rays, manta rays, seabirds and more.

We are committed to providing serious fun and memories that will last a lifetime for any outdoor adventurist. All components of our diving expedition contribute in some way to the conservation of the species and habitats that we visit be it through collaborative research, awareness and education or by direct donations to vital local conservation efforts on the front-line of ocean conservation in the region.

Day-to-day Itinerary

Day 1 - Welcome Cocktail & Expedition Kick-Off

Thursday the 24th of October 2019 we will meet at 17:00 at our hotel in San José del Cabo, Hotel Hampton Inn.
Jay and Marlies will welcome you with a tasty cocktail/mocktail and a presentation about the expedition and marine life in the area.

We will then head out together for a welcome dinner at a Mexican restaurant in San José Del Cabo, famous for its delicious, authentic Mexican cuisine and tasty margaritas. Time to relax and getting to know each-other while our expedition officially kicks-off.

Day 2 - Diving the World Famous Cabo Pulmo National Park

We will enjoy an early breakfast in our hotel before setting off to Cabo Pulmo National Marine Park (approx 2 hours driving) for scuba diving or snorkelling.
Experience the amazing sea life here including schools of jacks or “fish tornados”, eels, turtles and an abundance of tropical fish. Reef sharks, whale sharks and rays have also been known to make their appearance!

After two dives we will return to the beach for lunch. After lunch we will head back out for a relaxing afternoon dive before we drive back to the hotel.
You can spend the evening as you like, explore some of the Spanish colonial architecture of San José del Cabo or join us for dinner/drinks.

Day 3 – Diving with Sea lions at San Rafaelito / Lobos Rock

After breakfast, we will check out at our hotel in San José del Cabo and will head to La Paz (approx 3 hours driving).

When we arrive in La Paz we will check into Hotel Catedral before heading to the stunning Espiritu Santo Archipelago National Park just off the coast of La Paz. Espiritu Santo is a UNESCO World Heritage Site since 2005 and widely considered to be the Jewel in the Crown of La Paz.

Our first dive site will be at Swanne reef where we can find an abundance of fish and invertebrates and a sandy area filled with Garden eels. Look around for stingrays, try to spot colorful nudibranch and maybe even see a sea turtle along the reef filled with hard corals and sea fans.

We will provide a ceviche lunch on a quiet, if not empty, beach within or close to Balandra Bay. This bay is famous for it's stunning views over the Baja California. We will explore the local beauty and wildlife while heading to San Rafaelito for the second dive. When arriving at San Rafaelito / Lobos Rock you can already see dozens of California sea lions laying on the rock or maybe even jumping in the water. Be careful not to roll off the boat on a sea lion with your dive gear, they are literally everywhere! Enjoy the wildlife show in its natural surrounding. Swimming with the playful juveniles is so much fun. An action camera is the best choice here. They are fast!

After diving with the playful juveniles we will head back to the hotel in La Paz where you can fresh-up before joining us for dinner and a visit to a traditional mezcaleria. You can also spend the rest of the afternoon and evening at your own pace, explore the Malecon / boardwalk of La Paz or whatever else your heart desires. All is good, it's your holiday!

Day 4 – Diving the stunning Espiritu Santo Archipelago

After breakfast we’ll meet at the dock at 11:00 to head back to the Espiritu Santo Archipelago, this time we will go on a full day trip to explore the islands further North. This day will be filled with incredible dive sites, snorkeling spots at pristine beaches and exploring stunning bays and coastlines while learning about the history and marine life around Espiritu Santo.

The famous El Bajo seamount will be our first dive site, for the chance of hammerhead or silky sharks!

Los Islotes the northern-most point of the island group that is home to a colony of around 500 California sea lions!!! Here you will get another dive with these magnificent creatures and if you happen to get tired of these playful animals (which we highly doubt) - continue the dive on the reef. After the dive we will head to a beach were we will prepare a delicious lunch for you while you can swim or snorkel in the turquoise blue water.

We will stop by in Bahia San Gabriel, a beautiful sheltered bay that is home to around 1000 breeding pairs of magnificent frigate birds. Don't be surprised if we can spot dolphins, mantas or maybe even a whale from the boat as well, the season is on!

As soon as the sun sets we will get ready for our night dive at the third dive spot of the day. We will stay a bit shallow to hopefully spot some ray species and of course the 'creatures of the night'. Life underwater is definitely different at night, we will tell you all about it.

The return to La Paz will be around 19:30 where you can have dinner and spend the evening as you please. You are also welcome to join us of course.

Day 5 – Snorkel with Whale Sharks and Contribute to Whale Shark Conservation


After breakfast we’ll meet at the dock at 09:00 to board the boat for our special whale shark excursion. You will have multiple opportunities to snorkel at a safe distance from whale sharks and be involved in conservation work. The whale shark excursion lasts around three hours. After swimming with the mighty fish, we will go back to the port and have lunch in a restaurant on the Malecon / boardwalk.

In the afternoon we will head on to the beautiful Balandra Bay! This landmark is reachable by a 45 minutes rocky hike up the hills of Balandra. Now you can really see those stunning views over the Baja California. Take photos of this incredible scenery before heading back to the hotel.

Upon our return in La Paz there is time to refresh, relax and have dinner on your own while we prepare the Expedition wrap-up held at 8 PM. During the wrap-up we will present how many whale sharks we have encountered, the collected research data, contributions to whale shark conservation and sea lion rescue and more. Of course this is the perfect moment to reflect on our trip, sign logbooks and have a last cocktail/mocktail all together before preparing for departure the next day.

Day 6 – Departure Day

Breakfast at your own pace and then depending on departure flight times you’ll head back to San José International Airport for your return flight. It’s time to say goodbye to new friends and to your hosts and we are certain you’ll take many special memories away with you.

Whale Shark gift when the trip is confirmed!

When we can confirm our trip, we have four participants, we will send you this lovely whale shark necklace to show your excitement for seeing the biggest fish in the world.


Jay partnered with a local accessories and jewellery designer, Gina Minivora of Minivoro Accesorios, to produce these gorgeous whale shark pendants. They are handmade from polymer clay and coated in resin, so are resistant to humidity and very durable, with internal metal reinforcements in weaker points such as the fins. Polymer clay is non-toxic, even if ingested.

The pendants are roughly 1.25 inches in diameter and consists of a disc which represents the Blue Planet with a whale shark mounted on top. “Whale Shark Diaries” will be etched on the rear of the piece or you can have it personalized for an extra fee. The pendant is mounted on an adjustable black waxed cotton cord and will come in a small paper gift box.
