Sea of Cortez Liveaboard October 18-25, 2025
Get ready to swim in “the world’s aquarium”. The Sea of Cortez is bustling with friendly sea lions, whale sharks and schools of fish. It is located between mainland Mexico and the Baja California Peninsula and is one of the easiest places to reach to see a variety of marine life from the U.S.
Known as one of the most biologically diverse seas in the world, there are over 5,000 species of marine animals found here. In addition to its diverse marine life, the Sea of Cortez is known for its unique geography, with deep canyons and steep underwater cliffs.
The Sea of Cortez is also a popular destination for recreational activities such as sportfishing and kayaking. There are numerous islands and coastal towns along the sea’s shores that offer opportunities for visitors to explore its natural beauty and cultural attractions.
The Sea of Cortez is flooded with marine life including hammerhead sharks, whale sharks, mobula rays and dolphins. The most popular diving spot in this area is El Bajo. It is the best place to see schools of hammerhead sharks.
La Paz Bay is where you can swim with whale sharks and Los Islotes is where you will definitely encounter sea lions. In fact, the Sea of Cortez is the only place in the world where you can swim and have physical contact with sea lions.

Day 1 - Boarding Day!
Please check into SeeCreatures Cabo by 4:30 pm latest for coach transfer to
La Paz where our hosties will be waiting on the back deck for you with trays of
margaritas and champagne.
Days 2-7 - The Sea of Cortez!
Everyday will be different and your captain and dive guides will update
your itinerary to maximize animal and diving encounters and minimize
any challenges with weather. This is a stunning time of year to dive the Sea
of Cortez with water temps in the high 70’s or 80’s and the beautiful cobalt
blue typical of summer. One of the nicest things about this time of year is that
the seas are generally very calm without any motion aboard our heavy steel
stabilized ships. You can expect to visit Loreto, San Pedro Martir*, Bahia de Los
Angeles, Las Animas, San Franciscito, Espiritu Santo and La Reyna.
Day 8 - Last Day
Morning breakfast. Disembark at 8:30 am in La Paz and complimentary transfer
back to either SeeCreatures Cabo San Lucas or SJD Airport.
