Travel - Explore The Sea of Cortez and Baja - Liveaboard 19 Sept - 1 Oct 2026

$300.00 USD


Yes, 2026 -- this trip only happens 3x per year about the Rocio del Mar and it is already fully booked with groups until 2026 because of the special nature of this trip.

Jacques Cousteau referred to the Sea of Cortez as the World's Aquarium because of it's incredible biodiversity.

Now, you can experience this for yourself on this 11 days of diving aboard the famous Rocio del Mar liveaboard dive boat!

We will depart from Puerto Peñasco, Sonora, Mexico on 19 Sep 2026 and end up in San José del Cabo, Baja Sur, Mexico on 1 Oct 2026.  Ground transportation from Phoenix will be available so you can fly into Phoenix and then return by air to Phoenix from San José del Cabo.

Here's a brief description of what you can expect on this trip:

Each day you will awake to a fantastic sunrise amongst some of the most breathtaking scenery in the world with cear skies, deep blue seas, and terrain only millions of years could create. Enjoy three to four dives daily as we move from island to island. Dive on untouched walls and reefs abounding in marine life. The north is a macro photographer's dream with nudibranchs, colorful blennies, dancing jawfish, and sea horses. Throughout the course of this adventure, we should encounter large and small whale species, snorkel with whale sharks, dive with playful sea lion colonies and see countless eels, octopus, fish, and jumping mobula rays.

The bio-diversity between the northern and southern Sea of Cortez is incredible and diving the entire Baja is spectacular! The sea life we witness on the surface from the boat, dinghies and/or snorkeling is also breathtaking.

We can see dolphins, sea lions, pilot whales, humpback whale, fin whales, blue whales, sperm whales, orcas and flying mobula rays. There are also incredible birds including blue and brown footed boobie birds, cormorants, frigate birds and the endemic yellow footed gulls.

In the south we dive the national park in Loreto and guests can spend a nice evening walking and dining in Loreto. We do a night dive with mobula rays and dive wrecks Fang Ming and Salvaterra.

If you wish to hike the remote islands during surface intervals, there is always a dinghy available to take you to shore. We also have kayaks to take a serene cruise around the islands. Between activities, get spoiled with amazing meals and the best crew in the industry.

One of the most popular questions we receive is about water temperature!

The Sea of Cortez is a very seasonal sea which means it changes rapidly based on the seasons. For trips in September, temperatures range from 76-78 degrees Fahrenheit in the north and warms as we go south. In October, the south remains in the low 80's and the northern temperatures can go as low as 72-24.

The Sea of Cortez has vertical thermoclines! You can see the water shimmer before you feel it. There are cool as well as warm currents. During a single dive, experiencing a temperature difference of 10 degrees is quite normal. But don't worry, the cool thermoclines don't usually last long.

The price for this trip is $4895.00 per person, double occupancy.
