Called the “Aquarium of the World” by Couteau, the Sea of Cortez hosts 850 marine species and the largest variety of whales and dolphins on Earth. It’s the perfect place for a liveaboard adventure.
The Sea of Cortez, narrow yet deep, is home to a variety of dive sites from exposed pinnacles with heavy current to protected coral reefs. Winter sees frequent visitors from the open ocean including humpback and sperm whales. These months also offer mobula sightings near Cabo Pulmo. And each fall brings whale sharks to El Bajo and hammerheads to the south, but sightings are not guaranteed. In addition, more than 400 sea lions call the area home. A liveaboard is the best way to dive the Sea of Cortez due to the number of roaming species and distance between sites. Typical itineraries last 7 to 10 days, and the best time to visit is from August to November.
