Liveaboard Diving in Sea Of Cortez

Sea of Cortez liveaboard diving is about a diver’s paradise World heritage site with sea lions, 100’s of mobula rays, whale sharks, schooling hammerheads, mantas, whales, dolphins and huge fish schools in a narrow stretch of sea between mainland Mexico and Baja California Peninsula down to La Paz.

Scuba diving in the Sea of Cortez and La Paz is all about California sea lions, whale sharks, hammerhead sharks, tuna, manta rays, mobula rays, dolphins, whales and huge schools of fish like the blue stripped snapper, surgeonfish, plus enjoying captivating underwater macro life.

Legendary diver Jacques Cousteau described the Sea of Cortez as the “world’s aquarium“, which speaks for itself. The Sea of Cortez is also the easiest “big animal” destination for divers from the United States to access from airports such as San Diego and Los Angeles.

The Sea of Cortez is sheltered from the Pacific Ocean by the Baja California Peninsula, which connects to California’s southern tip near San Diego. The Sea of Cortez (also known as the Gulf of California) is 1,200 kilometres (750 miles) long, and stretches from Cabo San Lucas on the southern tip of the peninsula to Isla Montague in the far north of the sea.

There are various locations along the Baja California Peninsula to stay in a resort and dive by day boat, but a Sea of Cortez liveaboard cruise gives you the opportunity to reach more dive sites, dive more times per day, whilst having the opportunity to see whales breaching and dolphins or orcas surfing alongside the boat whilst transiting between locations.

The site comprises 244 islands, islets and coastal areas that are located in the Gulf of California in north-eastern Mexico. The Sea of Cortez and its islands have been called a natural laboratory for the investigation of speciation. Moreover, almost all major oceanographic processes occurring in the planet’s oceans are present in the property, giving it extraordinary importance for study. The site is one of striking natural beauty in a dramatic setting formed by rugged islands with high cliffs and sandy beaches, which contrast with the brilliant reflection from the desert and the surrounding turquoise waters. It is home to 695 vascular plant species, more than in any marine and insular property on the World Heritage List. Equally exceptional is the number of fish species: 891, 90 of them endemic. The site, moreover, contains 39% of the world’s total number of species of marine mammals and a third of the world’s marine cetacean species.
