Situated at the end of the Baja Peninsula, Cabo San Lucas is perched where the Pacific Ocean and the Sea of Cortez meet. Warm waters, balmy weather and a preserved habitat create a safe home for a jaw-dropping variety of tropical fish and other sea creatures. This beautiful part of the Mexican Riviera offers particularly fantastic snorkeling spots in the marine preserves of Santa Maria Bay and Cabo Pulmo. Marine explorer Jacques Cousteau once called the Sea of Cortez the “the aquarium of the world” due to its ideal environment for an incredible wealth of marine life including unique creatures like the vaquita marina, a tiny porpoise listed as an endangered species. Following are the major reef snorkeling spots in Cabo San Lucas.
