Isla Espiritu Santo

"This archipelago off the coast of La Paz (which takes the name of the main island) is a protected UNESCO Biosphere Reserve. While the islands are uninhabited by humans save for a small fishing camp made of temporary structures, they’re home to a great variety of flora and fauna. In addition to dolphins, frigate birds, and ring-tailed cats, you’ll find the only known black jackrabbit population in the world. Celebrated eco-friendly activities company Cabo Expeditions leads daylong archipelago tours that include exploring the mesmerizing volcanic landscape, a ceviche lunch, and an opportunity to swim on Ensenada Grande Beach—often cited as one of the world’s most beautiful—plus guided snorkeling with the incredibly playful pups at the Los Islotes sea lion colony."
