Los Islotes

Los Islotes, the sea lion colony at the north tip of Espiritu Santo, delivers the Sea of Cortez's most dependable joy. Several hundred California sea lions live on the islets, and the juveniles treat visiting divers as the day's entertainment - mouthing fins, blowing bubbles in masks, and corkscrewing through groups in nine meters of water. Below the acrobatics, the boulder reef holds king angelfish, moray eels, and drifts of sergeant majors; a small archway cuts through one islet for swim-through theatrics. Bulls patrol territorially in breeding season and deserve their space. Between the accessibility, the shallow profile, and the guaranteed protagonists, it may be Mexico's best first ocean dive.
