Main caution: Hotter, more humid months with higher storm risk. Many operators pause or reduce schedules.

Liveaboard-only giant manta and shark encounters inside Mexico's fully protected ocean park
Updated Jan 23, 2026 • 15 sources
Overview
Revillagigedo National Park, better known to divers as the Socorro Islands, is a remote cluster of volcanic peaks in the eastern Pacific. You do not come for coral gardens. You come for close, curious megafauna: giant manta rays at cleaning stations, bottlenose dolphins that sometimes initiate interaction, and a rotating cast of sharks. Access is almost exclusively by liveaboard from Los Cabos. Expect blue-water dives, current, and live skiff pickups, with park rules that cap depth at 35 m and typical dive time at 60 minutes. CONANP lists the main diving season as November to June, with water often around 20°C to 28°C depending on month. Plan a few extra Baja California Sur days before or after for recovery, food, and Sea of Cortez day trips.
Managed by CONANP with fees that fund protection, plus strict interaction rules (no touching or feeding, limits on depth/time, and guided groups).
Cleaning-station diving brings repeated passes by giant manta rays that often approach unusually close when divers stay calm and still.
Dolphins, sharks (silky, Galapagos, hammerheads, and occasional tigers), tuna and jacks can all appear on the same itinerary.
Iconic offshore formations like Roca Partida concentrate life and deliver dramatic drop-offs into open-ocean blue.
