The remote Revillagigedo archipelago, known to divers as Socorro, pairs giant Pacific manta ray encounters with scalloped hammerhead schools patrolling offshore pinnacles like Roca Partida and Punta Tosca. Liveaboard trips from Cabo San Lucas require long Pacific crossings but reward divers with some of Mexico's wildest pelagic action. Spring from April through May aligns hammerhead activity with warming water and peak manta season.

Up to 88% sighting chance in Socorro / Revillagigedo (Mexico). Best months: April, May, March.
Hammerheads appear November through May, with the strongest schools typically from March through May at pinnacles like Roca Partida.
Most trips run 8 to 10 days including two days of Pacific crossing from Cabo San Lucas, costing roughly 3,200 to 5,000 US dollars (2026 prices).
Roca Partida and Punta Tosca are the classic hammerhead pinnacles, often combined with giant manta encounters on the same itinerary.
Giant oceanic mantas, bottlenose dolphins, whale sharks, and occasional tiger sharks share the Revillagigedo archipelago.
Advanced open water and comfort in current and blue-water drifts are standard requirements on Socorro liveaboards.
