Roca Partida

A near-vertical pinnacle rising from over 50m of open ocean, roughly 40km from Socorro Island itself — the most remote of the Revillagigedo dive sites. Known for stacked whitetip reef sharks resting on ledges, schooling hammerheads, and dense bait balls that draw in Galapagos and silvertip sharks.
