Big fish schools, bull shark season, and a community-built marine park on Baja's East Cape
Updated Jan 23, 2026 • 17 sources
Overview
Cabo Pulmo is a tiny, off-grid beach community on Baja California Sur's East Cape, anchored by Mexico's Cabo Pulmo National Park and the UNESCO-listed protected areas of the Gulf of California. The park protects the only coral reef system in the Gulf of California and one of the northernmost reefs in the eastern Pacific. After the community pushed for a no-take reserve, fish biomass rebounded dramatically, and today divers drop into swirling "jack tornadoes", turtles, rays, and seasonal shark action. Most dives are short panga rides to reefs, pinnacles, and the El Vencedor wreck. For non-divers, snorkeling is excellent on calm days, and the quiet desert coastline is perfect for stargazing and road-trip side quests to Santiago's oasis, Sierra de la Laguna hikes, and La Paz whale shark season.
Cabo Pulmo National Park protects the only coral reef system in the Gulf of California, a rare hard-coral ecosystem in a desert coastline setting.
After protection and local enforcement, studies reported fish biomass increases on the order of 460%, creating the big-school spectacle divers come for.
Bull sharks are the marquee winter encounter, with strict guide-led protocols.
A straightforward drive from Los Cabos (SJD) makes Cabo Pulmo a high-impact, low-crowd add-on to a Baja trip.
