Cabo Pulmo National Park protects the oldest and northernmost hard-coral reef in the eastern Pacific, on the East Cape of Baja California Sur. A community-enforced no-take reserve since 1995, it became the conservation success story of the Gulf of California—fish biomass rebounded over 460% in a single decade—and is famed for a swirling tornado of bigeye jacks, seasonal bull sharks, and spring mobula aggregations.

Water and air temperature across the year.
Cabo Pulmo National Park sits on the East Cape of Baja California Sur, fronting the Gulf of California (Sea of Cortez). Its reef—hard coral growing atop fingers of volcanic rock that run parallel to shore in progressively deeper water—is roughly 20,000 years old, the northernmost coral reef in the eastern Pacific and one of only three on North America's west coast, hosting about 11 hard-coral species. Designated a national park in 1995, a UNESCO World Heritage Site in 2005 and a Ramsar wetland in 2008, the park spans some 71 km². Its fame rests on a recovery story: a no-take zone enforced by the local fishing community saw total fish biomass climb from 0.75 t/ha in 1999 to 4.24 t/ha by 2009—a 463% increase, the largest documented in any marine reserve—with top predators rebounding roughly elevenfold (Aburto-Oropeza et al., PLOS ONE 2011). Divers come for the dense, healthy reef fish, a year-round tornado of bigeye jacks, seasonal bull sharks cleaning at the El Vencedor wreck, spring mobula swarms, a sea-lion colony, and winter humpbacks passing offshore. Diving is strictly regulated: only authorized local operators, mandatory park guides, no anchoring, no gloves, capped daily access by a per-site lottery, and bottom-time limits. Water is warmest and clearest July–November and cooler and greener in winter and spring.
What makes this dive worth the trip.
25 species you’re likely to encounter on a dive here.
7 signature sites at this destination.
A shallow rocky site with no coral reef, known as the park's sea-lion haul-out: California sea lions are the main attraction, playful and curious around divers and snorkelers. Surgeonfish and Moorish idols are common, with seasonal sardine schools and the occasional spotted eagle ray. A gentle, shallow dive that works well for less-experienced divers and as a finale to a two-tank day.
The most iconic site in Cabo Pulmo: the scattered remains of a tuna trawler that struck the reef and sank in the early 1980s, now lying in sand at around 14 m. The wreck functions as a cleaning station and is the park's prime spot for bull sharks, which gather in numbers during the cooler season. Schools of snappers and yellowtail, groupers, giant morays, stingrays, jacks and turtles surround the structure; tiger sharks are an occasional possibility. A relatively shallow, sandy-bottom site, but the bull-shark draw makes it an advanced experience best dived with a guide.
An offshore series of massive rock formations draped in sea fans and coral, and one of the most reliable places to find the swirling tornado of bigeye jacks. The rocky bars and ledges concentrate groupers, snappers, turtles and stingrays, with seasonal mobula rays and the occasional passing whale shark or bull shark. Surge and current over the exposed structure call for good buoyancy control.
A long, shallow reef bar running across the park—home to a large share of Cabo Pulmo's hard-coral diversity—with gentle coral gardens over rock. Schools of grunts and snappers, groupers, sea turtles and seasonal mobula rays move along the bar. The moderate depth and conditions make it one of the more forgiving sites and a frequent first dive, though current can build with the tide.
A deeper coral-reef bar for more experienced divers, set well offshore. Groupers, snappers, turtles, stingrays and eels populate the reef, with seasonal mobula rays and guitarfish; tiger and bull sharks are an occasional possibility. The depth and exposure make it an advanced site dived when conditions allow.
A coral-and-rock pinnacle near the southern edge of the park, rising from a sandy seabed scattered with large boulders. Schools of African pompano, groupers and snappers patrol the structure, with turtles, eels, lobsters and nudibranchs in the cracks; sardine schools and white-tip reef sharks are seasonal. Its range of depths suits a broad mix of divers.
A shallow, clear reef ridge of cracks, ledges and small caverns that acts as a highway for reef fish—an easy, photogenic dive suited to most levels. Expect bigeye trevally, groupers, morays, snappers, turtles and stingrays among the coral and rock, with nudibranchs and other macro subjects in the crevices. Bull sharks and humpback whales are seasonal possibilities.
