One of the most important coral reef systems in North America, this UNESCO World Heritage Site off the East Cape features a thriving ecosystem after decades of conservation efforts. Divers encounter bull sharks, manta rays, sea turtles, and enormous schooling fish. The remote village of Cabo Pulmo maintains strict no-take zones that have allowed the reef to recover dramatically.
Cabo Pulmo National Marine Park protects a 20,000-year-old hard coral reef on the East Cape of Baja California Sur, roughly 100km northeast of San José del Cabo and reached by a long stretch of washboard dirt road. It is one of the few living coral reefs on the Pacific coast of North America and the site of one of the most striking marine recoveries ever recorded: after the local fishing community petitioned for protection in 1995 and enforced a full no-take zone, total fish biomass in the park increased several-fold within two decades. The reef now forms part of a UNESCO World Heritage listing.
Diving and snorkelling are the reason to come. Boats run out from the beach at Cabo Pulmo village to a handful of named sites — El Bajo, Los Morros, El Cantil, Las Casitas — where fingers of Porites coral rise from sand in 10-25m of water. The signature sight is a dense tornado of bigeye jacks, thousands of fish tight enough to blot out the surface, along with schooling snapper and grunts in comparable numbers. Green and hawksbill turtles are common, mobula rays pass in seasonal aggregations, and from roughly October through February bull sharks gather at the deeper sites. Whale sharks and humpbacks appear in winter.
All activity must be arranged through operators based in the village; outside dive shops and boats are not permitted to work inside the park. Park fees run about $10-15 USD per adult and $5 per child, paid on top of dive or snorkel charges. A dive day is a full commitment of six to eight hours; a shore or boat snorkel takes about half that. Morning departures are standard because afternoon wind consistently roughens the water and cuts visibility.
The village itself is tiny and deliberately undeveloped — a scatter of cabañas and small restaurants, largely solar-powered, with limited mobile signal, no bank and no fuel station. Staying a night or two is the practical way to dive more than once. Anchoring, fishing, jet skis and glass-bottom boats are all prohibited within the park boundaries, and gloves and reef contact are strictly forbidden.

When to visit
Water is warmest and clearest from roughly August through November, while bull shark season runs October to February and winter brings humpbacks and cooler water requiring a thicker wetsuit. Take the morning departure in every season, as afternoon wind reliably roughens the surface and reduces visibility.
Accessibility
Cabo Pulmo is reached by an unpaved washboard road best driven in a high-clearance vehicle, and the village has sand streets, no paved paths and no adapted facilities. All boats launch directly off the beach, requiring passengers to wade and climb into a panga, so the park is not accessible to wheelchair users. Accommodation is in simple solar-powered cabañas, most with stepped entrances.
Frequently asked questions
How long does a visit take?
A two-tank dive day runs six to eight hours from the village, while a boat snorkel trip takes about three to four. Given the rough dirt access road, most visitors stay overnight in Cabo Pulmo rather than day-tripping from Los Cabos.
Is it worth it for kids?
Snorkelling suits confident swimmers from around eight upward, and the shallow inshore sites are calm on a good morning. The remote village has few facilities and limited entertainment beyond the water, so younger children may find it long.
Can outside dive operators be used?
No. Only operators based in Cabo Pulmo village hold permits to work inside the park, and boats from Los Cabos or La Paz are not allowed to run trips there. Booking is done directly with the village shops.
What does entry cost?
The national park fee is roughly $10-15 USD per adult and about $5 per child, charged in addition to dive or snorkel trip prices. Fees are collected locally and support park enforcement.
