Cabo Pulmo —
North America's Living Reef

About Cabo Pulmo National Marine Park

Cabo Pulmo National Marine Park protects the only living coral reef on the Pacific coast of North America — a 20,000-year-old ecosystem that was on the verge of collapse in the early 1990s when the local community made the extraordinary decision to stop fishing entirely and advocate for the area's protection. The park was established in 1995. In the 30 years since, the results have been nothing short of miraculous: marine biomass has increased by 460%, making Cabo Pulmo one of the most successful marine recovery stories in the world and the subject of ongoing scientific research and international conservation attention.

The reef system extends along a 27-kilometer stretch of coastline on the East Cape of Baja California Sur, encompassing nine distinct reef structures at depths ranging from 5 to 25 meters. The marine life is extraordinary both in variety and in density — bull sharks, hammerhead sharks, enormous schools of bigeye jacks, manta rays, whale sharks, sea turtles, moray eels, garden eels, spotted eagle rays, and hundreds of species of reef fish inhabit the park's waters. The experience of diving here is unlike anything else on the Baja peninsula: the visibility is typically 30–60 feet, the water temperature ranges from 68°F in winter to 84°F in summer, and the sheer abundance of life creates an underwater landscape that feels truly wild.

The village of Cabo Pulmo itself is small — perhaps 100 permanent residents — and has deliberately resisted the development that has transformed most of Los Cabos. There are a handful of casitas and small dive lodges, one or two restaurants, and a collection of dive operators all staffed by members of the local community. This is not a tourist infrastructure — it is a working fishing village that has chosen conservation over commerce and built a sustainable ecotourism economy as the result.

Top Things To Do at Cabo Pulmo

Scuba Diving the Coral Reef

Diving Cabo Pulmo is the primary reason most visitors make the trip and it delivers on every dimension of the experience. The park's nine reef structures each offer a distinct character: El Cantil (The Ledge) drops from 15 to 30 meters along a dramatic wall covered in gorgonian fans and black coral; La Esperanza features dense coral gardens at 10–18 meters with extraordinary fish diversity; El Bajo — the deep site — is where large pelagic species including hammerhead sharks are most frequently encountered during summer months. All dives within the park are conducted with certified local guides, which is both required by law and genuinely valuable given the guides' intimate knowledge of where specific species are found at different times of year.

Dive operators in Cabo Pulmo charge approximately $75–$95 for a two-tank guided dive including equipment, and all are run by members of the local community — your dive dollars go directly to the families who chose conservation over fishing three decades ago. Book in advance during peak season (November through April); walk-in space is sometimes available in shoulder season. Bring your certification card; the park's guides will ask to see it before taking non-certified divers in the water.

Snorkeling with Bull Sharks

From approximately November through March, bull sharks aggregate in Cabo Pulmo's waters in numbers that have to be seen to be believed — schools of several hundred sharks have been documented at La Boca and nearby sites. Guided snorkel tours specifically targeting the shark aggregations operate during this season and offer one of the most extraordinary wildlife encounters available anywhere in the world. The sharks are large, plentiful, and entirely habituated to human presence — they move around snorkelers with complete indifference, creating photographs and memories that last a lifetime. Tours cost approximately $55–$75 per person and operate with strict protocols that ensure both human and shark safety.

Kayaking and Stand-Up Paddleboarding

The calm waters of Cabo Pulmo bay make for excellent kayaking and SUP conditions, particularly in the morning before the afternoon sea breeze arrives. Several operators in the village rent kayaks and paddleboards and can point you toward the most productive snorkeling spots accessible from the beach. The visual clarity of the water means you can often see large fish and rays from the surface while paddling — an experience that complements rather than duplicates the diving and snorkeling.

Hiking the Desert Coast

The landscape surrounding Cabo Pulmo is as dramatic as its underwater environment — rugged desert mountains running to the sea, cardon cacti forests, and isolated beaches accessible only on foot or by four-wheel drive. A trail from the village leads north along the coast to Playa Los Arbolitos, a remote beach that sees virtually no visitors, approximately 3 kilometers one way. The trail requires sturdy footwear, plenty of water, and an early start to avoid the midday heat. The birding along this stretch is excellent — frigate birds, boobies, ospreys, and pelicans are regularly observed.

Getting There from Casa de Corona

Cabo Pulmo is approximately 1.5 hours from Casa de Corona — drive east on Mexico Highway 1 toward San José del Cabo, then continue on the East Cape road (Mexico 1 eventually becomes a well-maintained two-lane highway through Miraflores and La Ribera, then a dirt road for the final approach to Cabo Pulmo village). A standard vehicle can make the trip in dry conditions; a high-clearance vehicle or SUV is more comfortable on the unpaved final stretch. The drive through the East Cape is itself scenic and rewarding — the Sierra de la Laguna mountains on one side, the Sea of Cortez on the other.

Plan for a full-day excursion: depart Casa de Corona by 7:00–7:30am to arrive in time for a morning dive, snorkel, or kayak session, lunch in the village, and return by mid-afternoon. The combination of the drive, the diving, and the village lunch makes for one of the most memorable days available anywhere in Baja California Sur.
