What is Cabo Pulmo National Park?
Located approximately 60 miles north of Cabo San Lucas on the east coast of Mexico’s Baja California Peninsula, Cabo Pulmo National Park is a beacon of marine biodiversity and a testament to successful conservation efforts in a marine reserve in Mexico.
Established in 1995, this protected area spans over 71 square kilometers (27.46 square miles) of terrestrial and marine habitats, encompassing the Cabo Pulmo Reef, one of the oldest and most vibrant coral reefs in North America, estimated to be around 20,000 years old.
Recognized as a UNESCO World Heritage Site in 2005 for its outstanding marine ecosystem, Cabo Pulmo's UNESCO listing underscores its global value as a conservation treasure. The park is a unique fusion of geographical wonders where the Sea of Cortez meets the Pacific Ocean.
Its reefs are renowned for their "fingers" of coral atop rock formations that run parallel to the coast, creating an underwater labyrinth teeming with life. This intricate reef structure provides a haven for a staggering array of marine species, from microscopic plankton to majestic whale sharks.
Cabo Pulmo serves as a critical nursery for fish larvae, supporting not only local but also regional marine populations throughout the Gulf of California. The area is a living laboratory for scientists and a sanctuary for endangered species, showcasing the resilience of nature when given the chance to heal. Visitors to Cabo Pulmo are invited to dive into this underwater paradise, experiencing firsthand the awe-inspiring abundance of marine life and the thriving ecosystems that make this park a jewel of Mexico's natural heritage.

A Conservation Success Story
The establishment of Cabo Pulmo National Park is a testament to the power of community-driven conservation. In the 1980s, as marine life dwindled due to overfishing and habitat destruction, the local residents of Cabo Pulmo realized that their way of life was unsustainable.
Collaborating with academics from the Autonomous University of Baja California Sur, they learned about the critical importance of their reef ecosystem. Biologists explained how the reef provided essential environmental services and the damage caused by activities like anchoring and heavy fishing.
Despite initial resistance, after all, fishing was their livelihood—the community embarked on a remarkable journey of transformation. In 1995, they successfully petitioned the Mexican government to designate Cabo Pulmo as a protected National Marine Park. The community agreed to cease commercial fishing and adopted a no-take zone policy, allowing the reef and its inhabitants to recover.
The impact of this conservation effort has been extraordinary. Studies have shown a 460% increase in total fish biomass within the park—a recovery unparalleled anywhere else in the world. The return of Cabo Pulmo's marine life includes not only abundant fish populations but also the resurgence of large predators like sharks and groupers, essential for a healthy marine ecosystem.
