An ancient reef in the eastern Pacific
The defining feature of Parque Nacional Cabo Pulmo is its hard coral reef, lying just offshore along the eastern flank of the Baja California Peninsula between Pulmo Point and Los Frailes Cape in the Gulf of California.between Pulmo Point and Los Frailes Cape Scientific descriptions characterise this reef as one of the few living coral reefs remaining in North America and the only hard coral reef along the Baja California Peninsula, giving the park an exceptional position in regional marine geography.only hard coral reef of the peninsula Geological and ecological studies estimate that the coral community here has been established for tens of thousands of years, making it among the oldest known reef structures in the eastern Pacific.
The reef system at Cabo Pulmo is associated with bars of extruded igneous rock running through the bay, providing a foundation on which corals and other organisms have grown and formed complex underwater ridges.bars of extruded igneous rock These structures lie at varying depths, with shallow sections nearer Punta Los Frailes and deeper sections extending off Cabo Pulmo itself, creating gradients of habitat for fishes, invertebrates and marine plants. The reef sits close to the Tropic of Cancer, and its position in warm subtropical waters of the Gulf of California contributes to the diversity of species recorded in the park.

International recognition and conservation status
Beyond its national status, Parque Nacional Cabo Pulmo forms part of a larger ensemble of protected areas recognised by international conservation agreements. The marine park is included in the Islands and Protected Areas of the Gulf of California World Heritage site, an inscription that highlights the exceptional marine ecosystems of this region.World Heritage site listing It is also listed as a Ramsar wetland of international importance under site number 1,778, with documentation noting its status as one of the only coral reefs in the eastern Pacific and the sole reef of its kind within the Gulf of California.Ramsar site number 1778
Regional conservation materials describe Cabo Pulmo as an area of national and international relevance because of its coral reef system and long-established marine communities.area of national and international relevance Management programmes prepared for the park in the 2000s detail measures for regulating activities in the reef and surrounding waters, aiming to preserve both its biological richness and the physical structure of the reef bars. The combination of Mexican legal protection, World Heritage recognition and Ramsar status places Parque Nacional Cabo Pulmo among the better-documented marine protected areas on the Baja California Sur coast.
