Los Petenes biosphere reserve, Biosphere reserve in Campeche, Mexico
Los Petenes is a biosphere reserve on the northwestern coast of Campeche, Mexico, covering coastal wetlands, mangrove forests, and open water along the Gulf of Mexico. The landscape shifts gradually from open sea to flooded grasslands and freshwater springs as you move inland.
The area was designated a biosphere reserve in 1999 after conservation efforts drew attention to its ecological and archaeological value. Among the sites protected is Isla Jaina, a Maya island used as a burial ground along the coast.
Fishing villages dot the edges of the reserve, and local families have worked these waters for generations using small boats and traditional nets. The daily rhythm of life here is shaped by the tides and the seasons more than by any calendar.
The months between October and May bring cooler and drier conditions, which make moving through the wetlands easier. A guide is strongly recommended since many paths through the mangroves and lagoons are hard to follow without local knowledge.
The reserve takes its name from formations called petenes, small islands of vegetation that grow around underground freshwater springs in the middle of saltwater or brackish zones. These formations appear in only a few places in the world: the Yucatan Peninsula, Cuba, and Florida.
