Wilderness Landscape & Natural Heritage
Marismas Nacionales Biosphere Reserve spans the coastal regions between the states of Nayarit and Sinaloa along the Pacific Ocean. It encompasses extensive mangrove forests, lagoons, estuaries, and freshwater marshes, creating one of Mexico’s largest and most diverse wetland systems. The reserve serves as a crucial habitat for migratory and resident bird species, including herons, egrets, pelicans, and several endangered species. It also supports rich marine life such as fish, shrimp, and turtles, linking coastal and inland ecosystems. Historically, this area has been vital to local communities for traditional fishing and agriculture, and more recently, it has gained attention for sustainable tourism and conservation efforts. Visitors to Marismas Nacionales can enjoy guided boat tours through the mangroves, birdwatching, sport fishing, and cultural visits to nearby fishing villages. Notable landmarks include the Teacapan Lagoon complex and the interconnected river systems like the Acaponeta and Baluarte rivers, which sustain the wetland’s hydrology. The reserve’s accessibility from major cities like Puerto Vallarta and Mazatlán adds to its appeal. Ecotourism initiatives focus on balancing visitor experience with protection of sensitive habitats, making Marismas Nacionales an increasingly important model for wetland conservation in Mexico.
