Las Baulas Marine National Park is a vital coastal reserve renowned for protecting nesting grounds of the endangered leatherback sea turtle and offering rich marine and terrestrial biodiversity.
Las Baulas Marine National Park, located on Costa Rica’s Pacific coast in Guanacaste Province, protects critical nesting habitats for the leatherback sea turtle, one of the planet’s largest and most endangered marine reptiles. Established in 1991, the park spans coastal beaches, estuaries, mangroves, and dry tropical forest. Its geography features long sandy beaches such as Playa Grande and Playa Langosta, where turtles return each year to lay eggs. The park’s ecosystem supports diverse flora and fauna including various sea turtles, migratory birds, crocodiles, and several fish species vital to local fisheries. For visitors, the park offers opportunities to witness turtle nesting during the October to March season, wildlife viewing in mangrove areas, guided night walks, and ecotourism experiences. Playa Grande is also celebrated for surfing, drawing enthusiasts of all levels. Las Baulas is adjacent to the Marino Las Baulas Wildlife Refuge and forms part of the larger Tempisque Conservation Area. The park plays a crucial role in environmental education and community-led conservation efforts.
