La Amistad International Park, International park in Panama and Costa Rica.

La Amistad International Park covers 401,000 hectares across the Cordillera de Talamanca, including Costa Rica's highest peak, Cerro Chirripó. It is split equally between Costa Rica and Panama and protects tropical rainforest, cloud forest and subalpine ecosystems. The mountains consist mainly of metamorphic and igneous rocks such as schists, gneisses and granites.

The park was created by the governments of Costa Rica and Panama, which merged the Cordillera de Talamanca Reserve and La Amistad National Park into a single entity with shared management. UNESCO inscribed it as a World Heritage Site in 1983, and in 1988 it was declared an International Park for Peace following a UNESCO recommendation.

Three indigenous peoples live inside the park: the Naso, Bribri and Ngöbe-Buglé, in small traditional villages. The Panamanian sector also covers the Naso Tjër Di comarca, a Naso territory. The 15 km buffer zone is farmed by coffee and beef producers and by indigenous subsistence farmers.

The main access point is through Las Nubes in Chiriquí province, where ranger stations provide trail maps and can arrange guides. Bringing sturdy hiking shoes and rain gear is important since weather changes frequently at higher elevations.

The park's remoteness has kept much of it unexplored: the first substantial scientific surveys deep inside were led by the Natural History Museum London, INBio and the University of Panama in the late 2000s, funded by the UK's Darwin Initiative from 2006. Those expeditions made over 7,500 plant and 17,000 beetle collections and described 12 plant species new to science.
