Chirripó National Park is located in the middle portion of the Talamanca Range of Costa Rica, approximately 30 km northeast from the city of San Isidro del General. It protects a number of important ecosystems on the Costa Rican Pacific slope and is notable for including the largest extension of páramo vegetation in the country. Because of these conditions, the Chirripó National Park preserves a number of plants, animals, fungi and insects, some of which are under study by the scientific community. It is named for Cerro Chirripó, at 3820m (12,538 ft), the highest mountain in Costa Rica.
With a particular climate that includes only two seasons, a dry one approximately from December to April and a wet one from May to November, this national park is among the most exciting ones for locals and tourists from around the World. This is based on the fact that in order to get to the summit (Cerro Chirripó) the visitor has to walk along a 16 km uphill trail from the town of San Gerardo de Rivas to the park ranger's refuge in the Los Crestones sector and save energies for the next 5 km walk from here to the peak. Considering that Chirripó is the 38th most prominent peak in the world, this journey is a once in lifetime experience for most tourists.
This national park encompasses parts of three Provinces in Costa Rica - San Jose, Limón and Cartago, and contains five different ecosystems according to the Holdridge life zone classification system , being these: lowland tropical wet forest, premontane tropical wet forest, lower montane wet forest, montane wet forest and subalpine wet forest (paramo).
