Costa Rica is a small country 51,100 km2; separated by four cordilleras ( Guanacaste, Tilarán, Central, and Talamanca). These mountain include the highest peak in central america and sevaral active volcanoes.
the pacific slope can be divided into two climate regions: The dry northen region and the very wet Osa peninsula and lowlands in the south.
Very important to remember that this paradise has what we called rainy and dry season, cause the seasons are defined by variation in rainfall and not by temperature differences.
In this small but biodiverse country more than 200 species of amphibias have been found: Anura: 148 species, 29% endemic. Caudata: 54 species, 65% endemic. Gymnophyona: 8 species.
Osa Peninsula named by National Geographic as "the most biologically intense place on earth", it is a true treasure of land, water, and life.
once an island floating in the pacific, Osa evolved in isolation until it merged with mainland Costa Rica.
the Peninsula is estimated to house 2.5% of the biodiversity of the entire world.
other part of Osa that is really amazing is Golfo dulce where is found one of only four tropical fjords on the planet.
