The park contains many notable geological features, such as the
Barva Volcano; and several dormant volcanoes including Cerro Chompipe, Cerro Cacho Negro, and Cerros las Tres Marias. The Barva sector has three
crater lakes — Barva, Danta, and Copey. The park also protects areas of the
Sarapiquí River watershed, including large amounts of primary cloud and rainforest, and the flora and fauna that makes it their home. Others in the park include the Hondura River, Patria River, and the mineral-colored
Súcio River.
Biodiversity Both the large size (108,970 acres) of Braulio Carrillo National Park, and its varied altitude of between the highest and lowest points, make it home to several
WWF ecoregions. Ranging from high-altitude
cloud forests to lowlands
tropical rainforest, it has one of the highest levels of
biodiversity in Costa Rica. More than 90% of the park is covered in
primary forest. The park contains landscapes representing the WWF ecoregions of
Talamancan montane forests at high elevations and the
Isthmian–Atlantic moist forests at low elevations. It is significant for its biodiversity with 600 identified species of trees, over 530 species of birds, and 135 species of mammals catalogued. The area near Barva is home to the elusive
frog Pristimantis altae, and the venomous snake
bushmaster. Examples of birds found include the
solitary eagle, the
bare-necked umbrellabird, as well as several species of
hummingbirds. ==Recreation==
