Cueva de los Guácharos National Park (English: Cave of the Oilbirds) is the oldest national park in Colombia. Located in the western face of the Colombian Eastern Andean Range in the departments of Huila and Caquetá.

When you visit Cave of the Oilbirds National Natural Park, you must remember that you are entering an area of such great importance for eco-tourism and for its flora and fauna that it was declared a Biosphere Reserve by UNESCO in 1979. You must therefore refrain from touching the calcareous formations in the Park’s and/or from defacing natural elements of the landscape. Just relax and respectfully enjoy this unique environment so that we may hand its riches down to future generations.


The relief is rugged, represented by canyons, hills, caves, escarpments, gently sloping mountains and eroded valleys. Some of the rock formations are over 100 million years old and correspond to seabed sediments in the cave sector and to volcanic rock in the north-eastern part.

There are four small wetlands, of less than one hectare: one on the left bank of the Suaza River opposite El Lapiaz, also known as La Cascada; the second on the right side of the Cascajosa-Cedros trail, at the place called La Hacienda; the third in the north of the Park on the road that passes through Acevedo; and the fourth in the centre-south sector of La Argelia. However, the Park is characterised by four main ecosystems: the oak forest, the Sub-Andean forest, the Andean forest and the paramo.

Suaza River - The Guacharos Cave National Natural Park


The Park´s hydrographical network comprises two large basins; tha of El Magdalena, represented by the Suaza River, which rises on the westerm slope of the Cordillera Oriental, and that of El Caqueta, which is constituted mainly by the Cano Agachado and the Quebrada La Fraguosa, the sources of the Fragua Grande River.


The Park area is noteworthy for the presence of a substantial number of specimens of species practically on the verge of extinction in their natural environments, such as the cedar, the cumin, The cobre, the laurel, the Colombian walnut, the walnut, the white oak and the black oak, this latter first reported in the Park in 1979, on the site known as El Robledal, on the Cascajosa-Cedros trail.

Araña Pocok - The Guacharos Cave National Natural Park


The most prominent species is the one from which this national natural park takes its name: the guacharo or oilbird (Steatomis caripensis). It was discovered in 1799 by the German traveller and naturalist Alexander von Humboldt in Caripe (Venezuela). It is a bird that inhabits deep, dark caves during the day, because its habits are nocturnal. It comes out at night to search for food, guided by an echolocation system similar to that of bats, which allows it to find its way around in the darkness. Thanks to the tactile bristles, near the bill, it feeds on the fruit of over 70 species of laurels and palms. Its body is reddish brown with bronze and copper tones and white patches. It measures up to 50 centimetres, although it has a wingspan of one metre. Besides the oilbird, the Park area is home to some 300 species of birds, among them the cock-of-the-rock and the yellow-eared parrot.

Another noteworthy aspect of the Park fauna is the fact that it includes several endemic species on the verge of extinction, like the most primitive weasel hitherto discovered, the great tinamou (the largest of it kind in Colombia) and the marsupial frog. Lastly, there are over 60 species of mammals, among them the spectacled bear, the puma, the northern pudu and five species of primates; and 50 species of butterfly.


There has been no human population in the Park since 1980, when the State acquired the estates bequeathed by the last 13 colonists who had settled in the area. In the XIX century, after the War of Independence, the south-east sector of Huila Department, where the Park is located, began to be settled by indigenous peoples from northern Narifio and southern Cauca. At the beginning of the 1940s, people from northern Boyaca and southern Toli-ma populated the banks of the Quebrada La Cascajosa and the River Suaza, which are now contained in the Park area.
