The Oilbirds, or Guácharos
For reference, Oilbirds (Steatornis caripensis) are birds that spend all day in the depths of the caves and go out at night to hunt food, usually insects, fruits, and aromatic plants. Same as bats, Oilbirds also use a quite precise natural echo localization system. Hence, they make a series of short and squealing sounds that serve as waves that are used for their localization. According to the American Bird Conservancy about the Oilbird:“it is named for the young birds, which are so fat that indigenous people and early settlers once collected and rendered them down to oil for lighting and cooking”.

Discovering the Cueva de Los Guácharos Natural National Park
Cueva de Los Guácharos NNP was named after the Oilbird, which is called Guácharo in Spanish. The Cueva de Los Guácharos NNP was created in 1960 and belongs to the “Biósfera Cinturón Andino”, Andean Belt Reserve declared by UNESCO in 1979.

It totals an area of 90 square kilometers and is located at the western flank of the Cordillera Oriental, between the departments of Huila and Caquetá. Also, the Cave of the Guácharos is very close to the Magdalena River. Lastly, Cueva de Los Guácharos is considered part of “Andean Amazonian” transition ecosystems, having a great role as a water regulator, among other ecosystem services. Due to its unique characteristics, it is a nest and transitory refugee stop for a large number of migratory birds.Weather
Cueva de Los Guácharos Park is between 1200 meters and 3800 meters above sea level and its temperatures vary between 19 °C and 26 °C, with very humid climatic characteristics.How to get to the Cueva de Los Guácharos National Park

The 2026 institutional heritage of Cueva de los Guácharos. The Parque Nacional Natural Cueva de los Guácharos in Huila is Colombia’s FIRST declared national park — established in 1960, predating the country’s much larger Andean and Amazonian parks by decades. The park sits in the Acevedo municipality (Huila) on the eastern flank of the Andes where the Cordillera Oriental descends into the Amazon basin. Its name — Cueva de los Guácharos (“Cave of the Oilbirds”) — refers to its signature feature: an extensive karst cave system inhabited by a colony of Oilbirds (Steatornis caripensis) — Near Threatened cave-nesting frugivores that use echolocation to navigate the caves and forage on tropical fruits at night. The Oilbird colony is one of the most reliable observation opportunities in Colombia for this unusual species (regional range: Colombia, Venezuela, Trinidad, Ecuador, Peru, Guyana — the Oilbird is not endemic to Colombia despite the park’s iconography).
The 2026 access + practical planning. The park’s elevation range is approximately 1,700-2,500 metres — cloud-forest habitat that pairs the subterranean karst cave ecology with rich Andean forest above ground. Access is via Aeropuerto Benito Salas (NVA) in Neiva (~1 hour flight from Bogotá) then a substantial road transfer south to Acevedo — plan a multi-day trip because getting there and back consumes significant time in itself. Best months for cave access are the December-February and June-August dry windows — the wet season makes the underground cave passages hazardous with elevated water levels. Note: this is a specialist destination for travellers who have already visited Colombia’s more mainstream national parks (Tayrona, Los Nevados, Chingaza, El Cocuy). Combine with a Neiva-based extension to La Tatacoa Desert (Colombia’s premier stargazing destination — see Sula’s stargazing guide) for a full Huila itinerary combining subterranean cloud-forest ecology with tropical dry-forest desert astronomy.
