Caving: Cueva del Indio & Cueva de la Vaca

Cueva del Indio is in Páramo. Operators describe a tour of about two hours: you go in one way and come out another, past bats and stalactites, and finish with a "salto de fe" — a jump in the dark into a deep pool. It is optional. Sources disagree on the jump height (from about 3 m to about 10 m), so take the guide's word on the day.

Cueva de la Vaca, near Curití, is the one colombia.travel calls the biggest and most thrilling. It's wet the whole way, with big galleries and small passages where you crawl or duck underwater for a moment — one operator mentions an 11-metre flooded tunnel. You go in and out by the same entrance.

Quick comparison: Indio is the better first cave, with more walking, more wading and less squeezing, plus that optional jump at the end. Vaca is for people who are fine with tight, wet, dark spaces and want the harder story to tell. If small spaces make your chest tight, skip Vaca and do Indio. Either way, expect to come out muddy.
