Massive subterranean chambers and crystal cavern formations in South America
South America's cave systems range from the vast limestone karst networks of the tropical interior and the quartzite cave systems of the ancient highland plateaus to the lava tubes of the volcanic island chains and the underwater cave systems of the Caribbean and Pacific coasts. The continent contains cave environments of extraordinary geological significance, with prehistoric rock art, exceptional formations and endemic cave fauna distributed across systems that remain among the least explored of any major cave region.
The continent's most significant cave destinations combine exceptional geological formations with archaeological and ecological significance, with several systems containing prehistoric human remains and rock art that add cultural depth to the geological experience. Adventure caving infrastructure is developing across the most accessible destinations, with guided programmes and show cave facilities of increasing quality supporting visitor access beyond the specialist caving community.
Safety standards and guide qualifications vary considerably and researching operator credentials before booking undeveloped cave experiences is essential. Seasonal flooding affects access at many tropical cave systems and checking current conditions before travel is non-negotiable. Your money goes a long way making extended cave itineraries practical even when specialist guiding adds to overall costs.

Guanacos are the most prominent animals in the paintings, often in hunting scenes. The cave is in the Pinturas River Canyon and became a World Heritage Site in 1999.

Vibrant diversity meets natural wonder
Fossil bones of giant sloths and armadillos have been found in Gruta do Lago Azul. The cave near Bonito was named a natural monument in 1978. A round opening about 40 metres wide lets sunlight onto a lake more than 50 metres long. The light turns the water an intense blue.

Land of diverse natural wonders
Caverna de las Brujas is a limestone cave in the Andes of Mendoza Province. Visitors get helmets and lamps because the cave has no electric lighting. Guided tours last 30 or 90 minutes and groups have at most 10 people. The cave is 6 kilometres long and was shaped partly by oil pools.

Compact country, immense biodiversity
On the eastern slopes of the Andes, Cueva de los Tayos lies in high rainforest. Its name means Cave of the Oilbirds, after the night birds inside. The cave is 4.6 kilometres long, the longest in this country. A 1976 expedition included Neil Armstrong. Visits need permission arranged through the Shuar federation.
