Caves in Laos
Explore Laos’ underground landscape in one of its countless caves. Creep around limestone cavities, boat through mountain tunnels, and visit “Cave City”.

 

When it comes to caves, Laos is king. Subterranean experiences range from squeezing through crevices to entering spacious grottoes with ancient Buddha images. Cavers of all levels can spend hours examining bizarre rock formations and natural pools in well-mapped cave systems. Boat along underground rivers, sneak around rarely visited crevices, and follow stone paths lit by the sun peeking through roof cracks.   

Northern Laos is loaded with caves. The recently opened 6-hour trek through Oudomxay’s Chom Ong Cave is drawing a crowd, and you can be among the first to explore the 1,000 Caves Area in Sayabouly. Luang Prabang’s Pak Ou Caves remains on everyone’s bucket list, and the endless Kao Rao cave system in Luang Namtha deserves a peek. And don’t miss Houaphanh’s “Cave City”, home of the Lao revolution.

Most caves in Central Laos are drilled into Khammouane’s limestone landscape. Choose from the 7.5-km cruise through Konglor Cave, Cave Alley’s six grottoes on a 20-km strip just outside Thakaek, or little-known Xebangfai Cave on the Ho Chi Minh Trail that attracted National Geographic. Vang Vieng is also gaining a reputation among underground adventure hounds, as 15 caves, many in clusters, are within a bike ride from town.

Cave hunters visiting Southern Laos can take a short trip from Pakse to Salavan, where underground experiences continue to be discovered. Caves ready to explore carry catchy names that describe what you’ll find, like Stone Casket Cave and 9-Holes Cave.
