Costa Rica isn’t well known for its caves, but boy does it have some great ones, and they’re all in Barra Honda National Park. Although just one of the 42 known caves is accessible to the public, the area is an ideal stopping point if you’re driving from San José to Guanacaste. Beneath a majestic dry forest, the deep limestone cavern features stalactites and stalagmites. Around the caves, cacti are everywhere. Monkeys and bats, too. It’s weird, man.
