Cave Tour Adventure

The caves are on private land and kept locked, so this is one of the few things on the island you genuinely cannot do on your own.

There are two parts. The dry cave is a walk and a scramble past stalactites that took tens of thousands of years to form, with bats overhead. The wet cave ends in a freshwater pool clear enough to snorkel in, lit from the entrance. Between them there is climbing, some of it on hands and knees, and you will get muddy.

It runs around three hours and costs from about seventy-five dollars. You need reasonable mobility and closed shoes with grip; bring a swimsuit and a towel. Weather does not matter here, which makes this the obvious thing to do on the one grey day of your trip. Book ahead — groups are small.
