Once used to trap goats, this cave is one of the oldest in Bonaire; there's even a tunnel that looks intriguingly spooky. It's the first sight along the northern route; watch closely for a yellow marker on your left before you reach the towering Radio Nederland antennas. Pull off across from the entrance to the Bonaire Caribbean Club, and you can discover some stone steps that lead down into a cave full of stalactites and vegetation. It's best to hire a local guide to traverse any cave in Bonaire. Hans from Outdoor Bonaire is an expert in caving in Bonaire.
