This limestone cavern, complete with stalactites, stalagmites, subterranean streams, and a 40-foot waterfall, is a rare find in the Caribbean—and one of Barbados's most popular attractions. Tours include a nine-minute video presentation and an hour-long underground journey through the cavern via electric tram. The visitor center has interactive displays, life-size models and sculptures, a souvenir shop, restaurant facilities, and elevator access to the tram for people
with disabilities. Tours fill up fast, so book a reservation.
