Harrison's Cave is a natural wonder located in the parish of Saint Thomas in central Barbados. It is a limestone cave system that was formed over thousands of years by water erosion, and was first documented in the late 18th century.

The cave features stunning stalactites, stalagmites, waterfalls, and deep pools of crystal-clear water. Visitors can explore the cave on a tram ride that takes them through the various chambers, or on a walking tour that allows them to get up close and personal with the formations.

The tram ride takes visitors through the larger chambers of the cave, with informative commentary from guides. The walking tour takes visitors through the narrow passages and smaller chambers of the cave, where they can see the formations up close and learn about the geology and history of the cave.

Harrison's Cave also features a museum and gift shop, where visitors can learn more about the natural history and culture of Barbados. The cave is a popular tourist attraction in Barbados and is considered one of the island's must-see destinations.
