Harrison’s Cave

Welchman Hall, St. Thomas, (246) 417-3700. Daily tours 8:45am-3:45pm. US$30, children US$15.

Located in the center of the island, this massive subterranean cavern features streams, waterfalls, cascades, and deep pools. Harrison's Cave is unique in that it is not volcanic in composition but is formed instead from crystallized limestone. Limestone caves are noted for their beautiful formations and also for being among the deepest and longest caves in the world.

Visitors have a choice of two scenic trails or a glass-front elevator to transport them from the cliff-top entrance to the valley floor, where to actual cave entrance is. After viewing an educational film, visitors board an electric tram for a 45-minute tour. Several stops are made to explore a plunging waterfall and a large cavern. Throughout, lights illuminate the impressive interior’s stalactites and stalagmites. Another tour is also available for those who want to crawl and climb and explore more closely.

The Cave Bistro offers a lunch menu, and the Cave Bar serves a particularly colorful rum punch. Green monkeys are also often seen here.
