A breathtaking jewel of nature, Harrison's Cave is the best exhibit of stalactites and stalagmites on the island, where creeks of clear water from waterfalls form pools. In some cases, the stalactites are reaching down to the stalagmites, forming a gorgeous pillar. The cave is more than 2 kilometers long, and much of it is open for tourists. Visitors love to take an electric trams tour, but eco-tour is also available.
