Two Sisters Cave connects with many other caves and tunnels in the Hellshire Hills, St. Catherine. The cave beneath is connected with many other caves and tunnels. Each cave has a large sinkhole with fresh water. It is believed that these reservoirs were fresh water supplies for the Tainos who inhabited the island centuries ago.
