The Bahamas are known around the globe for blue holes (or sink holes), and tour provider Calabash Eco Adventures offers several packages for exploring these natural wonders. During the six-hour, inland blue hole sightseeing tour, travelers visit Lucayan National Park and Ben's Cave, a famous attraction for divers (the company also offers dive packages here). Visitors can climb down the ladder into Owl's Cave for snorkeling, or opt for the intro to diving experience. The trip also stops at Freetown Beach and Banana Bay beach restaurant for tropical cocktails and seafood snacks after a long - but eventful - afternoon.
