Serious divers are attracted to such Grand Bahama sites as the Wall, the Caves, Theo's Wreck, and Treasure Reef. Other sites frequented by UNEXSO include Spit City, Ben Blue Hole, and the Rose Garden. Keep in mind that UNEXSO's specialty is diving, while Paradise Watersports primarily entertains snorkelers.

Paradise Watersports, located at the Xanadu Beach Resort & Marina (tel. 242/352-2887), offers a variety of activities. On the snorkeling trips, you cruise to a coral reef on a 14m (48-ft.) catamaran, "Lady Paradise." The cost is $30 per person. Kayaks rent for $8 for a half hour, $12 per hour, and water-skiing is priced at $20 for a 2.5km (1 1/2-mile) ride. Parasailing costs $50 for a 5-minute ride.

Underwater Explorers Society (UNEXSO) (tel. 888/365-3483 or 242/373-1250) is one of the premier dive outfitters in The Bahamas and the Caribbean. There are seven dive trips daily, including reef trips, shark dives, wreck dives, and night dives. This is also the only facility in the world where divers can dive with dolphins in the open ocean.

A popular 3-hour learn-to-dive course is offered daily. Over UNEXSO's 30-year history, more than 50,000 people have successfully completed this course. For $99, students learn the basics in UNEXSO's training pools. Then, the same day, they dive the beautiful shallow reef with their instructor.
