The beach is guarded at both ends to allow only Sandals guests and adjacent hotel guests onto the beach. We did plenty of sailing. They have Sunfish, Hobie Waves, Hobie Cat 16 s, and sailboards for wind surfing. You may take a sailing lesson there also. You may water ski first thing in the morning when the water is very calm.
Snorkeling is good.
The reefs are very nice but the fish are small compared to Hawaii. They take you to four different reefs. You spend about hour snorkeling on each excursion. If you like snorkeling, follow the guide around when you jump off the boat. He will take you on a tour of the reef pointing out the various forms of aquatic life.
