Hop on a 30-foot bamboo raft and float down a 3-mile stretch of the Martha Brae River. This is kind of like a gondola ride in nature without the singing, and ends at Miss Martha's Herb Garden, which features Jamaican medicinal herbs, souvenirs, and food. The gondola ride is 1 hr. 15 min.
Jamaica is known for its rums and Appleton is the reason why. Instead of having one rum cocktail, take a tour and have six rum cocktails and call it a "tasting." It's much classier. Walk-ins are welcome, but reservations are recommended for groups of 15 or more. The drinking age in Jamaica is 18.
Ask for Captain Polly and tell him that Kevin Henry sent you.
