Alternatively, you can take a 45-minute trip by longtail boat to circular Bamboo Island, with a superb beach around it. The underwater colors of the fish and the coral are brilliant. The island is uninhabited, but you can spend a night under the stars if you're adventuresome. You can also hike up to a series of viewpoints toward the 1,030-foot peak on the east side of the island. The trailhead is near Tonsai Bay; ask your hotel for directions.
