Guana Island sits off Tortola's northeast coast. Sailors often drop anchor at one of the island's bays for a day of snorkeling and sunning. The island is a designated wildlife sanctuary, and scientists often come here to study its flora and fauna. It's home to a back-to-nature resort that offers few activities other than relaxation. Unless you're a hotel guest or a sailor, there's no easy way to get here.
