Pha Nga Bay has several karst islands that can be explored by longtail boat, including the sheer cliffs of James Bond Island, featured in "The Man With the Golden Gun." Some islands are shaped like doughnuts with shallow calm water inside, only reachable at low tide. Popular Phi Phi (pronounced "pee-pee") Island was featured in the movie "The Beach."
The waters surrounding Phuket have great snorkeling and scuba diving, thanks to the bay's warm, clean waters and lively marine ecosystems. Snorkel off the beach at Ao Sane, next to Nai Harn Beach, at Kata Noi or near Patong at Paradise Beach. Drift past anemones, parrot fish and various types of coral.
