Ao Nang is a small resort town and the busiest beach destination in Thailand's Krabi Province . Although development here has gone unchecked and become rather unsightly, the beaches, with their limestone headlands tied together by narrow strips of golden sand, are pretty likable. Boat trips are available to many surrounding islands. One of the most popular getaways is Railay Beach , reachable by a 20-min long-tail boat ride. The most popular activities in Ao Nang, besides lying on the beach, are nearby rock climbing, mangrove tours, and scuba diving. Try Poseidon Dive Center for a reliable outfit.
