The 42 karst islets of Ang Thong National Marine Park (Mu Koh Ang Thong) in southern Thailand comprise a picturesque seascape spanning more than 95 square miles (246 square kilometers). These limestone pinnacles harbor secluded powdery beaches, sheer cliffs, and caves, and are home to myriad birds, monkeys, dolphins, and other wildlife.
Ang Thong National Park is a popular destination for Thailand visitors seeking a little adventure and a lot of nature. Tropical and dry evergreen forests of the interior area house oriental pied hornbills, little herons, crab-eating monkeys, and bats. In the shallow waters, sometimes you can find dolphins, whales, and otters. It’s said that the park inspired the backpacker utopia of Alex Garland’s The Beach.
Most travelers experience Ang Thong on single-day guided tours from Koh Samui or Koh Phangan to Wua Talap Island and its famous Emerald Lake. These guided tours are the way to go, and most day trips include lunch, snorkeling gear, park admission fees, and hotel transfers. Tour boats are often multi-story, open-air, 40- to 50-person crafts, but small private speedboats or luxury yachts are also available. If you wanting to see what’s under the surface, opt for snorkeling, sea kayaking, or scuba diving tours.

Sea Gypsies of the Ang Thong Islands
All but one of the 42 Ang Thong Islands are uninhabited. The one with a permanent community, Koh Paluay, is home to a traditional community of sea gypsies who still earn a living through traditional fishing methods.
