Surin Island is in Mu Koh Surin National Park, found some 60 km off the west coast of Phang Nga province, and 100 km north of the Similans, is an archipelago of 5 islands: Koh Surin Nuea, Koh Surin Tai, Koh Ri, Koh Khai, and Koh Klang. The excellent diving, snorkelling, hiking and game fishing are what most visitors come for, and those hoping to find a quiet refuge from the tourist traps and urban centres will be delighted with the islands' lack of "development". Those seeking convenience, comfort and 5-star service had best choose another destination - or travel there on a luxury liveaboard cruise. The main island of Surin Nuea has several bays, the largest being Ao Mae Yai on the southwest, which features calm waters and safe anchorage. On the southeast side is Ao Luek, which has shallow corals and an abundance of marine life. Ao Mai Ngam is where the National Park's office is found, as well as a 2-kilometre walking path. There's good snorkelling and swimming here off its long beach. Ao Chak at the north of Surin Nuea is a beautiful bay of pristine coral reefs.
