The district, approximately 70 km from Krabi Town, consists of three major islands. The first, Ko Klang, is separated from the mainland by a small river (klong) and road bridge, and is often mistakenly thought of as part of the mainland Krabi Province. Of the two remaining larger islands, the largest, more populated Ko Lanta Yai (commonly known as simply Ko Lanta) and the smaller Ko Lanta Noi, together with 50 other smaller islands make up the 52-island Mu Ko Lanta National Park.
