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 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. The largest island (Ko Lanta Yai) has nine white sandy beaches running down the entire west coast, forests, and ancient tropical jungle. The geography of the island is typically mangroves; coral rimmed beaches; and tree-covered hills. A popular tourist destination, the islands are known for their long, sandy beaches and scuba diving.[1]
