About 53 islands are included in this group, which form the southern most district of Krabi Province.
Koh Lanta Yai ,the largest of the islands and long beach. The island is a favourite spot for those seeking peace and solitude, and is the home of the District and National Park offices. Mountainous and rugged in some spots, especially near the southern tip; with a combination of gravely and fine white sandy beaches, the island is also home to a clan of Chao Ley, or Sea Gypsies - an ethnic group who preserve many of their ancient customs and ceremonies. In recent years accommodation has increased in Lanta with a range from basic bungalows to upmarket resorts now available.

Koh Taleng Beng ,lies in the Lanta district and is similar in shape to Phi Phi Ley. Swallows also nest at this island which at low tide has a small beach and tunnel.

Mu Koh Hah ,still in the Lanta area, this is a group of 5 islands featuring coral gardens and good diving spots.

Koh Ngai, Koh Rock Nai and Koh Rock Nok

South of Lanta Island, these 3 islands are close to Trang Province. Koh Ngai is easily accessed via ferry from Pak Meng Beach, others are accessed by hired boat and feature both beaches and coral gardens.
