Kayaking is a good way how to get to know the Ko Lanta island. You can rent a kayak in Mu Ko Lanta national park or in Sang Ga Boat resort which is situated at the southern tip of the island and go along the coast. The mangrove channels are also nice location to go to by kayak, starting from Thung Yae Pheng Village in north Ko Lanta. The kayak costs 200 THB per hour but you get discount in case of whole-day renting.
