Mu Ko Lanta National Park is a national park in the southern part of Krabi Province, Thailand, consisting of several islands. The two largest islands are Ko Lanta Noi and Ko Lanta Yai. Although both are inhabited, Ko Lanta Yai is the primary tourist destination. The park was established in 1990. A clan of Chao Ley, or "sea gypsies" lives on Ko Lanta Yai. The clan still practices many of their ancient customs and ceremonies, such as the setting of ceremonial boats adrift to bring good luck and prosperity on the full moon nights of the sixth and eleventh months.
Etymology
Ko Lanta was once known by its Malay name, "Pulao Satak", which means "Long Beach Island". Later, many Thais, both Buddhist and Muslim, moved to the island making the island known as the island of "a million eyes". The name may also be derived from the Javanese "lan-tas", or fish grill.
