Mu Ko Lanta National Park occupies the southern tip of Ko Lanta Yai in Krabi Province, encompassing both terrestrial rainforest and surrounding marine areas. The park features two primary white-sand beaches, Tanod Bay and Kantiang Bay, separated by a rocky headland. A historic lighthouse sits atop the headland, serving as a prominent landmark and viewpoint. The protected area covers a total of 134 square kilometers including several smaller islands like Ko Ngai and Ko Rok. It is a designated marine sanctuary known for its coral reefs and diverse tropical marine life. Terrestrial inhabitants include macaques and various lizard species often found near the park entrance.
