Wilderness Landscape & Natural Heritage

Mu Ko Ranong National Park, established in 1991, spans a group of more than 40 islands in the Andaman Sea off the coast of Ranong Province, Thailand. The park covers both terrestrial and marine environments, featuring rugged limestone cliffs, dense tropical rainforests, mangrove swamps, and clear waters rich in coral reefs. Its geography primarily consists of limestone islands with caves, natural bridges, and hidden lagoons accessible by boat. The park is home to diverse flora and fauna including rare hornbills, monitor lizards, macaques, and various marine species such as tropical fish, sea turtles, and occasional dolphins. The park is also known for its hot springs on the mainland nearby, offering a unique combination of forest and coastal experiences. Activities include island hopping, snorkeling and diving around coral reefs, kayaking, birdwatching, and hiking through forest trails. Key landmarks include the limestone caves like Tham Le Khao Kam, pristine beaches on Ko Phayam, and the panoramic viewpoints atop some islands. Visitors enjoy the mix of tranquil beach settings and rich underwater life, making it a favored destination for ecotourism and adventure. The park promotes conservation of its marine biodiversity and forest habitats, with several areas designated as protected zones. Access is primarily by boat through Ranong town or the small islet communities. Facilities are rustic in many islands, ensuring a natural, low-impact visitor experience.
