Mu Ko Chang National Park comprises 52 islands in the Trat Province, with Koh Chang being the largest island in the archipelago. Over 80% of the park's land area is covered by tropical rainforest, characterized by steep, rugged mountain ranges and dense jungle interiors. The park supports diverse marine life, including coral reefs, sea turtles, and various tropical fish species. Visitors can access several inland waterfalls, most notably Klong Plu, which is the park's most accessible cascade. The park offers designated hiking trails that navigate through secondary forests and lead to mountain viewpoints. Coastal areas feature mangrove forests and protected bays suitable for sea kayaking. Accommodation is available within the park boundaries through government-run bungalows and camping facilities. The marine zones are part of the protected park area, restricting commercial fishing to preserve biodiversity.
