Bako is the oldest gazetted national park in Sarawak. It offers the perfect introduction to Sarawak flora and fauna. The 16 square kilometers of primary forests are home to seven distinct ecosystems; beach vegetation, cliff vegetation, mangrove, peat swamp forests, mixed dipterocarp forest, heath forest, and grasslands. Constant erosion over millions of years has turned the Bako coastline into a unique geographical landmark. Cliff faces, sandstone structures, sea stacks, and pristine sandy beaches dot the area.

Wildlife includes the rather intrusive long-tailed macaques which roam all over and their shier cousins, the silver leaf monkeys, and the rare, long-nosed, pot-bellied proboscis monkey. Other denizens include flying lemur, mouse deer, bearded pigs, bats, tarsiers, slow loris and palm civet cats. There are 16 trails, each offering close-up look at different aspects of the Park.
