Taman Negara was established in Malaysia in 1938/1939 as the King George V National Park. It was renamed to Taman Negara after independence, which literally means "national park" in Malay. Taman Negara has a reputation as the World's oldest tropical rainforest.
Taman Negara encompasses three states, Pahang, Kelantan and Terengganu, each with its own legislation. The Taman Negara Enactment (Pahang) No. 2 of 1939 is enforced in the state of Pahang, the Taman Negara Enactment (Kelantan) No. 14 of 1938 in the state of Kelantan and the Taman Negara Enactment (Terengganu) No. 6 of 1939 in the state of Terengganu. The enactments have similar contents.
The park has been developed into a famous ecotourism destination in Malaysia. There are several geological and biological attractions in the park. Gunung Tahan is the highest point of the Malay Peninsula; climbers can use Kuala Tahan or Merapoh as their departure point. Taman Negara is the home of some rare mammals, such as the Malayan Tiger, Crab-eating macaque, Sumatran Rhinoceros, Great Argus, Red Junglefowl, Malayan Gaur (seladang) and Asian Elephant. Among the birdlife, the rare Malayan Peacock-pheasant is still found here in some numbers. Tahan River has been preserved to protect the Malaysian mahseer (ikan kelah in Malay), a type of game fish.
