Malaysia's oldest, largest and most popular national park straddles the borders of Pahang, Kelantan and Terengganu in an area spanning a colossal 4,343 sq km: welcome to Malaysia's greatest swathe of continuous lowland dipterocarp rainforest. Since 1939, Taman Negara (which means national park in Bahasa Malaysia) has been a haven for an astonishing range of tropical flora and a vast variety of wildlife, including elephants, tigers, leopards, tapirs and flying squirrels.
Join a tour or hire a guide – and head well away from the park headquarters at Kuala Tahan – to stand even a slim chance of spotting such large fauna. Or set aside nine days to scale the peninsula's highest peak, 2186m Gunung Tahan. Even if you can only spend a day or two here, it's still a great place to experience, on foot or by river boat, and will give you a flavour of how most of Malaysia once looked.
