Taman Negara sprawls across 4343 square kilometres and is Malaysia’s biggest national park and, even more impressive, home to the planet’s oldest rainforest. This primeval jungle has remained relatively undisturbed for upwards of 130 million years, and it provides a habitat for a myriad of wildlife, including wild boars, monkeys, tapirs and a profusion of bird species. Nature lovers and thrill seekers alike will be in their element here, with a wide array of adventure activities that include trekking, caving, fishing, swimming, rafting, rapid shooting and night jungle hikes.
