Endau-Rompin National Park, Johor

The second-largest national park in Peninsular Malaysia, Endau-Rompin preserves a crucial block of lowland rainforest that represents the last viable habitat for the critically endangered Malayan tiger on the Johor-Pahang border. Multi-day river and jungle trekking expeditions into the park's interior waterfalls and prehistoric plants are among Malaysia's most rewarding wilderness adventures.
