Located in Pahang, this is the oldest tropical rainforest in the world. As old as 130 million years. This gorgeous, verdant rainforest is one of the most amazing places to see in Malaysia. It’s easy to feel small and insignificant in the face of such magnificence. There are humongous trees here, along with some delightful waterfalls and jungle treks along with the world’s longest canopy walkway. Several endangered animal species such as tigers, leopards and rhinos live here but sighting them is not too likely. This is certainly one of the top Malaysia sightseeing spots that you should not miss.
