Towards the north and northwest of Tasik Temenggor lies a vast area of virgin jungle known as Royal Belum State Park. This pristine forest is excellent for trekking, bird watching and animal sightings. It was out of bounds to visitors until recently, but permission has to be sought to enter the forest as it is still a security area.

Nevertheless, Royal Belum State Park is of great interest to ecologists, conservationalists and nature enthusiasts. Covering an area of 134,167ha, several expeditions including one by Malaysian Nature Society in 1993, found the place to contain new and unknown species of tress and insects.

Visitors who  gain entry into this forest will agree that this is one of the best places natural destinations.
