The Belum-Temengor Forest comprises the Royal Belum State Park, Temengor and Grik forest reserves. Situated in the Grik district, its lowland and hill forests are sanctuaries for a rich variety of wildlife and birds. The Temengor Dam, which was built in 1978, is among the scenic attractions of the area.

Approximately 304 bird species have been discovered with the entire ten Malaysian hornbill species found here. Between July and November, usually during the fruit season, hundreds of hornbills can be spotted around the Temengor Lake in the mornings and evenings. This is the only known area where thousands of hornbills have been seen at any one time or season.

Much sought after birds here include the Plain-pouched, Helmeted, White-crowned and Great Hornbills, Wallace’s and Blyth’s Hawk Eagle, Large Green Pigeon and the Puff-throated Babbler. Between September and November, bird watchers might find the very rare Amur Falcon during the raptor migration period. The main bird watching areas are Pos Chiong, Halong River and the road leading to the Temengor Dam. Bird watching is also possible while cruising around the lake and along various river tributaries. Alternatively, you can bird watch along the forest-lined road of the East-West Highway from Grik to Jeli (Kelantan), which runs through part of the Belum Forest.

Various tour operators offer guided tours to Royal Belum and Temengor forest and will arrange for the necessary permits, river and road transport as well as accommodation, which includes camping. Permission to enter the Royal Belum State Park is required and can be obtained from the Perak State Parks Corporation. This can be arranged by tour operators or guides.
