The park is located within the greater Kenaboi Forest Reserve which lies at the south end of the Titiwangsa Range, Peninsular Malaysia’s granite mountain range. With 9,036 ha of tropical evergreen rain forest, the park includes pristine lowland dipterocarp and bamboo forests at low elevation with seraya ridges and hill dipterocarp forests at the higher elevation (
In 2010, a scientific expedition to Gunung Besar Hantu was carried out to document the biodiversity at high elevation about 1,400 m. Seven years later in 2017, another expedition called the Lembah Jemaloi Scientific Expedition covered the remaining areas at lower elevations, especially the valley at Lembah Jemaloi. During the expeditions, two unknown species of
