Krau Wildlife Reserve, Wildlife reserve in Pahang, Malaysia.

Krau Wildlife Reserve, now officially Tengku Hassanal Wildlife Reserve, covers 605.52 km2 of the Titiwangsa Mountains in central Pahang, from Kuala Lompat at 43 m up to Gunung Benom at 2,107 m. About 61% of its forest is lowland dipterocarp, with hill dipterocarp and montane forest above. Its offices sit at Bukit Rengit, Lembah Krau, Kuala Lompat and Perlok.

The reserve was created in 1923 to protect endangered animal species, particularly local gaur populations. This early conservation effort established the area as a key project for regional wildlife protection.

The reserve contains research stations at Kuala Lompat dedicated to studying primates, bats, and birds native to Malaysian ecosystems.

The area can be accessed through several entry points including Kuala Lompat, Bukit Rengit, and Kuala Gandah, each offering different exploration routes. Visitors should expect varying weather conditions and prepare appropriately for hiking through different elevations.

The reserve's name changed in November 2022, when Krau Wildlife Reserve became Tengku Hassanal Wildlife Reserve, honouring the crown prince of Pahang as its protector. The reserve was first gazetted in June 1923 as Krau Game Reserve, after public concern over wildlife loss as forest was cleared for rubber.
