The Arfak Mountains is a mountain range found on the Bird's Head Peninsula in the Province of West Papua, Indonesia. The term "Arfak" came the language of the coastal Biak people, meaning "inferior." This is due to how big the mountains are compared to other lowland areas found in this region. Located in the east and central regions of the Bird's Head Peninsula, these mountains rise steeply from the sea, wiht little or no coastal plain that surround them. Pegunungan Arfak, at 2,955 m (9,695 ft), can be viewed from the provincial capital, Manokwari and is the highest point in West Papua and the Bird's Head Peninsula. Since the Dutch colonial times, the range has been one of the most frequently explored and best known regions of West Papua for bird watching. Along with the Tamrau Mountains in the north, the two ranges have been divided by the grassy Kebar Valley, which is the heartland of many indigenous people, with a variety of backgrounds. Found near the town of Manokwari, the mountains are an important and threatened site of biodiversity, part of the Vogelkop Montane Rain Forests Ecoregion.
