Weyland Mountains

The Weyland Mountains, also known as the Kobowre Mountains, are a mountain range in Western New Guinea. The Weyland Mountains are the westernmost mountains in New Guinea's Central Range, which extends eastwards to the island's southeastern tip.

The Weyland Mountains include several high peaks reaching up to 3891 metres elevation. They are surrounded by lower-elevation areas. To the west, a low pass only 160 metres in elevation separates the Weylands from the highlands of the Bird's Neck Isthmus and New Guinea's western peninsulas. On the north and south, they descend to New Guinea's northern and southern lowlands. To the east, a valley containing the Paniai Lakes, Paniai, Tigi, and Tage, also known as the Wissel Lakes, separates the Weyland Mountains from the Snow Mountains, or Sudirman Mountains, further east.

The Weyland Mountains Nature Reserve, also known as Pegunungan Wayland Nature Reserve, protects the central portion of the range. It has an area of 2230.0 km2. Enarotali Nature Reserve covers the eastern end of the range.
