Mount Sonder, or Rwetyepme, its Aboriginal name, is the fourth highest mountain in the Northern Territory, Australia at 1,380 metres (4,530 ft) AHD.

It marks one end of the celebrated Larapinta trail, which extends 223 kilometres (139 mi) to Alice Springs.

The shape of the mountain is a double peak, the relative heights of which are somewhat ambiguous from the summit, although easy to identify from the surrounding plains.

Explorer Ernest Giles named the mountain in honour of German botanist Dr. Otto Wilhelm Sonder.

[1] A clearly defined walking track exists up the western side, which is about 12 kilometres (7.5 mi) long.
