The Semien Mountains (in Amharic ስሜን or Səmen; also spelled Simien and Simen), in northern Ethiopia, north east of Gondar, are part of the Ethiopian Highlands. They are a World Heritage Site and include the Semien Mountains National Park. The mountains consist of plateaux separated by valleys and rising to pinnacles. The tallest peak is Ras Dashen (4,550 m); other notable heights include Mounts Biuat (4,437 m) and Kidis Yared (4,453 m).,/p>
Because of their geological origins the mountains are almost unique, with only South Africa's Drakensberg having been formed in the same manner and thus appearing similar. Notable animals in the mountains include the walia ibex, gelada, and caracal. There are a few Ethiopian wolves.
