Main image

An Caisteal is a mountain in the Crianlarich hills of the Scottish Highlands and is classified as a Munro, with a summit elevation of 995 metres. The name is Gaelic for “The Castle”.

The mountain is frequented by hillwalkers and is noted for its rocky summit ridge and steep sections on common ascent routes. It forms part of a group of peaks often climbed together by walkers in the central Highlands.

The name reflects the summit’s castellated rock shapes seen from some approaches; the hill has long been part of local hillwalking traditions rather than having a built history. Routes are straightforward hillwalks in summer but can involve exposed ground and scrambling on some sections.

An Caisteal sits in the southern part of the Scottish Highlands near the village and transport hub of Crianlarich and is within the wider mountain terrain of central Scotland.

  • Elevation: Summit elevation is 995 metres, classifying it as one of Scotland's Munros.
  • Name meaning: The Gaelic name means "The Castle", referring to the mountain's steep rocky summit features.
