Cruach Ardrain

Cruach Ardrain is a 1046 meter summit with three distinct ridges forming a Y-shaped structure and marked by a prominent stone cairn at the peak. The three ridges create different routes to the top and give the mountain an interesting shape visible from various viewpoints.

The mountain gained importance in 1892 when William W. Naismith developed his time estimation formula here while walking, which became widely used in mountaineering. This calculation still helps hikers worldwide plan their routes today.

The mountain's name comes from Gaelic words, reflecting how Scottish Highlands features have been named for centuries. You can see this heritage in local place names and signage throughout the region.

Multiple marked trails lead from nearby Crianlarich village to the summit, with the northern route offering the most direct path through established ways. The paths are usually well-used, so good footwear is important, especially in wet or rough conditions.

The mountain contains a gully called Y Gully that changes dramatically with the seasons. In summer it is a moderate scrambling passage, but in winter it becomes a challenging ice climbing route.
