An Ruadh-stac

An Ruadh-stac rises 892 meters and features three steep ridges arranged in a triangular pattern, with a north face revealing layered geological formations. The mountain's quartzite composition creates the distinctive pale coloring visible across its slopes.

The mountain's structure was shaped during glacial periods when ice carved and polished its ridges into their distinctive form. Glacial debris and ice-polished slabs on the southeastern slopes remain visible evidence of these ancient processes.

The Gaelic name means 'the red stack', though the mountain's quartzite composition creates a distinctive pale grey tone that dominates its appearance. This contrast between name and color makes it a memorable landmark in the local landscape.

Most climbers access the summit via the northeastern ridge, beginning from the A890 road near Coulags in Glen Carron. The ascent requires solid scrambling skills and care on steep exposed sections.

Four small lochs sit at different elevations around the mountain, creating a network of alpine water features. Loch a' Mhadaidh Ruadh stands out as one of Scotland's most beautiful mountain lakes according to those who visit.
