Red Cuillin - Glamaig and Marsco

Hiking routes on the Corbetts in the Red Cuillin of Skye

The granite covered Red Cuillin peaks tower above the inlets of Loch Sligachan and Loch Ainort. The views from the summits are wonderful, particularly across to Skye's Black Cuillin.

Main route summary

Terrain on the Red Cuillin mountains can be quite challenging for most hillwalkers - the scree (particularly on Glamaig and Beinn Dearg Mhor, but less-so on Marsco) not only makes for demanding ascents, but also tricky uphill route finding. Paths are also somewhat scarce and faint.

If you've got hardy ankles the scree also allows for fast running descents, putting a smile back on faces after the slog uphill. Check out the incredibly tough and popular Glamaig Hill Race - a direct ascent and return from the Sligachan Inn.
