Glen Sannox (Arran) offers majestic, high-altitude mountain climbing set amidst the granite peaks of Cir Mhor and Ceum na Caillich on the Isle of Arran. The rock is coarse, granite of magnificent quality, featuring friction slabs, clean corners, and giant horizontal flakes. Facing east and northeast in a wild mountain horseshoe, the upper crags catch morning light but take time to dry after rain due to mountain mist. The climbing encompasses long multi-pitch mountain traditional classics, ranging from friendly VDiffs to technical E-grade granite face climbs, led by Labyrinth. The approach requires a sustained ninety-minute walk up Glen Sannox along built trails from the Sannox village parking area. Rapid mountain weather changes and lengthy descents demand proper mountain preparation.
