About Hen Mountain

Hen Mountain provides accessible granite climbing on scattered Tor-like outcrops perched across the Western Mournes near Hilltown. The rock character features coarse, high-friction granite with rounded top-outs, crisp horizontal hand-breaks, and clean vertical crack systems. Facing multiple directions across its individual tor blocks at moderate mountain elevation, aspect varies, allowing teams to seek out sunshine or shelter as ambient mountain breezes dry the rock steadily after rain. The climbing caters heavily to lower and intermediate traditional leaders, offering well-protected slab, wall, and crack routes from Diff to HVS, with Hen Mountain Crack standing out as a local benchmark. The approach involves a straightforward twenty-minute walk along established hill tracks starting from the Sandbank Road parking area. High altitude wind exposure can make conditions cold, so checking mountain weather forecasts before visiting is essential.
