Beinn a' Mhanaich
Beinn a' Mhanaich (709m) — the monk's hill — sits at NS26 in the Luss range above Glen Fruin, just north of Beinn Chaorach and east of Loch Long. A grass-and-bilberry cap with a small cairn gives views east over Loch Lomond to Ben Lomond, west to the Cobbler and Beinn Narnain, and south over the Faslane base to the Firth of Clyde. The hill takes its name from an old chapel-of-ease that once stood at the foot of its slopes.

From Glen Fruin parking at NS275935, take the metalled estate track climbing north-east into the headwater corrie. Strike up the south-west ridge on sheep paths and short grass to the summit. 13km return for an out-and-back; 581m of climb concentrated in the upper half. The hill makes a natural pairing with Beinn Chaorach for a half-day Luss circuit.
Terrain
Cropped Luss-style turf above 350m gives quick walking. A few peat hags surface on the broad ridge — easily avoided. The summit cairn rests on grassy ground; a small rocky outcrop just below offers shelter from west wind. Lower ground in Glen Fruin can be wet, but estate drainage helps.
In winter
High Loch Long rainfall and frequent freezing-fog episodes coat the bilberry slopes in verglas through any cold snap. Snow lies briefly but rarely deep. The Luss Hills sit outside any formal SAIS region — judgement and patience replace forecast. Daylight here is around eight hours in midwinter — better than central or northern hills.
This hill is in the Southern Highlands SAIS forecast area. Check SAIS forecasts in winter (December–April).
