Cruach an t-Sidhein
Cruach an t-Sidhein — the fairy hill — is the awkward western outlier of the Luss Grahams, the steep grassy group on the west side of Loch Lomond. It is a shapely hill in its own right, but its position tucked out beyond Doune Hill makes it the trickiest of the Luss tops to reach, which keeps it quiet. The reward is a clean view east over Loch Lomond to Ben Lomond and south down the Firth of Clyde.

Most walkers take Cruach an t-Sidhein as the far point of a Luss Hills round, dropping west off Beinn Lochain to the intervening bealach and climbing the steep grassy east flank to the summit. Approached on its own it is a steep pull from Glen Luss or Glen Mollochan over rough, pathless grass. As an out-and-back outlier expect around 11km and 720m of ascent; allow 4–6 hours depending on how many of the neighbouring Grahams you take in.
Terrain
Predominantly steep grass, with no continuous path and a fair amount of rough, tussocky and boggy ground between the Luss tops. Straightforward going in dry weather but slippery and tiring when wet; the connecting bealachs add ascent on a multi-Graham round.
In winter
Low enough to be snow-free much of the winter, but the steep grass flanks become hard and slick under frost or old snow, when an axe and confidence on grass are worth having. Short daylight and the pathless ground make navigation the main concern in poor visibility.
This hill is in the Southern Highlands SAIS forecast area. Check SAIS forecasts in winter (December–April).
