Marilyn · Glen Coe & Lochaber
An Sleaghach
A 515m hill on the remote Morvern peninsula with at least 150m of prominence — enough to feel like a real summit rather than a shoulder. The modest height belies the quality of the walking.

Standard route
Standard route
A steady ascent through the dramatic Lochaber landscape with views to surrounding peaks to the 515m summit. The walking is straightforward with clear views opening up as you gain height. Allow 2-4 hours.
Terrain
Rough ground typical of Lochaber — a mix of rock, peat and grass. The terrain is more demanding than the height suggests.
In winter
Lochaber winter conditions are variable — Atlantic weather means rapid freeze-thaw cycles. Check conditions carefully. Snow can fall at any altitude.
This hill is in the Glen Coe SAIS forecast area. Check SAIS forecasts in winter (December–April).
