Munro · Arrochar & Trossachs
Ben Lui (Beinn Laoigh)
Ben Lui (Beinn Laoigh) (1131m) is a prominent mountain in the Arrochar Alps and the Trossachs, where the Highlands meet the Lowlands. With 876m of prominence it stands well apart from its neighbours, a genuinely isolated summit that demands a dedicated day. The summit, marked by a cairn, gives views of Loch Lomond, the Firth of Clyde and the Glasgow skyline on clear days. The nearest town is Oban in Stirling.

Standard route · 18km
Standard route
The standard route is a longer walk with a gradual approach covering approximately 18km with 996m of total ascent — a long and demanding day. Lower slopes cross steep wooded slopes of oak and birch above Loch Lomond. Higher up, the terrain changes to rocky mica schist ridges, often steep and broken. Well-maintained paths on popular routes like The Cobbler, but quieter hills have rough, steep ground. The summit is marked by a cairn.
Terrain
Above 700m the ground is fully exposed to weather from all directions. Well-maintained paths on popular routes like The Cobbler, but quieter hills have rough, steep ground. The hill's high prominence means the approach involves significant re-ascent — there are no easy shortcuts from neighbouring peaks.
In winter
In winter, Ben Lui (Beinn Laoigh) is a serious proposition. High rainfall makes ice build-up fast on north-facing slopes. These hills feel bigger than their height suggests in full winter conditions. Daylight is limited in midwinter but marginally better this far south than in the Highlands.
