Map & Elevation
About this Route
This is the standard walker’s out-and-back ascent of An Teallach’s main Munro, Bidein a’ Ghlas Thuill, rather than the committing Corrag Bhuidhe traverse. The GPX-derived route measures 11.8 km, gains 1021 m and has a walking-time estimate of 4h 4m.
The recorded line leaves Dundonnell on the stalkers’ path into Coir’ a’ Mhuilinn, then climbs increasingly steep sandstone, sand and scree to the summit trig. The top gives a close view across to Sgùrr Fiona and the serrated Corrag Bhuidhe ridge. Return by the same northern approach.
This is a serious and remote Northwest Highlands mountain day with sustained ascent, loose upper ground and full exposure to rapidly changing weather. Carry full hill kit, an independent map and compass, and enough food and water; turn back if wind, cloud or poor visibility makes the upper slopes unsafe.
A direct route to one of Scotland’s great viewpoints, without committing to An Teallach’s famous scrambling traverse.

Route Waypoints
Start from the A832 lay-by and follow the clear stalkers’ path away from the road.
Continue into the coire as the path steepens and the terrain becomes rougher.
Climb the loose sandy and sandstone ground carefully, keeping to the established line.
Reach the 1,062 m summit trig. Do not continue onto Corrag Bhuidhe unless equipped and experienced for the separate scrambling traverse.
Retrace the northern ascent route to the A832 lay-by.
Essential Tips
This GPX is the Bidein-only out-and-back. The exposed Grade 3 Corrag Bhuidhe scramble and full two-Munro traverse are outside this route.
Check a specialist mountain forecast, carry waterproofs, warm layers, food, water, headtorch and independent navigation, and allow extra time on loose ground.
