The Walk

Stage 1: Starting at Glenbrittle

The walk begins at the Glenbrittle car park (grid reference NG410205), located near the Glenbrittle campsite. From here, follow the main eastbound path that starts by ascending a grassy slope. The path is clear and well-used, passing the campsite’s toilet block before heading steadily uphill. The early section offers pleasant views back toward Loch Brittle and the coastline.

Stage 2: The Burn and Scrambling

After approximately 1.2km, you will encounter a fork in the path. Ignore the left-hand route leading to Loch an Fhir-bhallaich and continue along the main trail that follows the Coire Lagan burn. The terrain becomes rougher as the path steepens, winding through rocky sections that may require hands-on scrambling. Grip is essential here, as the rocks can be slippery in wet conditions. Cairns mark the way, providing reassurance for those navigating in poorer visibility.

Stage 3: Coire Lagan Lochan

The final section of the walk leads into Coire Lagan itself. The path gives way to a boulder-strewn area around the lochan at grid reference NG444209. This tranquil body of water is surrounded by dramatic gabbro cliffs, including the imposing Great Stone Shoot leading to Sgùrr Alasdair, the highest peak in the Cuillin range. Take time to rest and soak in the scenery, with views extending toward the islands of Eigg, Muck, Rum, and Canna on clear days.

For those seeking variety, an optional descent route passes the Eas Mòr waterfall, which features a stunning 40-70m drop. This loop adds scenic interest and slightly extends the walk to approximately 9.6km. Be mindful that this route requires extra care on slippery terrain.
