The stream can be found between Inverarnan and Ardlui, to the West of Geal Loch. The river splits and goes under the A82 with two narrow bridges, south of which there’s a large layby for parking, or there is a very small layby for one vehicle immediately before the Northern bridge. Approach Option A - Walk up the main road a short way, turn off where there’s a minor road closed to vehicles. This road/track continues north, goes under the railway then bends round south up the hillside to where the gorge comes into view. Approach Option B - Follow the North side (TL) bank up from the road, go under the railway bridge as it crosses the river and enter just above the waterfall marked at the 210m contour. Exit – where canyon reaches either of road bridges. From the start there are a few small features, descend either by downclimbing or natural anchors. Halfway down is the main event ~50m high. From the top you can reach lower platforms to get down in a few pitches using rock anchors and the halfway bolts originally placed (TR). A wet line was bolted (March 2025) which starts from double bolts on TR down to a hanging rebelay on the TL just below the chockstone. This line may be challenging during higher flows. After this the canyon continues with more features including one 10m abseil into deep pool. For this abseil there is the option to rig off of a tree (TL) which takes you through the flow; or go through the false floor using the bolts on the boulders (TR; bolted March 2025) for a full void abseil into "the murder hole" *disclosure no murder has taken place!*.
