From Dalrigh (NN 34389 29110) - Coille Coire Chuilc - Beinn Dubhchraig - Bealach Buidhe - Ben Oss North Top - Ben Oss. Return by the same route except re-ascent of Beinn Dubhchraig. Generally very wet underfoot until reaching Beinn Dubhchraig ridge, mostly stony paths thereafter.david23020129/04/2019
From Dalrigh, over new bridge and up Coire Choille Chuilc - the engineered path after the bridge soon ends and the quagmire begins, though it was partly frozen today. Then, from the tiny lochan on the shoulder of Beinn Dubhcraig, down into the bealach using the ice/snow ramps through the two craggy areas. Back up to Beinn Dubhcraig and down its NE ridge, but unable to locate the rides etc reported in someone else's log - found a way down streams etc to the 'green' forest track running S, E then N back to Dalrigh.Isbjorn Winter Round10/02/2019

From Dalrigh, avoiding the Slough of Despond, by forest tracks looping east before rejoining the ascent path at the waterfall. NE ridge to Beinn Dubhchraig, via the edge of Coire Garbh to Ben Oss, along the ridge to the NE Top and the lochans that mark the start of the descent path. The little waterfalls on the upper Allt Coire Dubhcraig were beautiful in the sunlight, flowing into malachite and aquamarine pools.Nick Down119/05/2018

Ben Lui excursion.justin99912/08/2015
Big walk from camp site in tyndrum. I ended up walking to Dalrigh as I could not cross the track at Tyndrum due to Network Rail enough said. In the coire gaothach I went to far south so ended up cutting across the snows of central gully and then up to a point just west of sron garbh. The North East ridge was easy but fun. I visited both summits, I then went over to Beinn a chleibh and returned to col with Ben Lui I then contoured round to the col with Ben oss. The North East ridge of Oss was fun as I glissaded down the snow patches. It was then over the subsidiary top and up Beinn dubhchraig. I reversed to the lochans and and went down the path to the north of the allt coire dubhchraig. Lower down this was boggy towards the bottom I turned south crossed the river cononish and picked up the outward path near the bridge under the railway. I returned on the West Highland Way to Tyndrum. I walked 17.5 miles in 9.25 hours with 1830 metres of ascent.isabelle15/06/2015
