From Ben Dubh Craigh in low cloud, gusty wind and wet dreich. Obvious path to south of pair of small lochans and over point 941m. Cairn and outcrop on top but nil visibility. Returned uphill to pair of small lochans begore descent NE on obvious path on NW side of Allt Coire Dubhchraig , all the way back to free carpark at Dalrigh.

From Dalrigh. Up track to Cononish. Direct ascent of Beinn Dubhchraig, then Ben Oss, Ben Lui and out to Beinn a' Chleibh. Followed the path down to the forest, and contoured back around Ben Lui and down the valley before picking up the track back. Clear on Dubhchraig but cloud dropped onto the tops after that. Solo.meltdiceburg22/08/2022
Sunny and becoming very hot; a slight wind on the top was a relief. Great views though becoming hazy i the distance. Descent was uncomfortably hot and risk of sunburn; the path to Dalrigh was relatively dry though.NorfolkPT2113/08/2022

With Dean, Ed & Swot. Staying at By the Way, Tyndrum. From Dalrigh over Beinn Dubhchraig. Snow level at approx.600m, much more than you'd expect in May. Ground surprisingly dry even in the 'boggy' areas. Bitterly cold wind chill approx. -15'C with snow & hail showers. Good views from summit, particularly Ben Lui.Neily There06/05/2021

Another dry but overcast forecast, equals another two Munros, Beinn Dubhchraig (978m) and Ben Oss (1029m), accessed from Dalrigh on the A84 between Crianlarich and Tyndrum, 08:20hrs all in. An early meant there was some low cloud on the way up and on the summit of Beinn Dubhchraig, but this was beginning to clear by the time I got to Ben Oss. Once this past it was an enjoyable walk down with great views down Loch Lomond and to the eastern hills above Tyndrum and Crianlarich. Horribly boggy route up through the old Caledonian forest, but as I discovered on the descent, I had missed the path completely and ascended up through the bog by mistake.chillyman808/07/2020

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

Anticlockwise circuit of Ben Lui, Ben Oss and Beinn Dubhchraig from Dalrigh. Walked into Coire Gaothach then ascended S flank of Stob Garbh. Superior route to the ascent from the W I used in 2017.welshyboyo07/08/2018

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
