I started at Crianlarich and picked up the West Highland Way which I followed to Dalrigh where I took the track to Cononish and accessed the ridge to Beinn Dubhcraig. From this summit I crossed to Ben Oss, rounded the head of the valley to gain Ben Lui and then Beinn a Chleibh.
I descended Beinn a Chleibh down the 'front' (head North West) but would have been better returning to the saddle and descending from there as my route was nasty. After fording the River Lochy I gained access to the A86 and a few hours road walking to Dalmally. Follow the old military road to gain access to Beinn Chochuill and from there Beinn Eunaich and Meall Copagach before picking up the Lairig Dhoireann path for the descent into Kinglass.
Follow the Allt Hallater path to gain access to the next ridge at 144417, cut back to summit Beinn nan Aighenan, then back to the saddle to access Bheinn Mhor and Ben Starav, from Ben Starav summit there's a good path down into Glen Etive.
Another hour or so of road walking gives access to the Lairig Gartain, which is a good path that links Glen Etive with Glencoe. There's an opportunity here to do another two Munros - Stob Dubh and Stob Coire Raineach before dropping back into the Lairig Gartain, if doing these take the path straight up the front of Stob Dubh and follow the ridge to Stob Coire Raineach, return to the lowest point between the two and descend the slope to Lairig Gartain.
On reaching Glencoe walk a few hundred yards along the road to pickup the West Highland Way which cuts over the moors to Kinlochleven.
From Kinlochleven gain the Mamores ridge using the Na Gruagaichean path, from here there are any number of Munros that can be summited before dropping into Glen Nevis. The weather was foul when I was doing this section so I took the path over An Garbhanach and followed the path into Glen Nevis.
I saved the long walk into Fort William because I was offered a lift!
