It is a generally accepted fact that the traditional exit from Beinn Heasgarnich to the road linking glens Lochay and Lyon involves a tramp across interminable bog. I'm really just uploading this little snippet in case anyone in the future searches for trip reports and wonders how best to avoid this rather unpleasant section of an otherwise fine day out.
I did Creag Mhor and Beinn Heasgarnich on Sunday via the traditional route (i.e. walking west along the hydro track and then up onto Creag Mhor before dropping down and re-ascending to Beinn Heasgarnich). However, I decided to try a different tack on the way out, having had some success with this strategy in the past.
Effectively I followed the Allt Tarsuinn, basically from its outflow of the tiny lochan, just a bit below the summit. The ground on the north side of this stream is not at all boggy, and for much of its length has lovely walking.

Streams wash silt and rocks down when in spate, and long-term this results in slightly elevated banks forming at their side. For sure there are little bits where one has to negotiate a little (due to mini-waterfalls) off to the side, but the quality of the walking is superb. It's also possible to pick out little trails left by sheep and deer, who in my experience also follow such water courses for probably the same reasons.



The route is slightly convoluted, but it is very pleasant. It is also interesting, because with every twist of the river a new view opens up ahead, instead of looking at one section of bog after another when the usual route is followed.
