Nice one, @steveo. There was a concern raised that a mere grid reference was a thin pretext on which to set out into the wilds. Sensing the innate reasonableness of this point I have constructed a suggested out and back ride;
http://www.mapmyrun.com/routes/view/1858576814
crossing some of the most beautiful country I have ever come across. The trails are mostly gentle with a few harder sections but nothing technical. There is a genuine obstacle in the crossing of the Allt Garbhlach (NN849953) where a bit of hike-a-bike is required if not actual portage but nothing extreme.
The bothy at Ruigh Aiteachain is currently closed for renovation but it does have an associated rudimentary but serviceable toilet which is always open, making this an excellent semi-wild camp spot. (Also home to a small wood of gigantic juniper bushes unique in western Europe.)
Anyone wants to add kilometres need merely add a loop up Glen Eanaich, anyone looking to add metres can simply amble up to the 1000m contour on Mullach Clach a'Bhlair. Anyone a bit tired in the morning can return on quiet tarmac.
Tempted by the emerging temporal and spatial co-ordinates?
