Hi Eddie,
If your in the Gairloch area:
Tollie path. Park at Loch Maree ( just before road leaves loch), cycle towards Gairloch, there’s a path on right that takes you up off road (can be dodgy to locate) and round down to pub. More road action up and out of Gairloch towards, Poolewe. Tollie path back to car (good technical path both up and down).
Poolewe to Fionn Loch (Carnmore bothy) Waymarked path into Kernsary Estate, at workers house bridge, go towards forest then look for right turn (very muddy path) on right, wrong road climbs up through the trees to the left. Right path is a muddy, cow trodden forest path that takes you upto a fence, then fantastic ST all the way to the Bothy. I went on and came back Gruinard, but Fatty does run bog well and still a good bit of hike a bike. SO, return same way.
There is a loop from Kinlochewe that goes up round the heights to Lochan Fada. Then up round past East side of Slioch and back along river to carpark. This has a little hike a bike but is very techy in places.
Most of the runs do include some Hike a bike but are rewarded by great trails. 8)
cheers
