I'm glad to see the directions for this section have been updated and some very discouraging user reports removed. In fact as Iain Harper says in his CWT guide, all you have to do now as far as Garrygualach is follow the bulldozed forestry track, boring but easy. The cottages at Garrygualach are no longer deserted but being refurbished and there is now (May 2017) a nice new bridge over the formerly difficult burn there.

The main problem I found on this section was finding somewhere to stick a tent up, the very messy tree felling has left almost all the terrain completely uncampable. Eventually I found a tiny flat pitch on a knoll just east of the cottages and new bridge at Garrygualach, a nice view and an Osprey fishing on the loch were bonuses but considering I'd walked all the way from Fort Augustus this made it a long day. If you can stand an even longer day there's also a good pitch on the north side of the bridge over the Garry, but bear in mind that getting there from Garrygualach is slow and very hard going. Once over the new bridge, the forestry track runs out - don't go down to the right of the second cottage that's being refurbished, you need to hop up and keep to the left of the fence line above it. The trail becomes a quagmire and the Allt Choire a'Bhalachain is baffling although easy to cross in dry weather. This was a good job as I crossed it three times, in confusion! It was about the only place on the entire SNT the WalkHighlands GPX waypoints let me down. Eventually I just doggedly followed my compass through the trackless bog north towards the Garry.

I now think with hindsight it would be much easier to follow the route given by Iain Harper in his CWT guide, which is to say you head straight on up to the new small building and take the new forestry track southwest, the map then shows a footbridge at about 1315 0025 at which you then presumably head north through the forestry. Certainly when you get near the Garry bridge at about 130 010 you see what looks like a clear path coming uphill from the south. This is all surmise on my part but would be worth investigating as an alternative, because the bog between the Allt Choire a'Bhalachain and the Garry is just awful. Good luck!
