Just back from a great weekend camping in Blair Atholl (surely the best campsite in Scotland). Nipped into Escape Route which seems like a great bike shop and got a couple of local maps. Anyways plumped for the following route .
Blair Atholl > Killievrankie(under A9) > through Forest and loop to the top > Lovely Singletrack to Pitlochry GC > Moulin > Massive climb to Bealach na Searmain > Great descent to Killiekrankie > Road to Blair Atholl.
I'd Imagine that this Is a fairly common route but would have to say the descent to Killiekrankie has to be one of the best Ive done in a while despite getting covered in Sheep cack. Was kinda gutted I couldn't do more but hoping to venture back up next month. Here's a few pics.
Only slight downside to the route would be some of the gates heading up the hill are very tricky to get your bike through and my bike is on the heavy side.
