In reply to Dan Bailey - UKHillwalking.com:
Interesting, ta - it's a good circuit that for some reason seems to have become markedly more popular in the past three years or so. That can't just be because of the big Glensherup car park (parking in Glen Devon used to be tricky), as that was built quite a few years ago now. I'm rather hankering after these hills from the Devon side as they're currently beyond the legal driving limit from Stirling - the five-miles-beyond thing re the council area happily gets me from Stirling to Tillicoultry or Blackford, but not to Dollar and round the corner (although I recently walked to Innerdownie and back from Tillicoultry).
As the previous poster suggested, the circuit tends to be more often done the other way round, probably because the long gradual slope off Mailer's Knowe / Scad Hill can be a bit of a grind going up but is a stroll coming down. The route suggested also omits the pretty standard short way through the trees to/from Innerdownie. If doing it the way suggested, rather than "ignoring a couple of ladder stiles", cross the second one into the trees as this brings a path (getting slightly sitka-encroached at the top, but not too bad) which brings the big bend in the forest track pretty quickly - it cuts off a corner compared with going down further then in sideways.
Re the "little sheltered 'seat' built into the side of a crag" just west of Innerdownie summit, my understanding is that this isn't really a crag as such, rather a quarry (similar to the one at the top of Colsnaur), as the hut - which still has walls but no roof - was used by the men who built the wall along the ridge. I'm not 100% sure of the details but I believe the builders were the father and possibly uncle of the two Shand brothers, Willie and Graham, who appear at nos.82 and 83 in the list of Munroists. The Shands were Crook of Devon people.
The other way to finish if doing it anticlockwise is to stay on the outside of the trees right down towards Burnfoot then follow the good paths and tracks back to Glensherup via the old campsite etc - that's become my favourite way of finishing these days, particularly if just climbing Innerdownie and wanting to make a little circuit of it.
