Hi Jenny

I tried to book in to Coshieville for 1 night in 2015 and got a rather off putting terse response so changed my plans to have a B&B in Pitlochry the following day instead. However due to various issues I landed up walking Glen Lyon and needing accommodation in the area. I phoned in the morning from Bridge of Balgie and they were happy to take me for a single night that evening. Lovely single en-suite room, friendly hosts and a small kitchenette for guest to prepare their own evening meals. Would recommend it so worth taking the number with you.
If you can't get in then there is a new path - waymarked but not on the map - along the Lyon and then Tay heading towards Aberfeldy with quite a few possible pitches and quite a few fishermens bothies. A lot of these are locked but some are open 3 sided shelters.

Oh thanks Ali that's great info I'm very grateful for your answer and everyone else's advice. Fingers crossed my route should be in Tuesday now!
Jenny
