Bonnie Prince Charlie's Cave

I drove out near Stirling to go caching on the Touch Hills. It was a 18km route but I actually did 21km as I realised I dropped my cagoule at one point and walked back 1.5km until I found it again. 

This is Touch Burn waterfall  / Gilmour's Linn but rumour has it that Bonnie Prince Charlie hid in the cave here.
