I was in Glen Lyon both days this weekend funnily enough. it really is an amazing place (I think I'll be taking Mr and Mrs Goff there later this month), not visited that much by tourists since it's a dead end. I've never made it to the Tigh na Cailleach yet, was going to do it this summer but never got round to it. might save it for next summer, I'm not sure it's an autumn or winter trek! besides, she'll probably be inside at this time of year
if you want any advice on what to see, where to stay etc just drop me a line andy at stravaiging.com
Cheers
Andy
