Addendum

I meant to say that the difference between my book and Morag's website's interpretations of the walks was hilarious. The first coast walk we did was level 1 (the easiest available) in the book but a grade 3 (medium to hard) on the web. I guess it just shows how difficult it is to rate these things when so much depends on your fitness and experience. God knows what the Cuillin ridge would be on the website - off the scale presumably! The book takes 'walks' to mean anything you don't actually need climbing ropes for, while I imagine the website has a more tradition view that walking shouldn't involve your hands. Anyway, there are plenty of challenges left there for us.
