Really lovely walk, been more times than I can remember. Only problem is it gets very busy in the summer - on a Sunday afternoon in nice weather the paths are as busy as supermarket aisles on 2 for 1 day! Some odd sheep by the river occasionally and fishermen. Don't be put off though, everyone should do this walk at least once - take an OS map or good guide book and spot all the named rock formations you'll see from the river bank.
