Agree with everything that everyone else has said in their review, for white water there is none better, but alas my skills are not up to much in the book
As a novice open canoeist I actually bought this (and consider it good value) for the info on the Grade 1/2 rivers as well as all the lakes - it has all the things I was trying to find out but didn't know who to ask. The descriptions with route stars, scenery info and access agreements has been hugely useful for a novice who doesn't want to get into trouble for running down the river from Keswick to Portinscale after 4pm in summer, or going onto Bassenthwaite without the right permit
simply marvellous
