I love this series of books as they have made such a difference to my family holidays and weekends. The walks themselves are breath-taking, but most important are the checklists and activities that keep the children running around and occupied. This book is over a decade old now, though the only significant changes we've encountered have been in forested areas - which I'd expect as all Lakeland forests are living/working forests, so they can change from week to week. You should always carry a current OS map anyway when walking, so you shouldn't have any problems. A great book.
