Navigation & Leadership – a manual for walkers
Colin Saunders wrote this book in 1993 for the Ramblers’ Association (as it then was – now just plain Ramblers). It was his first published work, so he has considerable affection for it! A second edition was published in 1994, but both editions are now out of print.
You may be able to get hold of copies from second-hand booksellers such as Amazon or eBay. However, if you visit Ramblers’ website HERE and scroll down to ‘Walk Leadership’, you should find much useful information and tips there.
