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 it’s now out of print.
You may be able to get hold of copies from second-hand booksellers such as Amazon or eBay. However, on Ramblers’ website, you can read the book text HERE, or if you visit their main page HERE and search ‘navigation and leadership’ several other options on the subject will come up.
