Barry Stone, author of 1001 Walks You Must Experience Before You Die, delves into some of the lesser-known aspects of the world's most famous - and not-quite-famous-yet - trails.

The perfect accompaniment to practical guidebooks, Stone relates how slings and carabiners kept him from falling headlong off the Sydney Harbour Bridge, and reports on the progress of the continental-wide monster, the Trans Canada Trail, gaps in which are still being filled by countless grass-roots communities.

With walks that will appeal to everyone regardless of ability, The 50 Greatest Walks of the World includes British classics such as the Pennine Way, Offa's Dyke Path, and the Old Man of Hoy as well as personal favourites such as Italy's Cinque Terre Classic and the Isle of Skye's Trotternish Ridge, one of Britain's finest ridge traverses with almost 2,500m of ascents. Whether it's a climb, a stroll, or a life-changing slog, this book has the walk for you.
