"Hiking books" means two different things, and it helps to know which one is wanted. One kind tells you how to walk a route: stages, maps, where to sleep. The other tells you what it was like to walk it, and is the better choice for an armchair or a long journey home. This guide is the second kind. For the practical side, see our pick of long-distance walking guidebooks.
Walks around Britain
Britain has produced a good run of walking books lately. Lost in the Lakes loops 379 miles around the Lake District with a pub stop never far away, and Edgeland takes the South West Coast Path in sections over about a decade. Across a Waking Land follows the spring north from Lymington to Cape Wrath, and Walking the Bones of Britain reads the country through its geology. Two books follow the English-Scottish border: The Marches and Between Britain.
Walking as a way through something
Plenty of walking books are also books about grief, illness or a life that had stopped working. Wayfarer follows Britain's pilgrim paths, and Finding Hildasay is the story of walking the whole UK coastline. Windswept goes through history to ask why women walk, and Erling Kagge's short Walking: One Step at a Time asks the question more briefly. For more in this vein, see our guide to pilgrimage walks.
Further afield, and further back
Bill Bryson's A Walk in the Woods is still the usual first answer for the Appalachian Trail, and Alan Booth's The Roads to Sata crosses the whole of Japan on foot. Also worth a look: Eric Newby's A Short Walk in the Hindu Kush, Levison Wood's Walking the Americas, and, closer to home, From Source to Sea along the Thames.
