Unforgettable Walks to Take Before You Die is the fifth title (2008) in an exciting series of books that will help you search out essential sights and experiences around the world.
Photographers and writers Steve Watkins and Clare Jones draw on their years of international travel experience in selecting thirty of the world’s most inspiring, spectacular and beautiful walks, each of which can be done within the space of a two-week break. …
… not “hiking guidebooks” but certainly inspirational.
Some of the worlds best walks are included in this volume.
Yellowstone
Tour du Mont Blanc (Alps)
Tiger Leaping Gorge (China)
Amalfi Coast (Italy)
Routeburn (New Zealand)
etc.

An interesting list. I wonder what they mean by “Yellowstone”, which is a destination area, not a hike.
And extremely diverse:
“The Freedom Trail is a 2.5 mile red-brick walking trail that leads you to 16 nationally significant historic sites”, while “The Coast to Coast Walk is a 192-mile unofficial and mostly unsignposted long distance footpath in Northern England.”
You could be murdered by bandits on the Takesi Trail in Bolivia, legally purchase sex on the “Canals of Amsterdam”, deplete your credit card reaching “Tiger Leaping Gorge” in China, or get AMS on “Kilimanjaro”.
At first I was perturbed by their lack of parameters, resulting in a complete mish-mash of hiking styles, but then realized they didn’t say “best” hikes, they said “Unforgettable” hikes, which this list undoubtably is, for one reason or another.
Since I’m a sucker for them, I’m happy to have seen another list, and a very interesting one at that.
