Remarkable Treks is a compendium of exhilarating walks from around the planet – some lasting weeks, some lasting just a few days, but all of them set against spectacular backdrops. Colin Salter has assembled 52 of the world's top-rated trails, and the treks range in length from one-day hikes, to three-day hikes, to walks of almost expeditionary length. Thankfully, some of the longer routes, such as the Continental Divide Trail in North America, which traverses the Rockies from Mexico to Canada, can be split up into sections. There's something for everyone, from smaller challenges for the completists, to more difficult treks for the thrill-seeking backpackers, to treks that will satisfy the most curious of history buffs.
