BestHike.com has the most detailed, up-to-date list, on the internet. A good starting point is our list of the top 10 hikes anywhere:
#10) Overland Track, Tasmania

Overland Track, Australia
Wild Tasmania offers the best & most famous walk in Australia. If the roaring 40s winds and driving rain relent, you'll enjoy a nearly otherworldly adventure.
#9) Walker’s Haute Route, Europe
Trek Mt Blanc to the Matterhorn. Ibex and chamois. The European Alps don't get any better than this. You can carry a light pack, staying at mountain huts every night.
#8) Annapurna Circuit, Nepal
A 300km (186mi) circuit. Nowhere else on earth can you get so close to the highest peaks — and still enjoy a warm bed and a tasty meal. This is teahouse trekking at its finest. But get there SOON.
#7) Mt. Kilimanjaro, Tanzania
If you are going to Africa for just one trek, this is it. The highest mountain on the continent, one of the 7 summits, no mountaineering experience necessary.
#6) Glacier North Circle, Montana, USA
Fabulous hike-of-a-lifetime in every possible way. A convenient hiker’s shuttle bus delivers you to the wildest Park in the lower 48 States. Loop into Canada's Waterton National Park, if you wish.
#5) Sunshine to Assiniboine, Alberta, Canada
Mt. Assiniboine is Canada’s Matterhorn, the most picturesque peak. Bus to Sunshine Village Ski Resort on the Continental Divide. Hike out via Wonder Pass and Marvel Lake.
#4) Ausangate Circuit, Peru
Our favourite hike in the Andes is still one of the least well known. You'll share the intensely scenic mountains with thousands of alpacas. Start and finish at Hot Springs.
#3) Tongariro Northern Circuit, New Zealand

Tangariro, New Zealand
The most popular hiking region in the country, a fantastic, eerie volcanic adventure. Climb Mt Doom (from Lord of the Rings) as a sidetrip.
#2) John Muir Trail, California, USA

John Muir Trail, California
The most storied hike in the USA and the best section of the famed Pacific Crest Trail. You can walk for 2 or 3 weeks in the Sierra Nevada mountains of California without crossing a road.
#1) West Coast Trail, BC, Canada
We call the WCT the "best hike in the world". A week walking the remote, isolated, rugged “Shipwreck Coast” of Vancouver Island.
