The Greatest Adventures On Earth

First up, a disclaimer, I suffer from an addiction to travel and adventure. It only takes a flick through the venerable orange-bound pages of the National Geographic to send me off on daydreams of epic landscapes and wild wilderness. So this post is in essence adventure geekery, an attempt to define the undefinable -- the best adventures on Earth.

I present to you 10 adventures. Adventures that I would argue are the greatest on Earth. This, of course, is entirely subjective. But as a general condition of entry, I'd give my eye teeth for any of these experiences.

The adventures are split into 3 categories. First up are the classics, stuff like the Inca Trail; you would have seen them on countless lists, but that doesn't make them any less compelling. They are the must-do's that most of us will have on our lists. Then there are the up and coming adventures, trips that are fast emerging in the shadow of the classics, the destinations (Ethiopia anyone?) are edgier, the trails less crowded and they have a degree of pioneering kudos to them. Finally we have the softer, more peaceful adventures. There may not be the same sense of achievement of completing a demanding trek, but the peace and beauty of kayaking a wild coast and camping on deserted beaches is hard to beat.
