For all of our obsessions with man-made wonders, nothing compares to the creations of Mother Nature. Vast underground cave systems, wild desert landscapes, breathtaking waterfalls, staggering geology and spectacular vestiges of our prehistoric past all remind us of our small place in Earth's story.

Even with our ever-expanding knowledge of the way the world has come to be, some landscapes still leave us utterly perplexed. This is the mystery and the majesty of the natural world. In this book we've attempted to capture just a fraction of what our planet has to offer, and we hope it inspires you to get out and find your own slice of pleasure in the great outdoors.
