Adventurers forget the Rocky Mountains, for Colorado's most intrepid landscapes lie within the Great Sand Dunes National Park.

Whether you skirt the edge of the park to take in its creek or lose yourself in its centre for a night under the stars, this is a national park you'll never forget.
Best for backpackers: Canyonlands National Park
This Utah park is a great place for escaping the crowds of Arches National Park. It stretches for well over 500 square miles and is best explored with nothing but a rucksack and your own two feet.

What's great about Haleakala is the sheer quantity of activities on offer here. The Hawaiian park is a haven for active families, with hiking and mountain-biking from the top of a volcano, miles of coastline and no shortage of camping spots.
