Some of the most spectacular landscapes on earth are in America's national parks. Think Yellowstone, and Yosemite - and I'm sure you get the picture.
In 2016 the National Park Service, the government body which protects and maintains America's 59 national parks and historic landmarks turns 100 years old. The NPS is desperate to ensure the parks are at their best for the centenary, so what better time to visit.
The parks are full of granite cliffs; stunning waterfalls, and incredible geysers spurting hundreds of feet high. Nature at its best, so why not mark the anniversary with a visit!
