The National Park Service manages more than 21,000 miles of hiking trails across 85 million acres of land. Choosing the right trails is no easy task. Distance and difficulty. Its all there. Whether it's sliding down snow hills along Mount Rainier's Skyline Trail, bounding down sand dunes at Death Valley, or walking among Bryce Canyon's colorful hoodoos under a fresh blanket of snow, these trails are sure to make you smile (and sweat, and maybe even crytears of joy, of course!).
