Maah Daah Hey Trail, Theodore Roosevelt National Park, North Dacota, USA
The 144-mile Maah Daah Hey Trail, which cuts through the heart of the Badlands, is the longest singletrack mountain-biking route in the country. And it’s great for hiking, too. You’ll go through three units of the park, including the remote Elkhorn Ranch, where Theodore Roosevelt had a cabin, and the Little Missouri National Grasslands. Expect solitude among swaying prairie grass and forests of juniper trees.
