Easy Parking

Great option for getting into the backcountry of Badlands National Park. 10 mile round trip hike.

Very flat trail that is 10 miles round trip from the Door Trailhead to the Fossil Exhibit Trail and back. There is also parking along Old Northeast Road. Trail connects with the Saddle Pass Trail. 

Hiking in the summer can be very hot and the trail offers no shade. Beautiful views of the badlands with the chance to escape the crowds during the summer. Wild flowers can be seen on the Medicine Root portion of the trail at certain times of year. Watch for rattlesnakes.
