Hiking the Door Trail in Badlands National Park is like a two-for-one deal. The trail begins amid the prairie’s level and open grasslands. It ends in a bizarre menagerie of spires and domes encased by striped, twisting canyon walls.
The trail is located two miles northeast of the Ben Reifel Visitor Center (where a trail guide is available for purchase) on the Loop Road. Pull over in the large Door and Window parking area. The 0.75-mile trail starts in the parking lot’s northern end.
Among the best times to hike the trail is sunrise when dawn lights the rock formations in unique colorations:
