Just ¼ mile north of the Window trailhead is the Door trailhead. The trailheads are located in the same large parking area located between milepost 2.5 and 2.8 on the Badlands Loop Road. The Door trailhead is near the northern end of the parking area at milepost 2.5. To reach the trailhead from the Ben Reifel Visitor Center, drive about 2.3 miles northeast on the Badlands Loop Road. Both the large paved parking area and the trailhead are on the south (compass east) side of the road.
The trail is rated as easy by the National Park Service. The first 700 feet of the trail is an ADA-compliant boardwalk with handrails at inclines and elevated locations. Like the Window Trail, the boardwalk provides close-up views of the landscape that aren't possible from the road. About 100 feet before the end of the boardwalk, a short set of stairs leads down to the badlands.
The remaining 0.3 miles of the trail may not be suitable for all visitors because it crosses the natural surface of the badlands with only a series of yellow posts to mark the route. Deep ravines have been eroded into the landscape on both sides of the trail. When wet, the bentonite clay expands and is extremely slippery. The round-trip distance is 0.9 miles.
This is a very heavily trafficked trail due to its short distance, easy rating, and proximity to the road. If you are looking for solitude, this probably isn't the trail for you. We did notice that many people stayed near the boardwalk and didn't venture out very far into the badlands. We walked the trail in August 2017 during our visit to Badlands National Park.
