Door Trail 0.75 miles/1.2 km (round trip) Easy. An accessible ¼ mile boardwalk leads through a break in the Badlands Wall known as "the Door" and to a view of the Badlands. From there, the maintained trail ends. Travel beyond this point is at your own risk. Watch for drop-offs. Window Trail 0.25 miles/0.4 km (round trip) Easy. This short trail leads to a natural window in the Badlands Wall with a view of an intricately eroded canyon. Please stay on the trail. Notch Trail 1.5 miles/2.4 km (round trip) Moderate to strenuous. After meandering through a canyon, this trail climbs a log ladder and follows a ledge to "the Notch" for a dramatic view of the White River Valley. Trail begins at the south end of the Door and Window parking area. Watch for drop-offs. Not recommended for anyone with a fear of heights. Treacherous during or after heavy rains.
