Notch Trail

Find the Notch trailhead at the south end of the shared Door and Window lot; Door and Window are different short walks from the same access. The Notch path leaves the parking area and threads through a canyon before the climb begins. The tread is natural ground rather than a boardwalk, with loose gravel along the route. This canyon section is the lead-in, building toward the change in height at the ladder. Keep to the Notch route as it meanders; don’t confuse it with the nearby boardwalk hikes.

The fixed ladder is the route’s crux. Above it, the path follows a ledge with drop-offs and loose gravel. This is where the short distance stops feeling like a casual stroll: watch every step and give other hikers room at the ladder. At busy times, slower climbs can hold up the line, so allow some slack instead of assuming the mileage guarantees a quick trip. If ladders or heights make you uneasy, turn back before the exposed section rather than talking yourself into it. You’ll use the same climb on the way down. Wet weather matters here too: the trail can be treacherous during or after rain or snow.

The narrow channels and sharp ridges belong to an actively eroding landscape, not a set of old, rounded hills. Badlands layers accumulated over tens of millions of years from ancient seas, rivers and wind. About half a million years ago, the Cheyenne and White Rivers began cutting through them, creating the canyons and peaks visitors see now; erosion continues today. On this walk, that story is close at hand: you enter a canyon, climb to a ledge, then look out over the much broader White River Valley.

At the end, the ledge opens onto the White River Valley, with eroded formations in front and open prairie beyond. Give yourself a few minutes to look around instead of treating the overlook as a quick turnaround. The view is the trail’s reason to go, paired with the ladder climb that gets you there. For a photo, keep a nearby ridge in the foreground; it gives the broad valley a sense of scale and anchors the view to the Notch.

Park in the Door and Window area and walk to its south end; the shared lot has parking for autos and buses/RVs, a picnic shelter and restrooms. Allow 1.5 to 2 hours for the round trip, the climb and a proper look from the ledge. Wear shoes with good grip and ankle support, as recommended for the loose, uneven route. Pets aren’t allowed on park trails. This is a poor choice when the footing is wet or when ladders and exposed drop-offs will take the fun out of the day. If you want a low-effort stop instead, Door Trail and Window Trail are nearby boardwalk routes with a very different kind of visit.
