What to Expect

This is Yellowstone's most rewarding summit hike for the effort — a wide, old service road that climbs steadily from the Chittenden Road trailhead to the top of Mount Washburn without ever throwing a scramble or a surprise at you. The trail is broad enough that you could walk side by side with a friend, which makes the roughly five-mile approach feel more like a conversation than a slog. As you gain elevation, the lodgepole forest thins out and gives way to wide-open alpine meadows where bighorn sheep graze with zero concern for your camera. Wildflowers carpet the slopes in July and early August. The summit payoff is enormous — a 360-degree panorama that takes in the Grand Canyon of the Yellowstone, the Absaroka Range, and on a clear day, the Tetons poking up on the southern horizon. There is a fire lookout shelter at the top with interpretive displays, which doubles as a welcome windbreak. This trail is perfect for hikers who want a legitimate summit experience without needing technical skills or iron knees.

Safety Advisory

Lightning is the primary danger on this hike. The upper half of the trail is completely exposed with no shelter until the summit lookout. If you see dark clouds building or hear thunder, turn around immediately — do not try to push for the top.

You may share the road with NPS service vehicles and mountain bikers on the descent. Stay to the right on blind curves, and keep your head up rather than buried in your phone on the way down.

Pro Tips

Trail Tip

Start by 8:00 AM — afternoon thunderstorms roll in fast above treeline, and the Chittenden lot fills up by mid-morning in July and August. If the lot is full, the Dunraven Pass trailhead on the other side of Washburn is slightly longer but often has parking.

Trail Tip

Bring a wind shell even if it is 75 degrees at the trailhead. The summit is fully exposed and temperatures can drop twenty degrees with a stiff wind. Layering is more important here than on almost any other Yellowstone day hike.

Trail Tip

Pause at the broad alpine saddle about three-quarters of the way up — this is where bighorn sheep sightings are most common, especially in the morning. A pair of compact binoculars will earn their weight here. The interpretive displays inside the summit lookout are worth lingering over rather than just snapping a photo and turning around.
