Chittenden Road - Mount Washburn Trail
What to Expect
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.
Trail Details
Pro Tips
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.
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.
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.
