Chittenden Road–Mount Washburn Trail

Chittenden Road–Mount Washburn is a 5.8-mile out-and-back to Yellowstone’s 10,219-foot Mount Washburn summit. It is the shorter of the two hiking routes to the peak, and a good pick if reaching the lookout is your main goal. Plan on three to five hours. The climb is steady for almost the whole way, and the elevation makes it a moderately strenuous day even though the trail is broad. This is the north-side approach from Chittenden Road; the Dunraven Pass trail is a separate route from the south.

The route starts in forest on a wide gravel service road, then keeps climbing until the trees thin and the track crosses open alpine slopes. There are no named side destinations on this approach; the summit is the payoff. The road-like surface is easier to follow than a narrow tread, but it does not make the grade disappear. Bicycles and occasional service vehicles also use the road, so keep to the established route and give them room. Alpine plants are fragile, and there is no water along the trail.

At the top, a shelter at the base of the fire lookout holds interpretive exhibits. Step outside for the wide summit view; on a clear day, sightlines can reach 20 to 50 miles across Yellowstone. The lookout is one of the park’s three fire stations, staffed from mid-June until the fire season ends. Firefighters live there through the summer to spot smoke, locate fires, and report changes. It is a working post as well as the hike’s destination.

Mount Washburn is a remnant of the Absaroka Volcanics, formed about 50 million years ago. A later eruption, 631,000 years ago, cut the original volcano in half. The part left standing is the northern half you climb today. From the summit, the size of the view makes that story easier to picture: the mountain is one high point in a much larger volcanic landscape.

In July, wildflowers carpet the slopes, and bighorn sheep are often seen near the trail. Keep your eyes on the open hillsides as well as the path, but treat a sighting as a bonus rather than a promise. The route crosses their habitat, so stay on the road and leave animals room.

Start at the Chittenden Road / Mount Washburn North Trailhead, 10.3 miles north of Canyon Village. Parking is limited; there is an information kiosk and a composting toilet at the lot. No reservation or separate trail activity fee is required, though Yellowstone’s entrance fee may apply. Pets are not allowed. Allow time for the return walk to the same parking area.
