Trail description

A long climb in Yellowstone National Park from the Mount Holmes trailhead on the Mammoth to Norris road over the Winter Creek meadows to the fire lookout on the summit of Mount Holmes, above 3,100 m. It is a long day, and the summit is high, so take it slowly if you are not used to the altitude. Bears live here, so carry bear spray.
