Hiking Yellowstone National Park
A long day hike or overnighter for experienced hikers. This is a great hike to Fairy Falls, Imperial Geyser, Little Firehole Meadows, and Mystic Falls. It ends at Biscuit Basin Trailhead (OK4), 2 miles up the road, so if you want to avoid walking this stretch when you finish, leave a vehicle or bicycle here.
When I first hiked this route in the mid-1990s, it was a route-finding challenge, but when I hiked it again in 2011, the trail was in great shape all the way. From the trailhead follow Fairy Flats Trail as it crosses the Firehole River on a
bridge and skirts the west side of the Midway Geyser Basin. You can often see large numbers of people viewing Grand Prismatic Spring. In less than 1 mile, turn left (west) off the road onto Fairy Falls Trail.
