]Feel the spray from a 200-foot waterfall on this flat, family-friendly hike. The trail follows an old roadbed through young forest, approaching the Firehole River. Turn west at the Fairy Falls Trail proper and go another 1.4 miles to a grotto where the plume of Fairy Falls plunges over a cliff. When trail crews finish constructing a viewing platform for Grand Prismatic Spring (scheduled for 2018), you can also access Fairy Falls from a trailhead 1 mile south of Midway Geyser Basin, shortening the round trip to 5 miles. This hike can easily be combined with other trails for a longer loop.
