Fairy Falls Trail is a 6.6-mile easy both-ways trail that runs along the scenic Grand Prismatic Spring, through a forest that burned down in 1988 but is slowly regenerating, passing by the bottom of one of Yellowstone's tallest falls, ending with a fantastic backcountry geyser.

The trail is very popular and can get crowded, so do not expect any solitude.

The trailhead is located on the Old Faithful to Madison road, about a mile from Midway Geyser Basin. The trail starts by crossing the Firehole River Bridge, continuing on the Fountain Freight Road along the south bank of Midway Geyser Basin until reaching the massive and beautifully colored 370-foot Grand Prismatic Spring.

The trail continues through the slowly regenerating forest, which after the fire provided a home to a large number of species.

Fairy Falls, which you will reach after about 2.5 miles, is formed by Fairy Creek shooting over the edge of the Madison Plateau, plunging 197 feet to the pool at the bottom.
