Fairy Falls Trail

The Fairy Falls lot sits south of Midway Geyser Basin and serves the separate Grand Prismatic Overlook route too. Parking is very limited, so it’s the main practical constraint. There’s an information kiosk and bulletin board. A guide reports no toilets or drinking water at the lot; bring water from elsewhere. No trail reservation or activity fee is listed, though normal park entry requirements apply.

Cross the Firehole River bridge onto a wide dirt path. About half a mile from the lot, a left branch climbs gradually to Grand Prismatic Overlook, 0.6 mile each way and about 105 feet above the start. It’s a separate 1.2-mile out-and-back; take it if you want the basin view, then return to the junction. Continue on the main path. About another half mile later, turn left onto a narrower natural trail that heads west beside the Madison Plateau’s high rock wall. Young lodgepole pines line much of the walk. The grade stays gentle, with a final easy rise toward the falls. Return the way you came.

Fairy Creek drops over the edge of the Madison Plateau in a single plunge about 200 feet high. The stream narrows at the top and spreads over rock on its way to the pool below. Wet, uneven ground is reported around the falls; stay on the established path. No official swimming or wading area is identified. For a photo, include the pool and the full cliff around the fall so the height reads clearly.

Much of the route crosses ground burned in 1988. Rather than continuous old forest, you’ll see younger lodgepole pine and open patches where grasses and wildflowers have returned. That new growth supports small animals and birds, although no trail-specific species list was found. The regrowth is part of the walk’s story, not just background scenery.

Members of the 1871 Hayden Survey named Fairy Falls for the graceful drop of the stream. If you want a longer day, the route continues 0.6 mile beyond the falls toward Spray and Imperial geysers; walking out and back adds 1.2 miles. Those geysers are a separate extension beyond the waterfall, and the park’s longer mileage totals don’t clearly say which approach or add-on each includes.
