About This Route
The Fairy Falls Trail in Yellowstone National Park offers runners a stunning 5-mile out-and-back adventure starting from Fairy Falls Overlook near Midway Geyser Basin. This intermediate route features rolling terrain through lodgepole pine forests, with a rewarding payoff at the 197-foot Fairy Falls cascade. Elevation gain is about 250 feet, making it accessible yet challenging for trail runners. Popular in summer, the trail sees heavy foot traffic, but early morning starts help avoid crowds. According to NPS data, this area combines hydrothermal wonders with wildlife hotspots, demanding vigilance. Follow Leave No Trace principles by packing out all waste and staying on designated paths to preserve this fragile ecosystem.
Safety Considerations
Bears pose the top threat here; grizzlies frequent the area, so carry bear spray and make noise on blind curves. NPS recommends groups of four or more for safety. Bison and elk roam meadows; maintain 25 yards distance per park rules. Thermal runoff near the trailhead can scald, so stick to boardwalks as per official guidelines. Weather shifts fast; afternoon thunderstorms are common, so check forecasts via the NPS app. Hydration is critical at Yellowstone's 7,000-foot elevation; dehydration hits runners hard. Watch for thin crust over hot springs, a leading cause of burns per NPS records. Run with a buddy, inform someone of your itinerary, and turn back if fatigued.
Essential Gear
Pack REI Co-op trail running shoes for grip on loose gravel, a CamelBak hydration vest with 2 liters minimum, and Counter Assault bear spray holstered for quick access. Include a Garmin inReach satellite communicator for off-grid SOS, layered clothing like Patagonia Capilene for variable temps, and a first-aid kit with blister treatments. Sunglasses and high-SPF sunscreen combat intense UV at altitude.
