About This Route
The Mammoth Hot Springs Terraces snowshoe route offers a beginner-friendly winter adventure in Yellowstone National Park's northern section. Start at the Mammoth Hot Springs Visitor Center and follow the boardwalks turned snowshoe paths around the Lower and Upper Terraces. This 2-3 mile loop showcases steaming travertine formations, frozen cascades, and Liberty Cap, all under a blanket of deep snow. Accessible from the North Entrance in Gardiner, Montana, it's ideal for families or first-timers, with minimal elevation gain under 200 feet. Follow Leave No Trace principles by staying on designated paths to protect fragile hydrothermal features. NPS grooms nearby ski trails, but snowshoers must avoid them per park rules.
Safety Considerations
Winter conditions here include deep snow up to 5 feet, sudden temperature drops to -20°F, and high winds. Hydrothermal hazards like thin ice over scalding vents demand caution; stick to marked boardwalks. Wildlife such as bison and elk roam freely, so carry bear spray and maintain 100 yards distance as per NPS guidelines. Avalanches are low risk on terraces but possible nearby; check daily avalanche forecasts from the Montana Avalanche Center. Yield to skiers on adjacent trails, fill postholes, and turn back if visibility drops below 0.5 miles. REI recommends group travel and a 10 essentials kit for all outings.
Essential Gear
Pack MSR Evo Ascent snowshoes for reliable flotation, adjustable trekking poles with powder baskets, insulated boots like Sorel Caribous, moisture-wicking base layers (Patagonia Capilene), a waterproof shell (Arc'teryx Beta), gaiters, goggles, balaclava, and high-calorie snacks. Navigation essentials include a Gaia GPS app with offline Yellowstone maps and a headlamp with extra batteries.
Emergency Tips
In case of hypothermia or injury, shelter in place with a bivy sack, signal with a whistle (3 blasts), and activate a Garmin inReach for SOS to NPS rangers at 307-344-2109. Mark your location with GPS and conserve energy; rescue can take hours due to remoteness.
