While Big Sky might be best known for skiing and snowboarding, winter hiking here is also world-class. Tucked in the middle of the mighty Madison Range, Big Sky offers endless hiking opportunities. The sprawling Gallatin Range sits just across the Gallatin River, and Yellowstone National Park is around the corner. There’s no better place to experience Montana’s wilderness than beneath a fresh coat of powder.
Winter Trails:
Ousel Falls
1.6 miles round trip - Ousel Falls is one of Big Sky’s most popular hikes. The trail sees steady year-round traffic, making it a good, short winter hike conveniently located near Town Center. Enjoy the forested scenery as you make your way through the South Fork Ravine and up to the waterfalls.
Hummocks
3 miles round trip - Hummocks is a dog-friendly trail within sight of Big Sky's town center. It's known for three lollipop loops along rolling hills, making it popular among users who want to customize the length of their hike.
Uplands Trail
2 miles round trip - Taking off at the same trailhead as Hummocks, Uplands is a steady uphill climb for the first mile, bringing hikers to an incredible viewpoint of Lone Mountain, Cedar Mountain, and Beehive Basin. To create a much larger loop, hikers can join the Hummocks trail via Adam's Connector halfway through the uphill.
Lava Lake
6 miles round trip - Lava Lake is located near the 35 MPH Bridge in the Gallatin Canyon. The trail heads into the mountains along Cascade Creek and delivers you to an outstanding alpine lake in the vast Lee Metcalf Wilderness.
Beehive Basin
6.6 miles round trip - Voted one of the best hikes in the world, Beehive Basin starts in the high country and allows you to travel on a well-trodden trail through a series of meadows into a stunning alpine cirque. Be advised that this trail is rated moderately difficult and the snow can be deep, making travel challenging. It’s also imperative to watch out for backcountry skiers and snowboarders and practice avalanche safety.
Safety First:
While Big Sky’s trails are breathtaking, the mountain environment is unpredictable. Whether you’re trekking through a mid-January freeze or navigating the "shoulder season" where winter and spring collide, preparation is your best piece of gear.
Traction is Non-Negotiable
In the shoulder season, melting snow during the day freezes into "black ice" by morning. Even on popular trails like Ousel Falls, microspikes or crampons are essential. Don’t rely on boot tread alone; having extra grip can be the difference between a scenic hike and a nasty fall.
Master the Layering Game
Montana weather can shift in minutes. Follow the three-layer rule:
-
Base Layer: Moisture-wicking (no cotton!) to keep sweat off your skin.
-
Mid-Layer: An insulating fleece or "puffy" jacket to trap heat.
-
Outer Shell: A windproof and waterproof layer to protect against the elements.
Hydration & Fuel
You might not feel as thirsty in the cold, but high-altitude hiking is dehydrating. Keep your water bottle inside your pack (or use an insulated sleeve) to prevent the mouthpiece from freezing. Pack high-energy snacks to keep your internal engine running warm.
Know Before You Go
-
Have a Plan: Always tell someone your specific route and expected return time.
-
Check the Forecast: High-country winds can drop temperatures well below zero in an instant.
-
Wildlife Awareness: Bears may be hibernating in deep winter, but they emerge hungry in early spring. Carry bear spray and know how to use it year-round.
