Glacier National Park in December: What to Expect

What Is the Weather Like at Glacier National Park in December?

December is full winter at Glacier. At the West Glacier station (lower elevation, the most accessible part of the park), historical normals from 1991–2020 show an average high of 29°F (-2°C) and an average low of 20°F (-7°C). Average snowfall at that station is 31 inches for December — one of the snowier months. Precipitation falls on roughly 17 days.

Expect significant day-to-day variation: a warm front can dump a foot of wet snow, then a clear cold snap follows at -5°F or below. Daylight is limited — roughly 8.4 hours (sunrise around 8:19 AM, sunset around 4:41 PM in late December). Plan outdoor activities for the middle of the day and be back at your car before dark.

What Is Open at Glacier National Park in December?

December is Glacier's deepest off-season. Most visitor services are closed, but the park itself remains accessible.

No food or fuel is available inside the park in December. Pack everything before you enter. The nearest full-service options are in West Glacier (limited winter hours) or Columbia Falls, 22 miles from the west entrance.

Which Roads Are Open at Glacier in December?

Going-to-the-Sun Road closes in stages each fall. The alpine section from Avalanche Creek through Logan Pass to St. Mary closes around the third Monday in October and stays closed until late June or early July the following year. By December only one short stretch remains driveable.

The drive from West Glacier to Lake McDonald Lodge takes about 25 minutes. The road follows the lake through old-growth cedar forest — beautiful in snow. It can close temporarily after major storms; check NPS road conditions before arriving.

What Can You Do at Glacier National Park in December?

December activity centers on the Apgar area and the Lake McDonald corridor. Snowshoes and cross-country skis open up terrain that cars can't reach.

Snowshoeing: the best starting point is the Apgar area, where established routes follow McDonald Creek through old-growth forest. Recommended December routes: the McDonald Falls route (~4 miles round trip, easy, follows the paved road to the falls — ideal first snowshoe), Rocky Point (~6 miles, moderate, lake views along McDonald Creek), Apgar Lookout (10.5 miles, strenuous, panoramic winter views when conditions allow), and Polebridge / Big Prairie (4 miles, flat, excellent wildlife corridor — the road is closed to vehicles, so ski or snowshoe from the gate). No snowshoe rentals are available inside the park in winter; rent from outfitters in West Glacier, Columbia Falls, or Whitefish before entering. Five NPS-authorized commercial guide operators run winter trips — see the NPS guided winter activities page for the full list.

Cross-country skiing: the same routes double as Nordic ski terrain. The Autumn Creek Trail at Marias Pass (accessible year-round, just east of the park boundary) is 6 miles and moderately challenging. Snowmobiles are prohibited throughout all of Glacier National Park, so trails stay peaceful.

Scenic drive to Lake McDonald: even non-hikers get strong value from the 11-mile drive along the lake. The surface may be partially frozen, the cedars hang heavy with snow, and the Lodge parking area offers views down the lake toward peaks that are completely unreachable in December — one of the most dramatic winter photographs in any national park, requiring nothing more than a brief walk from your car. Nearby downhill skiing: Whitefish Mountain Resort, 35 miles from the west entrance, typically opens by mid-December and is one of Montana's largest ski areas. LOGE Glacier MT (formerly Izaak Walton Inn) in Essex — 27 miles east — has on-site cross-country and snowshoe trails with rentals, a restaurant, and an Amtrak Empire Builder stop, making it reachable without a car.

What Wildlife Can You See at Glacier in December?

December is excellent for large mammal sightings. Bears are hibernating, reducing foot traffic competition, and ungulates have moved to lower elevations where they're visible from roads and easy routes.

In December, focus on the Lake McDonald/Apgar corridor (deer, waterfowl, ravens) and Two Dog Flats near St. Mary (elk). The North Fork area, accessible only by ski or snowshoe in December, offers the best chance of spotting wolves and moose in complete solitude.

Where to Stay for a December Trip to Glacier

All in-park lodges — Lake McDonald Lodge, Many Glacier Hotel, Rising Sun Motor Inn — close at the end of summer (typically September). There is no in-park lodging in December. Book well ahead — winter inventory near Glacier is thin, and Whitefish ski-season demand is real.

Primitive camping: Apgar Campground Loop B and St. Mary Campground are open year-round — first-come, first-served, vault toilets only, no running water. Backcountry camping is permitted with a permit available in-person at the Apgar Backcountry Permit office (up to 24 hours in advance).

Fees, Permits & Reservations for December at Glacier

Glacier charges a reduced winter entrance fee from November 1 through April 30. There are no fee-free days in December 2026.

The park does not accept cash — pay with credit or debit card. Non-US residents pay an additional $100 surcharge per person (age 16+) effective 2026. No vehicle reservations or timed-entry permits are required for December visits — or at any point in 2026, as NPS has eliminated the reservation system for this season.

What to Pack and Safety Essentials for December at Glacier

December visits require serious winter gear. No park services are open, cell service is minimal in most areas, and weather can deteriorate in under an hour.

Gear checklist: heavy insulated jacket (down or synthetic, rated to 0°F or below); waterproof shell layer, top and bottom; merino wool base layers (avoid cotton entirely — cotton kills in wet cold); insulated, waterproof boots rated to -20°F or colder; microspikes or Yaktrax for icy roads and trail starts; snowshoes if venturing off the road (rentals available in West Glacier and Whitefish); trekking poles for snow stability; warm hat, balaclava, and insulated gloves or mittens; hand warmers and toe warmers with extras in your pack; 2+ liters of water (no water available at park facilities in December); 1–2 days' worth of food and snacks; offline maps — GPS or downloaded topo maps, as cell signal is very limited; bear spray (mountain lions and other wildlife active year-round); and an emergency bivy or space blanket.

Safety priorities: avalanche awareness is critical for any backcountry travel beyond the main road — check Avalanche.org for the Flathead/West Glacier forecast before any off-trail travel. Avoid frozen lakes — ice thickness on Lake McDonald and other park lakes is unreliable; do not walk on frozen water. Notify someone of your plans and expected return time. Four-wheel drive or all-wheel drive with winter tires is strongly recommended for driving in December conditions.
