Camping in Montana

Montana

Big Sky Country

Montana is the fourth-largest state in the country and contains some of the most consequential wilderness on the continent. Glacier National Park anchors the northwest, where the Going-to-the-Sun Road crests Logan Pass between glacier-carved cirques the size of small towns. The Bob Marshall Wilderness Complex south of Glacier is the largest roadless area in the Lower 48 outside Alaska — over 1.5 million acres of grizzly habitat and snowmelt rivers without a single developed campground in its interior. Yellowstone's north and west entrances both sit in Montana, and the Beartooth Highway out of Red Lodge climbs to 10,947 feet on its way to Cooke City. Add the Flathead Lake basin, the Absaroka peaks above Paradise Valley, and a state park system that runs from prairie badlands to alpine reservoirs, and Montana delivers a camping landscape that rewards ambitious itineraries and tolerates none of the shortcuts.

No. 1

Apgar Campground

Recreation.gov · MT

Glacier's largest campground sits at the foot of Lake McDonald with 194 sites spread across loops in a cedar-hemlock forest. Apgar is the west-side basecamp for Going-to-the-Sun Road, the Lake McDonald boat shuttle, and the Apgar Village amenities (general store, restaurant, ranger station). Most loops accept reservations through Recreation.gov six months out and book solid for July and August within minutes; a small first-come block fills by mid-morning in summer. Lake McDonald's polychromatic pebbles at the campground beach are one of the most photographed shorelines in the park.

When to go

Montana's weather is dominated by the Continental Divide, which splits the state into a Pacific-influenced western half and a continental eastern half. Glacier and the Flathead Basin see more rain and milder temperatures; the eastern plains swing from 100°F summer afternoons to -30°F winter cold snaps. Afternoon thunderstorms build over the mountains from mid-June through August and can produce lightning, hail, and brief but intense downpours. Pack layers regardless of season — a 75°F valley afternoon can become a 35°F evening at a mountain campground. Wildfire smoke is increasingly a factor from late July through early September; check airnow.gov before backcountry trips.

Spring

Apr–May

Shoulder season with limited high-country access. Going-to-the-Sun Road typically opens between mid-June and the first week of July depending on snowpack — Glacier's interior is largely closed in April and May. Lower-elevation campgrounds at St. Mary, Apgar, and around Flathead Lake open through May. Wildlife is highly active — bears emerging from dens, calving elk in late May, migrating sandhill cranes in eastern Montana. Expect mud, snow squalls, and rivers running high with snowmelt.

Summer

Peak season

Jun–Aug

Peak season. All campgrounds open by late June; Going-to-the-Sun Road typically fully opens in early July. Reserve Glacier sites six months out — Many Glacier, St. Mary, and Two Medicine all book within hours of release. Daytime highs reach 75–85°F in the valleys but drop to 50s on the Continental Divide. Afternoon thunderstorms are common. Wildfire smoke from regional fires can degrade air quality from late July through August. Glacier requires vehicle reservations on Going-to-the-Sun Road in summer.

Fall

Sep–Oct

The most underrated camping season in Montana. September brings the larch turn — western larches in the Bob Marshall, Mission Range, and Glacier's west side glow gold the last two weeks of the month. The elk rut peaks in Yellowstone, crowds drop sharply after Labor Day, and the smoke season usually ends with the first big September rain. Most Glacier campgrounds close mid-September through early October as snow returns to the high country. Nights drop into the 20s. The first significant snow on Logan Pass typically arrives by October 15.

Winter

Nov–Mar

Most developed campgrounds are closed. Mammoth Campground in Yellowstone is the state's only year-round NPS campground. A few private RV parks around Bozeman, Missoula, Kalispell, and West Yellowstone stay open with electric hookups for snowbird and ski-town travelers. Going-to-the-Sun Road closes by mid-October and reopens in pieces through June. Backcountry winter camping is for the well-prepared only — temperatures regularly drop below zero in the valleys and well below in the mountains.

Frequently asked

Peak camping runs late June through August when Going-to-the-Sun Road is open and all Glacier and Yellowstone campgrounds are accessible. September is the connoisseur's pick — the western larches turn gold, elk are rutting in Yellowstone, summer crowds dissipate, and the wildfire smoke usually clears with the first autumn storm. Most Glacier campgrounds close by mid-September; Mammoth at Yellowstone is the only year-round option in the state.
