Why Montana for Road Trips

Montana contains two of the most legendary mountain drives in North America, and neither one disappoints. Going-to-the-Sun Road in Glacier National Park is a 50-mile engineering marvel carved into cliff faces, crossing the Continental Divide at Logan Pass with jaw-dropping views of glacial valleys, alpine meadows, and turquoise lakes. The Beartooth Highway - which Charles Kuralt called the most beautiful drive in America - climbs to nearly 11,000 feet through a landscape of alpine tundra and snowfields that looks more like Tibet than the US.

Beyond the headline drives, Montana delivers something increasingly rare in America: genuine wildness. This is one of the least populated states in the country, with more cattle than people. The roads stretch across open prairies, through forests so thick the sun barely penetrates, and over passes where grizzly bears cross the highway. You will drive for hours without seeing another car.

Montana is also the gateway to Yellowstone from the north, with three park entrances within its borders. The Lamar Valley - accessed from the northeast entrance - is widely considered the best place in the lower 48 to spot wolves, bison herds, and grizzly bears in the wild. Combined with Glacier, a Montana road trip delivers the two most wildlife-rich national parks in America.

Top Montana Road Trip Routes

Mountain drives through some of the wildest terrain in the lower 48.

Timing

Best Time to Visit Montana

Best
Summer (Jul-Aug)

Going-to-the-Sun Road is fully open (usually by late June). All trails accessible, wildflowers peak in July, and days are long (sunset after 9 PM). This is peak season - expect crowds at Glacier. Book lodging months ahead.

Great
Fall (Sep-Oct)

Larch trees turn gold in the high country - Montana's unique fall color. Crowds thin dramatically after Labor Day. Going-to-the-Sun Road typically closes mid-October. Wildlife is active preparing for winter.

Mixed
Spring (May-Jun)

Snow lingers at high elevations. Going-to-the-Sun Road opening date varies year to year (typically mid-June to early July). Lower elevations are accessible and green. Bear activity increases as they emerge from hibernation.

Cold
Winter (Nov-Apr)

Montana winters are genuinely harsh - temperatures can drop to -30°F. Going-to-the-Sun Road is closed. But Big Sky and Whitefish offer excellent skiing. Yellowstone's north entrance remains open for winter wildlife viewing.

Local Knowledge

Montana Road Trip Tips

Big Sky Country demands big preparation.

Bear Country

Montana is grizzly bear territory. Carry bear spray on every hike (available for purchase or rental at park entrances). Make noise on trails, store food in bear-proof containers, and never approach a bear. This is not optional advice - it is survival protocol.

Going-to-the-Sun Reservations

Glacier National Park requires vehicle reservations for Going-to-the-Sun Road corridor from late May through mid-September (6 AM - 3 PM). Book through recreation.gov - they release 60 days and 1 day in advance. No reservation needed before 6 AM.

Vehicle Size Limits

Going-to-the-Sun Road prohibits vehicles over 21 feet long or 8 feet wide (including mirrors). No trailers allowed on the full road. This means no large RVs. Free shuttle buses operate within the park.

Gas & Services

Montana is big and empty. Between towns, gas stations can be 100+ miles apart, especially on US 2 and along the Hi-Line. Fill up in every town. Cell service is nonexistent in most of Glacier and the surrounding wilderness.

Speed Limits & Distances

Interstate speed limit is 80 mph, but distances are vast. Billings to Glacier is 450 miles (6+ hours). Plan for full driving days between regions. Montana had no daytime speed limit until 1999 - the culture still drives fast.

No Sales Tax

Montana has no sales tax, making it one of the most affordable states for gear, fuel, and dining. Prices are as marked everywhere.

Wildfire Season

August and September can bring wildfire smoke that obscures mountain views. Check AirNow.gov and InciWeb for fire conditions. Some years are pristine; others have weeks of haze.

Beartooth Highway Season

The Beartooth Highway (US 212) opens late May and closes by mid-October, weather permitting. Snow can close the road at any time. Check Montana DOT road conditions before attempting the drive.

Highlights

Top Stops in Montana

Glacier, Yellowstone, and the wild places between.

National Park

Glacier National Park

The Crown of the Continent. Over 700 miles of trails, 130+ named lakes, and 25 remaining glaciers (down from 150 in 1850). Going-to-the-Sun Road is the centerpiece, but Many Glacier and Two Medicine are equally remarkable.

Scenic Drive

Going-to-the-Sun Road

50 miles of road carved into the side of mountains, crossing the Continental Divide at Logan Pass. The engineering took 11 years (1921-1932). Vehicle size limits apply - no vehicles over 21 feet or 8 feet wide.

Scenic Byway

Beartooth Highway

A 69-mile stretch reaching nearly 11,000 feet. Alpine tundra, glacial lakes visible from the road, and snow-capped peaks in every direction. One of only a handful of roads in the US that reach above treeline for extended stretches.

Glacier NP Region

Many Glacier

The Swiss Alps of North America. Grinnell Glacier Trail is the signature hike - 11 miles roundtrip to an active glacier with a turquoise meltwater lake. Grizzly bear sightings are common along this trail.

Lake

Flathead Lake

The largest natural freshwater lake west of the Mississippi. The water is so clear you can see the bottom at 30+ feet. Cherry orchards line the east shore - pick your own in July. Glacier water feeds it, keeping it pristine.

Mountain Town

Whitefish

A charming ski town that's equally appealing in summer. Craft breweries, a walkable downtown, and the gateway to Glacier's west side. The Whitefish Trail system offers top-tier mountain biking.

National Monument

Little Bighorn Battlefield

The site of Custer's Last Stand in 1876. The battlefield is remarkably well-preserved, with markers showing where soldiers fell. A powerful, somber experience that tells both sides of the story.

National Park

Yellowstone (Montana Entrance)

Montana has three Yellowstone entrances. The north entrance (Gardiner) is open year-round. The Lamar Valley, accessible from the northeast entrance, is the best place in the lower 48 to see wolves in the wild.
