How We Picked
Montana has thousands of miles of highway, but not all of them earn a detour. We selected these seven routes by looking at three things: distinct terrain that changes as you drive, reliable conditions for a standard rental car, and a clear payoff at the end or along the way. Every drive here is paved, open to passenger vehicles, and worth slowing down for. Whether you're filling in a first-timer's Montana travel guide or adding another leg to a return trip, this list covers the drives that consistently deliver.
Going-to-the-Sun Road
Going-to-the-Sun Road crosses Glacier National Park end to end, running 50 miles from West Glacier on the west side to St. Mary on the east. The road climbs to Logan Pass at 6,646 feet, with sheer cliff walls on one side and open air on the other for miles at a stretch. It's the centerpiece of Glacier Country and one of the most technically engineered mountain roads in North America. The full road usually opens in late June or early July after snowplow crews clear avalanche debris that can stack 80 feet deep near the Weeping Wall section.
Vehicle size limits apply to the central section between Avalanche Creek and the Sun Point parking area: nothing over 21 feet total length (tow vehicle included) or 8 feet wide. Timed vehicle reservations are required in peak summer for the Logan Pass corridor, so book through recreation.gov as soon as reservations open each spring. One detail most first-timers miss: Logan Pass parking fills by 7 or 8 a.m. on summer mornings. Arrive before sunrise or take the free park shuttle from Apgar on the west side or St. Mary on the east.
Beartooth Highway (US-212)
US-212 runs 68 miles from Red Lodge southwest to Cooke City along the Montana-Wyoming border, and for most of that distance it climbs and twists across the Beartooth Plateau, topping out at 10,947 feet at Beartooth Pass. The alpine plateau is genuinely different from anything else in Montana: tundra, glacier-carved lakes, and snow patches that persist through July. Red Lodge sits about 60 miles south of Billings on US-212, and Cooke City sits at the Northeast Entrance to Yellowstone, so this highway doubles as one of the most dramatic approaches to the park you can make.
The Beartooth typically opens in late May and closes with the first heavy snowstorm of autumn, which can arrive as early as September. If you're planning a fall run, check road conditions through the Montana DOT before you commit. The Top of the World Store near the Wyoming state line is the only fuel stop on the route and a natural place to pull over and look back at the plateau you just crossed.
Paradise Valley (US-89)
The 55-mile drive south from Livingston to Gardiner on US-89 follows the Yellowstone River through the wide valley between the Absaroka Range on the east and the Gallatin Range on the west. This is ranch and river country, and the Yellowstone is visible from the road for most of the drive, running clear green through cottonwood-lined banks. Drift boats work the river throughout summer, which gives the drive a particular feel in July and August: equal parts mountain scenery and active fishing culture.
If you're coming from Bozeman (about 45 miles east of Livingston via I-90), Paradise Valley is the most rewarding approach to Gardiner and Yellowstone's North Entrance, adding only about 20 minutes compared to the faster highway. Pull off at the Carbella Recreation Area, roughly 30 miles south of Livingston, for good river access and a place to stretch. Gardiner is the only year-round auto entrance to Yellowstone, so this drive also works in winter when other park roads are closed to vehicles.
Gallatin Canyon (US-191)
US-191 heads south from Bozeman about 90 miles to West Yellowstone, cutting through the Gallatin Canyon for the bulk of the route. The Gallatin River runs alongside the road the entire way through the canyon, dropping through Class II and III rapids you can watch from the shoulder. Big Sky Resort is about 45 miles from Bozeman, and the ski mountain above it is visible from several pull-offs along the drive south. In summer the canyon road carries significant traffic toward Yellowstone, so midweek driving is noticeably calmer than weekends.
If you're doing this drive in summer and want to extend it, the Gallatin connects directly to Yellowstone's West Entrance, making it a natural through-route for anyone basing in Bozeman who wants to hit the park without backtracking. The stretch between Big Sky and West Yellowstone is particularly open and fast.
Swan Valley (MT-83)
MT-83 runs about 60 miles from Bigfork and Swan Lake south through the Swan Valley to Seeley Lake, with the Bob Marshall Wilderness to the east and the Mission Mountains Wilderness to the west. This is one of Montana's less-driven corridors, partly because it doesn't link two high-traffic destinations directly. Swan Lake is calm and clear, with the Mission Mountains reflected in the water on still mornings, and it ranks among the best lakes in Montana for kayaking and early-morning photography. The valley is a recognized wildlife corridor: moose, osprey, and black bears are reliably spotted near the lake in summer.
About halfway through the valley, watch for the Lindbergh Lake Road turnoff near mile 70 heading south. The 4-mile unpaved spur leads to Lindbergh Lake, a high-country lake beneath the Mission Mountains with no services and very little traffic. A standard passenger car handles it fine in dry conditions, just expect some washboard gravel.
Bitterroot Valley (US-93)
US-93 runs 75 miles south from Missoula through the Bitterroot Valley to Darby, with the Bitterroot Range rising on the west and the Sapphire Mountains on the east. The Bitterroot River parallels the highway through most of the valley and several public fishing access sites are signed along the route. Stevensville, about 28 miles south of Missoula, is worth a stop: it's home to St. Mary's Mission, established by Jesuit missionaries in 1841 and considered Montana's oldest continuously occupied settlement. The mission buildings are open for summer tours and give a concrete anchor to the Lewis and Clark and fur-trade history running through this valley.
The drive is more relaxed than the high-mountain options on this list, but the Bitterroot Range tops out near 10,000 feet and the scale of the peaks grows as you move south toward Darby. Hamilton, about 45 miles south of Missoula, is the practical midpoint for fuel and food.
Rocky Mountain Front (US-89 North)
The stretch of US-89 from Choteau north through Dupuyer to Browning shows you something specific to north-central Montana: a mountain range rising nearly 4,000 feet above flat grain and grass prairie in less than 5 horizontal miles. The Rocky Mountain Front is the abrupt eastern edge of the Rockies, and from the highway the scale takes a moment to register. The drive from Choteau to St. Mary on Glacier's east side covers about 85 miles and pairs well as an approach from Great Falls (GTF), about 50 miles east of Choteau on US-89.
This corridor holds some of the highest grizzly bear densities outside Glacier and Yellowstone, and raptors, pronghorn, and elk are common roadside sightings throughout the year. For a deeper breakdown of what wildlife to expect and where to stop, the guide to the best places to see wildlife in Montana covers this corridor and others across the state in detail.
Quick Comparison
Going-to-the-Sun Road has the highest drama per mile but requires the most planning: reservations, vehicle size restrictions, and early starts. The Beartooth Highway has more altitude and fewer crowds but a tight seasonal window from late May to early fall. Paradise Valley and the Gallatin Canyon are the easiest to work into a Bozeman or Yellowstone itinerary without committing a full day to driving. The Swan Valley and Bitterroot Valley are lower-key and better suited to travelers who want scenery without traffic. The Rocky Mountain Front is the right call if you're routing through Great Falls or want to arrive at Glacier from the east with a view of the landscape that few visitors see. For lodging near any of these drives, browse hotels and lodges by region to find options close to each route.
Frequently asked questions
When is the best time of year to drive these scenic routes in Montana?
Most of these drives are fully open from late June through September. Going-to-the-Sun Road usually opens in late June or early July and closes with the first hard snowstorm in October. The Beartooth Highway opens in late May and can close as early as September. Paradise Valley, the Gallatin Canyon, the Swan Valley, and the Bitterroot are accessible year-round under normal conditions, though mountain weather can create icy roads from November through March. The Rocky Mountain Front roads along US-89 are generally open year-round.
Do I need reservations or permits to drive these roads?
Going-to-the-Sun Road requires a timed vehicle reservation for the Logan Pass corridor during peak summer, typically late May through early September. Reservations open through recreation.gov each spring and sell out quickly. Glacier National Park also charges an entrance fee (around $35 per vehicle as of 2025; check nps.gov for current rates). No other drive on this list requires a permit for a standard passenger vehicle. The Beartooth Highway is a public US highway with no entrance fee.
Can I drive these routes in a standard rental car?
Yes, every drive on this list is paved and accessible in a standard passenger car under normal conditions. The Gallatin Canyon, Paradise Valley, and Bitterroot Valley drives are the most straightforward. Going-to-the-Sun Road has sharp switchbacks on the west side near the Loop section, but rental cars handle them without issue. The one hard restriction: vehicles over 21 feet long (tow vehicle included) or over 8 feet wide cannot drive the central section of Going-to-the-Sun Road. Park at Apgar or St. Mary and take the free park shuttle instead.
Which Montana scenic drive is best for wildlife viewing?
The Rocky Mountain Front corridor along US-89 north of Choteau has high grizzly bear, elk, and pronghorn densities, particularly in the shoulder seasons. The Swan Valley on MT-83 is reliable for moose and osprey near Swan Lake in July and August. Paradise Valley along US-89 south of Livingston sees bald eagles along the Yellowstone River in winter and pronghorn on the open flats in summer. Going-to-the-Sun Road gives access to mountain goats and bighorn sheep around Logan Pass from July into September.
