Glacier and Yellowstone Road Trip: A 9-Day Montana Route

Overview

This is the signature Montana road trip. You spend the first half in the northwest corner of the state working through Glacier National Park, and the second half in the south exploring Yellowstone's geothermal features, the Lamar Valley, and the Grand Canyon of the Yellowstone River. The drive from Whitefish to Gardiner (Yellowstone's North Entrance on US-89) covers roughly 380 miles and 6 to 7 hours, depending on your route south through the Mission Valley. The corridor between the two parks is worth slowing down for, not skipping.

The cleanest routing flies you into Glacier Park International Airport (FCA) in Kalispell on Day 1 and out of Bozeman Yellowstone International Airport (BZN) on Day 9. One-way car rentals between FCA and BZN are standard practice for this trip, though you should expect a drop fee ranging from $100 to $300 depending on the rental company. Booking your car in early spring is smart; Montana sees serious summer demand and economy class vehicles sell out at smaller airports by March. See the Montana Travel Guide for broader trip-planning resources on airports, packing, and budgeting.

Both parks charge separate vehicle entry fees (around $35 per vehicle, current estimate). An America the Beautiful annual pass (around $80) covers both parks plus every other federal recreation site and pays for itself in one stop. Buy it before you leave home through store.usgs.gov or at either park entrance. For a broader look at Montana's national parks and how to approach them, the National Parks overview covers logistics, seasonal timing, and what to prioritize.

Day 1: Arrive in Whitefish

Fly into FCA and drive the 15 miles into Whitefish on US-2 west, then US-93 north. The drive takes about 20 minutes. Whitefish sits at the base of Whitefish Mountain Resort and is the best full-service base for Glacier's west side. The drive from downtown Whitefish to the park's Apgar Visitor Center at the West Entrance runs about 30 minutes. Use this first afternoon to stock up: pick up bear spray at a local outfitter (carrying it is standard practice in grizzly country and smart anywhere in the park), buy groceries for trail lunches, and confirm your vehicle reservation for Going-to-the-Sun Road if you haven't already. Summer hotel rates in Whitefish run roughly $150 to $300 per night (estimate).

Day 2: Going-to-the-Sun Road

Going-to-the-Sun Road is 50 miles of pavement that climbs from the west shore of Lake McDonald up and over the Continental Divide at Logan Pass (6,646 feet), then descends to the St. Mary Valley on the east side. It is the only road crossing Glacier's alpine spine and the one stretch of driving that most visitors come to the park specifically to do. The road typically opens in full in late June or early July after snowplows clear avalanche debris from the high passes. Plan 5 to 6 hours for the round trip from Apgar, with stops at Lake McDonald Lodge, Avalanche Creek, The Loop, and Logan Pass. At Logan Pass, the Hidden Lake Overlook Trail (2.7 miles round trip, roughly 540 feet of gain) is the best short hike for the payoff: you end up above a high cirque with bighorn sheep on the scree.

Vehicle reservations are required for the Logan Pass corridor between 6 AM and 3 PM during peak summer. These go on sale in January through recreation.gov and sell out within hours. If you miss the reservation window, driving in after 3 PM is a real alternative: the west-facing cliffs above the road pick up warm afternoon light, and traffic thins out noticeably. For a full breakdown of how to structure your days inside the park, the Glacier National Park Itinerary covers the full west-to-east corridor, the best hikes by trailhead, and how long to budget for each section.

Day 3: Many Glacier

Drive the northern corridor to Many Glacier. From Apgar on the west side, the quickest route is back out the West Entrance, east on US-2 to Browning, then north on US-89 to Babb and west into the park. Plan about 2 hours door to door. The Many Glacier area occupies the Swiftcurrent Valley in the park's northeast interior and offers the most concentrated high-country terrain accessible by road. The Grinnell Glacier Trail (11.6 miles round trip, 1,600 feet of elevation gain) is a serious day hike that ends at one of the park's few remaining glaciers you can walk up to. The shorter Grinnell Lake Trail (7.6 miles round trip) is a good alternative. Grizzlies frequent this valley; make noise on the trail and keep bear spray accessible, not buried in your pack. If you're planning to stay in-park, Many Glacier Hotel on Swiftcurrent Lake books out 6 to 12 months ahead for summer nights.

Day 4: Drive South Along Flathead Lake

Leave Glacier Country today and start moving south. Drive US-93 south from Whitefish through Polson and along the west shore of Flathead Lake. Flathead is the largest natural freshwater lake west of the Mississippi, stretching 28 miles long and 15 miles wide through the Mission Valley. The drive along the west shore is 27 miles of water views, orchard country, and the Mission Mountains rising to the east. If your trip falls between mid-July and early August, this is cherry season: Flathead cherries are a regional product grown in the orchards between Polson and Bigfork, and roadside stands sell them by the flat.

Continue south to Missoula for the night. Whitefish to Missoula runs about 130 miles and 2.5 hours on US-93. Missoula sits where five valleys converge and the Clark Fork River runs through downtown. It's a college town with good restaurants, breweries, and enough character to be more than just a fuel stop. Hotels along Reserve Street run $100 to $180 per night (estimate).

Day 5: Missoula to Bozeman

From Missoula, take I-90 east to Bozeman. The drive is 200 miles and runs about 3 hours straight through. If you have a few extra hours, detour south from Three Forks on US-287 and stop at Lewis and Clark Caverns State Park in the Jefferson River canyon, between Whitehall and Three Forks. It's Montana's oldest and most visited state park, with guided tours through one of the largest limestone cavern systems in the Northwest. Tours run roughly May through September and last about 2 hours; plan an extra 1.5 to 2 hours in your day for the detour. Bozeman is the best-connected base for the next two nights: good hotels, the BZN airport nearby if schedules shift, and a fast 90-minute drive to Gardiner (Yellowstone's North Entrance). Summer lodging in Bozeman runs $180 to $350 per night (estimate).

Day 6: Bozeman and Paradise Valley

Spend the morning at the Museum of the Rockies on South Sixth Avenue in Bozeman. It houses one of the largest collections of dinosaur fossils in North America, including a Tyrannosaurus rex skull found in eastern Montana's Hell Creek Formation. The collections on Montana's prehistoric and Indigenous history are genuinely good and worth 2 to 3 hours.

In the afternoon, drive US-89 south through Paradise Valley, a 50-mile corridor along the Yellowstone River between Livingston and Gardiner. The Absaroka Range fills the eastern horizon, and the river runs alongside the road for much of the stretch. Stop at Yankee Jim Canyon, where the highway narrows to a shelf between cliff and current. At Gardiner (the town, not the park entrance), walk through the Roosevelt Arch at the park's original North Entrance gate. Theodore Roosevelt laid its cornerstone in 1903, and the inscription reads: 'For the Benefit and Enjoyment of the People.' Gardiner has independent motels and small lodges at $120 to $250 per night (estimate) as an alternative to Bozeman if you want to be closer to the park on Day 7.

Day 7: Enter Yellowstone, Mammoth and Lamar Valley

Drive into Yellowstone through the North Entrance at Gardiner. This is the only park entrance that stays open to cars year-round. The road climbs 5 miles from the arch to Mammoth Hot Springs, where the main terraces of travertine sit above the visitor center. Spend an hour on the Mammoth terraces in the morning, then drive east on the Grand Loop Road toward Tower-Roosevelt Junction, about 18 miles.

From Tower-Roosevelt, continue east into the Lamar Valley. The valley is a wide, grass-floored basin running roughly 10 miles east of the junction, flanked by rounded hills and cut by the Lamar River. It holds the highest concentration of wolves in the lower 48 states and draws dedicated wildlife watchers from all over the world. The pull-offs on the north side of the road between Slough Creek and the Lamar River bridge are the best vantage points. The windows for wolf sightings are dawn to about 9 AM and again from 5 PM until dark; midday is when they rest and disappear into the terrain. Bring binoculars, or plan to be standing next to someone with a spotting scope.

Day 8: Old Faithful and the Upper Geyser Basin

Drive the Grand Loop Road south and west from Mammoth. Stop at Norris Geyser Basin (23 miles from Mammoth), the hottest and most chemically acidic thermal area in the park. Norris is less crowded than Old Faithful and its features shift measurably from year to year. Continue south and west to Old Faithful, about 44 miles from Mammoth total via the loop. The geyser erupts roughly every 94 minutes on average; the visitor center posts a predicted time about 20 minutes in advance, accurate to within 10 minutes. The Upper Geyser Basin boardwalk surrounding Old Faithful is about 1.5 miles and passes a dozen other active geysers including Castle and Riverside. Plan to spend the full afternoon here.

This road trip works well for families planning their first big Montana visit. For an itinerary structured around kids' ages and pacing, see the Montana Family Itinerary, which covers both parks plus shorter hiking options and family-friendly lodging picks.

Day 9: Grand Canyon of the Yellowstone, Fly Out

Drive north from Old Faithful to Canyon Village, about 40 miles on the Grand Loop. Walk the canyon rim trails to the Upper Falls and Lower Falls viewpoints. The Lower Falls of the Yellowstone River drops 308 feet into a yellow-walled canyon, nearly twice the height of Niagara Falls. The walls got their color from hydrothermal activity that chemically altered the rhyolite rock over thousands of years. The short Artist Point trail on the south rim gives the classic view looking straight up the canyon.

After the canyon, exit the park toward Gardiner and drive west to Livingston, then south on I-90 to BZN (about 2 hours from Gardiner to the airport). Alternatively, exit via the West Entrance at West Yellowstone and drive north on US-191 through Big Sky to BZN, also about 2 hours. The West Yellowstone exit is slightly faster if you're based on the southern loop and catching an early flight.

Where to Stay

Whitefish is the base for Days 1 through 3. It has hotels, motels, and short-term rentals at varying price points; summer rates run roughly $150 to $300 per night (estimate). If you want to sleep inside Glacier, Many Glacier Hotel (on Swiftcurrent Lake) and Lake McDonald Lodge both book through Glacier's official concessioner and fill up fast. Apgar Campground at the West Entrance runs around $20 to $30 per night (estimate) and is first-come, first-served for some sites.

Missoula serves as a comfortable midpoint overnight on Day 4. Bozeman covers Days 5 and 6. Inside Yellowstone, Old Faithful Inn is the best-positioned property in the park for evening walks and early-morning eruptions; it books through Xanterra (Yellowstone's in-park concessioner) starting 13 months in advance. Canyon Lodge and Mammoth Hot Springs Hotel are solid backups. Gardiner and West Yellowstone both have independent motels at $120 to $250 per night (estimate) as outside-the-park alternatives for Day 7 or 8.

Book These Ahead

Going-to-the-Sun Road vehicle reservations for the Logan Pass corridor open in January each year at recreation.gov. They sell out within hours, so set a calendar reminder for the release date. Glacier in-park lodging (Many Glacier Hotel, Lake McDonald Lodge) opens reservations through the official concessioner the prior year; check glaciernationalparklodges.com. Yellowstone in-park lodging through Xanterra typically opens 13 months in advance at yellowstonenationalparklodges.com. Book a rental car from FCA by March if your trip is July or August. The America the Beautiful annual pass is available online at store.usgs.gov or at either park entrance.
