Montana Summer Road Trips

Why Montana in Summer

Montana summers are made for driving. From June through September, the state enjoys long daylight hours, comfortable temperatures between 70–85°F, and dry road conditions across nearly every corridor. Alpine passes that spend half the year buried under snow finally open, wildflowers carpet high meadows, and the rivers run clear after spring runoff subsides. Summer is the only season when every scenic route in the state is accessible — making it the ideal time to plan an extended road trip through Big Sky Country.

Beartooth Highway

Often called the most beautiful drive in America, the Beartooth Highway climbs through alpine tundra to a summit elevation of 10,947 feet. The road features dramatic switchbacks, glacial lakes tucked into granite bowls, and wide-open views of the Absaroka-Beartooth Wilderness that stretch to the horizon.

Paradise Valley & Yellowstone

US-89 from Livingston to Gardiner follows the Yellowstone River through a broad valley framed by the Absaroka Range and the Gallatin Range. This is classic Montana ranch country — hay fields, fly fishing access points, and the warm mineral waters at Chico Hot Springs. The route ends at Yellowstone's North Entrance, the only park gate open year-round.

Glacier Park East Side

The eastern approach to Glacier National Park follows US-2 and US-89 along the Rocky Mountain Front, where the Great Plains collide with the Continental Divide in a wall of limestone cliffs. In summer, Going-to-the-Sun Road opens for one of the most spectacular drives in North America — 50 miles across Logan Pass with views of hanging glaciers, weeping waterfalls, and alpine meadows.

Seeley-Swan Corridor

MT-83 threads through the Clearwater and Swan valleys between the Mission Mountains and the Swan Range. In summer, this corridor is all about lake swimming, berry picking along forest roads, and quiet campgrounds tucked among old-growth larch and cedar.

Flathead Lake Loop

Circle Montana's largest natural freshwater lake on a route that passes cherry orchards, state parks, tribal heritage sites, and dozens of boat launches. The west shore (MT-35) is quieter and more scenic; the east shore (US-93) offers faster travel and access toPolson and Bigfork.

Skalkaho Highway

This gravel mountain pass connects the Bitterroot Valley to the Philipsburg area through the Sapphire Mountains. The highlight is Skalkaho Falls, a powerful cascade that crashes right next to the narrow roadway. High-clearance vehicles are recommended, and the route is not suitable for large RVs or trailers.

Pioneer Mountains Scenic Byway

This 49-mile paved backcountry route between Wise River and Dillon passes through the Beaverhead-Deerlodge National Forest. Highlights include Crystal Park (dig your own quartz crystals), the Coolidge ghost town, and wide alpine meadows surrounded by the rugged Pioneer range.

Summer Road Trip Tips

• Check road conditions before heading out — even in summer, mountain passes can close temporarily for construction or rockslides. Use 511mt.net for real-time updates.
• Carry bear spray and know how to use it. Both grizzly and black bears are active throughout Montana's backcountry in summer.
• Book lodging early. Small-town motels and campgrounds near Glacier and Yellowstone fill up weeks in advance during July and August.
• Watch for wildlife at dawn and dusk. Deer, elk, and moose frequently cross Montana highways — especially on corridors near rivers and valleys.
• Fuel up in every town. Gas stations can be 80–100 miles apart on some backroad routes. Never pass a pump with less than half a tank.
• Bring layers. Mountain pass summits can be 30°F cooler than valley floors, even in July.
• Carry a physical map. Cell service is unreliable or nonexistent on many scenic corridors.
