Seattle to Glacier National Park covers roughly 840 miles via US-2 East and US-89 North, with a total drive time of 13–15 hours spread across 4–5 days. This is the best summer road trip in the Pacific Northwest–Northern Rockies corridor: diverse terrain, manageable daily legs, and a world-class park at the finish. The route follows the Great Northern Railway corridor across the Cascades, drops into eastern Washington, cuts through the Idaho Panhandle, and climbs into Montana’s Flathead Valley before delivering you to one of the most dramatic mountain landscapes in the lower 48.
Quick Facts
- Total distance: ~840 miles
- Total drive time: 13–15 hours (driving only)
- Recommended trip length: 4–5 days
- Best season: Mid-June through mid-September
- Number of stops: 6 (plus start)

Who This Route Is For
- Ideal for families who want a structured itinerary with towns, lodging, and restaurants every 2–3 hours.
- Good for sedans and standard SUVs; Going-to-the-Sun Road inside Glacier has a vehicle length limit of 21 feet (including tow vehicles), so large RVs and trailers cannot drive the full road — plan accordingly.
- Great for first-time Glacier visitors coming from the Seattle metro who want context and scenery before the park, not just a flyover flight.
- Not recommended for anyone with an inflexible 3-day window — Glacier alone warrants a full two days minimum in summer.
Seattle, WA — Start Here
Fuel up before leaving the city. Gas prices east of the Cascades drop noticeably, but you won’t find a better selection of provisions than in Seattle’s eastern suburbs (Bellevue, Issaquah, North Bend). Stock a cooler; the US-2 corridor through the Cascades has limited services between Skykomish and Leavenworth.
Leavenworth, WA (2.5 hours from Seattle via US-2 East)
Leavenworth sits at the eastern foot of Stevens Pass and makes an ideal first overnight or lunch stop. The Bavarian-themed main street is a bit kitschy, but the surrounding Wenatchee National Forest is legitimately impressive. Eat at South, a solid contemporary American restaurant on Front Street, before pushing east. Fill your tank here — it’s the last reliably cheap gas before Spokane.
US-2 between Stevens Pass and Leavenworth is a two-lane mountain highway with tight curves and steep grades. In mid-June 2026, watch for rockfall debris on the road from spring snowmelt runoff; WSDOT typically clears slides by early June but conditions can linger.
Spokane, WA (2.5 hours from Leavenworth via US-2 East)
Spokane is the largest city on the route and the right place to handle logistics: grocery runs, an oil check, car wash, and a proper dinner. Downtown Spokane’s Kendall Yards neighborhood has good dining; Frank’s Diner on Second Avenue is a genuine 1906 dining car serving breakfast all day and is worth the stop. Spokane also has multiple fuel stations near I-90 if you’re topping off before the Idaho leg.
Sandpoint, ID (1.5 hours from Spokane via US-2 East / ID-200)
Sandpoint on Lake Pend Oreille is the surprise of the trip. The lake is enormous — 43 miles long — and the downtown is walkable with independent coffee shops and a good bookstore. From Spokane, take US-2 east into Idaho and follow ID-200 along the lake’s southern shore. This is a scenic 30-minute detour that costs nothing in extra time if you’re stopping for lunch anyway. Sandpoint is also the last major grocery stop before Montana’s more rural stretches.
Missoula, MT (2 hours from Sandpoint via US-2 East)
Cross into Montana on US-2, which merges briefly with I-90 near Alberton before reaching Missoula. This is a natural overnight stop: a university town with strong food and craft beer options. For a quick, filling meal, the Top Hat Lounge on West Front Street does reliable burgers and live music most evenings. Missoula is also where you should download the Glacier National Park vehicle reservation system confirmation if you haven’t already — timed-entry permits for Going-to-the-Sun Road are required in summer and sell out weeks in advance.

Flathead Lake, MT (1.5 hours from Missoula via US-93 North)
US-93 North out of Missoula runs directly up the Mission Valley with the Mission Mountains visible to the east. Flathead Lake — the largest natural freshwater lake west of the Mississippi — sits along the right side of the road for about 30 miles. Stop at one of the roadside cherry stands near Polson or Bigfork in mid-June (cherry season peaks here late June–July, so early-season visitors may catch the tail end of strawberries instead). Polson has a full-service gas station; fill up here before heading north toward Glacier.
Glacier National Park, MT (1.5 hours from Polson via US-93 North / US-2 East)
Enter the park at the West Glacier entrance on US-2. Going-to-the-Sun Road (the park’s iconic 50-mile transmountain road) typically fully opens by mid-to-late June, though the Logan Pass section (elevation 6,646 ft) can remain partially closed through the third week of June depending on snowpack. In 2026, check the NPS Glacier road conditions page before your arrival date — do not assume full access.
Plan at least two full days inside the park. The Logan Pass area, Avalanche Lake Trail (a 4.5-mile round trip), and the St. Mary Lake viewpoints are the non-negotiable stops. The Village Inn at Apgar and Glacier’s many campgrounds book out by March for summer dates; if you haven’t reserved, check for cancellations on Recreation.gov starting 60 days out.
FAQ
How long does it take to drive from Seattle to Glacier National Park?
The drive is approximately 840 miles and takes 13–15 hours of total driving time via US-2 East and US-93 North. Most drivers spread this over 4–5 days with overnight stops in Leavenworth, Spokane or Sandpoint, Missoula, and the Flathead Valley.
Is Going-to-the-Sun Road open in mid-June?
Going-to-the-Sun Road typically opens fully to vehicles by mid-to-late June, but Logan Pass can remain closed through the third week of June in heavy snow years. Always verify current status on the NPS Glacier National Park website before arrival; partial openings from each end are common in early June.
Do you need a reservation to drive through Glacier National Park in summer?
Yes. Glacier requires timed-entry vehicle reservations for Going-to-the-Sun Road between the Apgar and St. Mary entrance areas from late May through early September. Reservations open on Recreation.gov and sell out quickly — book as early as possible, typically several weeks in advance.
What is the best route from Seattle to Glacier — US-2 or I-90?
US-2 is the more scenic and direct northern option, passing through Stevens Pass, Leavenworth, and the Idaho Panhandle before reaching Montana. I-90 is faster but adds southern mileage through Ellensburg and Coeur d’Alene. For this itinerary, US-2 is the better choice by a significant margin.
Are there gas stations on US-2 between Seattle and Spokane?
Services are sparse between Skykomish and Leavenworth (roughly 60 miles). Fill up in Monroe or Index before heading into the mountains, and again in Leavenworth. East of Spokane, services become more regular through northern Idaho and into Montana.
Is US-2 safe to drive in June?
US-2 through Stevens Pass is generally safe in June, but rockfall and wet pavement are real hazards on the mountain sections in early summer. Drive the Cascades portion in daylight, watch for slow-moving logging trucks, and check WSDOT’s travel alerts before departure.
