The Complete Glacier National Park Guide: Montana's Crown of the Continent
Glacier National Park is a million acres of the Northern Rockies that makes you understand why the phrase "America's Best Idea" gets attached to the national park system. The going-to-the-Sun Road alone — an 80km engineering marvel crossing the Continental Divide at 2,026 meters — justifies the trip. The glaciers, the wildlife, and the turquoise alpine lakes are bonuses that most destinations would kill to have as their main attraction.
Overview
Located in northwestern Montana, Glacier shares a border (and ecosystem) with Canada's Waterton Lakes National Park. Together they form the Waterton-Glacier International Peace Park. The landscape: towering peaks carved by ancient glaciers, U-shaped valleys, and over 700 miles of hiking trails.
The park has 25 named glaciers remaining, down from 150 in 1850. Climate scientists estimate most will be gone by 2030. This is not alarmism — it's measurement.
Best Time to Visit
Mid-July to mid-September: Going-to-the-Sun Road is fully open. Wildflowers peak in late July. Trails are clear of snow. This is also the busiest period.
June: Lower elevations accessible. The road may be partially open. Fewer crowds but more snow on high trails.
September to mid-October: Larches turn gold in late September. Cooler temperatures. Many facilities close but the park is gorgeous.
Getting There
Fly into Glacier Park International Airport (FCA) in Kalispell, 30 minutes from the West Entrance. Or Missoula (MIS), 2.5 hours south. Amtrak's Empire Builder stops at West Glacier and East Glacier.
You need a car. There's no practical way to explore the park without one.
Where to Stay
In the park: Many Glacier Hotel (from $250/night, book 6-12 months ahead), Lake McDonald Lodge (similar), Glacier Park Lodge at East Glacier. Campgrounds: $10-23/night.
Outside the park: Whitefish (40 min, charming ski town, from $120/night), Columbia Falls (cheapest options), St. Mary (east side, from $100/night).

The mountains don't care about your schedule
Glacier is not a casual park. It demands planning, respect, and early mornings. In return, it delivers landscapes that remind you the continent was here long before anyone built roads through it.
For the east side border connection, Banff is an 8-hour drive through stunning Canadian Rockies.
