Weather in Glacier National Park in May
May in Glacier is a transitional month when winter slowly gives way to spring. While lower elevations begin to see blooming wildflowers and budding trees, higher elevations remain snow-covered well into late May. The weather can be unpredictable, with a mix of sunny days, rain showers, and occasional late-season snowstorms.
- Early May – Highs in the mid-40s°F, with overnight lows often dipping below freezing. Snow is still common at higher elevations, and trails can be muddy or icy.
- Late May – Highs in the 50s and occasionally into the low 60s°F, with milder nights. Lower-elevation areas become more accessible, but mountain passes remain buried under deep snow.
Spring rain is frequent, and temperatures can vary widely, so packing layers is essential. For a more detailed breakdown of year-round weather in Glacier, check out this guide: Glacier National Park Weather by Season.
How to Pack for May in Glacier
Pack layers—you’ll see everything from sunshine to sleet in one day.
- Clothing: Waterproof jacket, fleece layers, moisture-wicking base layers.
- Footwear: Waterproof hiking boots with good traction for snow and mud.
- Accessories: Gloves, a hat, sunglasses, and sunscreen (yes, even in May—glacier reflections can be intense!).
What's Open in Glacier National Park in May?
Road Access & Seasonal Openings
Glaciers start to wake up in May, but access is still limited. Many roads, lodges, and services are in the process of opening, but rest assured, you'll find what you need during your visit. It's important to know what will be available, and we're here to guide you through it.
- Going-to-the-Sun Road In May: Plowing begins in April, but full road access typically doesn't happen until late June. Portions near Lake McDonald and St. Mary may be open for vehicle access. However, it is the perfect time of year to travel Going-to-the-Sun Road on an e-bike, beginning at Lake McDonald Lodge or the Avalanche Lake Trailhead (depending on road status).
- Many Glacier: Snow may still block roads early in May, but accessibility improves later.
- Two Medicine & St. Mary: Some areas are open, but expect limited services. Again, bikes from St. Mary up toward Jackson Overlook can be epic this time of year!
- North Fork (Polebridge, Bowman, Kintla): Roads are rough and may still be muddy or snow-covered. It is an excellent time of year to visit the Polebridge Mercantile and hike in the lower regions in and around the park, but expect minimal access to Bowman or Kintla.
Lodging & Services Available in May
You’ll need to plan ahead—most park lodges and services don’t open until June. However, there are still options both inside and outside the park.
- Lodges & Hotels: Most Glacier National Park lodges, including Many Glacier Hotel, Lake McDonald Lodge, and the Swiftcurrent Motor Inn, remain closed until mid to late June. However, the Village Inn at Apgar sometimes opens in late May, and a few accommodations in the St. Mary area may be available. Most visitors will book their stay in the nearby towns of Whitefish, Kalispell, or Columbia Falls when visiting in May.
- Campgrounds: Apgar Campground, the park's most significant, is typically open on a first-come, first-served basis in May. St. Mary Campground sometimes opens for reservations later in the month. Still, Many Glacier and other high-elevation campgrounds usually remain closed due to lingering snow.
- Dining Options: Food services inside the park are extremely limited in May. Most lodges with restaurants won't open until June, so you must bring your food or dine in nearby towns like Whitefish, Columbia Falls, or St. Mary. Apgar Village may have limited snack and grocery options.
- Visitor Centers & Services: The Apgar Visitor Center is open in May with limited hours, offering ranger information, restrooms, and park maps. St. Mary Visitor Center typically opens later in the month. At the same time, the Logan Pass Visitor Center remains closed until the Going-to-the-Sun Road fully opens in the summer.
- Cabins & Vacation Rentals: For a cozy and private stay, consider booking a cabin or vacation rental in West Glacier, Columbia Falls, or near St. Mary. These options often provide kitchen facilities, allowing you to prepare meals since dining options inside the park are limited in May.
Best Things to Do in Glacier National Park in May
May in Glacier National Park offers a mix of adventure and relaxation, with opportunities to explore lower-elevation trails, spot wildlife, and take in breathtaking scenery without the summer crowds. While some areas remain snow-covered or inaccessible, plenty of activities remain to enjoy, from hiking and photography to early-season water adventures.
Rafting & Scenic Floats
May is exciting to hit the water in and around Glacier National Park, but conditions vary depending on the activity. Whitewater rafting is at its peak, with snowmelt swelling the Middle and North Forks of the Flathead River, creating fast, high-volume rapids. If you're looking for an adrenaline rush, guided rafting trips with outfitters in West Glacier offer thrilling Class II-III (and sometimes Class IV) rapids this time of year.
For a more relaxed experience, scenic float trips provide a calmer way to enjoy the park's incredible scenery. These guided floats, typically offered on the Middle Fork of the Flathead River, let you enjoy Glacier's rugged mountain views while drifting through peaceful stretches of water.
Fishing In May
Fishing can be challenging in May due to high water levels and fast currents caused by spring runoff. While some calmer backwaters or lakes may be fishable, most rivers are murky and difficult to wade. If fishing is a priority, consider waiting until late June when water levels drop, or try casting in Lake McDonald or Two Medicine Lake for better conditions. Check out our Ultimate Guide to Fishing in Glacier for more information.

Wildlife Viewing in May In Glacier Park
May is one of the best times to see wildlife—bears, moose, and elk move down from the snowline to feed in the valleys. With fewer crowds and lush spring landscapes, it's a great time to observe these creatures in their natural habitat.
Common Sightings
Grizzly and black bears are highly active, often seen foraging along roadsides and meadows. Moose frequent marshy areas, while mountain goats and bighorn sheep navigate rocky cliffs. Elk herds are common in open valleys, and migratory birds return to the park's lakes and wetlands.
Best Areas for Wildlife
- Many Glacier: Bears are frequently spotted near the road and on trails like Grinnell Valley and Red Rock Falls. Watch for moose near Fishercap Lake.
- North Fork: A remote area with excellent chances to see wolves, bears, and deer along Inside North Fork Road and near Bowman and Kintla Lakes.
- Two Medicine: An excellent place for spotting bears and mountain goats, especially around the lake and near Appistoki Falls.
Safety Tips
Carry bear spray and know how to use it. Stay at least 100 yards from bears and 25 yards from other wildlife. Avoid surprising animals by making noise while hiking. Always observe from a distance.
