So You’re Headed to Glacier… But It’s Only May or June
If you’re planning a trip to Glacier National Park in early season—let’s say May or June—first of all: good for you. When it comes to a First-Timer’s Guide: Visiting Glacier National in Early Season, remember to pack layers, a backup plan, and a good sense of humor.
Early season in Glacier runs from mid-May through late June. And while that might sound like the beginning of summer, up here in northwest Montana, it’s still very much a shoulder season—especially at higher elevations.

1. The Reality Check: Snowstorms Are Still a Thing
Let’s clear up a common misconception: June is not peak season. In fact, it’s often still winter at Logan Pass. Yes, seriously. You might be wearing a tank top in West Glacier and dodging snowdrifts just 20 miles up the road.
The iconic Going-to-the-Sun Road (GTTSR) is rarely fully open before the last week of June or even early July, depending on snowpack and late spring storms. Parts of the road will be open—usually from West Glacier to Avalanche Creek—but don’t expect full access unless you’re visiting closer to the 4th of July.
First Timer’s Guide: What to Do in Glacier National Park When Going-to-the-Sun Road Is Closed
So You Booked a Glacier Trip… and the Road Is Closed. Now What? You booked your dream trip to Glacier National Park. Lodging? Check. Park pass? Check. Hiking playlist and matching flannel? Obviously.…
Keep reading2. What Is Open in May and June?
Plenty! You just have to know where to look.
Lower elevation hikes and activities are where it’s at in early season. Some favorites include:
- Avalanche Lake Trail – Open early and almost always hikeable by June.
- Lake McDonald – Paddleboarding, kayaking, or just soaking in those reflective views.
- Trail of the Cedars – A wheelchair- and stroller-accessible loop through an old-growth forest.
- Many Glacier – Typically opens in mid-June (check road status). Great for moose-spotting, but quite a drive a way from West Glacier.
Bonus: fewer crowds, more wildlife sightings, and a front-row seat to spring’s dramatic comeback.
3. What to Pack for Glacier in Early Season
You need more than flip-flops and a hoodie.
Here’s your quick packing checklist for May/June:
- Waterproof hiking boots (trails can be muddy or slushy)
- Warm layers: fleece, thermal shirts, a good puffy jacket
- Rain jacket or shell – mountain weather changes fast
- Gloves and hat (you’ll thank me)
- Traction cleats or poles if you’re heading to icy trails
- Sunscreen & sunglasses – the snow glare is real
- Daypack with extra snacks and dry socks
4. Be Flexible—Your Itinerary Might Change
Glacier doesn’t care that you booked your trip six months ago. Sometimes the park throws you a curveball: road closures, bear activity, surprise snowstorms, or all three in one day.
Stay updated with the official park alerts, and consider having backup plans for each day—like visiting Whitefish, checking out Flathead Lake, or booking a last-minute boat tour on Lake McDonald.
5. Final Thoughts: Why Early Season Is Still Worth It
Sure, you might not drive the entire GTTSR or summit Hidden Lake Overlook in early June—but you’ll experience a quieter, more peaceful version of Glacier. Fewer crowds, dramatic mountain snowcaps, and wildlife on the move make early season unforgettable.
If you’re a flexible traveler who can roll with a little weather chaos, early season might just be the best-kept secret in Glacier.
