Glacier National Park in Early October
I've been to Montana before, but always on the Yellowstone side. This time, my friend and I flew into Kalispell with a group of girls for four days based out of Whitefish to see Glacier National Park for the first time, and I was not prepared for how stunning it would be. Here's everything we did, what I'd do differently, and exactly what you need to know if you're planning this same trip in early October.
Why Early October Changes Everything
Going-to-the-Sun Road, the main road connecting the west and east sides of the park, closes for the season sometime in fall, and can close earlier than expected due to snow. We hit this firsthand: it was closed the morning we tried to drive through to Many Glacier, which meant a full reroute. If you're going in early October, check the NPS road status page daily in the weeks before your trip, and build a backup plan into your itinerary the way we accidentally did.
Early October also means fewer crowds and a haunting kind of quiet in the park. Down in the valley (Whitefish, West Glacier, Lake McDonald), expect highs in the 40s and lows in the high 20s/low 30s. Up at elevation, think Many Glacier and anywhere near Grinnell, it runs noticeably colder, easily into the teens and low 20s, especially early morning and at the summit. We felt this firsthand: freezing getting ready at Many Glacier Hotel, and even colder once we reached the top of the Grinnell trail. Pack like it's late fall, not early fall.
Day 1: Arrive & Settle In
Fly into Kalispell, pick up your rental car, and head to Whitefish. We rented bear spray right at the airport. Do this immediately, don't wait.
That evening, we stopped at The Lodge at Whitefish Lake, right on the water. They let us sit outside by the fire pits to watch the sunset, and it was one of the best decisions of the trip. Don't skip this.

Day 2: Avalanche Lake (and a Road Closure Lesson)
The plan was Many Glacier first, to hike Grinnell Glacier. We were up at 5am and on the road, but Going-to-the-Sun Road was closed, blocking the route through. Lesson: always have a plan B for this park in shoulder season.
We pivoted to Avalanche Lake:
We hiked it in the dark, which was nerve-racking. This is well-known grizzly territory, and hiking before sunrise means visibility is low right when animals are most active. We were a big group, so we split bear spray between every 3 people, kept it accessible, and made noise. At one point close to the trail we heard a heavy thumping sound that really sounded like a grizzly. We stopped, made noise, and it moved off. We never saw it, but it's the kind of moment that snaps you into how real that risk is. We reached the lake right as the sun came up, genuinely one of the best moments of the trip.
From there we added the Trail of the Cedars loop and spent time at Lake McDonald and McDonald Falls. We never got to see the full stretch of Going-to-the-Sun Road since it was closed past a certain point, worth a return trip just for that drive. That evening we'd hoped to get into Abbruzzo, but couldn't snag a reservation, so we ended up at an Indian restaurant a bit further out instead. It was really good, no regrets.
Day 3: Grinnell Glacier
This is the big one, and worth every bit of planning.
We got ready at Many Glacier Hotel and it was brutally cold. We had on every layer we packed, and we could barely move to get geared up. We started anyway, shed layers as we warmed up on the trail, and then got hit with cold again at the top, easily the coldest point of the whole trip. This is where microspikes mattered. Icy patches near the glacier made traction a real factor, not just a "nice to have." The view of the glacier at the top was completely worth it.

What We'd Do Differently
Glacier completely changed how I think about Montana. If you've only done the Yellowstone side, this is your sign to go north. Just go in with a real plan for road closures, cold, and gear, and this trip will blow you away the same way it did us.
