Spring at Glacier is a lower-elevation experience. Going-to-the-Sun Road remains closed mid-mountain — typically until late June. The west side (Lake McDonald, Apgar) opens earlier and serves as your hub. Spring brings bear emergence, snowmelt-fed waterfalls, and the first wildflowers in McDonald Valley. Most campgrounds are still closed in early spring; Apgar opens by mid-May. The trade-off is solitude: in May, you may have Lake McDonald nearly to yourself. Prepare for cold nights and possible snow on any May day. Trails above 6,000 ft remain snow-covered.

What's special now
Highlights this season
Lake McDonald in solitude
Drive the 10-mile west-shore road in May for empty pullouts and reflective glacial waters. Park your rig at Apgar Village.
Avalanche Lake hike
5-mile round-trip, accessible from Avalanche Creek trailhead once snow clears (typically late May). One of the most photogenic lakes in the park.
McDonald Falls + Sacred Dancing Cascade
Both waterfalls run their loudest in May. Short, family-friendly walks.
Bear watching from the west
Grizzlies emerge from dens in April-May. They favor the lower elevations on the west side. Drive slowly, scan meadows.
Apgar Village amenities
Campground, boat rentals, visitor center, lodge. The west-side hub when half the park is still snowed in.
Time it right
When to go
Best window to plan
Late May is the practical earliest — Apgar Campground opens, Avalanche Creek trail clears, weather warms. Earlier spring requires accepting that most of the park is inaccessible.

Safety considerations
- Bears emerging from hibernation are unpredictable. Carry bear spray.
- Snowmelt creeks run fast and cold. Don't ford on foot.
- Trails may still have icy patches at higher elevations.
- Avalanche risk in late spring backcountry — consult ranger station.
- Cell service is poor inside the park.
No surprises

Glacier has implemented vehicle reservations during peak windows in recent years. Check the current year's policy on the NPS website.
What wildlife emerges in spring at Glacier?
Grizzly and black bears emerge from hibernation in April-May. Bighorn sheep and mountain goats become visible. Wildflowers peak in lower meadows late May.
What the NPS site won't tell you
The NPS doesn't advertise this: in early May, the road from Apgar past Lake McDonald to Avalanche Creek can be biked or hiked before it opens to vehicles. Locals call it 'silent season.' Bring a fat bike or e-bike — you'll have 10 miles of paved road essentially to yourself.
