A glacier national park memorial day weekend trip is a different park than the one on the postcards. In late May the snowmelt is at full roar, the valleys are green, the crowds have not arrived yet, and the bears and bighorn are back on the lower slopes. The trade-off is the one fact everyone needs to plan around: the high country is still under snow.
The key thing to know: Going-to-the-Sun Road is usually NOT fully open over Memorial Day weekend. It typically opens all the way to Logan Pass in mid-to-late June. In late May, crews have usually plowed only the lower sections, the west side from Apgar and Lake McDonald up to about Avalanche, and a short stretch on the east St. Mary side. Logan Pass itself is closed and snowbound. Always check the official road status before you drive.
So this 3-day route is built around what is actually accessible and what late May does best: Lake McDonald and Apgar, the Trail of the Cedars and Avalanche Lake when the road is open that far, lower McDonald Creek and Sacred Dancing Cascade, the waterfalls of Two Medicine and Running Eagle Falls, the lower trails and falls of Many Glacier, and St. Mary Lake with Sun Point and Baring Falls. Note that several in-park lodges and some facilities do not open until early-to-mid June, and bears are active in spring, so carry bear spray and make noise on the trail.

Most in-park lodges run by the park concessioner, including Lake McDonald Lodge and Many Glacier Hotel, do not open until early-to-mid June, so they are usually not an option over Memorial Day weekend. Plan to base outside the park in Whitefish, West Glacier, or Kalispell on the west side, or St. Mary or East Glacier on the east side. Fly into Glacier Park International (FCA) near Kalispell. Always check Going-to-the-Sun Road status on nps.gov before you go, because how far the road is plowed changes year to year.
Start on the west side, the part of the park most reliably open over Memorial Day weekend. From West Glacier, drive into Apgar Village at the foot of Lake McDonald, the largest lake in the park, where the colorful pebble beach and the long view up to the still-snowy peaks is one of the great photo stops in the Rockies. If the seasonal boat tour is running, an hour on the water is the easy way to take in the scale of it.
Then follow Going-to-the-Sun Road as far as it is plowed, usually to Avalanche in late May. Walk the flat Trail of the Cedars loop through old-growth forest, then continue on the Avalanche Lake trail (about 5.9 miles round trip when the road is open that far) to a glacial lake fed by a fan of waterfalls that are at their loudest with the spring melt. Check the road status first, because in some years the gate is still below Avalanche and the trail starts farther down.
Spend the morning on the lower stretches of McDonald Creek, where the spring melt turns the river into a series of churning chutes. Stop at the Sacred Dancing Cascade and the McDonald Falls overlook, both short walks off the lower Going-to-the-Sun Road, before the snow line forces you to turn back. This is late May at its best: huge water, green forest, and almost no one around.
In the afternoon, drive around the south end of the park (Logan Pass is closed, so you cannot cut across the top) to the St. Mary side. The east entrance road opens a short way along St. Mary Lake in late May. Walk out to Sun Point for the classic view down the lake to Wild Goose Island, and continue on the easy trail to Baring Falls. Base for the night in St. Mary or East Glacier so you are close to Two Medicine and Many Glacier tomorrow.
Start at Two Medicine, the quiet southeast corner of the park that sees a fraction of the crowds. Walk the short trail to Running Eagle Falls (about 0.6 miles round trip), also called Trick Falls because in high water it pours over the top and out of a cave at once, exactly the kind of show late-May snowmelt puts on. Then take in Two Medicine Lake, ringed by snow-dusted peaks, with the boat dock and easy lakeshore strolls.
Finish at Many Glacier, often called the heart of the park. The Many Glacier road usually opens by late May, though the hotel does not open until June. The high trails are still buried in snow, but the lower ones are walkable: hike to Apikuni Falls (about 2 miles round trip) for a roaring snowmelt cascade, and walk the lower Grinnell-area trails along Swiftcurrent Lake for the big amphitheater of peaks. On the way between valleys, pull off at the Goat Lick Overlook on US 2, where mountain goats come down to the mineral cliffs in spring.

Over Memorial Day weekend Going-to-the-Sun Road is usually plowed only to Avalanche on the west side and a short way on the St. Mary side, with Logan Pass still closed. How far it is open changes year to year, so check the official status page before each day and build your plan around the gate.
You are trading the alpine high country for roaring snowmelt waterfalls, green valleys, returning wildlife, and a fraction of the summer crowds. Lean into the lower trails and the falls. The big alpine hikes simply are not in season yet.
Lake McDonald Lodge, Many Glacier Hotel, and most concessioner lodging do not open until early-to-mid June. Plan to base outside the park in Whitefish, West Glacier, or Kalispell on the west, or St. Mary or East Glacier on the east.
Spring brings bears down into the green valleys, right where the open lower trails are. Carry bear spray where you can reach it, make noise around blind corners and rushing water, and never hike with earbuds in. Give wildlife plenty of room.
With Logan Pass closed, getting between the west and east sides means driving around the south end of the park on US 2, roughly a two-hour transfer. Plan your days so you are not crossing back and forth, and base on the side you will spend the most time on.
Trails that climb, like Grinnell Glacier, Iceberg Lake, or anything near Logan Pass, are still buried in snow and often unsafe over Memorial Day weekend. Stick to valley and lakeshore trails and short waterfall walks, and pack waterproof boots and layers.
