The short answer
A flexible three- or four-day Glacier plan built around the west side, Going-to-the-Sun Road, and one east-side day — with the official checks to make first.
- Day 1: west side — Apgar and Lake McDonald.
- Day 2: Going-to-the-Sun Road toward Logan Pass, once NPS reports it open.
- Day 3: an east-side valley such as Many Glacier or Two Medicine.
- Day 4 (optional): a slower lake day back in the Flathead Valley.
- Check NPS for road status and any vehicle-reservation rules before each day.

Before you build the days
Glacier's high country is typically reachable for only part of the summer. The full length of Going-to-the-Sun Road usually opens sometime in late June or July, depending on snow and plowing, and the National Park Service publishes the current status on its road page. Treat any itinerary — including this one — as a draft until you have checked that page.
In recent summers the park has used vehicle reservations for some entrances and corridors. The rules, dates and booking windows have changed from year to year, so read the current NPS reservation page and Recreation.gov before you lock in which day goes where.
Distances inside the park are longer in time than they look on a map. Rather than trusting a number from us, open the Google Maps directions links below from your own starting point on the day you go, and expect slower travel in peak summer and in construction zones.
Day 1: Apgar, Lake McDonald and the west entrance
Start gently on the west side. Apgar Village sits at the foot of Lake McDonald, the park's largest lake, and is the natural first stop: visitor information, the lakeshore, and an easy sense of scale before the bigger days.
Lake McDonald's shoreline is good for an unhurried afternoon. If your group includes young children or older relatives, this day can stand on its own; not everyone needs to do the high-road day.
A west-side day is also the best fallback when the upper road is not yet open or weather closes it.
Day 2: Going-to-the-Sun Road and Logan Pass
Going-to-the-Sun Road crosses the Continental Divide at Logan Pass and is the drive most visitors come for. Go early: parking at Logan Pass has filled quickly on summer days in past seasons.
Vehicle size limits apply on the road's alpine section. NPS has long restricted vehicles longer than 21 feet, wider than 8 feet including mirrors, or taller than 10 feet between Avalanche Creek and the Rising Sun area — check the current NPS page if anyone is bringing a large vehicle or trailer.
In seasons when the park runs its shuttle along the road, it can take pressure off parking. Service dates and stops vary, so confirm them on the NPS site.
Pick one or two trails rather than trying to stop everywhere. Ranger-posted trail status matters here: closures for wildlife or snow are common and are posted on the official conditions page.
Day 3: an east-side valley
The east side feels different: drier, windier and more open. Many Glacier and Two Medicine are separate valleys reached from the east, each with its own lakes and trailheads. St. Mary sits at the east end of Going-to-the-Sun Road.
From the Flathead Valley this is the longest day of the trip. Check the reservation rules for the specific valley you plan to visit, and look at the route in Google Maps before deciding whether to go over the pass or around it.
Day 4: give the group a slower day
A fourth day works best as a recovery day. Flathead Lake's public state park units, Bigfork, Kalispell and Whitefish all make easy alternatives, and they keep the trip from becoming three long drives in a row.
It is also the day to use the house. Trailstead's two Montana homes are built for groups coming back tired: The Tamarack in Lakeside and The Evergreen in Somers both have a hot tub and a sauna, plus a game room and fire pit for the evening.
Where to stay for this itinerary
A Flathead Valley base trades a shorter drive to the park entrance for space, kitchens and lake access through public sites. Neither Trailstead home includes private, deeded or direct lake access, a boat, dock or slip.
The Tamarack (Lakeside) and The Evergreen (Somers) each have six bedrooms. Guest limits, dates and the full stay total are confirmed on each home's own booking page.
| Day | Area | Best for | Check first |
|---|---|---|---|
| 1 | Apgar and Lake McDonald | Easy start, all ages | NPS conditions |
| 2 | Going-to-the-Sun Road and Logan Pass | The signature drive | Road status, vehicle reservations, size limits |
| 3 | Many Glacier, Two Medicine or St. Mary | East-side lakes and trails | Entry rules for that valley |
| 4 | Flathead Lake and valley towns | A slower group day | Weather and lake conditions |
