One road, two seasons, and a record instead of a date
Going-to-the-Sun Road is really two roads. The lower stretches at each end, along Lake McDonald on the west and up from St. Mary on the east, are open much of the year. The alpine section between them, the climb over Logan Pass at 6,646 feet, is buried all winter and opens for a season that has never once started on the same date twice. When people ask when the road opens, they are asking about that middle piece, and the only honest answer anyone can give in November is the record: the park has written down every opening since 1933, and planning against ninety seasons of evidence beats planning against a rumor.
The second moving part is how you are allowed to use the road once it opens, and that has changed three summers in a row. In 2024 and 2025 you needed a vehicle reservation to drive in from the west in the middle of the day. In 2026 the reservations were dropped entirely, and the experiment moved to Logan Pass itself: a ticketed shuttle and a three hour parking limit. For 2027 the park has published nothing, no opening projection, no reservation system, no shuttle plan, no parking rule. This page keeps the distinction bright: what ran last season is printed as last season's, and what has not been announced is labeled exactly that.
The live word on any given morning is the park itself: the current conditions page and the road status linked from it outrank anything written here, and the planner below will tell you which of its calls to recheck there.
The tracker
The road today, piece by piece
The 2026 season is over and the road is in its winter posture. Here is every piece of it as the park's own notices describe it now.
| Piece | State today | What it means |
|---|---|---|
| The alpine section, Avalanche Creek to Jackson Glacier Overlook | Closed for the season | The park's seasonal closure is in effect. Logan Pass is not reachable by car from either side, and there is no through route across the park. |
| The west side below the gate | Open to Avalanche Creek, on winter terms | Apgar and Lake McDonald are reachable. The park's warning stands all winter: open stretches can close at any time for weather. |
| The east side below the gate | Open to Jackson Glacier Overlook, on winter terms | The lower St. Mary side is reachable up to the overlook; the same winter warning applies. |
| Logan Pass | Closed for the season | The visitor center closed after September 27, 2026 and the water is off. Nothing is staffed up there until the road reopens. |
| The Logan Pass shuttle and timed parking | Ended September 7, 2026 | The 2026 pilot is finished. Whether either piece returns is part of the 2027 plan the park has not published. |
| Spring plowing | Starts at the beginning of April, on the park's pattern | Crews open the Sun Road from both ends toward the pass. While they work, the closed sections open to hikers and bikers whenever crews are off the road, as far as the posted crew closures allow, which makes late spring the one season you can walk or ride the empty road. |
| The 2027 opening date | Not yet announced | The park projects an opening only when plowing is well along, usually weeks before the day itself. Until then, the record further down this page is the planning tool. |
| The 2027 access rules | Not yet announced | No reservation system, shuttle plan or parking rule for 2027 has been published. Anyone selling you certainty about them today is guessing. |
The park can also close pieces of the road inside the season, and did twice in 2026: three days in September for rain and rockfall risk, and again from October 9 when the fall storms arrived. An open road on this page always means open as last reported, never guaranteed.
Bookable now
Three ways to have the day anyway
The pass is closed and next season's rules are unwritten, but a Glacier trip is not on hold. These are the bookable pieces that do not depend on the alpine section, plus the one to buy for the day the road is yours. The planner below points back to the right one for your month.
Guided winter day · Book on Viator
Lake McDonald and Apgar in the quiet season, driven by a local
A small group winter day on the lower west side: Lake McDonald and its historic lodge, Apgar Village, the Belton Bridge, with park admission, a picnic lunch and the winter driving all handled. This is the guided answer for every month the pass is under snow.

The Middle Fork of the Flathead, along the park's southern boundary
A guide rows, you watch the park go by: a gentle half day on the river that forms Glacier's southern border. It runs on the river's season, not the road's, which makes it the bookable day for the trips the record warns about: May and early June before the opening, and the fall after the closing.

A narrated co-pilot for the drive itself
For the day the record says is yours: GPS-triggered narration for the full fifty miles, the pullouts named before you reach them and the stories behind them. Two honest notes from the listing itself: it is rated 4.1, not perfect, and it must be downloaded over Wi-Fi before you go, because there is no signal on the road to fetch it with. It never expires, so buying it during the winter planning months costs nothing in shelf life.

The trip planner: your month against the record
Three answers in, and the planner reads your trip the way the record supports: what the road is most likely to be doing in your month, what the access position is, and what to book now versus what to simply watch for. It will not invent a 2027 rule. Where the park has not announced, the plan says so and plans around the silence.
The planner works from the park's published opening record and the last announced access system, both printed in full below. It knows nothing about next spring's snowpack, and neither does anyone else yet; the plan tells you when the park's own projection usually lands so you can hold the right decisions open until it does.
The season just ended
How 2026 ran, start to finish
The full road opened on June 22, 2026, with Logan Pass reachable from both entrances and lingering snow on the trails at the top. The season's access story was the experiment at the pass. There were no vehicle reservations anywhere in the park, the first summer of this decade without them, and in their place the park piloted two things from July 1 to September 7:
- A ticketed Logan Pass shuttle. Every rider age two and up needed a ticket, sold only on Recreation.gov at a $1 processing fee, for a named boarding point and time: Apgar Visitor Center and Lake McDonald Lodge on the west side, Rising Sun Picnic Area and St. Mary Visitor Center on the east. Early express runs left from 6 a.m. for hikers. Tickets came out in two windows, a portion sixty days ahead starting May 2 at 8 a.m. Mountain Time, and the rest each evening at 7 p.m. for the next day. On most days the shuttle and standby lines moved well, by the park's own end-of-season account. One gap worth knowing: Avalanche Lake and the Trail of the Cedars were not on the shuttle's route in 2026.
- Three hour timed parking at Logan Pass. You parked first, then took a free timestamped permit from the kiosk and put it on the dashboard; three hours was the limit, enforced around the clock. The lot holds 235 spaces, and the park issued 1,200 to 1,300 permits on most days, which is the experiment's real result: the same small lot served several times its usual number of parties.
Both programs ended after Labor Day, September 7, and parking went back to first come, first served for the rest of the season. The road itself had two weather interruptions, a pattern worth planning for in any year: a proactive closure from the evening of September 6 to September 9 for heavy rain and rockfall risk, and a storm closure from October 9 that ran into the seasonal shutdown, on the park's standing pattern of closing the pass for winter on the third Monday of October when weather allows. The park published no closing date for 2026, as it has not for any fall since 2022.
Why this section exists: the system has now changed three summers running, reservations in 2024, different reservations in 2025, none in 2026, and the pilot's strong numbers make some version of it a live candidate for 2027 without making it a fact. Book next summer's refundable pieces early, hold the nonrefundable ones, and treat the park's announcement, when it comes, as the start of the real planning season.
The evidence
The opening record, 2010 to 2026
The park's own record of Logan Pass openings runs back to 1933, the summer the road was dedicated. The middle opening across that whole record falls in mid June. The extremes frame every plan: the earliest opening ever was May 16, 1987, and the latest was July 15, 1933; in the modern era the late years are the July 13 openings of 2011, 2020 and 2022. The recent record is the part your trip actually draws from, and its shape is blunt: in the last twenty seasons, no opening came before June 13, half the seasons were open by June 22, and fourteen of twenty were open by July 2.
| Year | Opened | Closed | The season's note |
|---|---|---|---|
| 2026 | June 22 | October, seasonal closure | No vehicle reservations; the Logan Pass shuttle and timed parking pilot ran July 1 to September 7. The park published no closing date. |
| 2025 | June 16 | Not in the park's published record | Timed entry reservations on the west side and the North Fork, 7 a.m. to 3 p.m., June 13 to September 28. |
| 2024 | June 22 | Not in the park's published record | Vehicle reservations from the west side only, 6 a.m. to 3 p.m. through September 8; none from the east. |
| 2023 | June 13 | Not in the park's published record | The earliest opening since 2005, which is what an easy winter buys. |
| 2022 | July 13 | October 16 | An exceptional avalanche year, per the park's record; the west side closed October 1 for road work, with the pass reachable from the east to October 16. |
| 2021 | June 25 | October 13 | |
| 2020 | July 13 | October 9 | The pandemic season: the road ran from the west entrance to Rising Sun, and a portion stayed closed all season for the first time in the road's history. |
| 2019 | June 22 | September 25 | |
| 2018 | June 22 | September 29 | |
| 2017 | June 28 | September 3 | The west side closed early for the Sprague Fire and road work; the pass stayed reachable from the east to October 9. |
| 2016 | June 16 | October 10 | |
| 2015 | June 19 | October 5 | The west side reached Logan Pass on June 10; the full road followed on June 19. The east side closed October 5 for road work, the west holding to October 19. |
| 2014 | July 2 | September 22 | The east side closed September 22 for road work; the pass stayed reachable from the west to October 20. |
| 2013 | June 21 | September 23 | The east side opened to the pass on June 15, the west side a week later; the fall closing was the federal government shutdown. |
| 2012 | June 19 | September 16 | The west side closed September 16 for road rehabilitation; the pass stayed reachable from the east to October 15. |
| 2011 | July 13 | September 17 | An exceptional snowpack year with winter weather through June. The west side closed September 17 for road work; the pass stayed reachable from the east to October 17. |
| 2010 | June 24 | October 18 |
Openings and closings through 2022 are the park's published Logan Pass record; the 2023 to 2026 openings are the park's season-opening announcements. The park has published no closing dates since 2022, and the table says so rather than borrowing a date from anywhere else. The full record back to 1933 is on the park's Logan Pass opening and closing dates page.
The standing rule
The 21 foot rule, and what to do with a bigger rig
One rule does not change with the seasons or the access system, because it is geometry, not policy. Between Avalanche Creek and Rising Sun, the road is closed to any vehicle or combination longer than 21 feet including bumpers, or wider than 8 feet including mirrors. Vehicles over 10 feet tall may have difficulty west of Logan Pass to The Loop, where the rock overhangs come down to meet the road. Most full-size trucks and every RV with a trailer are outside that envelope, by design: the alpine section was built in the early 1930s, to the width of the cars of the time.
- The partial drives that stay open to you: stock trucks and trailers can reach Packers Roost on the west side and Siyeh Bend on the east, the two ends of the restricted stretch.
- The way around: US-2 along the park's southern boundary, through East Glacier Park and up to St. Mary, roughly two to two and a half hours between West Glacier and St. Mary. It is a good road and a real drive, not a punishment.
- The way over: in season, the park shuttle and the guided tours run vehicles that fit the road, which is the entire reason several of the bookable options above exist. If your rig cannot cross, riding over with someone whose vehicle can is not a compromise; it is the standard solution, and it has the side benefit of a driver who is not watching the drop.
The rest of the park
Glacier does not close when the pass does
The lower roads carry a park of their own. On the west side, Lake McDonald is ten miles of cold, clear water under the Continental Divide, Apgar Village sits at its foot, and the road up to Avalanche Creek passes Lake McDonald Lodge and the trailheads for the Trail of the Cedars and Avalanche Lake, two of the most walked trails in the park. On the east side, the road climbs from St. Mary to Jackson Glacier Overlook, where the glacier it names is visible across the valley. Many Glacier, the park's hiking capital, and the Two Medicine valley both run on their own roads and their own seasons, entirely independent of Logan Pass.
Named without links, because we only link what we can stand behind with a booking route: the boat tours on Many Glacier's two lakes, Two Medicine Lake, St. Mary Lake and Lake McDonald are run by the Glacier Park Boat Company, take reservations about a year ahead on the company's own site, and start selling out in spring; the historic red bus tours and the Blackfeet-run Sun Tours book through the park's concession channels and are the classic way over the road without driving it. Lodging we leave to you: West Glacier and Apgar put you at the west gate, St. Mary at the east, and nothing on this page earns anything from where you sleep.
Sources and small print
How this page is kept honest
The current road state is the park's seasonal closure notice, in effect now. The 2026 season's dates and system are from the National Park Service's season opening release of June 2026, its Vehicle Reservations in 2026 page, its Visiting Logan Pass in 2026 page, and its September 8, 2026 update on the shuttle system and Logan Pass parking. The 2024 and 2025 systems are from those seasons' opening releases. The opening and closing record is the park's published Logan Pass table, extended with its 2023 to 2026 opening announcements. The vehicle limits are quoted from the June 2026 opening release. Where the park has not announced, the page prints Not yet announced, and where the park has stopped publishing, the page says that too.
