Going-To-The-Sun Road Opening Dates: The Full Plowing Record
The alpine section of Going-to-the-Sun Road opens late and closes early, and the record shows exactly how much the window moves from year to year.
Short answer
Going-to-the-Sun Road's alpine section has opened between June 16 and July 13 over the recorded years, with 2026 opening on June 22. The road typically closes around the third Monday in October. The lower sections on both sides stay open earlier and later, and several guided and audio tours work even when Logan Pass is closed.
Glacier National Park's most famous 50 miles are also its most fragile. Going-to-the-Sun Road crosses the Continental Divide at Logan Pass, 6,646 feet up, and every winter the alpine section disappears under snow that takes crews months to remove. Plowing starts on April 1 in a typical year, and the full road does not open to motor vehicles until late June or, in bad years, the second week of July. That window shapes nearly every trip plan, because a visitor arriving in mid-June may find the west side open to Avalanche Creek and the east side open to Jackson Glacier Overlook, with the middle of the park still buried.
This guide lays out the verified record rather than a promise: the official National Park Service table of Logan Pass openings and closings, the 2026 season as it actually happened, and the practical question underneath it all, what you can still do when the pass is closed. The honest answer is that quite a lot remains bookable, from guided drives on the lower west side to self-guided audio tours that follow the road's history, and this site's own Glacier National Park Tour Packages roster covers the ones sold through live listings.
When Does Going-To-The-Sun Road Open Each Year?
Going-to-the-Sun Road's alpine section has opened anywhere between June 16 and July 13 across the years with a verified record, and 2026 opened on June 22. The lower west side opens to Lake McDonald Lodge much earlier, typically by late May, and the lower east side follows. The full 50 miles between West Glacier and St. Mary only run through when plow crews finish the alpine stretch.
The National Park Service maintains an official table of Logan Pass opening and closing dates, and it is the single best planning document for this road. Two facts jump out of it. First, the opening date swings across nearly a month from year to year, so a trip booked for the third week of June is a genuine gamble. Second, the closing date swings just as much, from mid-September in fire and avalanche years to mid-October in calm ones.
The 2026 season followed the pattern closely. Plow crews began work on April 1, reached the Big Drift, the final major snow obstacle, in mid-May after a relatively mild winter, and the park opened the entire 50-mile length to motor vehicles on June 22. Local press reported the opening the same day, and the Spokesman-Review confirmed it two days later. The National Park Service has not updated its own historical table past 2022, so the 2026 date carries press sourcing rather than an official table entry, which is worth knowing if you are comparing sources.
The road is a National Historic Landmark and a National Civil Engineering Landmark, completed in 1932 after 11 years of construction and formally dedicated on July 15, 1933. Its seasonal rhythm is not a design flaw. It is the direct consequence of building a highway across an alpine environment where the average snowpack settles to around 16 feet and snow can fall in any month.
What Does The Verified Opening And Closing Record Show?
The official record runs from 2009 to 2022 and shows openings from June 16 (2016) to July 13 (2011 and 2022), with closings from September 3 (2017) to October 19 (2009). The 2026 opening, June 22, sits near the middle of that spread. No verified dates exist for 2023 through 2025 in the official table.
The table below is the National Park Service's own record of when Logan Pass opened and closed to through traffic. It is the reason this guide exists: any claim about a "typical" opening week should be checked against these rows, not against a blog post that names a single date.
| Year | Logan Pass Opened | Logan Pass Closed |
|---|---|---|
| 2009 | June 26 | Oct 19 |
| 2010 | June 24 | Oct 18 |
| 2011 | July 13 | Sept 17 |
| 2012 | June 19 | Sept 16 |
| 2013 | June 21 | Sept 23 |
| 2014 | July 2 | Sept 22 |
| 2015 | June 19 | Oct 5 |
| 2016 | June 16 | Oct 10 |
| 2017 | June 28 | Sept 3 |
| 2018 | June 22 | Sept 29 |
| 2019 | June 22 | Sept 25 |
| 2020 | July 13 | Oct 9 |
| 2021 | June 25 | Oct 13 |
| 2022 | July 13 | Oct 16 |
The National Park Service footnotes explain the outliers. The 2011 and 2022 openings on July 13 came in exceptional snow and avalanche years. In 2020 the late opening was COVID-19 related, and for the first time in the park's history a portion of the road stayed closed for an entire season. The 2017 early closure was the Sprague Fire. Several other early closings were one-sided, caused by a multi-year road rehabilitation project rather than weather.
For planning purposes, the record supports three honest statements. Late June is a coin flip, with roughly half the recorded years open by June 25 and half not. Early July is close to a safe bet, with only the worst snow years running past July 2. And mid-July, the 13th, is the latest opening in the entire table, so a trip from July 14 onward has never in this record found the pass closed for the season, though temporary weather closures remain possible at any time.
If your dates fall before the likely opening, the tours in the selection below are the ones that still deliver a real park day. They reach parts of Glacier that do not depend on the alpine section, and one of them, the audio tour, simply waits for the road with you.
Which Tours Still Work When Logan Pass Is Closed?
When the alpine section is closed, the west side is open to Avalanche Creek and the east side to Jackson Glacier Overlook, so lower-road driving tours, rafting on the Middle Fork, guided walks, and the Lake McDonald area all remain fully available. Only tours that promise Logan Pass itself are affected, and operators reroute or refund those.
The practical geography is simple. The closure point on the west side is Avalanche Creek, about 16 paved miles in from West Glacier, and that stretch includes Apgar Village, Lake McDonald, and the Trail of the Cedars trailhead. On the east side, vehicles can typically reach Jackson Glacier Overlook from St. Mary. A visitor who arrives in mid-June has not lost the park. They have lost the middle of it, roughly 20 alpine miles, and gained smaller crowds on the sections that are open.
The bookable roster reflects that split. The West Side Driving Tour, 4.8 across 37 reviews, from $250 per person for six hours with lunch and hotel pickup included, runs Apgar Village and Lake McDonald, both below the closure point, and its listing explicitly notes it skips the Sun Road. It is a direct answer for the pre-opening weeks. The Going-to-the-Sun Road Audio Tour, 4 across 27 reviews, from $9.99 per group for up to 15 people, is the other side of the coin: it narrates the entire 50-mile road, all 27 confirmed stops from West Glacier through Logan Pass to Saint Mary, and it works whenever the road you are actually driving is open. Its 10 to 11 hour window matches a full-road day, and a group can run just the open sections and save the rest for a return trip, since the purchase is per group, not per day.
The guided walks and rafting trips sit entirely outside the road question. A four-hour Nature Walk in Glacier National Park, 4.9 across 127 reviews and from $70 per person, runs on west-side trails that do not require the pass. Half-day whitewater rafting on the Middle Fork of the Flathead, 4.9 across 1,959 reviews and from $55 per person, launches near West Glacier and never touches the road at all. If your trip lands in the plowing weeks, swapping a Logan Pass day for a river day is the most common and least painful adjustment.
The tours that genuinely cannot run are the ones the park itself restricts to the alpine corridor. Only Glacier National Park Lodges (the Red Bus fleet) and Sun Tours are authorized to conduct motor vehicle tours on Going-to-the-Sun Road between Lake McDonald Lodge and Rising Sun, and both operators state plainly that their full routes depend on access to the Logan Pass Visitor Center, with alternate routes provided when the road is closed. Our guide to Going-to-the-Sun Road tour options covers those concessioner tours in detail, including what happens to your booking when the pass closes early.
How Do You Check Whether The Road Is Open Today?
The National Park Service posts road status on its Glacier website and offers text alerts by texting GNPROADS to 333111, and live webcams show the Logan Pass parking lot and surrounding road in real time. Temporary closures happen even in high summer, most often for snow, fire, or congestion, so check the morning of your drive.
Seasonal opening is one question. Today's status is another. On September 14, 2026, for example, park officials temporarily closed the alpine section between Avalanche Creek and Jackson Glacier Overlook because of light snowfall at Logan Pass and cold temperatures, with snow levels dropping to 6,500 feet. That is a live event, not a season closure, and the road reopened. But it shows why a June or September traveler should never treat the opening date as a guarantee for any specific day.
The official tools are the ones to use. The park's road information page carries vehicle restrictions and current status, the Logan Pass access page explains the 2026 parking and shuttle pilots, and the text alert service pushes closure and reopening notices directly to your phone. The webcams, including multiple views of the Logan Pass lot, settle the "is it actually open right now" question faster than any phone call.
One 2026 detail worth knowing before you drive: the park did not require vehicle reservations anywhere this season, so no timed-entry booking stood between you and the road. That is a major change from the prior five years, and many third-party planning sites still describe the old system. What replaced it, a ticketed-only shuttle to Logan Pass from July 1 to September 7 and a three-hour parking limit at the pass lot over the same dates, is covered in our comparison of the park shuttle versus a guided tour.
How Late In The Season Is The Road Open?
The alpine section typically closes around the third Monday in October, weather permitting, though earlier closures happen. The verified record shows season closings as early as September 3 and as late as October 19. September travelers get the road almost to themselves, with 552,479 visits in September 2025 against 765,061 in July.
Fall is the road's second act. The closing side of the record is less discussed than the opening side, but it matters just as much for September and October trips. The pattern the park states is a closure around the third Monday in October, and the record backs that up in calm years. The exceptions are instructive: fire closed the road early in 2017, and the rehabilitation project closed one side at a time in several seasons.
September is the connoisseur's month, and the visitation numbers prove it. In 2025, July saw 765,061 recreation visits and August 718,766, while September dropped to 552,479 and October to 127,537. July and August alone were 47.3 percent of the entire year. A September visitor is trading peak-season certainty for roughly a quarter fewer people on the same road, with the added risk that an early snow event closes the pass for a day or two, exactly as happened on September 14, 2026.
The weather numbers explain the trade. West Glacier's September normals are a 68.0 degree average high and a 40.8 average low, with 1.96 inches of precipitation, and the National Park Service notes that Logan Pass runs 10 to 15 degrees cooler than West Glacier and that snow can fall at lower elevations as early as mid-September. The same source records that snow can fall in any month at the pass. Our month-by-month breakdown in Glacier National Park weather by month pairs these normals with what they mean for each section of the road.
| Month | Avg High (West Glacier) | Avg Low | Precip (in) | What It Means for the Road |
|---|---|---|---|---|
| May | 64.1 | 39.0 | 2.62 | Lower sections open, alpine still under plows |
| June | 70.4 | 45.1 | 3.80 | Opening month, record spans June 16 to July 13 |
| July | 80.2 | 49.6 | 1.39 | Fully open, peak visitation |
| August | 79.4 | 47.9 | 1.17 | Fully open, 718,766 visits in 2025 |
| September | 68.0 | 40.8 | 1.96 | Open, but temporary snow closures possible |
| October | 51.7 | 32.9 | 3.05 | Season closure typically third Monday |
For a September trip, the same tour logic applies in reverse. The audio tours and the west-side drive all still run, and the concessioner tours run through late September, with Red Bus west-side routes ending between September 12 and October 2 depending on the route and pickup point.
What Vehicle Rules Affect Driving The Road Yourself?
Vehicles longer than 21 feet including bumpers or wider than 8 feet including mirrors are prohibited between Avalanche Creek and Rising Sun, and vehicles over 10 feet tall may have difficulty on the westbound descent from Logan Pass to The Loop. The park itself names a guided tour or the shuttle as the answer for oversized vehicles.
This is the restriction that quietly converts a lot of self-drive plans into tour bookings. Rental RVs, most motorhomes, and many trucks with trailers simply cannot legally enter the alpine section, no matter how early the road opens. The National Park Service states the limits plainly on its road information page, and the rock overhangs on the west side add a height problem for taller vehicles even where length is legal.
The park's own Logan Pass FAQ makes the commercial connection explicit: visitors with oversized vehicles who want to reach the pass can secure a shuttle ticket or reserve a guided tour with an authorized commercial operator. That is the strongest honest argument for a tour on this entire road, independent of any listing. If your vehicle fits the limits, a self-guided audio tour in your own car covers the same 50 miles for a group price, and the two audio products on the roster take different approaches to it.
The Self-Guided Audio Driving Tour, 4.4 across 118 reviews, from $19.99 per group for up to 8 people, is a private full-day format covering Lake McDonald Lodge, Apgar Visitor Center, Logan Pass, Lunch Creek, Siyeh Bend, and Wild Goose Island among its confirmed stops. The Going-to-the-Sun Road Audio Tour at $9.99 per group for up to 15 is the cheaper, more stop-dense option with 27 confirmed points along the full road. Both carry free cancellation, and both are per group rather than per person, so the price basis matters when comparing: a family of five pays the same single group fee either way.
How Should You Plan A Trip Around The Opening Date?
Book lodging and in-park reservations for late June and beyond, treat anything before July 2 as conditional, and hold a fallback activity that does not need the pass. Entrance is $35 per private vehicle for seven days, no vehicle reservation is required, and 2026 shuttle tickets cost $1 per person through Recreation.gov.
The planning sequence that fits the record is straightforward. Choose your week using the opening table above, book the fixed items early, and keep the pass-dependent day flexible within your week rather than pinned to your arrival date. A traveler who arrives June 20 with a Logan Pass hike planned for June 21 has a coin-flip chance of disappointment. The same traveler who keeps two candidate days open and checks the road status each morning almost always gets the pass.
Money details for the 2026 rules: a private vehicle pays $35 for a seven-day entrance pass, $25 in winter from November 1 to April 30, and the Glacier annual pass is $70. Non-US residents aged 16 and over paid an additional $100 per person this season unless admitted with an annual pass, a surcharge new enough that most competitor pages do not carry it. The full fee structure, including the eight fee-free days for US citizens and residents, is broken down in our guide to Glacier National Park entrance fees and passes.
| Planning Item | What the Record Says to Do |
|---|---|
| Trip week before June 25 | Book lower-road activities, treat the pass as a bonus |
| Trip week June 25 to July 2 | Keep two flexible days for the pass, check status daily |
| Trip week July 14 onward | Every recorded year was open by July 13 |
| September trip | Road open, pack layers, expect possible day closures |
| Oversized vehicle | Take a guided tour or the ticketed shuttle, per NPS |
| Parking at Logan Pass | Three-hour limit applied July 1 to Sept 7, 2026 |
The fallback activities are not consolation prizes. A half-day scenic float on the Middle Fork, 4.9 across 851 reviews and from $55 per person, and a guided nature walk at from $70 per person are the two most common swaps, and both run through the shoulder season. Travelers weighing the whole question of driving versus being driven can go deeper in guided tour or drive yourself at Glacier.
What Happened In The 2026 Season?
The 2026 season opened in full on June 22 after plowing began April 1, ran a ticketed shuttle and three-hour Logan Pass parking pilot from July 1 to September 7, and saw a temporary snow closure of the alpine section on September 14. July 2026 was the fourth-busiest July on record at 896,386 visits, up 17.17 percent.
The 2026 season is a useful case study because every stage of it was documented. The mild 2025-2026 winter put plow crews at the Big Drift by mid-May. The full road opened June 22, within a day of the 2018 and 2019 openings. The park ran its two pilots, the reservation-only shuttle and the parking time limit, through Labor Day weekend, and local reporting credited the parking limits with helping manage the record July volume.
The winter damage was real but contained: roughly 135 feet of rock wall was swept away in the Slopes area, with temporary jersey barriers installed and permanent repairs scheduled later. The road stayed open through it. The September 14 snow closure, the same event that closed the Highline Trail and Hidden Lake Trail for a day, was the season's reminder that "open for the season" and "open today" are different claims.
The visitation pressure is the context for every opening-date question. July 2026 recorded 896,386 recreation visits, 17.17 percent above July 2025 and the fourth-busiest July on record, with year-to-date visitation through July at 1,823,478. More people on a road that opens late means the open weeks are compressed into a busier window, which is exactly why the record matters: knowing the odds lets you either pick a quieter week or book the guided and audio options that absorb the crowds for you.
For the road itself, the audio tour remains the most flexible way to experience all 50 miles whenever your dates land, narrating every confirmed stop from West Glacier to Saint Mary for one group price.
The three options below cover the full spread of what is bookable around this road, from the narrated drive to the west-side tour that never needs the pass.
Common Questions About Going-To-The-Sun Road Opening Dates
Is Going-To-The-Sun Road Open?
The alpine section opens between mid-June and mid-July in a typical year and closes around the third Monday in October. In 2026 the full road opened on June 22. Check the National Park Service road status page or text GNPROADS to 333111 for today's conditions, since temporary weather closures can happen in any month.
What Is The Earliest Going-To-The-Sun Road Has Opened?
The earliest verified full opening in the official record is June 16, 2016. The latest is July 13, in both 2011 and 2022, exceptional snow years. The 2026 opening on June 22 sits near the middle of the 2009 to 2022 record.
Can You Drive Going-To-The-Sun Road Before It Fully Opens?
Yes, on the lower sections. The west side typically opens to Avalanche Creek, including Apgar Village and Lake McDonald, and the east side to Jackson Glacier Overlook, well before the alpine section is cleared. Only the middle stretch over Logan Pass waits for plowing to finish.
What Tours Work If Logan Pass Is Closed?
West-side driving tours covering Apgar and Lake McDonald, guided nature walks, Middle Fork rafting trips, and the Lake McDonald boat tour all run below the closure points. Audio tours also work on whichever sections are open, since they are per-group purchases rather than fixed-departure products.
When Does Going-To-The-Sun Road Close For The Season?
Typically around the third Monday in October, weather permitting. The verified record shows season closings as early as September 3 in the 2017 fire year and as late as October 19 in 2009.
Do You Need A Vehicle Reservation To Drive The Road?
Not in 2026. The park required no vehicle reservations anywhere this season. What applied instead was a ticketed shuttle to Logan Pass and a three-hour parking limit at the pass lot, both from July 1 to September 7, 2026.
