The full length of Going-to-the-Sun Road is expected to open to motorized vehicles Monday, June 16, for the 2025 summer season.
As a reminder, timed entry vehicle reservations are required to enter Going-to-the-Sun Road from the west side of the park for those traveling by vehicle or motorcycle from 7 a.m. to 3 p.m. beginning June 13 through September 28. Complete information on timed entry vehicle reservations can be found online at https://www.nps.gov/glac/planyourvisit/vehicle-reservations.htm.

Ahead of the full opening, beginning June 14, the east side of the Going-to-the-Sun Road will be open to vehicles and motorcycles from the St. Mary Entrance to Logan Pass. Some popular trails, such as the Highline Trail, remain closed due to hazardous snowy conditions. For up-to-date information on trail conditions and clearing activities, visit the park’s trail status webpage.
This will be the last weekend for bicyclists to bike the west side of Going-to-the-Sun Road before it is projected to open to motorized vehicles on Monday, June 16. As a reminder for bicyclists coming from the West Entrance heading eastbound (uphill) on Going-to-the-Sun Road, there is still an active closure, past the loop, due to a wildlife incident. Visitors are reminded of proper bear safety, such as if you see a bear along the road, do not stop near it. Roadside bears quickly become accustomed to traffic and human presence. Carry bear spray, know how to properly use it, and make sure it is accessible. This will be the last weekend of the hiker/biker shuttle for the season. More biking information can be found at Bicycling – Glacier National Park (U.S. National Park Service).
As we prepare for the road opening, bicyclists should be mindful of administrative vehicle traffic, especially on Thursday, June 12, and Friday, June 13, while bus operators are in training. Bicyclists are reminded to wear a helmet, bring extra clothes as conditions can change quickly, never leave food unattended, and bring the necessary tools to change a tire. Bicyclists are required to have a timed entry vehicle reservation if they want the opportunity to park at Avalanche to bike from 7 a.m. to 3 p.m., during their selected time slot. Going-to-the-Sun Road may become busier after 3 p.m. when timed entry vehicle reservations are no longer required for the day.
For safety concerns, bicycle restrictions are in place when the road is open to motor vehicles as described below:
Eastbound:
- From June 13 through June 15, bicycles are prohibited from going eastbound (uphill) between 12 p.m. and 6 p.m. from Apgar to Avalanche.
- Beginning June 16, when Going-to-the-Sun Road fully opens, through September 28, bicycles are prohibited from going eastbound (uphill) between 12 p.m. and 6 p.m. from Apgar to Logan Pass.
Westbound:
- From June 13 through June 15, bicycles are prohibited from going westbound (downhill) between 3 p.m. and 6 p.m. from Avalanche to Apgar.
- Beginning June 16, when Going-to-the-Sun Road fully opens, through September 28, bicycles are prohibited from going westbound (downhill) between 3 p.m. and 6 p.m. from Logan Pass to Apgar.
Visitors are reminded that although the entirety of Going-to-the-Sun Road is projected to open on Monday, rockfalls or other natural events might delay this opening, as conditions can change quickly.
Going-to-the-Sun Road Reservations and Amenities
Visitor information services and the Glacier National Park Conservancy bookstore will be available at the Logan Pass Visitor Center starting June 14. Visitors are reminded to pack water and snacks as food and water are not available for purchase at the Logan Pass Visitor Center. Restrooms will be open.
When Going-to-the-Sun Road fully opens, the number of timed entry vehicle reservations available will be increased. The increase will be implemented through next-day reservations, available at 7 p.m. each day. Timed entry vehicle reservations are only available on Recreation.gov and not available at the park.
Timed entry vehicle reservations are required to enter Going-to-the-Sun Road from the west side of the park past Apgar Campground. Reservations will be required for those traveling by vehicle or motorcycle from 7 a.m. to 3 p.m. beginning June 13 through September 28, 2025. Visitors who miss their time block or visitors without a timed entry vehicle reservation can enter after 3 p.m.
Visitors with lodging, camping, or commercial activity reservations (e.g., boat tours and horseback rides) within the specified reservation areas can use proof of their reservation for entry instead of a timed entry vehicle reservation to gain access to the area for which they have a service reservation. Service reservations originating east of Logan Pass cannot be used instead of a timed entry vehicle reservation for access past the Apgar Check Point heading east on Going-to-the-Sun Road.
Parking at Logan Pass, Apgar Village, and other areas may be congested or temporarily unavailable. Daily shuttle service along Going-to-the-Sun Road will begin operating July 1, on a first-come, first-served basis at the Apgar and St. Mary Visitor Centers with stops along Going-to-the-Sun Road. Visitors are encouraged to take advantage of the free shuttle for hiker access to Logan Pass; however, wait times for shuttles may be long, depending on the time and location. Check the park website for additional information on shuttle stops.
While driving along the road, particularly through the Rim Rock area (approximately one mile west of Logan Pass), visitors should be aware of potential rockfall and should not slow down or stop in this section. Rocks and other debris continue to fall throughout the summer, requiring daily cleanup. With the level of snow at Logan Pass, visitors should use extreme caution and refrain from crossing snowfields or standing under snow overhangs.
North Fork
Timed entry vehicle reservations are also required for the North Fork beginning June 13 through September 28, from 7 a.m. to 3 p.m.
Many Glacier
As a reminder, the Many Glacier Valley has significantly reduced parking spots due to the construction project at Swiftcurrent. The road closure begins at the T-intersection just past the Many Glacier Hotel road. Although the Many Glacier Valley does not require a timed entry vehicle reservation in 2025, the area is already seeing high congestion and temporary closures. A Many Glacier Day Hiker Shuttle will take effect July 1. Learn more about the Many Glacier Construction on the Many Glacier Construction FAQs page.
Two Medicine
The Two Medicine area will not require timed entry vehicle reservations in 2025. Visitors may experience temporary restrictions due to congestion.
