Is Grand Teton National Park Open? 2026 Park Hours, Closures & Updates
Yes — Grand Teton National Park is open in 2026. The park itself is open 24 hours a day, 365 days a year, including weekends and holidays. However, being open does not mean every road, visitor center, campground, trailhead, or service is operating year-round. Seasonal closures and ongoing construction are particularly important to check before a 2026 visit.
As of September 26, 2026, Grand Teton remains open, but several areas have active construction-related closures and delays. The National Park Service recommends checking current conditions immediately before traveling because road and trail conditions can change.
Grand Teton National Park Hours in 2026
Unlike a museum or attraction with a daily opening and closing time, Grand Teton National Park does not have a general daily closing time.
| Park information | 2026 status |
|---|---|
| Park access | Open 24 hours |
| Open season | Year-round |
| Popular visitor season | May–September |
| Winter access | Available, but many facilities and some roads close |
| Visitor centers | Seasonal |
| Campgrounds | Mostly seasonal |
| Roads | Some year-round, others seasonal |
| Construction | Active in several areas during 2026 |
The NPS says the park is open 24 hours every day throughout the year. From November through April, however, some roads, all campgrounds and most visitor facilities are closed or operate on reduced schedules.
Is Grand Teton Open Right Now?
Yes. Grand Teton National Park is open right now.
For visitors traveling in late September 2026, many of the park’s major areas remain accessible, but several seasonal facilities are beginning to close and some roads and trails are affected by construction.
The NPS’s September 2026 conditions page lists these important disruptions:
- Moose-Wilson Road between Moose and the Laurance S. Rockefeller Preserve — closed
- Death Canyon Road and Trailhead — closed
- Menors Ferry Road — closed to all use on weekdays
- Teton Park Road roundabout near Moose Entrance Station — approximately 20-minute construction delay
- North Park Road — open, with intermittent daytime delays
- Taggart Lake Trailhead — open, but construction is ongoing
- Cottonwood Creek Picnic Area — closed
- Mormon Row Historic District — open, although access to some buildings is restricted
These are area-specific closures, not a closure of the entire national park.
What Is Closed at Grand Teton National Park in September 2026?
If you’re visiting Grand Teton in late September, the most important thing is to distinguish between the park being open and individual locations being closed.
1. Moose-Wilson Road
One of the biggest 2026 changes involves the Moose-Wilson Road.
The section between Moose and the Laurance S. Rockefeller Preserve is scheduled to remain closed to motor vehicles and bicycles from September 7 through November 15, 2026, because of ongoing construction. After November 15, the corridor is expected to transition toward winter recreational use as conditions allow.
If this road is part of your itinerary, check the latest conditions and plan an alternate route.
2. Death Canyon Road and Trailhead
Death Canyon Road and the Death Canyon Trailhead are closed for construction during the 2026 season.
This is particularly important for hikers because you cannot simply drive to the normal Death Canyon Trailhead and begin the hike as you might in an unaffected year.
3. Taggart Lake Trail
The Taggart Lake Trailhead and parking area remain open, but construction is affecting the trail.
The northern portion of the Taggart Lake Trail is closed for reconstruction. The southern route to Taggart Lake remains available, although it is longer and steeper, at approximately 4.25 miles round trip according to the NPS.
4. Cottonwood Creek Picnic Area
The Cottonwood Creek Picnic Area is closed because of construction. Visitors should follow posted signs and stay outside active construction zones.
Are Grand Teton Roads Open?
Some are, and some are not.
This is one of the most important things to understand when planning a Grand Teton trip.
The main U.S. Highway 26/89/191, also known as the Outer Park Road, is open. The NPS describes it as a major scenic route through the park.
However, individual park roads have their own seasonal schedules.
Teton Park Road
Under normal seasonal operation, the Teton Park Road between Taggart Lake Trailhead and Signal Mountain Lodge closes to motor vehicles from November 1 through April 30. During winter, sections are used for activities such as skiing and snowshoeing.
Moose-Wilson Road
The Moose-Wilson Road normally closes seasonally around November and reopens in spring depending on conditions. In 2026, construction has created an additional extended closure affecting the Moose–Laurance S. Rockefeller Preserve section.
Other secondary roads
Roads including Antelope Flats, Schwabacher, Two Ocean and other secondary routes can also close seasonally depending on weather and conditions.
Grand Teton Visitor Centers: 2026 Hours & Closures
The park may remain open while individual visitor centers close for the season.
For example, the Craig Thomas Discovery and Visitor Center in Moose is scheduled to operate daily from April 10 through October 31, 2026.
The Jenny Lake Ranger Station is closed for its winter season beginning September 8, 2026, and is scheduled to reopen June 6, 2027.
The Laurance S. Rockefeller Preserve Center entered its winter closure beginning September 21, 2026.
Some other visitor services remain available later into fall, while others have already ended their 2026 season.
Why this matters
If you need:
- Backcountry information
- Permits
- Ranger assistance
- Maps
- Visitor information
- Park stores
- Exhibits
check the operating schedule of the specific visitor center rather than assuming every facility is open because the park itself is open.
Are Grand Teton Campgrounds Open in 2026?
Campgrounds at Grand Teton are generally seasonal rather than year-round.
For example, the NPS lists these 2026 operating dates:
- Gros Ventre Campground: April 27–October 10
- Jenny Lake Campground: May 2–September 27
- Signal Mountain Campground: May 8–October 11
- Colter Bay Campground: May 21–September 27
- Lizard Creek Campground: June 12–September 13
- Headwaters Campground and RV Park: June 7–October 4
Because campground dates can change, check the official NPS operating schedule before relying on a specific campground for an overnight stay.
Is Grand Teton Open in Winter?
Yes. Grand Teton remains open during winter.
The difference is that winter visitors should expect significantly fewer services and more seasonal road closures.
The NPS states that the park remains open year-round, while many facilities and some roads close during winter.
The Outer Park Road (US 26/89/191) is open year-round within the park, while other roads have seasonal closures.
Winter can therefore be a very different experience from a summer road trip. Snow, ice, limited services and changing road conditions need to be considered.
Is Grand Teton Open in October 2026?
Yes, but October is a transition period.
Grand Teton itself remains open 24/7, but many summer businesses, campgrounds and visitor facilities close during September and October.
For example:
- Jackson Lake Lodge is scheduled through October 4.
- Signal Mountain Lodge is scheduled through October 11.
- Gros Ventre Campground is scheduled through October 10.
- Colter Bay RV Park is scheduled through October 10.
- Craig Thomas Discovery and Visitor Center remains scheduled through October 31.
This means October visitors should plan around the specific facilities they intend to use.
Is Grand Teton Open in November 2026?
Yes, the national park itself remains open.
However, November marks the beginning of substantial seasonal changes.
The Teton Park Road normally closes to motor vehicles from November 1 through April 30, while the Moose-Wilson Road has its own seasonal closure schedule.
Most campgrounds and many visitor facilities will also be closed by November.
If you’re visiting during November, check the official road status immediately before driving into the park.
Grand Teton 2026 Construction: What Visitors Should Know
Construction is one of the biggest factors affecting access during the 2026 season.
The NPS says several major infrastructure projects are underway and that impacts can include road closures, trail closures, traffic delays and changes to access. Project schedules can change.
Current September 2026 disruptions include:
| Location | Current situation |
|---|---|
| Moose-Wilson Road | Closed between Moose and LSR Preserve |
| Death Canyon Road | Closed |
| Death Canyon Trailhead | Closed |
| Menors Ferry Road | Closed weekdays |
| Taggart Lake Trailhead | Open with construction |
| Taggart Lake Trail | Partially open |
| Cottonwood Creek Picnic Area | Closed |
| Mormon Row | Open with some restricted building access |
| North Park Road | Open with intermittent delays |
| Moose roundabout | Construction delays |
Always check the NPS current conditions page shortly before your trip because these conditions are subject to change.
Does Grand Teton National Park Charge an Entrance Fee?
Yes.
For 2026, the standard private vehicle entrance fee is $35 for seven days. The motorcycle fee is $30, while visitors entering without a vehicle who are 16 or older pay $20 per person.
There is also an important 2026 payment change: Grand Teton became cashless on May 1, 2026 for park entrance fees and several permits. Electronic payment methods such as credit/debit cards, contactless payment and mobile wallets are accepted.
International visitors should also check the NPS’s current nonresident fee information before traveling because additional fees may apply.
How to Check If Grand Teton Is Open Before Your Trip
Because road and trail conditions can change quickly, don’t rely only on an old travel blog or social media post.
Before leaving for Grand Teton, check these three official NPS resources:
- Current Conditions & Alerts — for temporary closures and construction.
- Park Roads — for road status and seasonal closures.
- Operating Hours & Seasons — for visitor centers, campgrounds, lodges and other facilities.
The NPS specifically warns that road conditions can change quickly and that short-term closures or delays may not always immediately appear on the road-status map.

Tips for Visiting Grand Teton During a Closure or Construction
A closure doesn’t necessarily mean you need to cancel your trip. Instead, adjust your route.
1. Check road conditions before leaving
Construction schedules can change, and the NPS recommends checking current conditions before traveling.
2. Keep alternate routes available
If Moose-Wilson Road is part of your itinerary, plan an alternative using the main highway network.
3. Don’t enter closed areas
Road and trail closures are established for visitor safety, construction work or resource protection. Follow barricades and posted signs.
4. Allow extra driving time
Construction can create delays, especially around the Moose area.
5. Check facility dates separately
A campground, restaurant or visitor center may be closed even though the national park itself is open.
6. Visit a visitor center when one is operating
Rangers can provide updated information about hiking routes, road conditions and current restrictions.
