The Going-to-the-Sun Road opens to Avalanche Creek each spring, and the campground follows shortly after - but only if you secured a reservation six months in advance. This 87-site campground sits 15.7 miles from the West Glacier entrance, placing you at the trailheads for both the Trail of the Cedars and Avalanche Lake, two of the most walked paths in the park. If you are planning a Glacier trip for summer 2026, this is the campground you need to understand before Recreation.gov opens the booking window.

How the Rolling Window Works
Campsites at Avalanche Campground become available on a rolling basis, 180 days out from your desired arrival date. That means if you want a site for July 15, 2026, you need to be on Recreation.gov six months to the day before that. The system releases sites at 8 AM Eastern time, and they go fast.
What the park website does not tell you: mid-July through August fills within minutes of release. September dates are slightly easier, but not by much. The campground operates on a reservation-only basis - there are no first-come sites here. Show up without a reservation and you will be directed elsewhere.
Fees and What They Cover
The summer fee runs $30.00 per night as of 2026. That covers up to eight people and two vehicles per site, space permitting. You can set up a maximum of two tents per site. The $30 fee applies per night, not per person, which makes this campground relatively affordable compared to nearby private options.
Site Specifics and Layout
Vehicle Length Limitations
Of the 87 total sites, only 50 can accommodate vehicles up to 26 feet. If you are driving anything longer than that - a full-size RV, a truck with a large trailer - you need to look elsewhere in the park. Those 50 sites are not marked on the reservation map as clearly as they should be. Cross-reference the site descriptions on Recreation.gov with your vehicle length before you book.
The remaining 37 sites work fine for tents, vans, and smaller rigs. The campground is located in a heavy timber area, so expect shade and some rooty ground at tent pads.
Loop Arrangement
The campground is organized in loops off a single access road. Sites close to the restroom facilities tend to book first. The upper loop sites have slightly more privacy from road noise. None of the sites are what you would call spacious - this is a national park campground, not an RV resort. Expect close neighbors.
The Going-to-the-Sun Road Factor
Current Access Status
As of spring 2026, the Going-to-the-Sun Road is open to Avalanche Creek on the west side of the park. On the east side, the road is open to Rising Sun. This matters because the park closure alert is active: travel on open sections may change due to spring weather conditions. Check road conditions before your arrival.
This means Avalanche Campground functions as the practical endpoint of the west side road during shoulder season. Day hikers headed to Logan Pass cannot make it through yet. The campground itself opens for the summer season around mid-July and runs through mid-September. The winter closure runs from approximately September 22 through July 6.
Hiking and Wildlife
Trail of the Cedars
This is the accessible boardwalk trail that starts directly from the campground. It is a 0.7-mile loop through old-growth western red cedar and hemlock forest. The trail narrows here in places where the boardwalk passes between massive tree trunks. Early morning is your best bet for seeing deer and occasionally moose along the creek corridor.
Keep an eye out for the interpretive signs along the boardwalk - they identify the primary tree species and explain the fire history of this drainage. The trail is flat and suitable for most fitness levels.
Avalanche Lake Trail
This is the reason most people book this campground. The trail starts at the same trailhead as the Trail of the Cedars and climbs 2 miles (one way) to Avalanche Lake. The elevation gain is worth it - roughly 730 feet spread over the distance, nothing extreme. From this overlook you can see the lake stretching back toward the surrounding peaks, with waterfalls cascading off the headwall.
Pack extra water for this stretch. The trail gains elevation steadily through the first mile and the afternoon sun can be intense even in the timber. Most visitors underestimate how much water they need for the round trip. Rangers will tell you to carry at least a liter per person for the 4-mile round trip.
Cell service drops out at the trailhead and does not return until you are back near the campground entrance. Download your maps before you arrive.
Wildlife Viewing
Avalanche Creek drainage supports black bears, deer, mountain goats on the higher slopes, and a wide range of bird species. Bring binoculars. The campground sits in a riparian corridor that funnels wildlife movement. Early morning and evening hours produce the most sightings. Store all food and scented items in the bear-proof lockers at each site - rangers check compliance regularly.
Practical Operations
Contact and Booking Information
All reservations go through Recreation.gov. The phone number for reservations is 1-877-444-6777. The park's general email is glac_questions@nps.gov, but there is no direct email for the campground specifically. For general park information, the official website is nps.gov/glac.
What to Expect On-Site
Standard national park campground amenities: vault toilets, potable water, bear-proof food storage lockers. No showers, no electrical hookups, no dump station. The general store at Lake McDonald Lodge, about 8 miles west on the Going-to-the-Sun Road, has basic supplies and ice.
The parking situation here is tight. If you are driving two vehicles to one site, make sure the site can physically accommodate both before you arrive. Overflow parking is limited.
Practical Takeaways
- Book exactly six months out. Mark your calendar for 8 AM Eastern on the reservation release date. September dates are easier than July or August.
- Confirm your vehicle fits. Only 50 of 87 sites handle vehicles up to 26 feet. Read the site-specific notes on Recreation.gov.
- Arrive with supplies. No showers, no hookups, no dump station. Fill your water tanks and stock groceries in West Glacier before you drive in.
- Download offline maps. Cell service drops at the trailhead. Have trail directions saved to your phone before you lose signal.
- Store everything edible in bear lockers. This rule gets enforced. Rangers will cite violators.
- Check road status before you go. The Going-to-the-Sun Road spring conditions change quickly. Call or check the park alerts page the morning of your departure.
Final Thoughts
Avalanche Campground earns its popularity for a straightforward reason: it sits at the base of one of Glacier's best day hikes, in a stretch of old-growth forest that feels different from the alpine terrain most visitors come to see. The trade-off is the reservation hassle and the relatively short season. If you can get a site here in August, you save yourself the daily drive from Fish Creek or Apgar, and you gain the ability to hit the Avalanche Lake trail before the crowds build. That alone justifies the planning required. For more on navigating Glacier's camping options, check the complete visitor guide for additional tips and strategies.
