Key Takeaways
- Going-to-the-Sun Road bans vehicles (including towed vehicles) over 21 feet between the Avalanche Creek and the Sun Point parking areas from late May through mid-October โ this rules out almost every Class A, fifth wheel, and travel trailer
- Columbia Falls and West Glacier have the most full-hookup parks within 10 miles of the west entrance; Whitefish (15 miles) trades proximity for better amenities and a real town nearby
- Inside-park campgrounds at Apgar, Fish Creek, and St. Mary take reservations through Recreation.gov โ July and August dates fill in January within hours of opening, not days
- September is the best month for most RV travelers: crowds drop, reservations open up, fall color starts, and the road restrictions loosen
- The east side of the park (St. Mary, Many Glacier, East Glacier) is less visited and more dramatic โ and harder to reach, which keeps the crowds manageable
Glacier National Park has a size problem โ not the park itself, which covers over a million acres, but the single road that crosses it. Going-to-the-Sun Road is one of the great scenic drives in North America and also one of the most restrictive for RVers. If your rig is over 21 feet (combined length, including any towed vehicle), you cannot drive the road during peak season. That changes how you plan your trip, but it doesn't make the park off-limits. It means you base camp outside the park and access the trailheads, shuttle system, and scenic pullouts from there.
Here's how to do it right โ where to park, what to book, and when to go.
The Road Restriction You Need to Know First
From roughly late May through mid-October, Going-to-the-Sun Road prohibits vehicles, RVs, and combinations (truck + trailer) longer than 21 feet between the Avalanche Creek parking area and Sun Point parking area โ the most scenic stretch. The 21-foot limit applies to the total length of any combination, including a towed dinghy. A 19-foot campervan with nothing in tow is fine. A 20-foot Class C with a towed vehicle is not. Check the NPS restrictions page before you book; the exact dates and measurement points vary slightly year to year.

Browse Idaho Parks โIf you have a larger rig, the strategy is to park at the Apgar Village lot or the St. Mary Visitor Center and catch the free Going-to-the-Sun shuttle. The shuttle runs July through early September and stops at most major trailheads. You see everything you'd see driving it, without the white-knuckle two-way traffic on 22-foot-wide ledge road.
West Side: Columbia Falls & West Glacier
The west entrance at West Glacier is the busiest entry point and closest to US-2, the main east-west highway. Columbia Falls โ about 8 miles from the entrance โ has the best concentration of full-hookup RV parks near the park. Sites fill by Memorial Day for July and August; if you're going in peak summer, book by February at the latest.
A few things to know about the west-side corridor:
- The Hungry Horse Reservoir area (south of Columbia Falls on US-2) has quieter, less expensive parks that are worth checking if the corridor fills up โ about 20 miles from the west entrance.
- Big rigs can handle US-2 without issue; the access roads into some west-side parks tighten up at 40+ feet, so call ahead if you're pulling a long fifth wheel.
- Cell service is inconsistent between Columbia Falls and the west entrance. Download offline maps and the Glacier shuttle schedules before you leave camp.
Browse Montana RV parks on RVSpot and filter by Columbia Falls or West Glacier to compare current pricing and amenities. Check recent reviews for notes on how well-maintained the grounds are in summer โ west-side parks get heavy use.

Whitefish: The Full-Service Base Camp
Whitefish is 15 miles from the west entrance and has the strongest amenity base in the region โ better grocery stores, restaurants, a walkable downtown, and RV parks with reliable 50-amp service and Wi-Fi. It costs you 20 extra minutes of driving to the park entrance each way, but if you're spending a week or more, having a proper town nearby is worth it.
Whitefish is also where you'll find most of the options if you're a remote worker making a summer base camp โ call ahead to confirm wi-fi speeds and hookup availability. The west-side parks closer to the entrance tend to be tighter on utilities, and the proximity premium means you pay more for less infrastructure.
If Glacier is the main event but you also want to fish, kayak Flathead Lake, or ride the mountain trails around Whitefish Mountain Resort, staging from Whitefish makes more sense than staging from the park entrance.
Inside the Park: NPS Campgrounds
Glacier has 13 campgrounds inside the park. Most are tent-only or designed for smaller vehicles, but a few accommodate RVs:
| Campground | Side | Hookups | Max RV Length | Notes |
|---|---|---|---|---|
| Fish Creek | West | Some 30-amp | 21 ft | Largest west-side campground; limited electrical sites book out first |
| Apgar | West | None | 21 ft | Walk to Lake McDonald; close to shuttle stops; very popular |
| St. Mary | East | Some 30-amp | 35 ft | Largest overall; good access for bigger rigs; east-entrance proximity |
| Many Glacier | Northeast | None | 35 ft | Remote, stunning; road to it is RV-manageable; bears are active here |
| Two Medicine | Southeast | None | 32 ft | Quietest, most overlooked area; excellent hiking with far fewer people |
All NPS campground reservations go through Recreation.gov. For July and August, you're competing with thousands of people at the moment the booking window opens โ typically in mid-January for summer dates. Set a calendar alarm. If you miss the booking window, a limited number of first-come, first-served sites open daily, but lines form early (often before 6 a.m.) in peak season.
The advantage of camping inside the park is access: you're minutes from trailheads, you don't need to drive Going-to-the-Sun in morning traffic, and the bear activity around camp (the park has over 300 grizzlies) is handled with bear boxes, so you follow the rules and it's genuinely fine. The disadvantage is no full hookups at most sites, size restrictions, and the booking competition.
East Side: St. Mary, East Glacier & Browning
Most visitors enter from the west. The east side of the park โ accessible via US-89 and US-2 from Great Falls or Havre โ is dramatically different and quieter. St. Mary is the main east-entrance town, with a few private RV parks that are steps from the park boundary. East Glacier Village, about 12 miles south of the east entrance on US-2, has basic services and a more relaxed pace than the crowded west side.
Many Glacier โ the northeast area accessed via Babb off US-89 โ is worth the extra drive. The road in is fine for most RVs up to 35 feet; check your rig against the current NPS guidance before committing. The views from the Many Glacier Hotel trailhead area are among the best in the park, and the campground there books out just as fast as Apgar but with a fraction of the day-use crowd.
Montana Beyond the Park: Flathead Lake & Missoula
If you're spending two or more weeks in western Montana, Glacier is the anchor but not the only stop. Flathead Lake โ about 30 miles south of Kalispell โ is one of the largest freshwater lakes west of the Mississippi, with RV parks on its eastern shore that have direct water access. Late July through August the lake is warm enough to swim.
Missoula, about 120 miles south of Kalispell on US-93, has a walkable university town with full-hookup RV parks, good restaurants, and access to the Clark Fork River trail system. It works well as a transition stop between Glacier and a southbound route through Idaho or the Wyoming Rockies covered in our Wyoming and Northern Rockies guide.
When to Go
July and August are peak season โ maximum wildflower blooms, all trails open, full shuttle service, and the most competition for everything. If your schedule is flexible:
- Late June: Going-to-the-Sun Road may still be clearing snow at higher elevations. Some high trails are snowbound. Fewer crowds, lower rates. Check NPS for current road conditions.
- September: The sweet spot for most RVers. Crowds drop by 30-40% after Labor Day, reservation systems open up, fall color starts showing on the east side by mid-month, and daytime temperatures are comfortable. The shuttle runs through early September.
- October: Going-to-the-Sun road restrictions lift in mid-October, meaning you can drive the full road regardless of rig length โ but campgrounds are mostly closed by then, and early snow is possible at elevation.
Whatever month you go, book your combination of outside-park RV park + any inside-park NPS sites well in advance. The outside-park parks in Columbia Falls and West Glacier fill up just as fast as the NPS sites during July-August.
Frequently Asked Questions
Can I drive Going-to-the-Sun Road in my RV?
Only if your rig is 21 feet or under (total length, including any tow vehicle) between Avalanche Creek and Sun Point, during the restricted season (roughly late May through mid-October). Compact Class B campervans fit. Full-size Class A, Class C with a dinghy, fifth wheels, and most travel trailers do not. Use the free NPS shuttle from Apgar or St. Mary instead โ it stops at all the main trailheads.
Where is the closest full-hookup RV park to Glacier National Park?
Columbia Falls has full-hookup parks roughly 8 miles from the west entrance โ as close as you'll get with 30/50-amp electric and water/sewer. West Glacier itself has a couple of smaller parks within 2 miles of the entrance, but amenities are limited compared to Columbia Falls.
Do I need a bear canister or bear box at Glacier campgrounds?
Yes. Glacier requires hard-sided storage for all food, scented items, and trash at NPS campgrounds. Most sites have bear boxes on-site; you can also use your locked vehicle. Never store food in a tent or unsecured outside your RV. The park's grizzly population is healthy and active โ the rules are real, and rangers enforce them.
Is it worth going to the east side of Glacier?
Yes, especially for RVers who want fewer crowds. The east side (St. Mary, Many Glacier, Two Medicine, East Glacier) is less visited than the west, the scenery is arguably more dramatic, and the big-sky prairie-meets-mountain landscape you hit driving in from the east is unlike anything on the west side. Many Glacier in particular is worth the extra miles.
How do I find RV parks near Glacier National Park?
Search by city on RVSpot โ Columbia Falls, West Glacier, Whitefish, St. Mary, and East Glacier are the key towns to compare. Filter for full hookups if you need 30/50-amp electric and water/sewer; a lot of west-side parks fill up fast, so read recent reviews to confirm sites are available and power is reliable during peak season. Browse the full Montana RV park directory to compare options.
