RV Camping at Glacier National Park: The Complete Guide for 2026

Glacier National Park is the crown jewel of Montana camping — and one of the most frustrating places to bring an RV. The scenery is world-class: glacier-carved peaks, turquoise lakes, and wildlife you’ll actually see. But the campgrounds were built in an era when a 16-foot trailer was a big rig. If you’re rolling up in anything over 25 feet, you need a plan. If you want hookups, you need to look outside the park.

This guide covers every campground option for RVers — the four reservation campgrounds inside Glacier, the best private parks clustered around the entrances, and the practical details that determine whether your trip is a highlight or a headache. Every price, site count, and amenity listed here was verified directly on recreation.gov and Campendium in April 2026.

The Rig Size Problem — Read This First#

Before we get into specific campgrounds, let’s address the elephant in the room: Glacier National Park has the strictest vehicle size limits of any major national park.

Going-to-the-Sun Road — the park’s iconic 50-mile scenic drive — prohibits vehicles and vehicle combinations longer than 21 feet or wider than 8 feet (including mirrors) between the Sun Point parking area and Avalanche Campground. That’s not a suggestion; it’s enforced.

Inside the park campgrounds themselves, most campsites and driveways are very small. The National Park Service explicitly states that most sites “will not accommodate towed units over 21 feet.” A limited number of sites can handle towed units between 26 and 30 feet, but these are the exception.

What this means for you:

• Class B van or truck camper under 21ft: You can go anywhere in the park, including over Going-to-the-Sun Road. You have the most options.
• Travel trailer or 5th wheel 21-30ft: You can camp at Apgar, Fish Creek, and St. Mary (select sites), but you cannot drive GTSR. Plan to unhitch and drive your tow vehicle over the road separately.
• Class A, Class C, or any rig over 30ft: You’re limited to private parks outside the park boundaries. No in-park campground will realistically accommodate you.
• Slide-outs: Many Glacier Campground explicitly warns that most sites cannot accommodate slide-outs. St. Mary is recommended if you need them.

Don’t trust your GPS for routing inside the park. Multiple recreation.gov listings warn against it. Use the NPS driving directions instead — especially approaching Fish Creek from the west.

Inside the Park: Reservation Campgrounds#

All four of Glacier’s reservation campgrounds are on recreation.gov with a 6-month rolling booking window plus 4-day short-term releases. None have hookups — this is dry camping with shared water spigots and vault or flush toilets. Plan your battery and water capacity accordingly.

Apgar Campground — The Best All-Around Option for RVers#

Apgar is the largest campground in Glacier National Park with 194 sites, and it’s the most practical choice for RVers. It sits near the West Glacier entrance at roughly 3,200 feet — low enough that the season runs from May 1 through September 29, the longest of any Glacier campground. That alone makes it valuable: you get an extra month on each end of the season compared to the east-side campgrounds.

The campground is heavily forested with mixed conifers, providing genuine shade and privacy between sites. Some sites on the outer edges offer views of Lake McDonald — these book fastest, so grab them the moment the 6-month window opens. Lake McDonald sunsets are a short stroll from camp, and nightly ranger programs run at the on-site amphitheater throughout the season.

What sets Apgar apart from Fish Creek for RVers: Apgar has showers. Fish Creek does not. Both have dump stations and flush toilets, but if you’re dry camping for multiple days, the shower situation matters. Apgar also has accessible campsites and campfire circles at every site.

The downsides: cell coverage is rated “Major Cell Coverage Issues” across 814 recreation.gov reviews. If you need to work remotely or stay connected, you’ll struggle here. The proximity to the West Glacier entrance means slightly more traffic noise than the deeper-in-the-park campgrounds.

• Hookups: None (nonelectric)
• Sites: 194 (largest in Glacier NP)
• Cost: $30/night standard, $8/person walk-to
• Season: May 1 – September 29, 2026 (longest in the park)
• Reservation: Recreation.gov, 6-month rolling window
• Cell signal: Major coverage issues (recreation.gov, 814 reviews)
• Amenities: Flush toilets, potable water, dump station, showers, amphitheater, campfire circles
• Max RV: Select sites accommodate 26-30ft towed; most limited to 21ft
• Best for: RVers who want the most practical in-park experience with showers and the longest season

Fish Creek Campground — The Forested Retreat#

Fish Creek is the second-largest campground at 178 sites spread across three loops. It sits four miles northwest of the West Glacier entrance at about 3,500 feet elevation, tucked deeper into the park than Apgar. The forest here is denser — old-growth conifers provide heavy shade that keeps sites noticeably cooler on hot summer days.

The three-loop layout offers distinct character. Loop C is the no-generator loop — if you value silence and can handle the battery drain, this is where you want to be. Loops A and B allow generators during restricted hours. Some Loop A sites have partial views of Lake McDonald, though they’re more filtered through trees than Apgar’s lake-adjacent sites.

Fish Creek’s season runs May 22 through September 3 — about two months shorter than Apgar. The campground sits in what NPS calls the area “that generally receives the most rainfall” in the park, so come prepared for afternoon showers even in July and August. Nighttime temperatures routinely drop into the 40s even in midsummer at this elevation.

The honest downside: no showers at Fish Creek. You get flush toilets and a dump station, but for showers you’ll need to drive to Apgar or the Swiftcurrent Motor Inn area. For multi-day stays, this matters. Cell coverage is rated “Major Cell Coverage Issues” across 1,064 reviews — similar to Apgar.

Rocky Point Trail starts within walking distance of the campground, winding through a 2003 burn area that’s now regenerating forest — an interesting ecological walk. Nightly ranger programs run at the on-site amphitheater.

• Hookups: None (nonelectric)
• Sites: 178 across 3 loops (Loop C = no generators)
• Cost: $30/night standard, $8/person walk-to
• Season: May 22 – September 3, 2026
• Reservation: Recreation.gov, 6-month rolling window
• Cell signal: Major coverage issues (recreation.gov, 1,064 reviews)
• Amenities: Flush toilets, potable water, dump station, amphitheater, ranger station — no showers
• Max RV: Select sites for 26-30ft towed; most limited to 21ft
• Best for: Tenters and small RVers who prioritize forest immersion and quiet (Loop C)

St. Mary Campground — Best for Big(ger) Rigs and Cell Signal#

St. Mary is the sleeper pick for RVers, and here’s why: it’s the only Glacier campground with good cell coverage (confirmed “Good Coverage” across 653 recreation.gov reviews), it has the earliest opening date (April 18 — a full two weeks before Apgar), and it’s on the east side where Going-to-the-Sun Road restrictions don’t apply to reach it.

The campground sits near the east entrance at roughly 4,500 feet, with three loops. Loop A prohibits generators; Loops B and C allow them. The landscape is distinctly different from the west side — sparse aspen groves instead of dense conifers, which means less shade but dramatic mountain views of Singleshot, East Flattop, and Red Eagle peaks as a backdrop.

Because you don’t have to navigate GTSR to reach St. Mary, larger rigs that would be impossible on the west side can access this campground directly from Highway 89. It’s still nonelectric dry camping, but the sites are generally more accommodating for bigger setups than Many Glacier.

The best value play in Glacier: shoulder season at St. Mary runs $20/night (April 18 – May 21) before peak pricing kicks in at $30. You get the campground nearly to yourself, wildlife is more active in spring, and the east-side mountains are stunning with late-season snow. Late season is also interesting: August 17 through September 11, the campground switches to day-of reservations only — meaning no advance booking required. Just show up.

St. Mary Visitor Center is half a mile away with shuttle service and Red Bus tour departures. Restaurants, groceries, and gas are a couple of miles outside the park entrance.

• Hookups: None (nonelectric)
• Sites: Largest on east side, 3 loops (A = no generators, B & C = generators)
• Cost: $20/night shoulder season (Apr 18 – May 21), $30/night peak (May 22 – Sep 11)
• Season: April 18 – September 11, 2026 (earliest opening in Glacier)
• Reservation: Recreation.gov, 6-month rolling. Aug 17–Sep 11 = day-of reservations only.
• Cell signal: Good coverage (recreation.gov, 653 reviews) — best in the park
• Amenities: Flush toilets, potable water, dump station, amphitheater, fire pits
• Max RV: More accommodating than west-side campgrounds; east entrance avoids GTSR restrictions
• Best for: RVers who need cell signal, remote workers, bigger rigs, shoulder-season budget campers

Many Glacier Campground — For Hikers, Not RVers#

Many Glacier has the best hiking access in the park — Grinnell Glacier, Iceberg Lake, and Ptarmigan Tunnel trailheads are all close by. But for RVers, it’s the most restrictive campground in Glacier. The NPS explicitly recommends St. Mary for anyone with slide-outs, most sites won’t accommodate towed units over 21 feet, and there’s zero cell service — not weak signal, literally nothing.

The campground sits at 4,500 feet on the east side, 22 miles from St. Mary along a winding mountain road through Babb. The setting is spectacular — mature Douglas fir, lodgepole pine, and quaking aspen forest. But the season is brutally short: June 12 through September 12.

No dump station. No showers on-site (coin-op available at nearby Swiftcurrent Motor Inn, which also has a restaurant, camp store, and limited groceries). Flush toilets with cold water only. Camper utility sinks for gray water disposal.

If you’re a dedicated hiker with a small rig (Class B, truck camper, or pop-up under 21 feet) and you can live without connectivity for a few days, Many Glacier is magical. For everyone else, it’s a day-trip destination from St. Mary or the private parks outside the west entrance.

• Hookups: None (nonelectric)
• Sites: ~109 sites, single loop with generator-free zones
• Cost: $30/night standard, $8/person tent-only, $90/night group
• Season: June 12 – September 12, 2026 (shortest season)
• Reservation: Recreation.gov, 6-month rolling window
• Cell signal: No service (recreation.gov, 394 reviews). Limited signal in Babb, 12 miles east.
• Amenities: Flush toilets (cold water), potable water spigots, gray water sinks — no dump station, no showers
• Max RV: 21ft towed limit enforced. Slide-outs not accommodated on most sites.
• Best for: Hikers with small rigs who can disconnect for a few days

Outside the Park: Private RV Parks#

If your rig is over 25 feet, needs hookups, or you simply want a hot shower every night, the private parks clustered around Glacier’s entrances are your play. They’re more expensive, but they solve the rig size and hookup problem entirely.

West Glacier KOA Resort — The Full-Service Basecamp#

The West Glacier KOA is three miles from the West Entrance and it’s the most reviewed private park in the Glacier corridor for good reason. With 165 sites, full 30/50-amp hookups, gravel pads, and a max length of 75 feet, this is where the big rigs go. The longest RV reported by Campendium users is a 40-foot fifth wheel.

Campendium reviewers call it the “Taj Mahal of RV Parks” — it has a heated pool, adult hot tubs, the Bear Garden bar, a camp store, laundry, and a dog park. The grounds are well-maintained and mostly quiet (for a KOA). Sites are level gravel with enough spacing that you’re not staring into your neighbor’s bedroom window.

The honest price tag: $133–167/night depending on site and season, per recent Campendium reports. That’s steep — you’re paying a premium for the Glacier proximity and resort amenities. But if you’re comparing it to the $30/night in-park campgrounds, remember: those have no hookups, no showers (except Apgar), and a 21-foot rig limit. The KOA is solving a different problem.

Cell signal is solid: AT&T 4G/5G confirmed by 13 Campendium users (last reported June 2025), Verizon 4G by 13 users, T-Mobile 4G by 3 users. You can work remotely from here.

• Hookups: Full (30/50 amp, water, sewer)
• Sites: 165, pull-throughs and back-ins, gravel pads
• Cost: $133–167/night (Campendium, 2024-2025 reports)
• Max RV: 75 ft official, 40 ft reported (5th wheel)
• Cell signal: AT&T 4G/5G (13 users), Verizon 4G (13 users), T-Mobile 4G (3 users)
• Amenities: Pool, hot tubs, bar, camp store, laundry, dog park, big rig access
• Campendium reviews: 36 reviews, highly rated
• Location: 355 Halfmoon Flats Rd, West Glacier — 3 miles from West Entrance
• Best for: Big rigs, families wanting resort amenities, remote workers needing reliable connectivity

Other Private Options Near Glacier#

Glacier Peaks RV Park — 60 spacious sites near Columbia Falls. A quieter, less resort-style alternative to the KOA if you want full hookups without the pool-and-bar scene.

Glacier Meadow RV Park — Positioned between East and West Glacier, which is strategically smart if you plan to explore both sides of the park without relocating your rig.

West Glacier RV Park — In the West Glacier Village itself, steps from the park entrance along the Middle Fork of the Flathead River. Free WiFi, laundry, and a dog park. The most “walkable” option — you can access the village on foot.

Planning Your Glacier RV Trip#

Reservation Strategy#

Glacier campgrounds on recreation.gov use a 6-month rolling window — meaning exactly 6 months before your arrival date, sites become available. For peak summer (July–August), you need to be online at the exact release time. Set a calendar reminder for the morning 6 months out.

The 4-day short-term release is your backup: a handful of sites are released 4 days before the stay date. These go fast but they’re your shot if you missed the 6-month window.

St. Mary’s late-season play: August 17 through September 11, St. Mary switches to day-of reservations. No advance booking. Show up, reserve online that morning, and camp. Fall color in the aspens makes this a legitimate strategy, not a consolation prize.

Bear Safety for RVers#

This is grizzly and black bear country — not theoretically, but literally. Bears frequent every campground in Glacier. Food storage regulations are strictly enforced.

When not in immediate use, all food, beverages, coolers, cooking utensils, pet food, and any other attractant must be stored in a closed, hard-sided vehicle or in the bear-proof storage lockers near campground restrooms. Your RV counts as a hard-sided vehicle, but you need to actually close it up — open awnings with food on the table are a citation.

Bear spray is recommended and available for purchase (or rent) in West Glacier and St. Mary. Keep it accessible, not buried in a storage compartment.

Shoulder Season Advantages#

Glacier’s shoulder seasons are underrated:

Late April–May (St. Mary only): $20/night, minimal crowds, snow-capped peaks, active wildlife. Going-to-the-Sun Road won’t be fully open yet (it typically opens in late June), but the east-side hiking is accessible.

September: Fall color in the aspens, thinner crowds, still-warm days, cooler nights. Apgar stays open through September 29. St. Mary transitions to walk-up day-of reservations after August 17 — potentially the easiest booking of the season.

Fuel, Groceries & Services#

West side: Gas and basic groceries in West Glacier. Kalispell (33 miles) has full services — Costco, Walmart, hardware stores. Stock up there before entering the park.

East side: Gas, groceries, and restaurants in St. Mary (outside the park). Babb has a general store, gas station, and a few restaurants. For anything substantial, Browning or Cut Bank are your options.

Dump stations: Apgar, Fish Creek, and St. Mary campgrounds all have dump stations. Many Glacier does not. For private parks, West Glacier KOA has full hookups with at-site sewer.

Propane: Available in West Glacier, Columbia Falls, and Kalispell. Not available inside the park.

The Bottom Line#

If you’re bringing an RV to Glacier, your strategy depends entirely on your rig size:

Under 21 feet: You have the full park at your fingertips. Apgar for the longest season and showers. St. Mary for cell signal and the $20 shoulder rate. Many Glacier for the hiking.

21-30 feet: Apgar and St. Mary are your realistic options inside the park. Book 6 months out. Accept that GTSR requires unhitching.

Over 30 feet: West Glacier KOA or the other private parks. There’s no shame in it — you’ll have full hookups, hot showers, and a cold beer at the Bear Garden while the dry-camping crowd is rationing their water tank. Day-trip into the park by car.
