Mount Rainier RV Camping: Every Campground on the Mountain (2026)

Camping on Mount Rainier in an RV means Cougar Rock in 2026. It is the only one of the park’s three RV-capable campgrounds that is both open and reservable this year: 179 sites, $20 a night, a 35-foot RV or 27-foot trailer limit, no hookups, booked on Recreation.gov. Ohanapecosh is closed for the whole 2026 season for rehabilitation, White River is 27 feet and first-come only, and Mowich Lake is tents only. For hookups, showers or anything over 35 feet, the private RV parks in Ashford, Elbe and Packwood are the base.

Mount Rainier is a compact park with a giant mountain in the middle and only a handful of campgrounds around its base. That makes the RV math simple, but it also means the one good campground fills fast and the gateway parks matter more than at Yellowstone or Glacier. This guide covers each in-park campground, the outside-the-park options, and the length limits and closures that decide where you can actually park.

We verified sites, fees, length limits, seasons and 2026 status against the NPS Mount Rainier campgrounds page. Private-park details are described in general terms; check each operator for current rates and inventory. Washington’s other national park, Olympic, is a natural pairing; see our Olympic National Park RV camping guide.

Quick answer: Book Cougar Rock on Recreation.gov if your RV is 35 feet or under (27 feet if it is a trailer). Skip Ohanapecosh for 2026; it is closed. Try White River only with a rig under 27 feet and a flexible schedule, and check its fire-closure status first. Everything else — hookups, showers, big rigs — is in Ashford on the Nisqually side or Packwood on the southeast side.

Cougar Rock Campground: the RV campground at Mount Rainier#

Cougar Rock is on the Nisqually-to-Paradise road, a couple of miles above Longmire, at 3,180 feet. It is the park’s main campground for RVs and the one that shows up first in “campground Mount Rainier” searches for good reason: it is big, forested, close to Paradise, and it takes reservations.

• Location: Paradise Road between Longmire and Paradise, southwest corner of the park, entered from the Nisqually Entrance near Ashford.
• Hookups: None. Flush toilets and potable water; the dump station is closed until further notice.
• Sites: 179 individual, 5 group.
• Max rig length: 35-foot RV, 27-foot trailer.
• Cost: $20 per night individual, $60 group (NPS).
• Reservations: Recreation.gov.
• Generators: 8 to 10 a.m., noon to 2 p.m., 5 to 7 p.m.; prohibited in Loop E.
• Best feature: Paradise, the Skyline Trail and the Nisqually Glacier views are 20 minutes up the hill; Longmire’s museum and lodge are 10 minutes down.

The 35-foot RV limit is measured on the RV, with a separate 27-foot trailer limit, and the loops are old-growth forest with tight curves. A 35-foot Class A fits on paper; a 35-foot fifth wheel behind a truck does not, because the trailer figure is what governs. Sites are back-in gravel with fire rings and picnic tables. Loop E is generator-free and the quietest choice.

With no dump station in the park in 2026, arrive with tanks empty and plan your dump at a gateway park or a station in Ashford or Eatonville on the way out.

Ohanapecosh Campground: closed for 2026#

Ohanapecosh is normally the park’s other big RV campground, 179 sites in old-growth along the Ohanapecosh River near the Stevens Canyon Entrance, at a low 1,914 feet with a long late-May-to-late-October season and a 32-foot RV limit. For 2026 it is closed: the NPS says the rehabilitation project continues through November 2026, and no reservations are being taken.

That closure pushes the southeast side’s campers to Packwood, 7 or so miles south on US-12, where private RV parks with hookups pick up the slack, and to the La Wis Wis Forest Service campground nearby. If you are reading this for a 2027 trip, expect Ohanapecosh to return on Recreation.gov with updated facilities; check the NPS page before assuming the old 32-foot limit still applies.

White River Campground: small rigs, first-come, check the fire status#

White River sits at 4,400 feet on the road to Sunrise in the northeast corner, the highest drive-to point in the park. It is a walk-up campground for compact rigs.

• Location: White River Road off SR-410, on the way to Sunrise, entered from the White River Entrance near Enumclaw.
• Hookups: None. No dump station.
• Sites: 88 individual, no group sites.
• Max rig length: 27-foot RV, 18-foot trailer.
• Cost: $20, paid through the Recreation.gov mobile app by scanning the site QR code.
• Reservations: First-come, first-served only.
• Best feature: The Glacier Basin and Sunrise trailheads, and the shortest drive to Sunrise’s Emmons Glacier viewpoints.

At the time we checked, the NPS listed White River as closed until further notice because of the Grand Park 2 Fire. Verify its status before driving in; when it is open, the 27-foot RV and 18-foot trailer limits make it a van, truck-camper and small-trailer campground, and it fills by late morning on summer weekends.

Mowich Lake: no RVs#

Mowich Lake in the northwest corner is 13 primitive walk-in tent pads at 4,929 feet, no RVs or trailers, no potable water, and a wilderness permit is required. The gravel Mowich Lake Road was never RV territory anyway, and the NPS says the area is currently not accessible from SR-165 because of the Fairfax Bridge closure. Leave it off an RV itinerary.

Private RV parks outside the park: Ashford, Elbe and Packwood#

Because the park has no hookups, no showers and no working dump station in 2026, most RVers who spend more than two nights at Mount Rainier split time with a gateway park. Two corridors matter.

Ashford and Elbe (Nisqually Entrance, for Paradise and Cougar Rock)#

• Mounthaven Resort, Ashford: A small forested resort just outside the Nisqually Entrance with RV sites among cabins. The main appeal is being a few minutes from the gate for early Paradise starts. Site count, hookups and rates: see the operator’s current listing.
• Other Ashford and Elbe parks: The SR-706 corridor from Elbe to the entrance has several private RV parks and a state-run option on Alder Lake. Elbe is roughly 25 minutes from the gate; Ashford is 5 to 10. Confirm hookups and length limits with each operator, since some are tight forest sites and others open gravel pull-throughs.

Packwood (Stevens Canyon and Ohanapecosh side, also for Sunrise via SR-123/410)#

• Packwood RV Park and Campground: The town’s main RV park, on US-12, with hookup sites and a location that reaches both the Stevens Canyon Entrance and, via Cayuse Pass, the White River side. With Ohanapecosh closed in 2026 it is the practical base for the southeast side. Rates, site count and length limits: see the operator.
• La Wis Wis (Gifford Pinchot National Forest): A Forest Service campground between Packwood and the park boundary, dry, small-rig friendly, on Recreation.gov. Useful as a no-hookup alternative to a closed Ohanapecosh.

Our take: Ashford is the base for a first Rainier trip because Paradise is the park’s must-see and Cougar Rock is the only open in-park campground. Packwood is the base for a second trip, for Sunrise-plus-Ohanapecosh itineraries once that campground reopens, and for anyone continuing east over White Pass.

Practical notes for RVers#

Big rigs at Mount Rainier#

There is no in-park option over 35 feet, and no in-park trailer over 27. If you are in a 40-foot fifth wheel or Class A, base outside the park and drive the toad or truck in. The park roads themselves are fine for those rigs to Paradise and Sunrise as vehicles, but you cannot camp them inside. Our national park RV rig size limits guide shows how Rainier’s limits compare to Olympic, Glacier and Yellowstone; on this list Rainier is one of the tighter parks.

Timed entry and reservations#

Cougar Rock is on Recreation.gov with the usual six-month rolling window; July and August weekends go fast, midweek is easier. Separately, the park has operated timed-entry vehicle reservations for the Paradise and Sunrise corridors in peak summer. A campground reservation has generally satisfied the entry requirement for the corridor you are camping in, but the rules and dates change annually — read the current NPS “timed entry” page before you go rather than relying on last year’s setup.

Power, water and dumping#

Every in-park site is dry, generator hours are short and Loop E at Cougar Rock is generator-free, so solar and batteries do the heavy lifting; our RV power without hookups guide sizes a system for a three-night stay. Fill fresh water at the campground spigot, and because the Cougar Rock dump station is closed, plan a dump at your gateway park or a commercial station on the way out.

Best time to camp#

Cougar Rock’s late-May-to-late-September season lines up with the mountain’s short summer. Snow at Paradise (5,400 feet) commonly lingers into early July; the wildflower peak is late July through mid-August, which is also the busiest, most reservation-competitive stretch. September brings clear skies, thinner crowds and cold nights. If your goal is wildflowers, book the first week of August six months ahead; if it is solitude, the last two weeks of September.

Where Mount Rainier ranks#

Rainier does not make our shortlist of the best national park campgrounds for RVs on infrastructure — no hookups, no showers, no big-rig sites — but Cougar Rock is on it for location: few campgrounds anywhere put you 20 minutes from a trailhead like Skyline. Treat it as a two-night mountain stop between hookup stays, not a week-long base.

The bottom line#

For 2026, camping on Mount Rainier in an RV is Cougar Rock or a gateway park. Cougar Rock: 35-foot RV, 27-foot trailer, $20, no hookups, Recreation.gov. Ohanapecosh is closed all year, White River is small-rig and first-come and was fire-closed when we checked, and Mowich Lake is tents only. Ashford is the hookup base for the Paradise side, Packwood for the southeast.
