Established before the turn of the 20th century, Mount Rainier National Park in Washington is the fifth-oldest national park in the U.S. Although it's considered an active volcano, the last eruption was more than 1,000 years ago. Mount Rainier is open year-round and saw more than 2.4 million visitors in 2025. Across the white-capped peaks and origins of several major rivers, you're bound to encounter minks, elk, martens, bobcats, black bears, red foxes, mountain lions, black-tailed deer, moose, and mountain goats. While RV camping in Mount Rainier National Park, explore must-see locations like Glacier Bridge, Westside Road, Christine Falls, and Ricksecker Point Road. Harvest Hosts has plenty of locations within an hour of the entrances where you can park your RV overnight at a working farm, brewery, or distillery.
Harvest Hosts is a membership program for RV camping: unlock unlimited overnight stays at thousands of locations.
Learn MoreAlthough Mount Rainier National Park's wildflower population doesn't reach full bloom until the first of August, peak visitation begins in early summer. On the weekends and holidays, wait times at the entrances can be well over an hour. Nisqually and White River entrances tend to be the busiest, but even the parking lots in Paradise and Sunrise reach capacity before noon. During the winter, Nisqually is one of the only entrances that remains open to vehicles, but most inner-park roads are closed. The park closes Sunrise, White River, Ohanapecosh, and Stevens Canyon Road around the end of October but reopens them around June. Spring and autumn tend to be the best times to visit Mount Rainier National Park, but if you come during the summer, arrive before 10 a.m. or after 3 p.m. to avoid most of the crowds. Be aware that each entrance to the park only connects to certain areas, and that traveling between entrances to cover everything on your itinerary could take several hours.
Just southeast of Tacoma, Washington, Mount Rainier National Park is about a three-hour drive from Olympic National Park. Gateway cities include Eatonville to the west, Elbe and Ashford to the southwest, Packwood to the south, Cliffdell and American River to the east, and Greenwater to the north. Travel directly south to visit Mount St. Helens, the Mount St. Helens National Volcanic Monument, and Gifford Pinchot National Forest. To the west of the park is the Northwest Trek Wildlife Park. A must-see if you're RV camping in Washington, this park features electric trams and multiple species of animals.
Inside the park. RV camping in Mount Rainier National Park is available at two of the park's three RV-friendly campgrounds: Cougar Rock and White River. Once renovations are complete on Ohanapecosh Campground, it will reopen for visitors and RVs up to 32 feet. Camping in Mowich Lake Campground is restricted to tent-only. Cougar Rock Campground allows RVs up to 35 feet and is typically open from late May through the first of October. While Cougar Rock campsites can be reserved in advance, all of White River Campground's are first-come, first-served. White River restricts RVs to 27 feet and is open from early June through the first of October. Neither campground offers hookups.
Tips on reserving a campsite. Parts of Cougar Rock and Ohanapecosh campgrounds prohibit generator use, so verify usage restrictions before reserving a spot or claim a campsite in White River Campground instead. First-come, first-served spots in White River fill up quickly on weekends, especially during the summer.
Camping outside the park with Harvest Hosts. Finding potential RV campgrounds in western Washington typically isn't a problem; aligning your stay with campsite availability requires more coordination. With no hookups in the park and several other popular Washington attractions to visit, many RVers opt to stay outside the park's boundaries. Avoid camping fees by staying with a local Harvest Host at their own working farm, distillery, attraction, or brewery. For example, check out a behind-the-scenes look at the Sandstone Distillery in Washington State, a premier Harvest Host destination.
