Set up your RV home base between the Olympic National Forest and Mount Rainier.
Situated on Puget Sound about 30 miles south of Seattle, Tacoma is one of the largest cities in Washington, offering easy access to Mount Rainier National Park, 60 miles to its southeast. It's a good alternative to Seattle if you want a more affordable RV camping base in the area, with wider, flatter roads and abundant parking. There are plenty of private RV parks right in town and elsewhere in Pierce County, the closest of which—Dash Point State Park—offers a mix of standard and utility campsites and a dump station, while accommodating RVs up to 40 feet in length. Public and privately owned options can also be found nearby in the Mount Rainier area in the surrounding Gifford Pinchot National Forest, and in the Olympic National Forest, east of the city. Standard RV amenities range from basic picnic tables and fire pits to full hookups, dump stations, and even wifi.
