Campgrounds and RV parks near Olympia, WA

Day-use activities cluster around water, forest, and the capital. At Millersylvania State Park, families swim at two beaches on Deep Lake, paddle hand-carried kayaks and paddleboards, and walk miles of forested hiking and biking trails through old-growth cedar and fir. Volunteer-led interpretive walks are offered during the summer months. Offut Lake Resort centers on dock fishing on an electric-motor-only lake stocked with trout, bass, and perch, with a lakefront restaurant on site. American Heritage Campgrounds adds family amenities geared toward kids. Off the campground, Olympia itself offers the State Capitol Campus, Hands On Children's Museum, Tumwater Falls Park, and the Nisqually wildlife refuge. Mount Rainier and the Olympic Peninsula are both reachable as day trips.

Olympia's camping season runs strongest from late May through September, when rainfall drops sharply and daytime highs sit in the mid-70s Fahrenheit.

Sites near Olympia are generally wooded, with tall Douglas fir and cedar overhead. Expect filtered sun, soft ground, and the chance of moss on tables and pads. Cell service is inconsistent under heavy canopy, particularly at Millersylvania State Park. RV length matters at the state park: standard campsites limit total vehicle length to 35 feet, trailers over 18 feet are not permitted in the standard loop due to narrow roads, and utility sites accommodate RVs up to 60 feet with limited availability. Partial-hookup sites with 30-amp electric and water are available, and a dump station is on site. Private parks such as American Heritage Campgrounds and Offut Lake Resort offer full or partial hookups; pull-through availability varies. Bring layers for cool evenings even in summer, rain gear in the shoulder seasons, and a leash for dogs. Firewood gathering is prohibited in state parks; buy bundles on site.
