Weather at Millersylvania State Park

Best Time to Camp at Millersylvania State Park

Summer brings the best conditions. Daytime highs in the mid-60s to mid-70s°F, nights in the 50s, and reliably dry weather that opens up the full lake experience: swimming, boating, paddling. The tree canopy keeps campsites shaded and comfortable even when valley temperatures climb. Holiday weekends (Memorial Day, July 4th, Labor Day) see the heaviest crowds and the most amenities open, including the snack shack and boat rentals. Late summer occasionally brings wildfire smoke from elsewhere in the region, reducing air quality and views for a few days at a time.

Summer(Jun-Aug)

4.0 / 5

Summer is best: mid-60s/70s, dry weather and full lake/beach/rental operations draw crowds.

Planning Tips

About Millersylvania State Park

Millersylvania State Park sits on a calm lake 30 minutes south of Olympia, offering 149 campsites (tent, RV, and group), 8.1 miles of trails, two swim beaches, and kayak rentals. The park's tall conifers provide natural shade that keeps sites cooler than surrounding lowlands. Expect crowds and noise on summer weekends. This is a popular family destination where the snack shack, boat rentals, and beach atmosphere draw repeat visitors.

Campground supports tent and RV camping and has facilities and rentable buildings suited for groups.

Late summer occasionally brings wildfire smoke from elsewhere in the region, reducing air quality and views for a few days at a time.

Natural Features and SceneryThe campground sits beneath a canopy of towering Douglas fir and western red cedar, filtering sunlight onto a forest floor thick with ferns and salal. The lake is the centerpiece: glassy, calm water ringed by evergreens, with two sandy swim areas and easy put-in spots for kayaks. Elevated boardwalk sections protect the understory on some trails, which loop through dense woodland where moss drapes older trees. At 220 feet elevation, the forest stays noticeably cooler than open valley sites during summer heat.

Scenic ViewsWooded lakefront views, shaded forest trails, boardwalk sections through old-growth areas, and lake beach views from swimming/boating areas.

Best CampsitesReviewers single out sites 35, 46, 55, 57, 61, 64, 66, and 76 as more secluded options with better spacing. Lakeside and beach-adjacent sites are popular but offer little privacy and can be noisy on weekends. Sites 47 and 49 have been flagged for occasional sewage odors. Worth checking current conditions before booking those spots.

Go if

Summer lake trips with kids who want to swim, paddle, and hike easy trails. Sites 35, 46, 55, 57, 61, 64, 66, and 76 offer the most separation from neighbors, book them first, and book midweek if noise is a concern.

Skip if

Holiday weekends are genuinely loud: late-night music, car alarms, and little buffer between sites. Reviewers also flag occasional sewage smells near certain sites, and fees have reportedly crept past $40 a night.
