Dense Douglas Fir and Hemlock create a canopy overhead at this state park campground, where three distinct camping areas serve different needs. The forested tent loops wind through narrow roads beneath old-growth trees, while RV sites occupy a more open field with full hookups accommodating rigs up to 60 feet.
Deep Lake anchors the park's recreation, allowing only cartop boats that keep the water calm for paddlers and swimmers. Shari G. notes the lake is "super chill, shallow and warm," with rental kayaks and canoes available during summer months. A beer garden and snack shack operate seasonally, while group kitchens built by the CCC in the 1930s provide covered cooking areas for larger gatherings.
The campground's layout creates varied experiences depending on site selection. Tent sites tucked among the trees offer more privacy, though Susanna D. describes the overall atmosphere as "tightly packed and crowded." RV sites in the open field lack privacy but provide easier access and better solar exposure for panels. Site 202 sits separately from other spots but can catch odors from the nearby dump station when wind shifts.
Multiple hiking trails loop through the park, ranging from short walks to half-day excursions, with good signage preventing navigation issues. The campground stays busy, particularly during summer when the lake draws families between 11 AM and 6 PM. Winter operations reduce available sites to numbers 1-7 and 226-248, creating a quieter experience. Reservations book quickly during peak season, and muddy conditions can develop during Washington's rainy months.
Campers wanting lake access without crowds might consider Deep Lake Resort just down the road.
Description
Millersylvania State Park offers fun for everyone. Spend a summer day splashing in Deep Lake. Gather with friends in an historic kitchen shelter.
Conveniently located between Olympia and Centralia, this large, well-visited park beckons to adults and children alike.
Many of the park structures, including the kitchen shelters, were built by the Civilian Conservation Corps (CCC) in the 1930s, making the park a great place to see and admire the hallmark artisanship of that era.
With two swimming beaches, miles of forested hiking and biking trails, watercraft launches, non-motorized watercraft rentals (kayaks, paddleboards, pedal boats) and abundant fishing, Millersylvania will keep you busy for a satisfying weekend or an extended outdoor vacation.
