Introduction

Eight miles to the south of Washington’s capital, Olympia, Millersylvania State Park occupies 903 acres of immensely scenic natural exhibits within 2,005 square kilometers of Thurston County. The park’s most prominent feature is the 66-acre Deep Lake which is a popular fishing spot and is well-stocked with rainbow trout, largemouth bass, bluegill, pumpkinseed, and yellow perch. RV camping opportunities can be found on the eastern shores of the lake while simultaneously enjoying the scenic beauty the surroundings have to offer. Other natural features of the park include cedar and fir forestations, 16 miles of scenic hiking and biking terrains, and a wide variety of unusually striking flora and fauna. The park’s property was sold to John Miller who, along with his family, named it “Miller’s Glade” but later changed it to Millersylvania in 1921 while giving away the property to be used as a state park. The remnants of the 19th century can still be found in the park in the form of skid roads, logging industries, railway systems, making the park a historically significant site. The park was also reportedly home to a rare species of freshwater crab, now gone extinct due to overfishing.

Established in 1935 by the Civilian Corporation Corps, the park offers many recreational opportunities like fishing, swimming, boating, hiking, biking, picnicking, outdoor sports, and the best of all, RV camping. The park’s campground is abounding with partial hookup sites for RV campers. The park is open for camping and other activities during the spring, summer, and fall, which make up the peak season months. During winter, relatively fewer camping facilities are available but the park stays open for day visitors. So what are you waiting for – make your RV reservations at Millersylvania State Park today.
