Maryhill State Park is a public recreation area on the Columbia River in Washington. Covering 81 acres with about 4,700 feet of shoreline, it serves as a riverfront base for camping, hiking, boating, fishing, and swimming. The park is also near Maryhill Stonehenge, a full-scale concrete replica of Stonehenge set on a nearby bluff. Together, the park’s shoreline setting, outdoor activities, and proximity to this unusual landmark make it a notable destination along this stretch of the Columbia.
