Lincoln Rock State Park is an 86-acre public recreation area on the east side of Lake Entiat along the Columbia River in central Washington, north of Wenatchee and near Rocky Reach Dam. Set opposite the cliff formation from which it takes its name, the park offers broad views of the river, the south end of Swakane Canyon, and Turtle Rock Island, a 150-acre nature preserve. The island was separated from the mainland when Lake Entiat was created in the 1960s, reflecting how hydroelectric development reshaped this stretch of river. Today the park supports fishing, boating, swimming, picnicking, camping, hiking, and field sports.
