Sebago Lake State Park is a 1,342-acre public recreation area on the north shore of Sebago Lake in Naples and Casco, Maine. Opened in 1938 as one of Maine's original five state parks, it remains a heavily wooded lakeside park managed by the Maine Department of Agriculture, Conservation and Forestry. The Songo River divides it into east and west sections. Two campgrounds, Naples Beach and Witch Cove, provide 250 campsites, beaches, and boat ramps, while a day-use area, hiking trails, and biking routes broaden access. Set on Sebago Granite, the park has long been a notable public outdoor destination on Sebago Lake.
