Nice State Park. Stay Away from Freeway.
Great state park with all the usual amenities: fire pits, trees, ranger station. It's basically two different types of campgrounds in one: there's the sites more out in the open that are closer to the freeway. Then there's a bunch further away in both a meadow and the woods. Obviously if possible, stay away from the freeway. Down at the day use area (which has a nice small beach) the sound was so loud it was hard to hear people talking just a few feet away.
Lots of hiking including a nice trail between the campground and the day use area. Firewood available. Spots for both camps and trailers including electric and water hookups. Nice staff/rangers available for questions. Walk-in spots are cheapest and many are further away from the freeway. Very clean overall.
