Great park with daily, weekly, monthly rates. There is a mix of full hookups, electric and water, and primitive sites so try and reserve if possible. They have 2$ laundry, free showers, restrooms, firewood, a small store, restaurant, and really friendly owners that will accommodate you the best they can. There is also a dock on the lake to catch some rainbows!
A bit wide open and highway noise but on lake with laundry, showers, full hookups, firewood for sale, restaurant, matanuska lake access, long term parking too. Some sites have gorgeous lake views.
