www.doorcountycampgrounds.com lists many available. Tranquil Timbers RV resort in Sturgeon Bay is nice . Quietwoods South in Southern Door County, great family park. Southern Door County is ecomomical and only an hour drive to the tip of the Door. Great place to visit "The Door County Peninsula in Wisconsin", sometimes called the Cape Cod of the Midwest! Don't miss the Fish Boil! Also, Five state parks, Peninsula State Park has camping available. Check the state website. Have a great time and maybe we'll run into each other.
