Lincoln State Park is usually packed. It’s less than 10 miles away from Holiday World. I think a lot of theme park visitors camp here. I’ve stayed in both electric and primitive. Bathhouses are kept clean and staff is friendly. Book online using Reserve America to make sure site is available.
Campground sites were a little on the small side. Bathhouse was better than other parks. Beach is easily accessible by walking trail. Sand dune trails are amazing!
