This campground is open from April 1– October 31 but you must make a reservation and since we were looking for a place to land at 4:30 pm on a Sunday in June with no reservations, it would not work for us. 

It is located on the Calamus River and near (two miles away) from the Calamus Reservoir and Marina. Sites are laid out in typical RV style and have a picnic table and full hookups (30 and 50 amp electric), fire rings, and picnic tables and are large enough to fit all sizes of RV.

When we were there last year, there was no restroom on site (the website still says it is coming soon so either there are still no restrooms or the website is not up-to-date). 

This campground bills itself as family-friendly. Rates are$45/night and some of them are booked for the season.
