We live locally and travel nationally.   Who would have believed this great park would be only 30 miles away.  The grounds are very clean and well maintained, the sites are very wide and individual with the landscaping aiding the feeling of "private".  There, of course, are never enough full service sites but enough with good planning.  In Indiana, INDNR, allows for advanced reservations with a maximum stay of 14 days.  $7 at the main gate + camping fees get you access, unless you have membership, into any state park.  Go to the website for full details https://www.in.gov/dnr/state-parks.  The bath houses are always clean and well maintained.  Importantly, feel safe as the grounds all have a host and are well patrilled.  Charlestown is a model for both public and private camp grounds east of the Mississippi.  Lots of nature trails.  We recently watched two doe's with their 4 young fawns grazing while we ate breakfast.
