We live close to this park and frequent there, sometimes just day trips. Tent camping is great and just like most places there are a few sites that are the best. Park offers hiking trails from the camp sites to the beach area or packing up the swim gear and using the parking lot. The beach area is back water from the ohio river. It is a sandy rocky mixture. There are boat rentals during peak months. There is a frisbee golf course that is top notch. The only down side to this ohio state park, are the bathrooms; they are port a pot facilities that can be pretty raunchy.
I have stayed at this park numerous times, in tents and camper. The history of the area is really interesting and if you're lucky enough to talk with the park manager he'll be happy to give you a little house coal history. I've heard rumor however that the park is losing funding. Great hiking and biking trails. Loved going through the creek!
