Cowan Lake State Park is near Wilmington, Ohio and they have been making a lot of improvements to the park. It is a great location between Cincinnati and Columbus with easy access from the highway. This is good if you want to meet with friends somewhat in between. It isn't too close to the highway so you don't hear the road noise as it is a few miles away but it is an easy drive to the park.
They have been revamping the Nature Center to make it more accessible to folks as they have recently added a ramp. The Nature Center actually has two buildings side by side used for different purposes. Then behind the Nature Center they have a location where several birds are located in cages. Then next to where the birds are kept you will notice a new paw print trail that is a short but informative hike.
The commissary has great pizza and ice cream. We also bought our firewood and ice from them as well. We didn't need to leave the park. We had a few trails to pick from and picked two of the shorter ones for members in our group.
The cabins have been revamped as well. They are all close to each other so if you wanted to have a family reunion or a get together this would be a great spot to do so. At the end of the main road it will lead you to the lake. You can use the dock to put your boat out (kayak and certain motor boats). Folks are fishing at the lake or simply enjoying the beauty of the lake.
The beach is simple but that is part of the charm. It is clean and we were able to swim on the hot days that we had while camping.
