I've stayed here in the past and Cowan Lake does not disappoint. The B site campground is all non-electric tent camping, and far enough away from the larger RV pads that it's a quiet little campsite! Also, these sites are super close to the bathrooms on the beach, which were very clean during our stay. I was incredibly impressed, because the beach gets pretty busy during the day. The beach itself was clean (for a lakeside beach- there are geese, it's Ohio) and the lake was gorgeous! I will say, the only MILD annoyance is that some of the other campers would drive to the parking lot in front of our campsite and park there into the evening hours to fish or head down to the docks. I'm an early riser, so the headlights and car doors slamming were mildly annoying after about 10p. Not enough to make me choose a different campsite, but worth noting. We rented a tandem kayak and explored the lake, and the equipment was all in good condition. The Commisary is pretty limited but they do have a small kitchen and ice cream, as well as the basics like firewood and ice, as well as the boat rentals. Overall, one of my favorite lakeside campgrounds!
