This is actually two different campgrounds -- North and South. The North Campground has larger sites spaced a bit apart to afford you some privacy (or at least as much as you can expect at a state park campground). The grounds and facilities looked to be in good condition, too.
The South Campground (where we stayed) has smaller sites that were much more closely packed together. There are non-electric sites that are a bit deeper but still quite narrow so your neighbors may be right there when you look around. The facilities in this campground also seemed to be in good, clean condition.
The one thing that was bit unnerving was that throughout both campgrounds, there are sites on the outer edge that are next to a main road with nothing but a small, wooden split-rail fence dividing the state park from the outside world. While the park is in a rural area, it still seems odd to have zero security for your site and your belongings from anyone who just happens to park on the road and wander in.
This seemed to be a popular campground for families -- especially little kids on bikes, so be extra cautious when driving around or even riding your own bike because the kids seemed to have no concept of safely riding around. They would often change direction or dart out unexpectedly.
Things to do include a good-sized, no-wake lake that was a pleasure to use our kayak on. There is a small beach that seemed popular, although the signs warning about all the dangers in the lake made us question entering the water for swimming. There also is a hiking/mountain biking trail that goes around the lake. It wasn't well-marked and seemed to just be a series of connections through some woods, down roads, and across parts of the developed areas of the park. So, not a terrible experience but just not what we expected.
We rented a yurt as a local weekend escape. Our kids loved the yurt. It was nice with a little mini fridge and 4 double beds. Campground showers and bathrooms are clean. It is one of the only state parks in northwest Ohio, a beautiful little spot nestled in farmland of Ohio. The lake is nice for swimming and there are bike rentals which was fun as well. We did not use it, but there is a dog beach as well. Sites are crowed and close together.
Nice family campgrounds sites are roomy, asphalt, and generally level. Restrooms and showers are clean and well maintained.
Spacious site. Well maintained park. Clean, hot shower in north Campground. Lake is good for fishing, marginal for swimming. Great people at registration. Friendly and helpful host. Some good restaurant choices nearby.
We have been here a few times. Really enjoy the secluded sites and the lake. It’s a small campground but it’s clean and quiet. Most sites don’t have water hookups but they do have electric. There isn’t much to do outside of the campground but there is a nice lake with canoe and kayak rentals. Very pet friendly and even has a dog beach.
Tents are welcome, as well as big campers. Have a couple of cabins and yurts. A lot of groups camp here. Not a lot of kids activities, no pool, but does have a beach on the lake, canoe and kayak and paddleboaed rentals and trails for hiking. If you want a quiet retreat, this is usually the place.
It’s very clean and quite. Nice size sites.
love Harrison Lake. It is our go to if we don't have other plans. been there multiple times. Very clean and well kept. Lots to do. check it out and see for yourself.
