This state park/campground is definitely.. unique. Following GPS directions to this camping area led us into the park and to a locked gate. Drive beyond the gate and there's an open field to the left with one official 'campsite'. Continue to drive past, following the road around for about 1-2 minutes, and you arrive to the "campground" / "Frisbee golf course", where there's 10 spots, I believe, and a donation based toilet.
There was someone set up at the single site in the open field, but the campground was empty. There were hookups that didn't look like they functioned. Since there were blue signs with "camping" written on them, and arrows pointing to the open field, we pulled our van along the back behind some trees, where there was a cute spot with a picnic table, and access to "Lake Bottom Trail" which really looked like a mowed path around a hunting ground. There was also another trail or two in the area, but we did not explore them.
The air was filled with tiny black flies (though harmless) but dozens and dozens got caught in my arm, head, and leg hairs, and it was quite frustrating, but again they were quite small and harmless, but that was my main issue with the location.
Locals drove by a few times, as it seemed farmland and some houses are accessed through the park. The town of Oberlin has very limited food/supplies.
