Geneva on the Lake State Park- Ohio
I recently spent 4 days/3 nights at Geneva on the Lake State Park. I had gorgeous weather. Campground was maybe 15-20% full ( I was there mid week). They have two loops, one being more open and the other more wooded. I stayed in the wooded one and it was quite nice. Although, I had no rain, I can see where the wooded loop would have some drainage issues during a hard rain though.
Nice 2 mile bike trail that leads down to the marina and the lodge beyond. The "strip" in the adjacent little town of Geneva on the Lake was all but closed down but fine by me.
I may go back next year and somehow bring my boat with me and stay for a couple weeks to enjoy the fishing there on Lake Erie.
