I stayed at Keyhole State Park for a few days last summer when the campground was about half full. Visiting in April turned out to be perfect as I enjoyed near-perfect weather, plenty of wildlife viewing opportunities, and managed to have an entire campground to myself.
I was literally the only person at the Homestead campground! After too many weeks of urban stealth camping, this was a wonderful respite.
