We stayed at High Falls State Park 2 weeks ago on a Thursday.When we checked in,we were going to stay in the Lakeside Campground,but after looking it over,we found out we didn't fit in any of the available sites.Even though some were long enough,you had to back in at a right angle with a drainage ditch on each side making it mission impossible. So we went back to the office and they directed us to the Riverside Campground where there plenty of large sites.If we had reserved a specific site ahead of time,we could have been out of luck.
