We've visited this campground twice now, and had a great experience both times.
The sites themselves are all in the open, imagine parallel parking your rig off the side of a road, with a nice forest behind you. That's kind of the deal here. But with room to fit another camper or two in between you and the next rig. Way easy access, but not a ton of shade or privacy. Sites are mostly level, but some did slant quite a bit. Hookups are well located and modern.
The facilities are very nice. Bathrooms are new and clean, and well kept. Showers were great. I've heard they've installed a new pavilion for games and events, but I haven't seen that yet. The staff is great, they have a nice little store for the basic supplies and treats, as well as fire wood and boat rentals. They also have cabins which are well thought out and nice!
Not a lot of Con's come to mind when I think about Lebanon. Very nice place, check it out!
