We went Thursday - Saturday, and will go again during the week to avoid crowds.
The check-in process is a bit troublesome if you're picky about getting a good tent site- you can't reserve specific sites ahead of time. Also, your visit will cost you more than listed on the website because they charge entrance fees for each person on top of the campsite rental. That was an unpleasant surprise. The only other unpleasant surprise is that the campground store is closed on Thursdays. Lesson learned- bring your own Snickers!
However, the scenery, quietness, and availability of rental boats was wonderful. We camped in tent site #70, and I would grab that one again in a heartbeat. The 70's sites have water access and beautiful views, and are generous with their square footage. Plenty of trees down there to hang hammocks and clotheslines on, and more than one flat spot for tents on each site.
I normally would not devote a whole paragraph to restrooms at a state park, but I will this time. These were the CLEANEST restrooms I've ever seen at a state park, and the most updated. The stalls had modern dividers, the toilets all had clean, functional seats, the showers had separate bench areas with lots of hooks, plus normal faucets you could just turn on once (as opposed to having to push a button every minute), and the sinks also had great faucets with good pressure and reliable water temperatures. Very easy to use.
All our issues with this park were related to unexpected costs and logistics, but the park facilities were fabulous. We will definitely be back!
