Took my Grandson there for his first overnight in a tent. We had a blast. The "Primitive Campground " area is where we stayed. It was about $30 for 2 nights.
The site had a gravelled pad, the size I'm guessing at about 10' x 18', on which you pitch your tent. There was also a table with bench seats big enough for 6 people, a fire pit, a wood grill, and a post to hold a lantern.
There was no electricity or water tap at the site, but there was a toilet facility, a hut with firewood, and a water spigot located within a short walking distance from us.
The campsites are numbered, and you can drive up to it.
There is plenty of information on the website regarding walking trails, etc. The office was actually closed due to staffing issues on the Saturday that we arrived, but there was a kiosk outside that had free maps and information. Later that day a Park Ranger came to our site to check on us and explain the rules.
Even though the night was very cold and the wind was wicked on the shoreline when we tried fishing, lol. We had a great time, and will be going there again lots more.
