Campground here has both electric sites for campers and primitive sites for tents. All are shaded and quiet. Showers/bathrooms are really nice and clean. In addition to campgrounds, there's a very nice lodge with a good restaurant, and the cabins here are pretty good too.
Lots of amazing, beautiful hikes in this park, especially if you're into bluffs and large boulders. Easy drive to many other picturesque and unique parks (i.e. Garden of the Gods, Ferne Clyffe), and easy drive into town if you want something more civilized.
Kind of a bare bones campground but this state park does offer rock climbing (if you have the expertise and your own gear). A few picnic shelters and an amazing CCC lodge that has a cabin rentals and a pretty good area restaurant. The park used to have an interp center but I believe the state closed it do to funding. The trails aren't always maintained it definitely depends on the season but the park itself is not to be missed.
There's about 80 total sites, ranging from electrical hookups to primitive (there's about 15 of these). You can reserve, or walk-in. I went in October and didn't need a reservation. I also chose primitive. Showers and bathrooms are available to all, and sites have fire pits. You're most likely looking for a camp + hike adventure, and there's a trailhead for Red Cedar Trail off the site grounds. It's about 6 miles in a large loop, with one stop along it taking you to a primitive Red Cedar Campground, which is like a bunch of old tee pee looking structures. 3 stars because although this hiking is beautiful in the fall and the amenities are decent, the trail itself is tricky. It does have markings, which keep you on the trail, but there's no way of knowing how far along the hike you are, or how long the hike even is (I learned later it was 6 miles from the website). It would be nice to see sign posts or mile markers to give you some idea how your hiking pace is. It's a great place with the fall colors to go and explore, but plan your hike with enough time to not get caught in the lower amount of daylight. Hike is about 2-4 hours, depending on your pace. I suggest photos of the trailhead signs before you set out.
