Raccoon Ridge Campground — Brown County State Park

Our third Indiana state park. Still impressed, they have all been friendly, well maintained with good, spread out sites and good signage everywhere (even the trails). All the rest rooms are spotlessly clean.
We were there mid-week, so very few of the 480 (!) sites were occupied, except in Buffalo Ridge, the primary RV loop. There are three loops, Buffalo ridge (RV), Raccoon Ridge which is tent sites around the outside, with electric inside the loop. Which would be suitable for RVs. Many of the tent sites are split-level, meaning the fire pit and tent area is down a hill from where you park your car. We have a mini pop-up, and had no problem parking both it and car on the pad, and, these sites have two picnic tables, upper and lower. Check the photos when you reserve!
We drove through Taylor ridge loop, and it's your best choice for getting away from it all. 
The camp store is stocked with the basics, but has more souvenirs than food or camp needs. That's okay, as some of their goods are better quality than many other places.
The park has a classic old CCC lodge (though you enter through the modern addition) so if you don't want to cook, eat at the restaurant (open till 8:PM), great food, generous portions. 
The park also features an Olympic size pool (capacity 2,000). You cannot walk there from the campground unless you are very hardy and very determined. 
You may think of Indiana as flat farmland, but this park is VERY hilly, with many scenic overlooks. It has two man-made lakes. Unsure about boating options on the larger one. 
Another big feature are equestrian trails and a horse campground, see someone else's review for that.
Nearby is the town of Nashville, which is full of art and craft galleries as well as multiple fudge shops, hand-made soaps, etc... Touristy but quaint. Was surprisingly crowded when we passed through on a Friday morning.   
We are planning to go back to take advantage of all we missed in the area. Oh, I should point out that there are many private campgrounds nearby, it's a very popular  area.

Tons of campsites and most have decent trees and privacy (even many of the electric/RV spaces looked nice). As tent campers, we stayed in raccoon ridge which was excellent (quiet). Pit toilets at the back of the loop were probably the cleanest pits I've ever used. Bonus that there are dedicated mens/womens pits. The shower house at the top of the loop was dated but completely adequate with hot water (works for me). The picnic tables in the park are a bit odd (very short) but was plenty of space for my husband and I. With larger groups, it might be difficult to fit everyone around the table. 

The park has so many activities. We visited the nature center which was nothing spectacular but still something nice to do. We also hiked on 3 of the trails and went up the fire tower. It's nice to have a bike to explore since the park is so big. I wish I was a mountain biker, the trails looked amazing and the park was packed with mountain bikers. 

We will definitely keep this park on our list of semi-local camping for weekend trips.

The Campground is on top of the Ridgeline. When we pulled in it was raining and there was smoky mist hanging over the forests. We set up camp and since there were no bugs first week of October we slept with the screen open on the tent. There is a new pit toilet by our campsite which was very clean. We didn't bother with showers because we are stinky mountain bikers. So I can't comment on the shower house. The ranger told us that all the deer had been killed by over hunting in the park, but when we drove back to the Campground after dinner there was a whole herd of deer hanging out at the camp ground. He also showed us how to find paw paw fruit in the woods which taste like a cross between a banana and a peach. Delicious. We only camped two nights but we had a lovely time. We rode the trails which were surprisingly dry and fun. We wanted to ride the flow trail HogsHollow but we didn't know how to get back up the mountain. It's 5.5 miles down and I'm not in good enough shape to climb back up. So maybe next time we go we can call for an Uber since it turns out it is available there. There is supposed to be 200 miles of singletract trails in the area plus horse trails. There is a horse barn for trail rides and also a horse camp. There is a lodge there too but I didn't have time to see it. Also a swimming pool and nature center. The town of Nashville is right there with lots of artsy shops and restaurants in rustic buildings. There are numerous hotels and a music venue and a playhouse. Something for everyone. Unfortunately the bike shop right outside the park went out of business. Can't wait to go back.
