Truly enjoyed our stay here. The trees were changing colors. The air had a nice crispness to it. We spent a decent amount of time looking for the geocaches around the area. We will absolutely be back.

Great place to ride bikes(paved bike trail) hike, camp, boat. They don’t make it easy to bank fish with loads of rocks and little to no sandbar fishing spots. Playgrounds are ok the playground by visitor center is excellent!

What a fantastic campground! Immaculate, a lot of wildlife, beautiful lake, and super helpful people at the gate. We travel back and forth from our home in Iowa to our home in the Georgia mountains and are always looking for state parks. I will say, this is one of the very best! Nice job!!!

Great campground on a beautiful lake. Sites are well spaced out, so your not on top of each other. Just make sure and read the comments so if you need a level spot you don't end up sleeping on a slope. Convenient to town if there is something you forgot or want to go antique shopping.

Very nice campground, beaver lodge loop is where we we at. Nice shower/restroom combo. Hilly in areas. Walking distance to lake. Right by the cove to float or kayak. Lots of bike riding paved trails.

Beautiful and well maintained park that was great for an overnight stop. Gravel pull thru with full hook ups. Quiet, clean and safe.

Our favorite campground in Illinois, everything in clean and well maintained, the tent sites (especially T-14 and T-08) are awesome. We love the lake and bike path.

We just got here and we like the place. Water and electric hookup. Right on the lake and on a very specious site. Most of the ACE campgrounds are very specious. The only negatives; does not have the full hookup (dump station on exit) and the sites are the most leveled. Otherwise, great place to stay in So. Illinois.

This was our 4th stay here for ten days and it was great! Beautiful trees and abundant wildlife, especially deer of all ages. Our dog was "skunked" on two previous trips, so beware of those stinky critters for your fur babies. Lots of hiking and just enjoying nature. We had #81 this visit and it was good. Fairly level and good view of Rend Lake. Our friends were in #82 had a great lake view, but site was absurdly unlevel. They had to purchase a fence post to prop under the tongue of the trailer and park diagonally. Spaces are well spaced and most had cement pads. They park is close to Benton for all your shopping needs. Would definitely recommend and hope to return.
