The campground was clean and felt safe. The campground host worked very hard to keep people from speeding and looked after everyone and was beyond helpful and kind. Very quiet at night.

This campground is in a wonderful spot and has great potential. Over the past 2 years we've noted the facility upkeep and improvement has been neglected. Other state and federal sites in this part of the country have invested in site improvement, but this location appears to have been overlooked. The negative issues primarily reside withe the latrines and bath houses.

Club Med of Ace campgrounds, though a bit dated, spotlessly maintained. Garbage cans at every site, with a crew who, empties garbage cans, and cleans leaves and debris off unused sites daily. Has big playground for kids, with bench swing chairs for mom and dad. a well-manicured sand volleyball court next to playground. an older, but fenced basketball court (can set up 2 pickle ball courts in it). A small boat launch in campground with fish cleaning station and ample parking for camper's boat trailers. (this launch is a bit small). however,. 1/2 miles up from campground in the day use area is a huge boat launch (park property) that will put in the biggest of Bass boats. No marina or piers to say, just a small tie off, so you really can't leave your boat in the water, but campground has 2 shallow tie offs, although not Shure how deep. Day use area has large beach and plenty of individual use areas along river, with a couple of larger pavilions with parking. Not far from Nashville, (1 hour) and plenty to hike and see in local area, entrance to a wide trail that runs along river to Ashland city, a few miles to the south. All and all a great campground, day use area, a little off the beaten path, but well worth the effort to visit. It is on my list of stay again campgrounds.

Great place to stay and relax. Plenty of shade combined with wind off of the river makes it comfortable even when temps are high. Park attendant one of the nicest we have every been around at a COE campground.
