Lock A campground is well-maintained and offers beautiful river views, spacious sites, and friendly hosts, making it an enjoyable place for camping. Visitors appreciated the cleanliness of the facilities, good connectivity, and access to water activities like kayaking. While the narrow and steep road to the campground and some dated bathroom facilities were mentioned as drawbacks, overall experiences were positive, with many guests eager to return.

We love this campground! The campsites are all concrete and very large. The views and activities on the lake are enjoyable to watch from the campground. There is swimming at the public beach, bike riding and walking along the Bicentennial Trail connected to the campground. We didn't use the bathhouse, but I think that they are clean and sufficient. Would love to see the campground upgrade to offer a solid Wi-Fi solution. I noticed that Cumberland Connect has fiber on the pole adjacent to the check-in house. It would be pretty easy to distribute a good Wi-Fi signal throughout this fairly small campground. Would make it even more attractive for those that camp but need to stay connected to work or use it for entertainment.

Lock A is our favorite campground in Middle Tennessee. The grounds are maintained nicely, the majority of the sites are well-shaded and all are level. Ms. Cheryl, the camp host, is a very friendly and helpful lady.
My only criticism is that the hand air-dryers in the women's bathhouse are very outdated and do not work very well.

Campground was beautiful and the staff there was very helpful. We had no problems pulling our camper into the spot. The campers there all were very nice. We will continue to camp there.

What a great little campground and park! This park had wonderful views. Our site was tucked away from the river but offered some peace and quiet from the busier part of the campground. Our site was very level and long enough for our motorhome and tow vehicle. It had electric and water only. The sites by us were fairly spacious and partly shaded. Each site had its own garbage can which was emptied each day. The staff was very friendly and helpful with checking in. We did not use the restrooms so we cannot comment on their cleanliness and functionality. This campground was almost fully occupied during our stay. I can see why. It's a gem!
