The Lock A campground is not the largest, nor is it located next to some of the favored destinations in the world. But it is one of the best kept and managed campgrounds we have visited.
In combination with the entire Cheatham Dam facility, it offers a lot of things for families to enjoy - water, fishing, biking, walking...even just chilling.
The sites are spacious, and extremely well kept...the staff is friendly - even had a great conversation with the guy picking up trash one morning.
As I said, it isn't in the middle of a bustling tourist area, nor is it a large park with clubhouses and game rooms...but it is close to Nashville and Clarksville, there are restaurants within minutes if you need them and it is an incredible site for families and a quiet getaway.
stop by if you are close...it will not disappoint.

Very clean place, the huge concrete pads with picnic table and firepit were a plus! The campsite host was absolutely amazing! Im a new solo female camper and she hyped me up. Helped me back in when I was nervous and really made me feel like a superstar when she didnt have to do anything! Ill definitely be returning. I wish I could have a permanent spot here!

We frequent Lock A for our trips. This was our first stay this year and the camp host was the friendliest, nicest, most helpful one we have ever encountered. She is a true gem!

Such a magical, beautiful campground! Sites are spacious and well-maintained, and facilities are adequate. The long road running along the river is perfect for walking the doggo. If you're a nervous driver like me, the steep descent into the campground is a bit scary. Worth it though!

Site 24 is our favorite Site at Lock A. One of the first sites to be reserved. Feel lucky any time we can get it. Staff and Rangers were great.

Host was great always making sure sites have everything needed. Our electric wasn't working. Maintenance came to fix and he was friendly and made sure we had electric until he could get the part to fix the next day. Highly recommend Lock A. We will be back again

Overall a great visit. Easy access hiking with views of the rocky bluff and river. Tennis court and basketball court was nice. Shower house was clean, but only one shower each for men and women.
Sites were very level. Tent sites looked clean and level as well, with designated tent area.
The Hill in was 1/4 mile long steeeep winding road, paved and well maintained. Take it slow (20 mph speed limit) and you'll be fine! We saw plenty of wildlife, and at night the camp was quiet! We'll maintained! We will be back!

Nice park on the river. Enjoyed watching the barges travel through the lock. Well space sites and camp host very considerate making many rounds of the park daily. She made sure that we were aware that thunderstorms would be moving through alter that night. All around a very nice COE park. Don’t use the bath/shower so can’t comment.
