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 go here several times a year as it is always an enjoyable experience. The campsites are large and always clean and trimmed. There is plenty of hiking and bike riding areas for entertainment or you can just sit outside and watch the river barge traffic sail by. Bathhouse is always clean and easily accessible. Campground host always meets you and is available. All around great camping experience.

This is always our favorite stop of the year. Right on the Cumberland River. The girls love riding their bikes and it’s a one way in, one way out place so that allows us to feel much more secure. There are deputies that drive through multiple times per day. We enjoyed our bike riding this year down to the dam and back (about 4-5 mi). There are no sewer sites here but having a waste toter clears that up. Great place for anyone, would absolutely recommend.
