I had three nights reserved at my favorite site and had a great setup including a new canopy I had purchased to cover the table (a definite plus), and the first night was rainy and chilly, but some sun broke out a few minutes during the second day. The weather was pretty blustery, but I was prepared to stay the second night until a late afternoon weather app (Ventusky) check predicted a concerning pattern: It was going to rain, then rain some more, then pour down for hours with 100% chance of rain. I'm a retired old guy and I agonized for an hour or so about it, but finally decided to bail, primarily because it increasingly looked like if I stayed, I would be breaking down my tent camp in pouring rain. Not an attractive option. I went ahead and broke things down and packed them up, then sat in a camp chair by the fire until the increasingly heavy drizzle had doused it. Glad for the decision but missed the rest of the trip, and of course look back to the next one. The place is a magical one, the resident management is personable and helpful but not at all intrusive, and it's quiet and clean. My favorite pastime there is to sit in my camp chair and watch the light change on the surroundings, including a lazy section of the mighty Cumberland River. The adjacent trail is closed for bridge repairs and I look foward to its return to accessibility for hikes!

It's a beautiful, quiet campground right next to the Cumberland River. The staff was very friendly. We would definitely return.

We had a great time and this spot in particular was great for us as tent campers with stairs down to the water.

First time visit to Lock-A campground and I will come again. The campground was clean and well maintained. I had a tent site and was surprised to see concrete slabs or maybe just my site (39), but the view far out weighed the slab

Beautiful campground, with well maintained campsites along the river. The bathrooms need a little sprucing up. During our stay, the handicapped women's shower had no hot water but the regular shower did. We happened to stay on a day when no attendant was on duty and no phone number listed to get in touch with anyone if needed. All in all, one of our favorite campgrounds to stay at!

Lock A had nice clean camping spots and bathhouses. We loved the trails and especially the road that extends from the end of the campground all the way beyond the dam. It’s perfect for bike riding. The river spots look amazing and we’re hoping to experience one of those next time. We’re planning to return there often.

The restrooms were much cleaner than in past years. Keep up the good work! The weather could have been nicer without the rain, but we had a great stay.

The lady at the check-in building I think her name is Cheryl is always so nice to us. The grass is always cut neatly and the trash is removed from the cans frequently. This is our favorite place to camp, it is so relaxing there.
