Had a great time as usual at the Lock A Campground in Cumberland, TN.
Only wish they had sewer hook ups...

Site 15 has no lid on garbage can. Due to animals in area it makes the can unusable. It has been this way for a number of weeks. No excuse for this as the garbage is picked up on a reular basis.

The campground hosts are so nice and feel like friends. I’ve always loved this campground. The campground is beautiful, well maintained and the sites are spacious. Every site has a great view. I love to look at the water and watch the barges passing by.

We enjoyed the spacious campsite, Site 03, which easily accommodated my RV, Dodge 3500, and Ford Explorer. Shade and quiet made for a great visit. Driving into and out of the park on Cheatham Dam Road worked my truck especially hard because of the steep grade and my RV is 16000lbs. Also, be mindful of three, ninety degree turns on that two lane road if you are pulling a big RV (40'+).

Beautiful setting. Spacious sites. Very clean and up to date. River right at your feet. Moonlit night over it was gorgeous. Can’t wait to return.
