Keep in mind, staff will hold a campsite until the check-out time (2:00 pm) on the day following the arrival date. However, if you're arrving late, we highly recommend you call the campground to notify the Park Attendant. If arrival does not occur before check-out time on the day following the arrival date, the reservation will be canceled.

Both RV and tent sites have 50 amp electric hookups. Additional amenities include hot showers, a dump station, boat launch, playground, picnic shelter and swimming area.

A beach and additional playgrounds are available in the adjacent Cheatham Dam Right Bank Recreation Area.

Natural Features

Lock A is on the north bank of the lake, just upstream from Cheatham Lock and Dam along the Cumberland River in north-central Tennessee.
