About
Overview
The relaxing yet activity-rich Lock A Campground has something to offer everyone from horseshoe pits to volleyball courts and hiking opportunities, plus a plethora of lake activities as well.
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.
Recreation
The temperate climate here allows for a lengthy recreation season including boating, swimming, canoeing and fishing.
For hikers, the Cumberland River Bicentennial Trail is a rails-to-trails project, which runs 6.5 miles long and crosses Sycamore Creek on a historic abandoned railroad trestle.
Facilities
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.
Nearby Attractions
The Pardue Pond and Dyson Ditch Wildlife Refuges are on the other side of Cheatham lake. Both are excellent places for bird watching and exploring.
