About Lock A
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.

FAQ
How do I get a reservation at Lock A?
Reservations for Lock A are made through Recreation.gov. 688 of 1,452 tracked site-nights are currently open (47.4%). Campsite Sniper has also detected 407 site openings here in the last 90 days, so further dates may appear. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Nov 2, 2026 18:20 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
How often do new openings appear at Lock A?
Campsite Sniper detected 8 site-date openings at Lock A in the last 7 days, 173 over 30 days and 407 over the last 90.
Can I get a multi-night stay at Lock A?
53 three-night openings are showing, counting only runs where the SAME site is free for all three nights. The soonest starts Apr 1, 2027 at site 06. Confirm and book on Recreation.gov.
Which sites at Lock A fit a 35-foot RV?
21 of the 44 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 40 ft. 37 of those 44 sites have a recorded maximum length and 7 do not; they are not counted as fitting.
Which month has the most availability at Lock A?
April 2027, with 599 open site-nights in the current snapshot of 1,320.
How far ahead of a stay do openings appear at Lock A?
Half of the openings Campsite Sniper detected appeared at least 5 days before the stay date; the middle 50% landed 2-9 days out. Campsite Sniper can monitor future changes for dates you select.
When is the next open date at Lock A?
Campsite Sniper cannot answer that from the current snapshot. The availability data held for Lock A begins Apr 1, 2027 — about 150 days after this snapshot was taken, so any earlier dates are outside what Campsite Sniper is tracking here rather than known to be unavailable. Check Recreation.gov for dates before Apr 1, 2027.
