Is Fort McHenry free? Most of it is
The fence is the fee line
The Park Service is unusually precise about this, and the precision is what people miss. The fee area is the star fort and the outer battery, designated by a wooden fence. Not the park. Not the waterfront. The fence. Stand outside it and you owe nothing; step inside it and you are in the part an adult ticket pays for.
So the honest way to picture Fort McHenry is two places sharing an address. The larger one is a free 43-acre waterfront park in Locust Point with paths, grass, a seawall and a view across the water. The smaller one is a brick fort in the middle of it, and that is the $15. Plenty of visitors do only the first and go home content. That is not cheapskate behaviour, it is just what the park is.
Costs nothing
- The grounds, the lawns and the paths
- The seawall and the water views
- The visitor center
- The film
- Anyone aged under 16, everywhere in the park
Inside the fee area
- Inside the star fort
- The outer battery
- Anything else inside the wooden fence
The two hours nobody writes about
Between Memorial Day and Labor Day the grounds open at 7:00 a.m. The registers that sell star fort entry open at 9:00 a.m. For those two hours there is nothing to buy and nothing to queue for; the seawall and the grass are simply open. I have never seen a guidebook mention it. In a Baltimore July it is also the only civilised time of day to be out there.
The catch is at the other end. Last entry is 4:45 p.m. on weekdays and 5:45 p.m. at weekends, and the star fort, visitor center, gift shop and restrooms all shut 15 minutes before the park itself. Turn up at ten to five on a Tuesday and the free part is all you are getting. Full timings on hours and closures.
If four adults are travelling together, do the arithmetic before you reach the register. The $45 annual pass covers the holder plus three adults for twelve months, which is less than four single tickets on the day.
Who pays nothing at all
Under-16s, everywhere, always. Everyone, on eight named days in 2026. And every visitor, every day, for everything outside the fence. A single adult ticket is $15 and the receipt is good for seven days, so a Saturday visit still works on the Wednesday if you want to come back for the free half twice and the fort once.
What no amount of money buys you here
Two things, and they catch people out in different ways. The first is the flag: the original Star-Spangled Banner is not at Fort McHenry, it is in Washington, and the museum that holds it does not charge. See where the flag actually is. The second is a ticket: there is no third-party Fort McHenry admission product. Nothing sold on any booking platform gets you through that fence. You buy at the gate, from the Park Service, or you do not go in.
What works
- Most of the 43-acre park costs nothing, including the visitor center and the film
- Under 16 is free everywhere, so a family with young children may pay nothing at all
- The grounds open two hours before the registers, and the seawall is at its best then
- One adult ticket lasts seven days on the same receipt
Worth knowing
- The fee area is small: the star fort and outer battery, and that is the whole of it
- Arrive after last entry and the paid half is closed however much you want to pay
- Winter grounds hours are not stated in our sources, so check before an off-season trip
- No tour sold online includes admission — the ticket is the Park Service’s
What you can actually book in Baltimore
The closest thing to a Fort McHenry tour that exists is a 45-minute Inner Harbor sightseeing cruise, which names the fort as a sight and passes it from the water. There is no stop and no landing. None of it includes entry to the star fort. That is a National Park Service ticket, sold at the gate and nowhere else.
Frequently asked questions
Can you walk around Fort McHenry for free?
Yes. The fee area is the star fort and the outer battery, marked off by a wooden fence. The rest of the 43-acre park, including the grounds, the seawall, the visitor center and the film, is free to everyone.
Is Fort McHenry free for children?
Anyone under 16 pays nothing, anywhere in the park, including inside the star fort. The $15 entrance fee applies to adults aged 16 and over.
Is there a time of day when Fort McHenry costs nothing?
Between Memorial Day and Labor Day the grounds open at 7:00 a.m. and the registers that sell star fort entry open at 9:00 a.m., so for those two hours the free part of the park is open and the paid part is not selling.
