A quiet stretch of the Potomac River in Maryland just became the newest national marine sanctuary, and it holds the largest collection of shipwrecks in the Western Hemisphere.
Roughly 200 vessels rest in its shallow waters, most of them wooden steamships built during World War I.
The designation, finalized by NOAA in 2024, covers about 18 square miles near Charles County.
Here's the money angle that matters for anyone planning a trip: visiting is completely free.
There are no gates, no parking fees, and no tickets.
You launch your own kayak or canoe from Mallows Bay Park, which charges nothing to enter.
The ships were part of an emergency wartime fleet ordered by President Woodrow Wilson.
When the war ended faster than expected, dozens of half-finished steamers had no purpose.
They were sold for scrap, towed here, stripped, and burned to the waterline.
What's left are ghostly ribs poking above the surface, now overgrown with trees and marsh grass.
The wrecks became artificial reefs and nesting grounds.
Bald eagles, ospreys, herons, and turtles now treat the hulls as real estate.
Kayakers paddle through a maze of decaying bows and boilers, often within arm's reach of a hundred-year-old engine block.
Spring and fall bring the best paddling weather and the fewest bugs.
Summer means heat, humidity, and aggressive mosquitoes.
Water levels shift with the tide, so check a tide chart before launching.
Some wrecks sit just inches below the surface and can scrape a hull.
Bring your own kayak or rent one from a nearby outfitter, where rates often run $40 to $80 for a few hours.
There are no concessions or gift shops at the park, so plan your snacks in advance.
The sanctuary designation doesn't ban recreation.
Fishing, paddling, and even some diving remain allowed under NOAA's rules, though anchoring on the wrecks is restricted.
That's a win for budget-conscious travelers who want a national-park-level experience without the entrance fee.
Mallows Bay sits about 30 miles south of Washington, D.C., making it a realistic day trip for millions of people.
A tank of gas and a packed lunch could cover the whole outing.
The site also draws history buffs and photographers chasing sunrise shots of the skeletal fleet.
Local guides lead occasional group paddles, and Maryland's park service runs free ranger programs on select weekends.
For families watching every dollar, it's a rare find: a nationally significant landmark that costs nothing to see and sits within driving distance of a major metro area.
My take: Widows Bay is the kind of free, weird, genuinely memorable outing that's getting harder to find.
Skip one overpriced weekend attraction and paddle through a graveyard of ships instead.
Final Thoughts
Just bring bug spray and check the tides, because the river doesn't hand out refunds.
