You’re standing on a beach in Lewes, staring at the water, and you realize you can basically see another state. It’s a weird feeling. Delaware is tiny. So tiny that if you blink while driving down I-95, you might actually miss the entire thing. But being the "Small Wonder" means Delaware has a lot of neighbors packed into a very tight space.
Kinda like a middle seat on a crowded flight, but with better tax-free shopping.
When people talk about states close to Delaware, they usually just think of the big names: Maryland, Pennsylvania, and New Jersey. That’s the obvious trio. But there’s a nuance to how these borders work that most people totally miss. For instance, did you know Delaware technically owns a piece of the river all the way to the New Jersey shoreline? Or that you can walk from a Delaware beach into Maryland without ever seeing a "Welcome" sign?
It’s messy. It’s historic. And honestly, it’s what makes the Mid-Atlantic so fun to explore.
The Big Three: Who Actually Borders the First State?
Delaware isn't just "near" these places; it’s physically locked in by them.
Maryland: The Longest Hug
Maryland is the neighbor that won't let go. It wraps around Delaware’s southern and western sides. If you’re in Delmar, you’re literally in two states at once. The town is split right down the middle by the state line. You can buy your groceries in Maryland and walk across the street to get your hair cut in Delaware.
Most travelers head to the Maryland border for the beaches. Ocean City, Maryland, is just a few miles south of Fenwick Island. It’s a jarring transition. You go from the quiet, somewhat posh vibes of Delaware’s southern beaches to the neon-soaked, boardwalk-fry-smelling chaos of OCMD in about ten minutes.
Pennsylvania: The "Twelve-Mile Circle"
Look at a map. See that weird, perfect curve at the top of Delaware? That’s not a natural river bend. That’s the "Twelve-Mile Circle." It’s a geometric border centered on the courthouse in New Castle.
Pennsylvania sits directly north. This is the Brandywine Valley region. It’s where the du Pont family built their massive estates like Longwood Gardens (technically in PA, but basically a Delaware backyard) and Winterthur. If you’re in Wilmington, you can be in Pennsylvania faster than it takes to order a coffee.
New Jersey: Across the Way (Sorta)
New Jersey is to the east. But here’s the kicker: the border isn't in the middle of the Delaware River. Thanks to some 17th-century legal drama that went all the way to the Supreme Court, Delaware owns the river up to the low-water mark on the Jersey side.

So, if you’re standing on a pier in Pennsville, NJ, and you drop a fishing line into the water, you’re technically fishing in Delaware. To actually get there, most people take the Cape May-Lewes Ferry. It’s an 85-minute ride that beats the bridge traffic any day of the week.
Surprising Neighbors: Who Else Is "Close"?
"Close" is a relative term. In the West, a three-hour drive is a commute. In the Mid-Atlantic, a three-hour drive gets you through four different states and two different accents.
Virginia is the neighbor nobody mentions. While it doesn't touch Delaware, it’s right there at the bottom of the Delmarva Peninsula. You drive south through Delaware, hit the Maryland line, and about an hour later, you’re in Virginia. This is the "land of the wild ponies" (Chincoteague and Assateague).
Then there’s New York. It’s not a bordering state, but for anyone living in Northern Delaware, NYC is a casual Saturday trip. You hop on an Amtrak at the Wilmington station and you’re in Penn Station in 90 minutes. It’s often faster to get to Manhattan from Wilmington than it is from parts of Long Island.
What Most People Get Wrong About the Region
The biggest misconception? That these states are all the same.
They aren't.
Delaware is the tax-free haven. Pennsylvania is the industrial, rolling-hill powerhouse. Maryland is the "Chesapeake" state with a serious obsession with blue crabs and Old Bay. New Jersey is the garden-state-meets-commuter-hub.
People also assume the "Mason-Dixon Line" is just the border between the North and South. Technically, that line is the border between Pennsylvania and Maryland (and Delaware). It’s why Delaware is often called a "border state"—it has the charm of the South but the pace of the North.
The Commuter Reality
If you live in this cluster, your life is a jurisdictional nightmare.
- Taxes: You might work in Philadelphia (PA), live in Wilmington (DE), and do your weekend drinking in Jersey.
- Driving: You’ll hit three different toll systems in 40 miles.
- Sports: You’re almost certainly a Philadelphia Eagles fan, regardless of which state's dirt you're standing on.
Why the Proximity Matters for Travelers
If you’re visiting Delaware, you’re basically visiting the entire Mid-Atlantic. You can base yourself in a hotel in Newark or Wilmington and see three states in one day without breaking a sweat.
The Brandywine Loop: Start at the Hagley Museum in Delaware, drive ten minutes to Longwood Gardens in Pennsylvania, and finish with dinner in Kennett Square (the Mushroom Capital of the World).
The Beach Hop: Start at Cape Henlopen State Park. Drive south through Rehoboth, Dewey, and Bethany. Cross the bridge into Maryland and hit Ocean City. If you’re feeling spicy, keep going south to the Virginia Eastern Shore.
The History Run: Visit the Old State House in Dover, then head north to Philadelphia to see Independence Hall. It’s less than an hour away. You’re literally retracing the steps of the Founding Fathers, who probably complained about the humidity just as much as we do today.
Actionable Next Steps for Your Trip
Don't just stick to the main highways. The best stuff is found where the borders blur.
- Check your GPS settings: If you’re driving between Delaware and New Jersey, your GPS might try to take you over the Delaware Memorial Bridge. Check the ferry schedule first. It’s pricier, but you might see dolphins, and it’s way better for your mental health.
- Download a Toll App: E-ZPass is king here. If you don't have one, the "pay-by-plate" invoices will haunt your mailbox for months.
- Mind the Sales Tax: Do your big-ticket shopping (electronics, clothes, jewelry) while you are physically within Delaware’s borders. The 0% sales tax is real, and it’s the main reason the Christiana Mall is always a madhouse.
- Explore the "Delmarva" identity: Don't just think of these as separate states. The Delmarva Peninsula (Delaware, Maryland, Virginia) is its own cultural bubble. Visit the small towns like Easton, MD, or Berlin, MD, to see how the regional lifestyle differs from the big cities like Philly or Baltimore.
The Mid-Atlantic is a jigsaw puzzle where the pieces don't quite fit perfectly, and that’s the beauty of it. Whether you're chasing the "Twelve-Mile Circle" or just looking for a tax-free laptop, the states close to Delaware offer a variety you won't find anywhere else in the country.
