Delaware

Delaware sits on the Delmarva Peninsula along the mid-Atlantic coast, bordered by Maryland to the south and west, Pennsylvania to the north, and New Jersey across the Delaware River to the northeast. Despite being the second-smallest state in the nation, Delaware offers a surprisingly varied landscape, ranging from the rolling hills and hardwood forests of the Piedmont in the north to the Atlantic Coastal Plain that covers most of the state, while the Piedmont occupies only northern New Castle County.

The state’s eastern edge is defined by the Delaware Bay and a stretch of Atlantic Ocean coastline in the south, giving it both bay and ocean beach experiences. The Delaware Bay shoreline is internationally recognized for one of nature’s most dramatic wildlife spectacles: the annual spring gathering of horseshoe crabs and hundreds of thousands of migrating shorebirds. The coastal southern region, anchored by Rehoboth Beach, Bethany Beach, and Dewey Beach, draws millions of visitors each summer for swimming, watersports, and boardwalk culture.

Northern Delaware centers on the Brandywine Valley, a culturally rich corridor of gardens, historic estates, and museums rooted in the legacy of the du Pont family. This region connects seamlessly with southeastern Pennsylvania and offers some of the state’s best hiking at Brandywine Creek State Park. Dover, the state capital and hub of central Delaware, is home to The Dover Green, a site of First State National Historical Park, and the nearby Dover Air Force Base, which hosts periodic airshows and open houses such as the First State Airshow when scheduled.

Delaware’s 17 state parks encompass more than 20,000 acres and include coastal parks, forested preserves, and riverfront trails. The Delaware Bayshore Byway, a federally designated National Scenic Byway at 157 miles, traces the bay shore through tidal marshes, fishing villages, and wildlife refuges including Bombay Hook National Wildlife Refuge, a premier destination for waterfowl and wading birds.

The best times to visit Delaware for outdoor travel are late spring and early fall, when temperatures are mild, wildflower and fall foliage seasons peak, and the coastal crowds thin. Summer remains the top season for beach destinations along the Atlantic shore, while birders and nature lovers often target May for the extraordinary horseshoe crab migration along Delaware Bay.
