Alfred I. du Pont’s 77-room estate is one of the state’s essential Gilded Age experiences, especially for its formal French-inspired gardens and remarkable preservation. Use it as a deliberately paced half-day, not a quick house tour, and combine it with Wilmington’s other du Pont sites.
2.5h Timed entryChoose the first daily entry slot, particularly when the gardens are in bloom.
Reserve a timed ticket online in advance, especially for spring, summer, and holiday dates.
Pairs with: Winterthur Museum, Garden & Library · Hagley Museum (Tourist attraction) · Delaware Art Museum
The mile-long boardwalk is the classic Delaware beach-town walk: ocean views, saltwater taffy, casual food, and old-school amusements in one compact stretch. Come for an early-morning stroll or evening atmosphere, then use it as the spine for a Rehoboth visit.
1.5h FreeWalk before 9am or after dinner in summer; midday weekends are packed.
Pairs with: Rehoboth Beach · Funland · Dogfish Head Milton Brewery
Winterthur is the strongest all-round du Pont-country visit: an exceptional American decorative-arts collection inside a vast country estate, with gardens that justify time outdoors. The guided house component and scale reward visitors who reserve a substantial half-day.
3.5h Timed entryBook an early house tour and explore the gardens afterward.
Book online ahead for house-tour availability and popular spring garden weekends.
Pairs with: Nemours Estate · Hagley Museum (Tourist attraction) · Delaware Art Museum
Set on the Brandywine’s DuPont powder-mill site, Hagley tells the industrial story that explains much of northern Delaware’s history and landscape. Its mix of working landscapes, mills, worker community, and mansion is best approached as a wandering outdoor-history day.
3h Timed entryArrive at opening for cooler walks and less crowded demonstrations.
Advance online tickets are wise for weekends and special demonstrations, though ordinary-day entry is usually manageable.
Pairs with: Nemours Estate · Winterthur Museum, Garden & Library · Wilmington & Western Railroad
Rehoboth is Delaware’s best-known resort beach, valued as much for its walkable town, restaurants, and summer energy as for the sand itself. Use the beach in tandem with the boardwalk, but consider a nearby state-park beach if you want more space and fewer buildings.
3h FreeFor beach space, arrive before 9am in summer or visit on a weekday.
Pairs with: Rehoboth Beach Boardwalk (Tourist attraction) · Funland · Dogfish Head Milton Brewery
Cape Henlopen is the state’s most complete coastal park: Atlantic beaches, dunes, trails, a WWII observation tower, and views around Delaware Bay. It offers the natural counterweight to Rehoboth’s resort energy and is an essential first-time coastal stop.
3.5h Walk upArrive early in summer for parking, or visit late afternoon for cooler cycling and beach walks.
Pairs with: Rehoboth Beach · Rehoboth Beach Boardwalk (Tourist attraction) · Delaware Seashore State Park
This multi-site national park connects Delaware’s role as the first state with colonial and early-American sites in New Castle, Dover, and Wilmington. Start at the New Castle Court House or a visitor contact point, then use it as a framework for exploring historic streets rather than expecting one enclosed park attraction.
2h FreeWeekday mornings are best for the most peaceful historic-town experience.
Pairs with: Historic New Castle · Air Mobility Command Museum · The Grand Opera House
This is Delaware’s standout aviation museum, with huge transport aircraft displayed in a way that works for both enthusiasts and families. Allow time for the outdoor planes as well as the hangars; it makes an easy stop near Dover rather than a full-day destination.
2h FreeGo near opening on a weekend for the quietest aircraft viewing.
Pairs with: First State National Historical Park · Bombay Hook National Wildlife Refuge
The museum is particularly worthwhile for its Pre-Raphaelite holdings and American illustration, including a major Howard Pyle collection. It is a manageable cultural stop rather than an all-day museum, and works well between Wilmington estate visits.
1.5h Walk upWeekday afternoons are generally quiet.
Pairs with: Nemours Estate · Winterthur Museum, Garden & Library · Hagley Museum (Tourist attraction)
This is Delaware’s broad, less built-up ocean-and-bay beach experience, centered around the Indian River Inlet and its dramatic bridge. Use it for a beach day, fishing, or a scenic stop while moving between Rehoboth and Bethany rather than expecting a boardwalk-town scene.
3h Walk upArrive before 10am on summer weekends, when parking can fill.
Pairs with: Bethany Beach · Fenwick Island State Park (Tourist attraction) · Cape Henlopen State Park
A narrow barrier-island park between the Atlantic and Little Assawoman Bay, Fenwick offers a notably more natural beach escape than nearby resort strips. It is best for swimming, surf, paddling, and a quieter south-Delaware shore day.
3h Walk upGet there early on summer weekends; the small parking supply fills quickly.
Pairs with: Bethany Beach · Delaware Seashore State Park · Discoversea Shipwreck Museum (Tourist attraction)
Bethany’s short boardwalk has a gentler, more family-oriented character than Rehoboth’s livelier promenade. It is worth a sunset walk, ice cream, and an easy beach-town evening, especially when based farther south on the coast.
1h FreeSunset is the best time; mornings are quietest in peak season.
Pairs with: Bethany Beach · Delaware Seashore State Park · Fenwick Island State Park (Tourist attraction)
Trap Pond protects one of the northernmost natural bald-cypress swamps in the country, a landscape many visitors do not expect in Delaware. Rent a boat or kayak to get the point; walking alone is less distinctive than being out among the cypress knees.
2.5h Walk upPaddle early in the morning, when water is calmer and wildlife is more active.
Pairs with: Hopkins Farm Creamery · Dogfish Head Milton Brewery · Bethany Beach
Bethany is a quieter, compact resort town with a broad beach and a distinctly low-key family feel. It is a better base than Rehoboth for travelers seeking beach time over nightlife, and its boardwalk is an easy evening add-on.
3h FreeWeekdays and early mornings offer the most relaxed beach experience in summer.
Pairs with: Bethany Beach Boardwalk · Delaware Seashore State Park · Fenwick Island State Park (Tourist attraction)
Dogfish Head is Delaware’s signature craft-beer stop, and the Milton brewery gives useful context to a brand many visitors already know. It is best for adults interested in brewing and tasting rather than merely collecting a souvenir; designate a driver and pair it with southern-coast sightseeing.
1.5h Book aheadWeekday afternoons are calmer than Saturday tasting-room hours.
Reserve brewery tours and special experiences in advance; the tasting room itself is usually easier to access.
Pairs with: Trap Pond State Park · Rehoboth Beach · Hopkins Farm Creamery
The cobbled streets, Georgian and Federal houses, riverfront green, and old courthouse make New Castle Delaware’s most atmospheric historic town. Come to walk rather than race through individual interiors, ideally using it with First State National Historical Park interpretation.
2h FreeVisit on a weekday morning, before day-trippers and special-event crowds arrive.
Pairs with: First State National Historical Park · Air Mobility Command Museum · The Grand Opera House
The refuge’s tidal marshes and impoundments make it Delaware’s premier wildlife stop, particularly for migratory shorebirds, waterfowl, and birding drives. Even non-birders will appreciate it as a quiet counterpoint to the coast; bring binoculars and plan around tide and light.
2h Walk upGo at dawn or in the last two hours before sunset; spring and fall migration are especially rewarding.
Pairs with: Air Mobility Command Museum · First State National Historical Park · Trap Pond State Park
This compact, traditional boardwalk amusement park is a Rehoboth institution rather than a destination requiring a whole day. It is most useful as a family-friendly evening add-on after the beach or boardwalk, with pay-as-you-go rides and arcade games.
1.5h Walk upGo shortly after opening or later in the evening to avoid the longest summer ride lines.
Pairs with: Rehoboth Beach Boardwalk (Tourist attraction) · Rehoboth Beach
This restored 1871 Wilmington theater matters most if its performance calendar offers something you want to see; the historic room adds more character than a standard concert venue. Treat it as an evening complement to the city’s museums and estates, not a standalone daytime sight.
2.5h Book aheadArrive 30 minutes before curtain for the building and an unhurried seat.
Buy performance tickets in advance for headline acts and holiday programs.
Pairs with: Delaware Art Museum · Hagley Museum (Tourist attraction)
This eccentric, owner-built museum of shipwreck artifacts, coins, weapons, and diving memorabilia is a rewarding short stop for maritime-history fans. It is far smaller than the state’s major museums, so fit it around a Fenwick or Bethany beach day rather than making a special long drive.
45m Walk upVisit on a weekday or early afternoon; the small galleries can feel crowded.
Pairs with: Fenwick Island State Park (Tourist attraction) · Bethany Beach · Bethany Beach Boardwalk
This heritage railway runs through the Red Clay Valley in vintage equipment, offering a particularly pleasant way to see northern Delaware’s wooded Brandywine-country scenery. It is most worthwhile when paired with a themed excursion or for families and rail enthusiasts; regular rides are a half-day commitment once travel is included.
2.5h Book aheadChoose an early departure and avoid peak fall-color weekends unless tickets are secured far ahead.
Reserve online for weekend and themed excursions; popular seasonal trains can sell out well ahead.
Pairs with: Hagley Museum (Tourist attraction) · Nemours Estate · Winterthur Museum, Garden & Library
This large water-park and family-entertainment complex is useful for travelers with children who need a break from beach weather or museum touring. It is not a defining Delaware sight, but it can anchor a fun half-day near Rehoboth.
4h Walk upBuy entry at opening on hot summer days, when slides and attractions develop long waits.
Pairs with: Rehoboth Beach · Rehoboth Beach Boardwalk (Tourist attraction) · Funland
A working dairy farm with notably good ice cream, Hopkins is a pleasant rural detour rather than a statewide essential. It works best as a relaxed food stop while driving the southern Delaware coast and countryside, especially with children.
45m Walk upWeekday afternoons are easiest; expect lines after dinner on warm summer evenings.
