Cool Things to Do in Delaware: A Comprehensive Guide

Delaware is a tiny state with a lot of cool things to do packed in a small area. I-95 runs through the northern tip of Delaware, but Route 1 runs north to south through Delaware’s three counties. Here are our favorite activities in all three counties, heading generally from north to south.

Cool things to do in New Castle County, Delaware

State Parks in Wilmington

There are many lovely state parks in New Castle County. Purchase Delaware State Park passes here or at the park. They cost about $4 for an in-state vehicle and $8 out-of-state (with the exception of the seashore parks, which are a couple dollars more).

Alapocas Run State Park is one of the only places in Delaware where you will find blue granite cliffs that rock-climbers have long enjoyed scaling. Our children often enjoy the Can-Do playground and little story-book trail, as well as several nice woodsy trails.

Brandywine Creek State Park is a picturesque park of rolling meadows and forested area, and of course the creek. Chipmunks can be spotted near the blue gneiss stone walls (built in the late 1800s and early 1900s to mark property lines), and there are more than 14 miles of trail throughout the park, a disk golf course and plenty of fishing.

Bellevue State Park, a former DuPont estate, lies a few miles away. William DuPont’s home, Bellevue Hall, stands in the middle of the park. Find lovely horses throughout the park, along with stables, indoor horse training facilities, and a 1 ⅛ mile long horse track. There is a fishing pond, disk golf course, and several playgrounds.

Fox Point State Park includes a flat walking trail, pavilions, playground, restrooms and a view of the Delaware River. Watch ships from around the world on the river side and trains speed down the tracks on the opposite side.

Other State Parks

Auburn Valley State Park runs along the Red Clay Creek. It houses the world’s largest operating collection of Stanley Steamer cars, which offer rides on “Steamin’ Days.” A historic paper mill lies undisturbed in the middle of the park. The paved Oversee Farm Trail will get your heart rate up with its steep hill.

White Clay Creek State Park encompasses a very large area that runs into Pennsylvania. This provides ample opportunity to get lost if you’re not careful! (Yes, we know from experience.) You can hike to the Mason Dixon line or find the point where Delaware, Pennsylvania and Maryland come together.

Nearby Lums Pond State Park has Delaware’s largest freshwater pond, 17 miles of trails, a boathouse, camping, pavilions, a dog park, and a nature center with a few live animal exhibits. Our personal favorite activity is the Go-Ape Treetop Ropes course. This provides a great workout and some awesome zipline rides across the pond.

Other Local Parks

There are several parks in the city of Wilmington, including Brandywine Park near the downtown area. It is beautiful in late March/early April when the cherry trees bloom. In late May and June, the Jasper Crane Rose Garden is brilliantly in bloom. Formal gardens stand near the creek.

Brandywine Springs Park is a small county park that is on the site of an old natural springs spa resort (in the 1800’s) and later an amusement park (through the early 1900’s). Photographs along the trails showing what used to be built there make the park interesting.

Access Rockford Park through a pleasant drive through some of the most wealthy, historical, and beautiful neighborhoods near Wilmington. Notable for its huge tower, the park allows visitors to climb to the top during certain limited hours. Check this website for hours.

Ashland Nature Center is a fun place to visit in late July/early August, if you’re into hummingbirds. There is a hummingbird garden where you are sure to see fledgling hummingbirds feeding and honestly, I can’t get enough of them. They’re small enough to be insects and just so cute. There are also some small trails and educational programs for kids that includes examining little creatures netted from the creek.

Some other beautiful, free county parks include Glasgow Park (with numerous, modern playgrounds) and Carousel Park (with lovely playgrounds, horses, and even a little “Western town” area where the stables are located). The Newark Reservoir has an accessible playground, and a walking path up a steep hill that leads to the reservoir. It’s a great place to catch a sunset.

Old New Castle and the Wilmington Riverfront

The historic town of Old New Castle, Delaware, is just a few miles away from Wilmington. It was established in 1651 and was the landing place of William Penn. There are tons of Colonial and Dutch historical buildings, most of which are current homes and businesses. Jessop’s Tavern is one such building that is fun to visit.

People dress up and celebrate Dutch, Swedish, and English colonial history on Old New Castle Day, held on the third Saturday in May. The First State National Historical Park includes the New Castle Courthouse Museum, the Old Sheriff’s House, and the Green (which runs along the river and has picnic spots and playgrounds.) It is free, though parking may be metered.

There is a 5.5 mile mostly-paved trail that connects Old New Castle to the Wilmington Riverfront. The waterfront includes numerous restaurants and hotels, as well as a paved nature walk with a high overlook and boardwalk. This is also where the Delaware Children’s Museum is located. It is one of the best in the region, and you can easily spend several hours inside.

The Brandywine Zoo in downtown Wilmington is small, but the space offers a good home for the animals. It is perfect for young children who may not yet have the stamina to enjoy all there is to see at a larger (and pricier) zoo.

Not far away you will find the Wilmington Western Railroad, which offers a fun local train ride. Here you can meet the Easter Bunny in the spring, and Santa in December.

DuPont Estates, Museums, and Properties

Winterthur Museum, Garden and Library in the Brandywine Valley offers various tours, exhibitions, and interactive programs for children and adults. Our favorite annual events are the fairy days that are held in May, and the Halloween days in October, when our kids dress up and enjoy the children’s garden and enchanted woods.

This area is home to the Bidens, and is beautiful to drive through, with rolling forested hills and beautiful homes. Close by the area are Longwood Gardens (in PA), the Delaware Art Museum, and the Delaware Museum of Nature and Science (look upwards to see the giant squid there!)

Nemours Estate is another DuPont property with ornate lawns, gardens, and estate. Golden statues, marble pools, immaculate pavilions and fields of heavy blooms are brilliant in spring through autumn. You will find friendly and knowledgeable docents to show you how the ultra-wealthy lived during the gilded age. Children 5 and under are free. The estate is closed Mondays.

Mt. Cuba Center is a former du Pont estate featuring formal and naturalistic gardens featuring woodlands, ponds and meadows. You can find a lot of information here about native plants. It’s a lovely place for a long walk outside. Children 5 and under are free. The Center is closed Mondays and Tuesdays.

Hagley Museum is located in a gorgeous area along the Brandywine, and there is quite a lot to do there. There is a museum with rotating exhibits, usually relating to the industrial age in America. You can tour the Dupont family home as well. The old powder yard displays the whole process of making the gunpowder that first earned the DuPont family their riches. You can even see/hear a demonstration of some gunpowder exploding! Children 5 and under are free.

Art, History, and Science

New Castle County has some wonderful choices for families to learn about local history, art and science.

Pea Patch Island/Fort Delaware is a fun ferry ride to this historic landmark, which served as a Union prison during the civil war. Apparently we had a cannon pointed at Jersey in case they got out of hand. No hard feelings, Jersey friends. Now they have historic tours, people dressed in 19th century garb blacksmithing, laundering things by hand, etc. And to top it all off, they show you how to set off a cannon (though they don’t actually set it off, of course.) It is also a good place to see birds including ospreys, herons in season, and bald eagles.

Other local museums and attractions worth visiting include the Delaware Children’s Theater, where you can see wonderful local shows, and The Delaware Museum of Nature and Science. Here you can view prehistoric eggs, bones, and sea life, along with wonderful dioramas of various ecosystems. Downtown Wilmington offers several interesting museums, such as the Delaware History Museum and Mitchell Center for African American Heritage and the Delaware Contemporary (the only contemporary art museum in DE.) It also has beautiful historic churches and a gorgeous old library, along with a beautiful theater – the Grand.

Cool Things to Do in Kent County, Delaware

Delaware’s central county sits between the more populous county of New Castle in the north, and Sussex county to the south, known for it’s lovely beaches. Whether you want to visit Kent County or you’re passing through on a trip down route 1, there are plenty of fun excursions in this part of the state. Here are a few of our favorites:

Bombay Hook National Wildlife Refuge and other Wildlife Viewing

Bombay Hook National Wildlife Refuge is a gorgeous reserve in the northern part of the county, near the city of Smyrna. It is a beautiful wetland renowned for it’s birds. There is a 12 mile wildlife drive that loops around the refuge, and five walking trails (two are paved), with three observation towers, which offer a great place to take photos and get a good view of the birds on the water, especially in spring and fall when they migrate, and during sunrise and sunset. There are thousands of snow geese, ducks and other waterfowl in the winter as well. The cost is $4 per vehicle, and there is a visitor center open during the week and weekends in the spring and fall.

In May to early June, you can see the annual spawning of the horseshoe crabs at Pickering Beach or Kitts Hummock, where tons of these helmet like creatures come up on shore to mate. But, come too late and there will be stinky dead crabs everywhere! These are nice quiet places to view the crabs but not good beaches for swimming. You have to go further south for those!

The Capital City of Dover, DE

The Dover Air Mobility Command Museum is one of the best in the country, and it is free. If you have an airplane lover in the family, they will enjoy viewing the many historic aircraft in the main exhibit gallery and outside as well. C-5A cargo compartment tours are available, living history reenactors are on site most Saturdays, and you can sometimes visit one of the air control towers and watch the planes traveling in and out of the base. The Museum is open to the public Wed through Sun, 9 to 4PM.

It’s also fun to visit the more historic area of Dover, where Victorian buildings surround the area known as the Green, where Legislative Hall and other historic buildings are located. You can tour Legislative Hall and several of the other buildings for free. Tours take place the first Saturday of the month in the morning.

Silver Lake Park is just a few minutes from the Green, and is a pleasant place to picnic or walk a small trail around the lake. There is a small dam and playground equipment. Eat lunch or dinner at McGlynn’s Pub for a beautiful view of the lake.

The Johnson Victrola Museum is a small and very specialized museum where you can find a well curated collection of Victrola’s. Other historical early sound recording equipment and Nipper the dog artifacts are displayed there as well. The docents are wonderful, and the museum is free (though donations are appreciated).

Just outside of Dover is a small natural area called St. Jones Reserve, which is actually an Estuarine Research Reserve, but is open to the public. It is a quiet place with lots of wildlife, including bald eagles. There is no cost to enjoy the grounds.

Killens Pond State Park

Aside from the Dover Green and its’ surrounding buildings, Killens Pond in Felton, DE is the only state park in Kent County, but it is a beautiful one. The pond itself is lovely reflecting the trees, especially in autumn, and is surrounded by about a two and a half mile trail that is quite flat. You can fish, rent a boat, or visit the fun and affordable waterpark in the summer. There’s also a really nice nature center that is open May to September from 10 to 4 on weekdays, and 10 to 6 on weekends. The cost to enter is $4 for in-state vehicles and $8 for out-of-state.

Cool Things to Do in Sussex County, Delaware

The southernmost county of Delaware, Sussex County, includes rural farmland and the beautiful and popular beaches that tourists enjoy every summer.

Inland Attractions

The town of Milford straddles Kent and Sussex County and is a fun stop along route one to take a walk along the Milford River walk, enjoy a bite to eat or take in some art. There’s also a Can-Do Playground located in Milford that is very nice where the kids can expend some energy.

Further South you will find the town of Millsboro, where you can find retail and restaurant options surrounded by farmland, and within a quick drive of the beaches. The Nanticoke Indian Museum is also located in Millsboro, and is a fine source of information if you are interested in the indigenous people who lived in Sussex county before Europeans arrived. It is small, affordable, and worth checking out. You’ll also find information here on the Powwow which occurs in Sussex county every year, typically in the fall. The gathering includes dance, song, family celebration, traditional spiritual elements, crafts and artwork, native foods, kids activities, and a car show. It’s one of the largest indigenous/native gatherings on the East Coast.

Trap Pond State Park is about the farthest north you can find a bald cypress swamp. It has a nice network of walking and biking trails, bike rentals, a nature center, restrooms and playgrounds. The pond itself is a popular spot for kayaking and boating.

Delaware Botanic Garden along Pepper Creek is a wonderful place for a walk, full of beautiful seasonal blooms, unique and fanciful nature sculptures, and wildlife (including a pair of nesting bald eagles whose nest can be seen from the path). Kids get in for free, and tours are offered for $10 a person if you have an interest in botany and native plants.

State Park Beaches

Cape Henlopen State Park is both beach and park, and includes about 6 miles of coastline at the mouth of the Delaware Bay. The park includes “The Point,” where the Bay meets the Atlantic Ocean. The Seaside Nature Center highlights the ecosystems including barrier dunes, coastal beaches, and maritime forests. Fort Miles was built in the park during World War II, and the towers can be viewed along the drive.

Delaware Seashore State Park takes up a long span of beach and bay (about 20 miles), and has lots of amenities including campgrounds, cottages, playgrounds, fishing, angling, hiking, and even a museum – the Indian River Life-Saving Station. We like to go to the beach at Towers Beach in the park, where you can visit one of the eleven towers that were used for observation and defense during World War II (the same series that can be viewed at Cape Henlopen).

There are also trails to walk including the Burton Island trail, which can be accessed by driving out to the Marina at the very end of the Indian River Outlet. It is especially pleasant when the weather begins to cool down (and bugs are not as plentiful). The trail is fairy short and very flat, made up of boardwalk and sand.  You will find lots of scrubby beach vegetation, tall pines, cactus, crabs and shore birds. 

Finally, Fenwick Island, the Southern-most beach in Delaware, has it’s own state park with about three miles of beaches. Here you can find bathhouses and a pleasant place to swim or walk along the beach and look for ghosts crabs, which are plentiful along the shore.

Beach Towns

Lewes Beach is a charming little town filled with boutiques and cafes. It has a classy but friendly feel, and the Bay is great for little ones who want to swim without a lot of surf. It is known for its tulip festival in spring, and for the Lewes-Cape May Ferry to Cape May, NJ.

Rehoboth is not as quiet, but has a fun, mile long boardwalk and lots to do. Many come for the tax-free shopping at the outlets, but the beach itself at Rehoboth is clean, lovely, and worth the crowds. There is a nice playground near Lake Gerard with street parking, and it is only a block or two to the sea.

The town of Dewey, is just down the street from the Towers Beaches. It’s a great place to stop and eat dinner at the Starboard (or one of its subsidiaries, like the Starboard Claw), or ride the trolley around town.

You’ll find Bethany Beach near Fenwick Island, and you’ll notice pretty pastel buildings as you drive through. You may want to stop at the Boathouse restaurant, one of the most well-known features in the town.

Finally, the town of Fenwick has a few points of interest, including a lighthouse and accompanying marker from 1751. The lighthouse is open limited hours, and you’ll want to check their website prior to visiting. The DiscoverSea Shipwreck Museum houses over 10,000 artifacts from shipwrecks in the region (and around the world.) It also has limited hours, but is co-located with a charming souvenir shop called Sea Shell City that has all kinds of pretty crafts and creations made from seashells.
