89 Best Sights in Connecticut, USA

This 93-acre natural sanctuary is home to 13 gardens with more than 2,000 varieties of annuals, perennials, wildflowers, and trees. There's a greenhouse, marked ecology trails (dogs are welcome), a pretty pond, and a boardwalk through a red maple swamp. Brilliant, bold colors make the wildflower garden stunning in spring.

The library's collection of literary papers, early manuscripts, and rare books include a Gutenberg Bible and original Audubon bird prints; the exhibition spaces on the ground floor and mezzanine are open to the public. The building that houses them is an attraction in its own right: the walls are made of marble cut so thin that the light shines through, making the interior a breathtaking sight on sunny days. Introductory tours for individuals are offered on Saturday afternoons; group tours are Yale-led and require advance registration at the Yale Visitor Information Center

Built in 1842, Bulls Bridge is one of a handful of covered bridges in the state still open to traffic; it was added to the National Register of Historic Places in 1972. If you feel like a hike, there is an easy trail that leads to waterfalls and a small gorge.

In the 1890s, visitors from New York's Art Students League journeyed to the Cos Cob section of Greenwich to take classes taught by American Impressionist John Henry Twachtman at a boarding house for artists and writers run by Josephine and Constant Holley. Thus, the Cos Cob Art Colony was born and flourished until 1920. Today, the circa-1730 house is known as the Bush-Holley House, which displays a wonderful collection of 19th- and 20th-century art by Twachtman, along with rotating art, history, and cultural exhibitions. The collection also includes personal papers, photographs, and records that reflect the long history of Greenwich and its inhabitants, from farmers to Gilded Age barons, politicians, artists and writers, and shopkeepers.

Fanning out from the State Capitol building, this city park is the oldest publicly funded park in the United States. Conceived by Rev. Horace Bushnell in the early 1850s, the park was designed by Swiss-born landscape architect and botanist Jacob Weidenmann. Some 1,100 trees and shrubs (157 different varieties) were planted, creating an urban arboretum. Kids love the Bushnell Park Carousel (open weekends, June–August), with its 48 intricately hand-carved horses and booming Wurlitzer band organ, built in 1914 by the Artistic Carousel Company of Brooklyn, New York, and installed in the park in 1974. A welcome oasis of green in a busy city, the park has a pond and about 750 trees, including a first-generation offspring of the state's historic Charter Oak (the state tree) and four enormous state champion trees.

Built in 1782, this was home to four generations of Butlers and McCooks until it became a museum in 1971. Today, it houses Hartford's oldest intact collection of art and antiques, including Connecticut-crafted furnishings, family possessions, and Victorian-era toys that show the evolution of American tastes over nearly 200 years. The beautifully restored Victorian garden was originally designed by Jacob Weidenmann.   Open for guided tours by reservation at least 7 days in advance.

This quaint ferry route has operated on the Connecticut River since 1769—originally a barge pushed by long poles, later using steam power, and now an open, self-propelled vessel. The crossing aboard Selden III, which accommodates 8 or 9 cars and 49 passengers, takes just five minutes but saves 12 miles of driving compared to taking the bridge. The bonus on the ferry ride: a beautiful view of Gillette's Castle, which overlooks the river.

The indoor, walk-through South American rain forest alone justifies a visit to this zoo. It comes alive with dozens of species, some rare and endangered such as keel-billed toucans, broad-snouted caimans, and black-and-gold howler monkeys living in a lush environment of waterfalls, ponds, greenery, and bamboo. The zoo itself has 36 acres of exhibits featuring more than 300 animals: bison, tigers, leopards, timber wolves, sloths, a red panda, bald eagles---and proud peacocks that freely roam the property right along with you. There's also a colorful carousel and a New England farmyard.

Visitors are welcome to watch potters as they work, producing a variety of items that are fired in an on-site, 35-foot-long, wood-fired tube kiln. A selection of items—including seconds—are available for purchase in the workshop. A larger store, located farther north in West Cornwall (415 Sharon-Goshen Turnpike), offers the wood-fired pots along with complementary items made by local glassmakers, woodworkers, and metalsmiths.

This shop is filled with antiques discovered by the owners on their regular trips to Europe.

Dr. Frederick Shepard Dennis, the former owner of these 240 acres and a noted New York surgeon, lavishly entertained his guests—among them President William Howard Taft and several Connecticut governors—in the stone pavilion at the summit of the estate. From its 1,627-foot height, you have a panoramic view of Haystack Mountain and parts of New Hampshire to the north and, on a clear day, New Haven Harbor about 60 miles south. Picnic on the park's grounds or hike one of its many trails. Autumn foliage here is spectacular!

Chapman Falls, a 60-foot cascade, is the centerpiece of this 860-acre park, an idyllic spot for bird-watching, picnicking, trout fishing (you'll need a license), camping, hiking, or simply dipping your toes in a clear, cold stream. The campground is open from mid-April through Labor Day.

In this park in Rocky Hill, about 9 miles north of downtown Middletown (halfway to Hartford), see 500 tracks left by the dinosaurs that roamed the area some 200 million years ago. The tracks are preserved under a giant geodesic dome—1,500 more are buried for preservation—making this one of the largest dinosaur-track sites in North America. You can even make plaster casts of tracks on a special area of the property.   To make a plaster cast, BYO 1/4 c. cooking oil, 10 lb. of Plaster-of-Paris, cloth rags/paper towels, and a 5 gal. bucket!

Visitors young and old learn about science and technology through hands-on STEAM learning experiences and demonstrations that explore electricity, computers, sound, light, magnetism, and energy. Particular draws include the Hall of Space, where you can touch a real meteorite and Skylab artifacts, and Teddy Bear Triage, where little ones can apply first-aid treatments to their own stuffed animals. Don't miss the planetarium shows—some geared to young children and others to all age groups.

Bring a picnic to enjoy in adjacent Adventure Park.

Hardware-store buffs and vintage-tool aficionados will feel right at home at this museum. Artist and author Eric Sloane (1905–1985) was fascinated by Early American woodworking tools, and his collection showcases examples of American craftsmanship from the 17th to 19th centuries. The museum contains a re-creation of Sloane's last studio and also encompasses the ruins of a 19th-century iron furnace. Sloane's illustrated books and prints, which celebrate vanishing aspects of Americana, are available for sale here.

It was here (legend has it), on the Groton side of the Thames River, that the infamous traitor Benedict Arnold stood watching the important port of New London (a supply center for the Continental Army and friendly port for Connecticut privateers) burn in 1781 during the Revolutionary War. Whether Arnold actually stood there is open to question; but the American defenders of Ft. Griswold were massacred by Arnold's British troops during the Battle of Groton Heights—and New London did burn according to his orders. The 134-foot-high Groton Monument, which you can climb for a sweeping view of the river and New London, is a memorial to the fallen. The adjacent Monument House Museum has historic displays; the Ebenezer Avery House, on the grounds and recently restored, is where the wounded were sheltered in 1781.

Once the location of the U.S. Coast Guard Academy and later the U.S. Navy Underwater Sound Laboratory, the fort was originally built to defend New London Harbor from British attack. You'll now find a 19th-century stonework-and-masonry fort, an extensive visitor center focusing on military history, a top-rate fishing pier, a waterfront boardwalk with fantastic views, and a picnic area when you want to relax.

Owned and operated by the Mashantucket Pequot Tribal Nation on reservation lands near Ledyard, Foxwoods is the largest resort casino in North America. The enormous compound, which opened in 1992, draws 40,000-plus visitors daily to its seven casinos with more than 3,400 slot machines, 300 gaming tables, and a 3,600-seat bingo parlor. This 9-million-square-foot complex includes four luxury hotels, a 5,500-square-foot pool "sanctuary," two full-service spas, a retail concourse, numerous dining options, several theaters and other venues that attract national performers, a video arcade, extreme sports facilities, a bowling alley, children's activities, an 18-hole championship golf course, and—as counterpoint to all that action—marked trails through the surrounding woods.

At this site are the remnants of a Revolutionary War fort whose American defenders were massacred in 1781 by British troops under the command of the American traitor Benedict Arnold. The 134-foot-tall Groton Monument is a memorial to the fallen; you can climb it for a sweeping view of the shoreline. The adjacent Monument House Museum has historic displays.

Opened in 1943 as the National Audubon Society's first educational nature center, the sanctuaries and trails are the best location in the area for bird-watching. During the Fall Festival and Hawk Watch each September, you can spot large numbers of hawks and other migrating raptors. Other events include early morning bird walks, summer and winter bird counts, birding classes, and field trips. The center is filled with interactive exhibits, galleries, classrooms, a wildlife observation room, and a deck with sweeping views of wildlife activity. Outside are 7 miles of hiking trails passing through 285 acres of woodland, wetland, and meadow.

A founding member of the Connecticut Wine Trail, the state's oldest winery opened its doors in 1975. You can stop in for tastings with or without a snack—or bring your own picnic. Enjoy live music as you sip on Saturday evenings.

Abolitionist and author Harriet Beecher Stowe (1811–96) spent her final years at this 1871 Victorian Gothic cottage, now a popular stop on the Connecticut Freedom Trail. The center was built around the cottage in tribute to the author of the antislavery novel, Uncle Tom's Cabin. Stowe's personal writing table and effects are housed inside.

One of the most spectacular views in the state can be seen from the 34-foot high stone tower atop Haystack Mountain (1,716 feet). You can see the Berkshires in Connecticut and Massachusetts, as well as peaks in New York and the Green Mountains of Vermont. A winding road will get you halfway there; then hike the rugged, half-mile trail to the top.

Converted from a private home into a museum by its talented owner, turn-of-the-20th-century female architect (unusual at the time) Theodate Pope, the house has a superb collection of French Impressionist art displayed in situ, including Claude Monet's Grainstacks and Edouard Manet's The Guitar Player hanging in the drawing room. Poetry readings take place in the elaborate Beatrix Farrand–designed sunken garden every other week in summer.

This winery produces more than 13 different wines, from sparkling to dessert. Tastings are available, and a wine bar in the hayloft with views of the lake serves a fine cheese-and-pâté board.

This 35-acre vineyard overlooking Lake Waramaug produces more than 14 varieties of wine—from sparkling to dessert. A weathered red barn houses a gift shop and a tasting room, where knowledgeable staff explain the various wines and wine-making techniques. A wine bar in the Hayloft, with views of the lake, serves a fine cheese and pâté board. There's also a picnic area.

The park is marked by its tall pine trees near the Housatonic River and has terrific riverside campsites (seasonal). Fly-fishers consider this 2-mile stretch of the river among the best places in New England to test their skills catching trout and bass (license required).

This is a family-friendly park: no alcohol allowed.

Heading north from Kent toward Cornwall, you'll pass the entrance to 295-acre Kent Falls State Park, where you can walk across a covered bridge, hike a short way to one of the prettiest waterfalls in the state, and picnic in the green meadows at the base of the falls.

Opened in 1846, the country's oldest amusement park is known to locals simply as "The Lake." Today's attractions include a lakefront beach, a water park, and a clipper ship with a 300-gallon bucket of water that gives unsuspecting guests a good dousing. There are also some pretty hair-raising rides, such as the Sky Coaster, Wildcat (New England's oldest roller coaster), Boulder Dash ("World's #1 wooden coaster"), and Zoomerang.

The 95-acre parkland surrounding idyllic Lake Waramaug, one of Connecticut's largest and most picturesque natural lakes, is a great place for swimming, boating, fishing, and picnicking. The park has 76 campsites in wooded and open settings (with bathrooms and showers available) that are available from Memorial Day through Labor Day; canoes and kayaks can be rented on-site in summer, too.
