Branford's Thimble Islands: Boat Tours, Pirate Lore, and History

Branford's Thimble Islands Offer Boat Tours Through a Storied Granite Archipelago

Off the coast of Branford's Stony Creek village, roughly 100 small islands dot the western end of Long Island Sound in what locals and visitors have long called one of Connecticut's most distinctive destinations. The Thimble Islands — some barely larger than a granite outcropping, others occupied by Victorian homes and private estates — draw boaters, kayakers, and day-trippers each season for narrated cruises through a landscape shaped by glaciers, granite quarrying, and centuries of local lore.

Three boat tour operators depart from the Stony Creek Town Dock at 4 Indian Point Road: Sea Mist, The Islander, and Volsunga IV. Tours run approximately 40 to 45 minutes and pass the islands by water without landing, offering views of the private waterfront homes that occupy roughly 23 inhabited islands. Adult fares run $18 on Sea Mist and The Islander. Sea Mist operates weekends in May and September, daily except Tuesdays in June through August, and weekends only in October.

Pink Granite and a Quarrying Legacy

The islands are composed of distinctive pink Stony Creek granite, the same stone cut from the working quarry that still operates on the mainland. The glacier that retreated approximately 15,000 years ago flooded the valley connecting the hilltops, creating Long Island Sound and isolating the granite ridges as islands.

At the height of the quarrying industry around 1900, as many as 1,800 men worked the Stony Creek quarry. The pink granite was used in some of the most recognizable structures in the country: the pedestal of the Statue of Liberty, the Brooklyn Bridge, and Grand Central Terminal. The Stony Creek quarry remains one of the few in the region still operating after more than 160 years.

The Stony Creek–Thimble Islands Historic District was listed on the National Register of Historic Places in 1988, recognizing its 19th-century resort architecture and quarrying heritage.

Captain Kidd's Alleged Lair and Money Island

The most durable piece of local lore centers on Captain William Kidd, the Scottish privateer executed in London in 1701 on piracy charges. Local legend holds that Kidd used the islands as a base — specifically that High Island served as his lookout and that the cove between its two ends sheltered his sloop. Money Island, the most populated of the Thimble Islands at 32 houses, takes its name from the buried treasure Kidd is said to have left behind. Kidd's Island bears his name directly, as does Kidd's Harbor.

The legend was actively commercialized as early as 1846, when entrepreneur William Bryan built a hotel on Pot Island — which he renamed Kidd Island — to attract treasure hunters and summer visitors. No treasure has been found, and historians note most of Kidd's known assets were accounted for at the time of his capture.

Notable Residents and Institutions

Several islands carry notable historical and contemporary associations. Davis Island served as President William Howard Taft's summer retreat in the early 1900s, making it, for those seasons, an informal summer White House. General Tom Thumb — the entertainer Charles Stratton, a P.T. Barnum protégé — summered on the islands and is said to have carved his initials into rocks on Cut-in-Two Island.

Governor's Island, about 10 acres with 14 Victorian homes, was formerly home to Doonesbury cartoonist Garry Trudeau and broadcaster Jane Pauley. Horse Island, the largest at 17 acres, is owned by Yale University's Peabody Museum of Natural History and used as an ecological research laboratory.

Outer Island, part of the Stewart B. McKinney National Wildlife Refuge under U.S. Fish & Wildlife Service ownership since 1995, is the only Thimble Island open to unrestricted public access. It is accessible by kayak or charter and provides habitat for wading birds, shorebirds, and the federally endangered Roseate Tern. Southern Connecticut State University and Central Connecticut State University conduct research programs on the island.

Getting There

All three boat tour operators depart from Stony Creek's town dock. Sea Mist (thimbleislandcruise.com) boards at the top of the hour for departures at quarter past. The Islander uses a smaller 26-passenger vessel that can access tighter passages between islands. Kayak tours, including guided circuits with a landing on Outer Island, are available through Branford River Paddlesports at Stony Creek Marina.

Stony Creek village, about a 15-minute drive from downtown New Haven, retains a Victorian harbor character with a small public beach, the Stony Creek Legacy Theater, and the Stony Creek Museum, which documents the quarry's history and immigrant workforce.
