Bailey Island, Maine
Home of the world's only cribstone bridge
Overview
Bailey Island sits at the end of Route 24, the final destination in a chain of islands connected by bridges through the sprawling town of Harpswell. To reach it, you must cross the Cribstone Bridge, a structure so unique it’s the only one of its kind in the world, built from 10,000 tons of granite stacked without a drop of cement.
The bridge was completed in 1928, ending generations of ferry service and connecting Bailey Island to Orr’s Island and, ultimately, the mainland. The design solved a particular problem: the fierce tides of Casco Bay would batter any conventional bridge. So engineers stacked granite slabs in a lattice pattern, leaving gaps for water to flow through while relying on sheer weight to keep everything in place. The bridge was designated a Historic Civil Engineering Landmark in 1984 and remains on the National Register of Historic Places.
The island itself is a working fishing village, one of the increasingly rare Maine communities where lobstering remains central to daily life rather than existing merely as tourist backdrop. Lobster boats motor out each morning, traps are hauled and reset, and the catch makes its way to pounds and restaurants that serve some of the freshest seafood on the coast.
Giant’s Stairs draws visitors to the island’s eastern shore, where erosion has carved the rock into dramatic step-like formations. Captain William Henry Sinnett, a lifelong Bailey Island resident, donated this 2.5-acre preserve to the town in 1910, ensuring public access to some of Maine’s most spectacular coastal scenery. The trail passes Thunder Hole, where waves compress into a narrow channel, and Pinnacle Rock, with views across Casco Bay to the open Atlantic.
The fishing families who have worked Bailey Island’s waters for generations are increasingly rare in a Maine where coastal property values have pushed many working waterfronts toward gentrification. Here, the balance persists, summer people and year-round fishermen coexist in a relationship that has evolved over decades but never broken. The lobstermen need the restaurants that serve tourists; the tourists come because the boats are real.
Mackerel Cove, on the island’s western shore, provides the protected anchorage that makes fishing viable. The cove fills with lobster boats, their colorful buoys stacked on deck between hauls. Visitors who time their arrival for late afternoon can watch the fleet return, a daily rhythm that has continued unbroken for more than a century despite wars, depressions, and the transformation of the Maine coast around it.
The island’s back roads. What few there are, wind past shingled cottages, artists’ studios, and the occasional grand summer “cottage” that dates to the Gilded Age. The architecture spans eras, from humble fishing shacks to Victorian showpieces, all compressed onto a rocky island where land has always been precious and views have always been spectacular.
Bailey Island represents coastal Maine at its most authentic: a community shaped by the sea, connected by a bridge that had to be invented because nothing else would work, and still home to families who have worked these waters for generations. In an era when so much of the Maine coast has been polished for tourism, Bailey Island remains genuinely itself. A working island that happens to be beautiful rather than a beautiful island pretending to work.

Frequently Asked Questions
What makes the Cribstone Bridge unique?
The bridge is built from granite blocks stacked in a crisscross lattice pattern without any cement or mortar. The weight of 10,000 tons of granite holds it in place, while the gaps between stones allow tides to flow through. It's the only bridge of this construction in the world.
Is Giant's Stairs difficult to walk?
The trail involves walking on uneven rocky surfaces and can be slippery when wet. It's suitable for most visitors but requires careful footing. The dramatic views make the effort worthwhile.
Can I buy lobster directly from fishermen?
While some fishermen sell from the dock, the easiest way to enjoy local lobster is at the island's restaurants, which source directly from the boats you see in the harbor.
