Cape Cod: New England’s Longest Atlantic Peninsula

Massachusetts owns the title. Cape Cod—a 65-mile (105 km) glacial moraine peninsula curling like a flexed arm into the Atlantic—is the longest cape in New England.

Why It’s Special

• Geology: Terminal moraine of Laurentide Ice Sheet (16–18 ka). Kettle ponds, sand spits, dunes.
• Cape Cod Canal (1914) – Makes it an island technically (bridges: Bourne, Sagamore).
• 15 towns from Bourne to Provincetown. Each distinct.
• Cape Cod National Seashore (1961) – 40 miles protected beach, dunes, marshes.
• Maritime heritage: Whaling (Provincetown), fishing (Chatham), Pilgrims’ first landing (1620, Provincetown Harbor).
• Summer economy: 4M+ visitors. Ferries to Martha’s Vineyard/Nantucket.

Runners-up: Cape Ann (MA, 15 mi), Cape Elizabeth (ME, 8 mi), Cape Neddick (ME), Point Judith (RI). None rival Cod’s length, culture, or identity.

Cape Cod isn’t just geography—it’s a state of mind.
