Maine’s cobblestone beaches are magical places

BANGOR DAILY NEWS • August 3, 2026

In Maine, we’re lucky to have quite a few cobblestone beaches. Worldwide, they’re considered somewhat rare. These fantastical beaches, composed entirely of round stones, form as a result of glacial activity and big waves. The cobblestones are often made from durable rocks left behind by glaciers. They’ve been rounded by being continuously tossed about by waves, then trapped in a cove. I’ve found spectacular cobblestone beaches at Cutler Coast Public Reserved Land in Cutler, Boot Head Preserve in Lubec, Quoddy Head State Park in Lubec, Bog Brook Cove Preserve in Trescott, and Acadia National Park. It’s tempting to select a favorite rock to carry home, but I urge you to leave them where you find them.
