Which Should You Visit?
Both Castine and Sag Harbor offer refined coastal escapes, but they inhabit different worlds entirely. Castine, perched on Maine's Penobscot Bay, operates as a serious maritime village where the Maine Maritime Academy shapes daily rhythms and Revolutionary War sites anchor conversations. The town closes early, locals outnumber visitors, and lobster boats share harbor space with naval training vessels. Sag Harbor presents the Hamptons' most accessible face—a whaling port turned weekend retreat where Manhattan professionals browse antiques between yacht club lunches. The shopping runs deeper, restaurants stay open later, and the harbor fills with pleasure craft rather than working boats. Your choice hinges on whether you want Maine's unvarnished maritime culture or Long Island's polished version of seaside leisure.
