One of the oldest continuously settled towns in North America, Castine sits at the tip of a peninsula on Penobscot Bay — four centuries of French, British, Dutch, and American history wrapped in a compact, elm-shaded village that's entirely walkable from the Town Dock.
Castine is a tender port — ships anchor in the harbor and run shuttles to the Town Dock floating pier.
💡 Pro move: Currents around the dock can run strong — hold the rail when boarding tenders. Allow extra time on windy days.
All cruise ships tender into Castine's Town Dock; there is no dedicated cruise pier.
| Cruise Line | Typical Berth / Arrival | Dock or Tender |
|---|---|---|
| Most cruise lines | Town Dock, Castine Harbor📍 | Tendered |
| Small expedition ships | Town Dock short tie-up (≤2 hrs, 9 AM–5 PM)📍 | Docked |
Castine punches well above its size — history walks, sea kayaking, oyster tasting, and harbor cruises all depart within steps of the dock.
Fort George (1779) is the site of the Penobscot Expedition — America's worst naval defeat before Pearl Harbor. The five-acre earthwork remnants are a short walk uphill from the dock, and 100+ bronze historic markers connect the dots between French, British, Dutch, and American occupation.
