Private Island Fort Tour in Portland Harbor

★ 4.9 (83 reviews) · By SeaPortland

Experience Portland Harbor like never before with our Private Island Fort Tour in Casco Bay. Hop aboard the Elizabeth Grace for a two-hour cruise that takes you past stunning lighthouses and scenic views, culminating in an exclusive visit to Fort Scammel on House Island. This historic site, built in the early 19th century, offers a rare glimpse into the coastal defenses that once protected the area.

Access to Fort Scammel has been limited for decades, but thanks to a special partnership with its owners, we now offer private tours of this fascinating fort. Walk through its stone architecture, explore underground passages, and see the preserved ruins that highlight its French influences. It’s a truly unique experience that combines history, adventure, and breathtaking scenery.

Whether you're a local or visiting Portland for the first time, this tour is a must-do. Plus, you'll cruise past some of Casco Bay’s most iconic sights, including lighthouse beacons that dot the coastline. Please note, the tour requires a minimum of four participants to operate, and groups of six or more can inquire about private charter options for an even more personalized experience.
