Exploring Portland’s Hidden Coastal Gems: The Private Island Fort Tour in Casco Bay
Imagine cruising across the calm waters of Casco Bay aboard a cozy boat named Elizabeth Grace, heading toward a private island that’s steeped in history. This two-hour tour ($99 per person) whisks you away to Fort Scammel, a stone fortress from the early 19th century, and offers a rare peek into Portland’s maritime past.
What makes this experience stand out? First, the exclusive access to Fort Scammel, which has been off-limits to the public for decades, transforming it into a truly unique adventure. Second, the knowledgeable guides, especially Captain Pete, who brings the fort’s stories to life with humor and a genuine passion for local history.

The Voyage Out: Setting the Scene
The cruise itself is a highlight. We loved the way the guides share insights about the bay’s history, ships, and local scenery, creating a lively, engaging atmosphere. The boat ride is smooth, with plenty of opportunities for photos of Portland’s skyline and the wide-open bay. Expect to see lighthouses, which make for iconic photo ops, and enjoy the fresh ocean air—a real antidote to city life.
Exploring Fort Scammel: A Hidden Treasure
Arriving at House Island, where Fort Scammel is located, feels like entering a secret world. The fort, built in the early 19th century, is a stone fortress with an intriguing mix of French influences and underground passages reminiscent of catacombs. The fact that this site was active in combat makes it all the more compelling.
Our guide, Pete, kept the history accessible and entertaining. We loved how he explained the architecture and masonry, pointing out details that most visitors would overlook. The underground passages are a real highlight, especially since they’re preserved ruins you can walk through—a rare chance to go behind the scenes of a historic military site.
Authentic Details That Make a Difference
According to reviews, the knowledgeable guides are a major selling point. Several visitors praised Pete and Simeon for their friendly, informative approach. One reviewer said, “Captain Pete is extremely knowledgeable not only about House Island/Fort Scammel but Portland itself,” and this combination of local insight and historical storytelling makes the visit especially engaging.
What You’ll See and Do on the Island
Once on the island, you can explore the architectural remains and underground tunnels at your own pace. The tour emphasizes the historical importance of the fort—its role in defending Portland’s harbor—and how it influenced the area’s development.
While some reviews mention the walk around the fort is manageable for most fitness levels, a few note that kids might find underground passages a bit lengthy—so if traveling with children, be prepared for some walking and underground exploration.
