Casco Bay Boat Tour: Forts, Lighthouses & Seals from Portland
Select participants and date
The bow cuts a clean white wake across Casco Bay as gulls wheel overhead and the granite walls of Fort Gorges come into view—a squat, circular relic staring back at the mainland like an island-sized gear from another century. On a two-hour cruise from Fore Points Marina, the coastline of greater Portland unfolds in close-up: spark plug lighthouses, shear cliffs, and small rocky stages where seals haul out, sunning themselves into indolent poses while the boat’s hum keeps a respectful distance.

Adventure Tips
Dress in layers
Bring a windproof outer layer—the bay’s wind chills can make a sunny day feel much colder once you’re on open water.
Bring binoculars
A compact pair will help you spot seals on Half Way Rock and seabirds on Cushing Island from a distance.
Non-slip shoes
Wear footwear with good traction for boarding and moving safely on a wet deck.
Tide-dependent stops
If you want to disembark at Fort Gorges, message the operator ahead to confirm your tour aligns with the tide window.

History
Fort Gorges was constructed during the Civil War to guard Portland Harbor; lighthouses in the bay date to the 19th century and were vital for guiding shipping into one of New England’s busiest ports.
Conservation
Seabird nesting and seal haul-outs are sensitive—stay at a respectful distance, follow guide instructions, and avoid disturbing wildlife or leaving any trash.
