Enjoy all that Maine has to offer as you board a private boat for a cruise through Casco Bay to a private island where you'll enjoy a delicious 'downeast' lobster bake and a tour of a Civil War Fort. Departing from the waterfront, you'll have magnificent views of Portland and the surrounding islands as you cruise through Casco Bay to House Island. With records dating back to 1661, House Island was one of the first islands in the Bay area to be occupied. Originally built to defend Portland against the British, the fort was later used to defend the north against the south during the Civil War. During your walking tour of the fort, explore the 70 gun casements, subterranean vaults, archways, tunnels and circular stairways of this unique fort. After you have worked up an appetite touring the fort, you'll be treated to a feast comprised of an approximately 1 1/4-pound lobster, clam chowder, corn on the cob, cole slaw, potato chips and blueberry cake and a non-alcoholic beverage. For the non-lobster lover, it can be substituted with chicken. Note: The topography of the island is not suitable for guests on wheelchairs. Participants must be able to walk approximately 1/2 mile over uneven and cobblestone surfaces with approximately 15 to 20 steps. Boat does not have a ramp.
