If you’re in Portland, go to at least one, if not some, of these islands. The ferry is convenient, inexpensive, comfortable, and the views are fantastic. You can get off at one of the little islands, hike, eat, go to the beach, or do nothing,

Were love in Portland, and if we want to feel like we're on a great vacation, w hop the ferry and go out to the islands. Walking, biking, dining, ice cream. In fact, our daughter's wedding was on Peaks Island, and was amazing.

The mail boat trips, twice daily in summers, are the longest. Ordinarily, barring any emergency, there is no need to disembark a ferry until the entire trip is done. Ferries have restrooms. They also have limited vending... More
