Took the small ferry to Peaks Island. Not much there to see or do. Rented a golf cart for $50 for an hour to drive around the island. To expensive and nothing much to see.

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

I have no specifics for Peaks Island, but in general, rental costs on the Casco Bay islands, like elsewhere, will vary with the season (high, low, shoulder).
