Tour Details

Take this scenic Diamond Pass Run cruise tour of Maine's Inner Casco Bay, past lovely Victorian cottages on the shorelines of Little and Great Diamond Island, and Peaks Island. Catch a glimpse of island life as we travel to four different stops.

Little Diamond Island was known as "Little Hog Island" during Colonial times. It is part of the city of Portland, and as of the 2000 Census, the island had a year-round population of five. Great Diamond Island, another island in Casco Bay, has a year-round population of 77. The island is not easily accessible by motor vehicle, and has a limited network of roads. The primary modes of transportation are golf carts and bicycles. At low tide, Little Diamond Island connects to Great Diamond Island via a semi-submerged sandbar.

Like other Casco Bay islands, Long Island was originally inhabited by Native Americans until settlers arrived in the 1600s. Colonel Ezekiel Cushing purchased the island in 1732 and is credited with being the first westerner to settle and build a house on Long Island. During World War II, Long Island served as a fueling depot for the U.S. Navy. Supply stations and army buildings were constructed on the island, and many of these buildings still stand along the shore of the island. Once known as the Coney Island of Maine, and later an important WW II outpost, Peaks Island today is a neighborhood within the city of Portland. Home to artists, retirees, commuters of all sorts and a substantial summer population, Peaks Island boasts a small-town feel with unparalleled ocean views and access.

Reviewer: Nancy Dobbs
This was an interesting trip since people who live on the islands were on the boat carrying grocery bags and push carts full to the brim with their purchases on the city. We stopped at many island docks to let people on and off. The scenery was spectacular and we were very close to land all the time.

This tour was riding a ferry to various islands to pick up and drop off locals and visitors. It was enjoyable.

Very interesting to see how people choose to live in the summer in these beautiful cottages on these small islands.

A short walk from the cruise pier, we would recommend this mail boat trip, if you don't want to spend a lot of money or time on an excursion. The Casco Bay Ferry shuttled people and freight out to the outlying islands. The captain provided interesting commentary about the area history. Beautiful scenery, nice boat ride, easy to do.

Reviewer: Anthony & Mia Cipriano
The Diamond Pass Run was a scenic and relaxing excursion. The terminal was easy to find from the ship and a short walk. We thought it was unusual, however, that there was no "tour guide" narrating the trip. Still, a good value.
