Casco Bay Lines Mailboat Run Register View Cart

Hop on the Mailboat Run!  The Mailboat Run is, hands down, no contest, the most unique and interesting way to cruise Casco Bay.  This true working boat carries passengers, mail and freight to Little Diamond, Great Diamond, Long, Cliff and Chebeague Islands. This excursion lasts 2.5 – 3.5 hours depending on the route and cargo volume.  Bring a hat, sunglasses and plenty of sunscreen and water.  Pack a lunch and snacks to enjoy on the cruise. When we return to the dock, you will have time to explore the stores, eateries and sights of the Old Port on your own.
