We provide year-round ferry services, scenic cruises and boat tours from Portland to the islands of Casco Bay such as Peaks Island, Little Diamond Island, Great Diamond Island, Chebeague Island, Diamond Cove, Long Island and Bailey Island. We also offer scenic cruises, summer-time music cruises, private charters, and lobster bakes.

We Depart from Casco Bay Lines Ferry Terminal, corner of Commercial & Franklin Streets in downtown Portland.

Whether you're a tour director, a school teacher, or the father of the bride, Casco Bay Lines is the way for your group to go! For transportation to an island or a scenic cruise around the bay, you have a choice: you can go by our regularly scheduled service, or charter one of our boats for your own private ride.

Discounted group rates are available for groups of 20 or more on cruise tickets only. Please note that group rates are not available for round trip tickets to an island. Your group must be booked to qualify for group rates.

If you have a very large group (50 or more), a private charter may be more comfortable and cost effective for you. Please contact us and we will be happy to help you make the best choice.
