This is a great look from the harbor side of Portland. You get to see the houses of the families that live on the ocean, multiple light houses, and a good look at all the islands. We even saw a couple of porpoises too! The tour guide was great! If you’re looking, do this one!!

Fun boat ride around to see all the islands and lighthouses. It was very chilly and windy out in the bay! Dress accordingly

Excellent Harbor Tour! Awesome tour guide. We learned so much about the Casco Bay, history, the islands, the wildlife and life in the area. This is a very user-friendly boat with access for children and older adults. Everyone was made to feel very welcome and comfortable. Wonderful experience!
