The ride out was beautiful and the skipper and mate were extremely friendly and knowledgeable. When we got to the island we were created by our guide. He was super knowledgeable and answered our questions with ease! The tour was exceptional with such historical importance! If you don’t go on this trip, you are truly missing something special!

    Great tour

    Adam_C, Sep 2025
    Pete was extremely informative and fun. We learned a lot and the fort was impressive. Highly recommend

    Response from Host, Oct 2025

    So glad you had a great time exploring the fort with Pete! He’ll be thrilled to know you enjoyed the stories and history out on the island. It’s such a fascinating place — thanks for the recommendation and for joining us!

    Chandria_M, Aug 2025
    Highly recommend! We ended up with only a small group of 6 which made the tour experience all the more memorable! Captain Pete is extremely knowledgeable not only about House Island/Fort Scammel but Portland itself. Simeon was a great deck hand as well!

    Response from Host, Oct 2025

    We love hearing this — thank you! Small groups make for such a special trip, and Captain Pete and Simeon will be so glad to know you enjoyed the experience. Exploring House Island and Fort Scammel with that kind of crew and view really is something memorable.

    Best cruise excursion out of Portland!

    Sarah_S, Aug 2025
    Fantastic tour, amazing history, beautiful island, great boat, fun crew. Highly recommend!!!!!! Every part of this tour was A+.

    Response from Host, Aug 2025

    We’re so glad you came out with us! Cruising across Casco Bay, stepping onto the fort, and hearing the stories behind the island really does make for a one-of-a-kind adventure. Our team works hard to keep things lively and welcoming, and it’s wonderful to know the whole experience felt top-notch. Thanks for the glowing recommendation!

    Best boat trip! Don’t miss this!

    Thank you for the glowing review! Cruising through Casco Bay and exploring the fort is an experience we’re proud to share, and it’s wonderful to hear our crew and guide made the day both welcoming and informative. The history out there is remarkable, and we love bringing it to life for our guests. We’re thrilled you found it as special as we do.

    Awesome Tour

    Jay_B, Jul 2025
    Extremely informative tour of the fort! Learned lots of history. The boat crew on the way to the island shared lots of things about the bay and ships and boats we saw

    Response from Host, Oct 2025

    We’re so glad you enjoyed both parts of the trip — the cruise across the bay and the deep dive into the fort’s history. Our crew loves sharing stories about the harbor and all the vessels out there, and the guides on the island really bring its past to life. Thanks for joining us!

    Perfect combo of exploring, history, and boat ride

    Dawn_C, Oct 2024
    This tour was amazing. Our captain was very knowledgeable, and eager to share history about the island. We explored areas with amazing stories behind them, and enjoyed a smooth boat ride, with great views and tasty drinks. He even let me call my dad (retired disabled Marine/war history buff) on speaker phone to catch his stories. We saw seals, and a deer. I would absolutely recommend this trip!

    A history lesson with a view!

    Elizabeth_C, Oct 2024
    Booked this experience on our last day to get out on the water and was blow away by the experience. The tour of the island was amazing, and Pete was such an amazing historian. We learned so much, enjoyed the beautiful views, and had an amazing experience to tell others about.

    Outstanding Tour!

    Ed_C, Sep 2024
    The narrative on the ride out to the fort and then the expert, knowledgeable tour guide on the island. The fort is amazing! Well worth going, a real highlight of our trip!

    Learn something new!

    Katie_D, Sep 2024
    All three crew members were super knowledgable and friendly! Some personal stories of the actual people who worked on the island would have been cool. But if you are into military history about guns, gun powder, architecture, stone building then I would highly recommend. The views are perfection!

    Would definitely do this trip again!!

    Mary_B, Aug 2024
    We enjoyed the great story telling of our guide on the island. The staff and Captain of the boat were friendly, and the drinks were great.

    Awesome experience

    TracyReady, Aug 2024
    Loved it tour guide was fantastic. Would do it again. Beautiful scenary and very informative. 5 stars all day

    5/5!

    Brittany_B, Aug 2024
    Very cool experience! Would recommend. The walk around the fort was not too difficult, most fitness levels would do just fine. Tour guide and captain were great!

    Educational

    Zachary_D, Aug 2024
    Great scenery, very knowledgeable tour guides, and great beverage for the trip back to shore. Highly recommended, even for those who aren’t history nerds.

    The narrative is...

    kay_p, Aug 2024
    The narrative is involved. I liked it but I think kids would be bored until they get underground. Be prepared to do some walking.

    Response from Host, Aug 2024

    Thanks for joining us and leaving a review! Our knowledge of this private fort is vast...getting underground is definitely a highlight of the tour! Kids also have a scavenger hunt that starts the second they board the boat to add to the tour at the fort and keep them engaged and excited!

    Not to Miss Experience!!

    Jennifer_C, Jul 2024
    We enjoyed the narrated boat ride to the private island. The host on the island was a wonderful tour guide. We learned the history of the island and saw beautiful views. We were given a lantern when we entered the underground portion. This is a not to miss experience.

    I would not choose to do this one again

    Janice_B, Jul 2024
    Tour guide great. Description of experience misleading. Boat cruise was simply ride to the island and back. The Fort was the bulk of the tour. No microphones for the boat guides difficult to hear any info about the boat experience

    Response from Host, Jul 2024

    Thanks for leaving a review and we apologize if our description was misleading at all! Docking at Fort Scammel and touring the fort is meant to be the guts of the tour! We also have a Lighthouse Tour and a Sunset Tour. Both of these tours are solely boat tours versus a guided tour of Fort Scammel on private House Island. We'll make sure our listing reflects this!

    Historical fort tour

    Chris_R, Jul 2024
    Great 2 hour trip to a historical fort in the Casco Bay, the guide was very knowledgeable and friendly. Perfect for the whole family, and there were a number of families on this trip.

    Response from Host, Jul 2024

    Thanks for the great review Chris! We loved having you aboard and hope to see you on another SeaPortland tour!

    fascinating tour of the Fort and its history. Enjoyable cruise of the bay The views from the island back towards Portland were amazing We even got to see a couple of seals on the boat ride out to the island.

    Great tour of the island...

    Charley_L, Jul 2024
    Great tour of the island and fort Awesome if you love history. For me, I liked the experience and exploring the fort, could do with a more abridged history

    Fabulous time!

    Kimberly_L, Jul 2024
    The tour was amazing and the people that sailed the boat and the guide were awesome! We had a bit of a time finding the meeting spot as it was not well marked.

    Fun History

    David_K, Jul 2024
    Awesome experience. Something cool and different to do. You are able to dive in and see Portlands history firsthand!

    Fun and informative experience

    Maura_S, Jun 2024
    Boat crew was very informative and fun. Boat ride was nice and shady on a hot day . Drinks were good. The private island tour was so educational! I love history and they told us about hundreds of years of history . It was great . We didn't expect it to be such an enlightening experience . Fabulous!! I highly recommend!!

    Great for the history buffs!

    Cathy_J, Jun 2024
    The fort was really cool! My teen was a little bored when our guide was talking about the history of the fort but that's kids lol. I found it very interesting! Our included beverage was tasty too!

    A must do tour

    Gregg_W, Aug 2023
