Stayed here for a week.. one of the best vacation in the states I have had. great place to relax and get away from it all. excellent hotel on all levels.. no cars just golf carts and bikes..you can only go on the island if you are staying at the hotel. you can hope on their own boat to head into Portland. Besides the hotel which is great.. what a better way to go out for dinner that to take a 1/2 boat ride into Portland have dinner then to catch another boat back to Diamond Island and take a 15min stroll back to the hotel..then sit by the outdoor fire pit and have a drink talking to the other guest there.. wish I could say this place is terrible so I won't have a problem booking another stay there..so go and enjoy.. I went in Sept. perfect time to go

We stayed one night at the inn and thoroughly enjoyed ourselves. The staff was amazing. Everyone was incredibly helpful and nice. We arrived just a few days before the inn was to close down for the season and it was like having the place to ourselves (on a Thursday night). The room was beautiful and well appointed. It was clear that a lot of planning and thought has gone into the experience one receives at this inn. We left planning the next time we would be able to return.

Fantastic, we spent the day on Cliff Island, the motherland with family who still reside there and lobster for a living. Taking a boat taxi to Diamond Cove at sunset was breathtaking. We enjoyed an amazing fresh dinner at the Inn's restaurant down by the water and enjoyed an evening stroll before retiring to the quiet that only an island can offer and very comfortable beds and accommodations. Just wonderful!

This inn is beautiful and well appointed. The down side is the time of year when we visited. They were closing the following week. There was no place to eat with the exception of the inn. They were out of a lot from the menu. There is no place to get snacks or beverages. Most of the island is not accessible for a wheelchair.

I absolutely loved everything about this place! The natural beauty of the island, The decor of the hotel and the rooms, which I can only describe as casual elegance, the helpful and friendly staff and the great food. So peaceful and relaxing! I also love the history of the island with all the World War Two buildings that remain and have been restored. For example, the actual inn building used to serve as the barracks for the soldiers. Can’t wait to go back! Highly recommend!!
