First constructed as barracks for Fort McKinley in the 1890s, the Inn at Diamond Cove is now a peaceful destination where guests can unwind on Maine’s Great Diamond Island or explore its surrounding waters. Open Memorial Day through Columbus Day, the inn rests on a car-free island, and visitors are transported by golf carts and bicycles.

Guest rooms feature free Wi-Fi, hardwood floors, granite-top bathroom vanities, plush bathrobes, microwaves, coffeemakers, and pillowtop mattresses; guests have the choice of one king or two queen beds, and most rooms have private balconies. 

Diamond’s Edge, the property’s waterfront restaurant, serves local seafood and New England favorites for breakfast, lunch and dinner; room service is also available. The inn’s grounds include private beaches and wooded walking paths as well as a recreational hall with an indoor basketball court, an exercise studio with guided yoga classes and an antique duckpin bowling lane. All guests can enjoy the lobby lounge’s double fireplace as well as the outdoor fire pit. The heated outdoor pool includes a whirlpool tub and cabana bar serving handcrafted cocktails and snacks.

Guests can reach the property by taking a water taxi, the Casco Bay Lines Ferry service or by private boat, which can be moored in the on-site marina.

The Inn was warm and inviting. A very quiet setting away from the ha-bub of life. The staff was attentive but not overly so: just right. A serene setting with lots of history.

They need to replace the old, rusted, broken down bikes. Eating is expensive on the island.

Seemed like they were still finding their way, some things were amazing and others were unusual, but overall a cool place to visit.

Our booking was scheduled for Sept. 23, 2018 . Ten days before that date I investigated the ferry and on island dining reservations. The ferry enters seasonal mode as of Sept 22 with departures only early in the morning and at 545 pm . Water taxis are a very expensive option had they only answered their phones. The hotel dining restaurant had long since closed for the season. A long planned vacation was blown out of the water because this was not mentioned in the Travelzoo propaganda as it most certainly should have. I had a long and very productive conversation with the hotel admin as this process evolved and they were very surprised Travelzoo did not represent them accuratly. They were the ones who offered full refund which I gratefully accepted. it was too late to make new plans and i am deeply disappointed with Travelzoo and the year they robbed us of our Maine destination. you realize i can barely comment on these catagories because we never were able to go.
