Inn at Diamond Cove

"Why did this hotel catch your attention? What's the vibe?Located at Diamond Cove on Great Diamond Island, The Inn at Diamond Cove feels tucked away. Only reachable by boat, the brand-new property is spacious and completely surrounded by nature. Tell us all about the accommodations. Any tips on what to book?If you’re already going to go to the trouble of getting to an island, you might as well splash out for one of the bi-level luxury suites, with their high ceilings, hardwood floors, and full kitchens. Whatever you book, the beds will be outrageously comfortable, and glass-enclosed showers complement the granite-topped bathroom vanities. Is there a charge for Wi-Fi?Wi-Fi is free of charge. Drinking and dining—what are we looking at?There are few options here, which is good, because there aren't a ton elsewhere on the island. The lobby bar and cafe serves casual fare; Cabana Bar serves poolside cocktails. If you venture off the property, Diamond’s Edge next door serves all the pastas, steaks, and baked stuffed lobster one could ever want. And the service? The guest services team is professional and well-equipped. Anything stick out about the neighborhood?Great Diamond island—at least this part—is car free, so everyone gets around on golf carts. Any other hotel features worth noting?The property has tennis courts, an indoor basketball court, a heated pool, duckpin bowling, an outdoor fire pit, a yoga studio, babysitting services, dry cleaning and laundry, and nightly turndown. It's enough that you don't need to, nor will you want to, leave. Bottom line: Worth it? Why?This is an unforgettable resort experience that's only 30 minutes by boat from Portland." - Joe Ricchio

We took our elderly grandmother for an overnight stay this past weekend and had an amazing experience. She is in a wheelchair and everything was surprisingly accessible for her at the Inn as well as on the island. We booked an ADA room with plenty of space for her to use her wheelchair or walker. The room was spacious, clean, well appointed, stylish, and the balcony was serene, being right in the woods. This is such a special Inn, the grounds are gorgeous, the island is quintessential Maine, and everyone is just so nice and helpful. We booked during their special opening weekend rates that included complimentary dinner and breakfast, the food was another highlight. We had dinner on the porch at Diamond's Edge and they had a huge variety of offerings, their vegan dish of summer succotash was insanely delicious, others in our group had the filet and the fish and chips- all of us very satisfied. Staying here this past weekend created such a wonderful memory with us spending some amazing time all together. We loved everything about it and have already agreed to come back again. Also, with our grandmother in her wheelchair, your staff went above and beyond to accommodate her needs, bringing up the golf cart just for her because she couldn't step into the van, and just creating a fun experience for her versus feeling like she was a burden. Your staff at the Inn were fun, friendly, personable, and made for a pleasurable stay for us all- thank you to Kayla, Simon, and everyone else who was always available to help out. You made it easy for us to visit and just focus on having good, quality family time together- you handled all the details for us and we had an incredible time.

Everything here is top notch. The setting is not like any other place you’ve ever been. It is so unique. It’s like going back in time to a simpler, slower pace of life. The preservation of this former military fort is priceless. 3 nice restaurants on this small island just a 30 minute ferry ride to Maine’s largest city…Portland. We have stayed here before and it is always a pleasure. Treat yourself to this pleasurable experience!

What a wonderful experience and an outstanding staff! Everyone was very friendly and professional, also very service forward, the best hospitality staff I have ever met. We were looked after like we were royalty and we can’t wait to go back. The room was fantastic, we had a King suite, and it was beautiful. Very comfy bed, and every amenity you could need. The breakfast was superb, amazing quality and extremely tasty! The two dinners we had at the Diamonds Edge, one being filet mignon and the other was a buffet featuring beef tenderloin, salmon and chicken with amazing side dishes…all mouthwatering gourmet goodness!

Spent the weekend at the Inn. The entire weekend was delightful even with the “usual” Saturday rain here in Maine. Staff at the hotel are great, caring, informative, helpful, go out of their way to be accommodating! Slept like a log both nights on a firm mattress that was extremely comfortable. We enjoyed the museum which is small but very informative on the history of the island and Fort McKinley. Had dinner at the Diamond’s edge on Friday night and Saturday night at the Crown Jewel to have the opportunity to visit both local restaurants. Both have excellent food and caring waitstaff! I guarantee you will love visiting the Inn at Diamond Cove!

What a lovely place! We thoroughly enjoyed ourselves. Our room was very nice and comfortable. The hotel amenities were very fun - pool, fire pit, basketball court, game room with foosball, ping pong, and bowling. And just walking around the beautiful island was a pleasure.

We had an absolutely amazing stay at the Inn at Diamond Cove! From the moment we arrived, the staff went out of their way to make us feel welcome and taken care of. Everyone was incredibly attentive, kind, and always ready with a smile or a helpful suggestion.||What really stood out was how friendly and accommodating they were to my kids. They made them feel just as special as the adults, which made the whole experience that much more enjoyable for my family. The peaceful surroundings, beautifully maintained property, and top-notch service made it the perfect place to unwind. There is food on the island but you also bring food with you and amazing options in Portland with a quick ferry trip! ||Highly recommend for families looking for a relaxing and memorable escape!

If you’re looking for a truly unique and relaxing getaway, The Inn at Diamond Cove is it. Tucked away on the historic Great Diamond Island, the Inn feels like a secret retreat — yet it’s just a short ferry ride from Portland, Maine.||The atmosphere is peaceful, romantic, and steeped in history. The beautifully restored military buildings give the whole place a distinctive charm you won’t find anywhere else. Our room was spotless, spacious, and tastefully decorated, blending luxury with cozy coastal vibes.||The staff was incredibly friendly and attentive, from the front desk to housekeeping. You can tell they genuinely care about making guests feel welcome. ||The island itself is like stepping back in time. No cars (only golf carts!), lush walking trails, hidden beaches, and historic ruins to explore. We spent our days biking, swimming, and just soaking in the quiet beauty of it all. Dining at the Diamond’s Edge restaurant nearby was another highlight — fresh seafood, gorgeous waterfront views, and excellent service.||A few tips: Be sure to plan ferry schedules ahead of time, especially in the evening. Also, bring comfortable shoes — you’ll want to explore every inch of this picturesque island!||Overall: A perfect spot to disconnect, recharge, and experience Maine at its most magical. We can’t wait to come back.

My two teenagers and I went here for the night. The place was gorgeous. Rooms have tall ceiling and each are unique. Probably the best part of the experience was the staff. They were all helpful and friendly! Especially Fernando at the bar. We can’t to come back.
