Gorgeous cove, helpful dockhand (we had to turn around our 38' sailboat in a small area to hook up the electric). Lots of day transients for the exceptional restaurant. No shore heads or showers that we found, except the restaurant, otherwise would be 5 stars. Unfortunately we did not know the general store was closed on Mondays, as we were hoping for breakfast and coffee there. Be aware that you have to thread your way through multiple mooring balls to get to the docks. It's a ferry stop, fun to watch it come and go.

Had a fabulous(though pricey) meal at Diamond’s Edge. Just an incredible setting. Austin was our wonderful server(even though there wasn’t enough support staff to help him) Been here many times and will be back.

Hi Joel, we're sorry that your experience was not what you expected. It sounds like you were not informed of all the island has to offer. Guests staying at Diamond's Edge Marina have access to a fitness center, arcade, bowling alley, and the Inn at Diamond Cove where breakfast (and coffee) is served every morning from 7:00 to 11:00am. We also have a tennis/pickleball court, and rent kayaks and bikes to our guests. We would love to make it up to you, so please let us know if you decide to come back.

Great time the tuna was not good but the issue was resolved.

by William M. - Verified user on Aug 29, 2024
As always, this is one of the most pleasant marinas to pull into. They're always waiting for you to arrive and ready to help you dock. And it's such a beautiful location with great food and fun beaches! Update: A year later, another visit, and another great experience. The marina manager always makes the process so easy, and it is such a great location. Update 2.0: Another year, another great experience at Diamond's Edge.

Simon the dock person was excellent and the accommodations were great

Nice floating docks, subject to some waking when boats or ferries pass by. Staff very nice, restaurant ambiance very nice, food was so so. Next time we will try Crown Jewel or eat at the inn. Loved the history of Fort Mckinley and especially enjoyed the golf cart history tour by Ben; fabulous researcher and historian. Diamond cove inn looks like a fabulous place to stay and very historical!

We are thrilled to announce the opening of our brand-new market, Dockside Provisions! Located right at the Diamond Cove Ferry Dock, Dockside Provisions offers a selection of beverages, snacks, convenience items and local goods. Stop by and grab a drink for the ferry ride, or bring home a gift from one of our amazing local vendors. Located at the northern end of Great Diamond Island, our 43 slip deep-water marina can accommodate vessels up to 105 ft. Our marina is available for guests at Diamond's Edge Restaurant, the Crown Jewel, the Inn at Diamond Cove, and all overnight boaters.

Visit the island to explore and take in 193 acres of spectacular natural landscape that inspires outdoor recreation and relaxation. The island is home to Diamond Cove, a small residential community that was a former military base built during America's Gilded age, the luxurious Inn at Diamond Cove, the highly-rated Diamond’s Edge and Crown Jewel Restaurants, and the Fort McKinley Museum.

All slip reservations include complimentary water and Wi-Fi, and access to shower and bathroom facilities. Please hail us on VHF channel 09 as you enter the harbor and we'll happily guide you to your slip. All dockage reservations will be processed through Dockwa.
