Maine Beauty

My now husband and I got married here 9/9/2023 and could not have asked for a better wedding experience. Colleen, the day-of coordinator through the venue, made sure everything went absolutely seamlessly. You will truly be in great hands. All staff that we encountered were so dedicated to making sure we felt like their #1 priority the entire weekend. From the minute we arrived on the island, we carried nothing and wanted for nothing!

Last but certainly not least, you cannot ask for a more beautiful Maine venue. As 2 Mainers ourselves, it was important to us that our venue showed off the outdoor beauty Maine has to offer. So many of our guests told us it was the most memorable and beautiful wedding venue they'd ever seen. I cannot recommend enough using Diamond's Edge Restaurant & Marina for your big day! We can't wait to return for dinner and weekend stays every year.

Quintessential Maine Wedding Experience

The Inn at Diamond Cove is truly a one-of-a-kind place to have a wedding. My wife and I toured many venues in the Portland area but fell in love immediately when we arrived at the wedding grounds on Diamond Island. The Island is perfectly quaint and on the quieter side. The outdoor venue has a beautiful view overlooking the water, showing off a quintessential Maine skyline. Colleen and Hannah were so incredibly helpful and very organized leading up to our big day.

As for the day-of, Colleen and Hannah have everything nailed down to a science so you can rest assured everything will go well in their hands. The ceremony site was beautiful. The tent, decorations, table settings, and lighting were also impeccably done. The catering staff nailed their queues and delivered some delicious steaks and fresh fish in a lobster sauce (yum!) without any delays.


Overall, we had a lovely time working with the folks at Diamond Cove and would happily recommend it to others.

Quintessential Maine Wedding

We had an amazing wedding experience and it would not have been possible without our amazing venue! The staff goes above and beyond as soon as you book with them, and our family is still raving about how kind and accommodating they were during our wedding weekend. It was so convenient to have our ceremony space and reception area next to each other, and our getting ready rooms just a short golf cart ride away. We hosted our rehearsal dinner with them, and the food was top notch for that and for our wedding reception. Having a built in day-of coordinator through the venue was so great, and kept everything running smoothly with vendor coordination and timeline. Not to mention, the backdrop for pictures cannot be beat with the ocean at your feet. I grew up coming to Great Diamond Island during the summers, and I have a whole new appreciation for it now. The island is absolutely magical. I highly recommend booking with them, you will not regret it.
We're all about trust. Our community relies on honest reviews to help you make those big decisions with ease.

We couldn't have asked for a better experience working with the friendly wedding coordinators and staff at Diamond's Edge Restaurant and Marina this summer. Leading up to wedding day, Rachel was extremely helpful with many logistical questions and on the day of, was just as amazing. The view is gorgeous and the transportation to the island was seamless. It was a wonderful experience to play on the island and we look forward to going back. We highly recommend a Great Diamond Island wedding!
