“Hidden gem in Casco Bay”
*****
My partner Andrew and I were married at Diamond’s Edge Restaurant & Marina in September of 2023 on what was one of the best days of our lives. Planning for the event began roughly a year earlier when, after returning to Maine to raise a family, we sought a wedding venue that would highlight the treasured coastal natural beauty while still being close to Portland. We came to find out that Diamond’s Edge Restaurant was the diamond in the rough we sought.
Stepping off a classic Casco Bay Ferry onto the dock, you are immediately transported away from the hustle and bustle of everyday life into an iconic scene of Coastal Maine tranquility (and away from cell service!) No cars are allowed on the island, resulting in a truly relaxed island experience. History buffs also have the chance to explore historic Fort McKinley - a highlight we didn’t appreciate until after the fact. Whether your guests stay at the Inn at Diamond Cove, a vacation rental, or visit for the day, it will surely be an experience they won’t forget. The venue itself was remarkable on every front. The scene of a tent reflecting on the ice pond is stunning, only exceeded by the view our guests were treated to with the cove in the background during the ceremony The culinary experience was exceptional, and it was an absolute treat getting to choose from their diverse and rich options for appetizers, entrées, and drinks. But what sealed the deal was the amazing staff of the restaurant, marina, and inn. Their willingness to go the extra mile, find solutions, and focus on the details was so assuring, only exceeded by their commitment to Andrew & I savoring every moment on our wedding day. Thank you, Colleen, Erik, Trent, Crystal, and your whole team!“

"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 are so thankful to everyone that helped make our best day possible.”
*****
As a born and raised Mainer, I knew I wanted to get married by the ocean. After doing our research and touring multiple venues along the coast, we knew Diamond's Edge was the perfect choice for us. Set in Maine's beautiful Casco Bay, the venue allowed us to show our guests just how stunning our state can be. Most of our guests travelled in for the big day and it was fun having them get the authentic ferry experience! Along with the idyllic backdrop and facilities, Diamond's Edge provided unparalleled service. Colleen and Greg (and so many others!) went above and beyond for our wedding weekend. I cannot stress enough how helpful, kind, and understanding they were from the initial planning stage through seeing us off after the wedding. Before the weekend, I had my worries about transportation to the island (guests, vendors, decorations, etc.), set up and clean up; however, Colleen was exceptional and incredibly organized throughout the process. Their team runs like a well-oiled machine. Also, THE FOOD. We have gotten numerous comments about how delicious the appetizers and entrees were! Shout out to the mini lobster rolls, beef wellington bites, ahi tuna spoons, and the beef tenderloin. Everything we ate went beyond our expectations. In conclusion, Diamond's Edge is a fantastic venue. One that we will continue to visit for our anniversary every year. We are so thankful to everyone that helped make our best day possible.
