Diamond's Edge Restaurant & Marina

Welcome to Diamond’s Edge Restaurant & Marina

Experience Island Dining at Its Finest!

With a brief and scenic boat ride from downtown Portland you are transported from the hustle and bustle of Portland’s Old Port district through the sparkling waters of Casco Bay to peaceful Great Diamond Island. Diamond’s Edge Restaurant is situated just steps from the marina, overlooking Diamond Cove.

Formerly an artistic retreat community and later the historic site of Fort McKinley, Diamond’s Edge remains rich in charm and history. A favorite among locals and visitors alike, Diamond’s Edge Restaurant is the perfect spot for a relaxing lunch or dinner featuring local seafood, New England favorites and amazing views.
