Great Diamond Rentals

Experience Life on a Coastal Maine Island...

Great Diamond Rentals provides historic lodging on the serene and unforgettable Diamond Cove. These unbelievable historic homes make up Fort McKinley on the secluded Great Diamond Island in Casco Bay, a historic destination across from exciting Portland. Explore the island on miles of walking trails through the island’s silent old growth forest, or lie out on the private beaches among tidal pools and sea glass. After touring the amazingly restored Fort McKinley, retreat to your “officer’s quarters,” featuring crackling fireplaces, original woodwork and wraparound porches.

Family

This historical locale is now a burgeoning - and very unique - family getaway. Each barracks now houses eight family homes, all complemented by a day spa, five private beaches, playground facilities and nature trails. Tours are available.

Historical

This place was once a military stronghold, the coastal headquarters for the defense of Portland Harbor during the Spanish-American War. Today you can see and enjoy the brick barracks and Queen Anne-style quarters that once housed over 1000 soldiers!

Island

Diamond Cove Island was a critical coastal defense, especially defending Portland’s harbor which was closer to Europe than any other East Coast port. Today, it's a living museum featuring the original buildings and hardware of the period.
