Loved by guests
"It is a fully renovated property with homes that can be rented also."
"Hotel guests are able to access many special parts of the island including an old building housing a little bowling alley ( duckpin)."
"The Inn itself is gorgeous on a lovely quiet island for some exploring."
Island Accommodations
The Inn at Diamond Cove offers condominium-style rooms with balconies, hardwood floors, and pillow-topped mattresses. Options include king rooms, double queen configurations, and multi-level suites with full kitchens featuring Bosch induction cooktops and Miele dishwashers. Some units include fireplaces and separate living areas with queen sleep sofas. All bathrooms have granite vanities and glass-enclosed showers.
Dining & Bars
Diamond's Edge Restaurant serves local seafood and New England dishes overlooking Casco Bay. The Lobby Bar Café provides Starbucks coffee and grab-and-go breakfast options. The poolside Cabana Bar offers sandwiches, salads, and beverages. Dinner service runs from 5:00 PM to 9:00 PM daily, with waterfront dining available on the deck or lawn.
Recreation & Activities
Guests access a heated saltwater pool, tennis courts, duckpin bowling, and a 24-hour fitness center. The resort fee includes bicycle rentals, while kayaks and paddleboards are available for $50 per two-hour session. Activities include guided tours of Fort McKinley Museum, yoga classes, and basketball. The property features walking trails, secluded beaches, and an indoor game room.
Island Location & Access
Located on car-free Great Diamond Island in Casco Bay, the inn is accessible via Casco Bay Lines ferry from Portland's Maine State Pier or by private boat. The full-service marina accommodates boats with 30/50 amp electrical service and water access. Golf cart transport meets guests at the dock for transfer to the property. Self-parking is available at Portland's Municipal Parking Garage.
Guest Services
Services include luggage handling, golf cart transportation from the marina, and van-accessible parking. The resort fee covers high-speed Wi-Fi, bottled waters, and access to the fitness center and pool. The property offers accessible guest rooms with roll-in showers and visual alarms. Meeting spaces total 5,500 square feet, with partnership programs available for team-building activities on nearby Cow Island.
“The island setting immediately impresses: a car-free environment encourages exploration by bicycle, included as a perk. Lodgings in a former military fort offer a unique sense of place, while waterfront dining focuses on local seafood. I think the range of activities, from kayaking to historical discovery, makes this a standout destination for families and couples alike.”
