30% off—Stay on a car-free Maine island this summer
Escape to a secluded island retreat off the coast of Portland, Maine.
Why We Love This Deal
Set on a car-free island in Casco Bay, this historic retreat feels worlds away from the mainland. Guests arrive by ferry and settle into Inn at Diamond Cove.
Originally built as an Army fort in the late 1800s, the property now offers a relaxing New England getaway with modern amenities. Spend the day lounging by the outdoor pool, biking around the island or kayaking along the bay.
