A rare turnkey hospitality opportunity in the heart of Mount Desert Island's vibrant bed-and-breakfast market, minutes from Acadia National Park. Set on Clark Point Road, one of Southwest Harbor's most sought-after streets, this historic property has operated for decades as a beloved inn. Built in 1902 as the home of Captain and Mrs. O.L. Mills and thoughtfully renovated over the years, the shingle-style building blends turn-of-the-century craftsmanship with modern amenities. A classic wraparound porch welcomes guests, and the main level offers gracious gathering spaces -- a generous foyer, living and dining rooms anchored by fireplaces, and a bar area -- rich with character and detail. The main house has 6 guest bedrooms, each with its own full bath and private balcony/deck; 4 include additional sitting/living rooms with coffee bars. The 3rd-floor penthouse suite features a private roof deck, shaded gazebo seating, and a hot tub with sweeping harbor views. A separate one-bedroom bungalow offers a living room and kitchenette opening to its own private deck and patio. The grounds are a resort-style oasis: a heated in-ground pool with slate deck, large hot tub, and outdoor shower, plus a large pad already prepared for an accessory dwelling unit (ADU) -- room to add income or living space. The lower level impresses with exposed granite-block walls reminiscent of a European wine cellar, a full kitchen open to a living area, and a spa-style bath with jetted tub and separate shower. Property includes deeded access to the town parking lot and dock. Just a half-mile from the center of town -- Southwest Harbor's working waterfront, galleries, and restaurants -- and minutes from the trails of Acadia National Park. Turnkey, established, and ideally positioned in one of Maine's premier coastal destinations. Also listed as MLS# 1665992
