ABOUT THE BUSINESS
Historic Charm, Waterfront Views, and a Taste of Downeast Maine
Perched along the shores of Frenchman Bay in Sullivan Harbor, Acadia Bay Inn offers a peaceful coastal retreat with sweeping views of Cadillac Mountain, Bar Harbor, and Acadia National Park. This historic waterfront inn combines the character of a classic Maine summer cottage with the comforts of a welcoming boutique bed and breakfast.
Built in 1888, the inn has been welcoming summer visitors for generations. Its seven individually styled guest rooms feature private bathrooms and balconies, with many overlooking the water. Guests can settle into the spacious porch, take in the changing light across the bay, or wander down to the inn's private pebble beach.
Mornings begin with a freshly prepared breakfast featuring local and seasonal ingredients. Throughout the day, guests can enjoy coffee and tea, relax on the porch, or ask the innkeepers for recommendations on exploring the surrounding area. The atmosphere encourages visitors to slow down and experience the quieter side of coastal Maine.
Conveniently situated between Bar Harbor and the Schoodic Peninsula, Acadia Bay Inn makes a comfortable home base for discovering both sides of Acadia National Park. Whether the day's plans include hiking, exploring coastal villages, or simply watching the water from the porch, the inn offers a welcoming place to return to.
For travelers seeking historic character, personal hospitality, and memorable waterfront views, Acadia Bay Inn captures the enduring appeal of a Downeast Maine getaway.
