Luxurious Waterfront Accommodations in Bar Harbor

Stay

Sit, Stay, & Play at the Harborside Hotel, Spa & Marina

Opal Paws

Harborside Hotel, Spa & Marina is a Bar Harbor dog-friendly hotel that welcomes well-mannered dogs (max two per room) for a non-refundable fee of $100 per night, per dog. Upon arrival, your pup will receive a complimentary gift bag with waste bags and dental stick treats, plus an Opal Paws dog mat and food and water bowls – yours to keep for a $30 fee. To ensure a safe and enjoyable stay, dogs must remain leashed in public areas, and housekeeping should only enter when dogs are leashed or crated. While dog-friendly rooms are available, location restrictions apply, including the pool, restaurants, and beach per city ordinance. Our team will gladly review all pet-friendly areas upon check-in.

For further information on our Paws policy please visit our the Dog policy section on our Policies & Guidelines page.
