The rooftop pool is only open until sunset and is only accessible to guest who are 18 or older. This is for guest safety and for liabilities. We so offer access to our sister property across the street which is for guest of all ages as well as the Bar Harbor Club Pool and Spa, also available to those of all ages. We monitor the rooftop pool by staff and security camera. We will only ask for ID if the child appears younger then 18.
