To drive through Acadia National Park on the 27 mile Park Loop Road, we recommend allowing yourself a minimum of about 3 hours. Depending on how much you want to stop and look around, that time may vary. Add a little extra time if you want to treat yourself to tea and popovers at the Jordan Pond House (the only restaurant located within Acadia National Park).
The guided tours (Oli’s Trolley and Acadia National Park Tours) through the park generally last about 2 ½ to 3 hours, and they let you out at 3 different stops, including Thunder Hole, Cadillac Mountain, and the Wild Gardens of Acadia.
