The Shore Path is a nice walking path just along the shore that I used for my morning walk. The sign says it's a half mile but I started my walk from the door of the Bar Harbor Inn and joined the Shore Path at the Town Pier. Then at the end I turned and walked up to Wayman Lane and returned. That was almost 2 miles.
As you walk there is incredible scenery including Balance Rock. There was even an apple tree with ripe apples on it when we were there.
