tide pooling
Tide Pooling is possible in Acadia because of Acadia's location which is along the coastline and the coastline in this area is rocky causing these tide pools to form. While you are observing the tide pools you will be able to see many interesting organism like starfish and urchins.
Boating
While you are at Acadia you can have a chance to see the aquatic side of the normal ecosystems we usually see. It is a nice way to watch aquatic wildlife without getting wet, but you can also swim in certain beaches if you are dying to swim.
