DO I HAVE TO PASS THROUGH THE FEE STATION IN ACADIA NATIONAL PARK?

No, you can travel a good section of the One Way section of the Park Loop Road without passing through the fee station.  You will have access to Sieur de Monts Spring area with its Nature Center and Wild Gardens, as well as a number of hiking trails that begin there.  You will also have access to scenic pull overs as well as the famous Precipice Trail.
To avoid the fee station, as you approach it along the One Way section of Park Loop Road, get into the left hand lane and look for a road on the left just before the fee station and turn onto it.    A four way intersection is just ahead, go left to head toward route 3 and Bar Harbor, turn right to head for the Great Head parking area and trail head, or go straight ahead to enter the Schooner Head Overlook parking area.  In the parking area is a narrow paved path which leads to high cliffs over looking the ocean, as soon as you reach the cliff, you are standing on the roof of Anemone Cave, also known as The Devil's Oven.  The cave was abandoned by the Park Service and can only be entered at low tide, and the floor of the cave is very slippery.
