The informative Hulls Cove Visitor Center anchors the park's main Hulls Cove entrance, which is 3 miles northwest of Bar Harbor via ME 3. Buy your park pass and pick up maps and info. The 27-mile-long Park Loop Rd, which circumnavigates the eastern section of Mt Desert island, starts near here.
When the visitor center is closed (November to mid-April), head to the Bar Harbor Chamber of Commerce for information. The park moves its visitor operations there in the winter.
