Cadillac Mountain is the major destination of visitors to Acadia national Park. Accessible by car, it is the highest point on the east coast, and offers magnificent views of a glaciated coastal and island landscape. With intense visitation through the summer months for the past fifty years, the summit area has sustained substantial loss of soil and vegetation. Some rare plants are found at the summit.

Educational signs and visitor exclosures have been installed, and an occasional ranger presence established. The University of Maine conducted observational research of visitor behaviors in 2000 and 2002. Reports of theses studies are available in Acadia's Resource Management Bibliography. A census of visitor use was conducted for one day in August of 2001 and 2002.
