Hersheypark has an official facility parking map that provides parking information for the entire Hershey Entertainment Complex which includes the park itself, ZooAmerica, Hersheypark Arena, Hersheypark Stadium, and Giant Center. Chocolate World is separate but adjacent to the complex, creating a bit of a divot in the shape of the perimeter of the complex.
Below are two maps the park has made. The second map was updated in 2017 due to the realignment of Park Boulevard which occurred in late 2016.
Map 1: circa 2003-2016
Map 2: 2017-present
