Well, if you're around Hershey Park in the summer the weather is definitely pleasant and warm. The
Hershey Park winters aren't bad but it is a bit chillier. Though, if you love the fall leaves with the great colors of change with reds, yellows, then fall is your best bet.
As far as attractions nearby, there's always ZOOAMERICA. It's just about as old as the
Philadelphia Zoo. If you're a history lover, then I would suggest making your way down to the
Liberty Bell,
Franklin Institute, and
Independence Hall. Hershey Park is in the city of Philadelphia and has many attractions to look forward to.
