2014 Overlooked Park
John Heinz National Wildlife Refuge at Tinicum
The 350-acre freshwater tidal marsh nestled next to, yes, the airport is the only place in the world where you might catch a glimpse of a bald eagle with the Philadelphia skyline in the background. (If you don’t, consider the frogs, deer, muskrats and phenomenal bird-watching consolation prizes.)
