John Heinz National Wildlife Refuge

I agree with another reviewer that this is the best kept secret in Philly. This is such a lovely place -- A great place to be surrounded by beautiful birds and beautiful nature. It

Great sanctuary amidst urban Philadelphia. Great place to hike

A great walking, running, cycling park . Chances are, you will see wildlife . Enjoy year round, but avoid after heavy rain for low lying sections of trail .

A slice of the wild by the Philly airport . Be on the lookout for the bald eagles!

Best kept secret within the city ????????????

Go for a hike but please keep your dog on a leash!

So cool! Solar power and Geo thermal heat!

Great place for walking/biking/birding. Take the doggies!

The marsh is home to the coastal leopard frog, an endangered species in Pennsylvania. Read more

Did you know that The Nature Conservancy helped to preserve this great birdwatching spot?

Great place for taking nature pics.

Great place for cat and carp fishing

Run the surprisingly wild 3-mile loop trail around the marsh , surrounded by big migratory birds!

A lot of trash, broken glass, dog shit, & even nasty used condoms... where do the tax dollars go & why isnt this preserve being maintained?! Im appauled.
