"Let's get this straight: This is more than a park. The 134-acre preserve is dedicated to preserving native plants. You'll discover 700 of Pennsylvania's 2,000 native plant species here. It's ok if you're not a botanist; its 4.5 miles of nature trails are enough to soothe the soul of any urbanite. Don't miss the stone bridge—beautiful whether it's framed by fall foliage or covered in a dusting of snow." - Nancy DePalma
