Pennypack Park follows Pennypack Creek through Northeast Philadelphia, giving this part of the city a long green corridor of woods, water, and trails. It is not a formal garden or monument, but it is one of the better places in the city for an easy dose of nature.
The park works best for walking, cycling, birding, or a relaxed break from the busier historic core. Expect a local, practical park rather than a polished tourist sight.
