Philadelphia is known for its historical layout, which dates back to its founding in the 17th century. William Penn, who designed the city, envisioned wide streets and a grid system that made it pedestrian-friendly even from its earliest days. This layout encouraged walking and contributed to Philadelphia’s reputation as a walkable city. Over time, urban planning has further emphasized walkability, with efforts to enhance sidewalks, create green spaces, and improve pedestrian infrastructure. Today, many parts of Philadelphia remain highly walkable, particularly in the Center City area and along the Schuylkill River Trail, where pedestrians can enjoy scenic routes and easy access to amenities.
