There's also Wissahickon, Philadelphia's stunning urban gem that features epic gorges and some of Pennsylvania's best forest trails. Interstate 95, which weaves past the Delaware, will eventually take you to Tyler Arboretum in Media, Pennsylvania, a little over 50 minutes away from Philadelphia. This peaceful, public garden is ideal for daytrippers looking for a true escape from city life. Tyler Arboretum spans a total of 650 acres and features 17 miles of trails, which offer views of marshlands, forest, and historic buildings. The grounds and main hall were all privately owned until the 1940s, when the property became public land.
