Walking Purchase Park consists of more than 500 wooded acres off isolated Constitution Drive, south of the Lehigh River,  near a heavily populated area in the northeastern section of Salisbury Township. The park has undergone a transformation in recent years, with the township, conservation groups and local mountain bikers mounting a concerted effort to clean up the park and design and maintain trails. Bikers praise its more than 10 miles of challenging, well-designed and well-maintained trails. The park is also popular among hikers, trail runners and deer hunters.

Once informally known as Riverside Park, the township board of commissioners named the woods in 2004 after the notorious Walking Purchase of 1737, whose unscrupulous participants may have crossed at or near the park.  The park includes land given to Solomon Jennings, one of the three white men who participated in the Walking Purchase which cheated the Lenni Lenape Indians of land. Thomas Penn, son of Pennsylvania founder William Penn, insisted the Indians signed a treaty whereby the Penns could have as much land as could be gained by a man walking for a day and a half.  Instead of a one man, Penn hired three who ran much of the way.
