The 5,286-acre Nockamixon State Park lies in the rolling hills of Bucks County, close enough to Philadelphia for a day trip but far enough for a vacation. Tohickon Creek, Three Mile Run and Haycock Run feed the 1,450-acre Lake Nockamixon, a rest stop for migrating waterfowl and a destination for boaters and anglers. The park has a swimming pool, and visitors can stay overnight in a cabin.
