South 4th Street Park 300 Fairview St, Emmaus, PA18049 Despite its name, this park is not on South 4th Street. You reach it by taking 4th up South Mountain until it ends,…More turning left onto Fairview and following Fairview around a bend until it ends. The entrance to Shelter House, one of the borough's historic treasures, is next to the park. The park itself consists of two baseball fields with a soccer field between them. Like the field on Klines Lane, the most amazing thing about this park is that such level playing fields were carved into the slope of the mountain.
