Department Overview

Exploring the Crum Woods


The Crum Woods encompasses 220 acres of mostly forested land straddling the Crum Creek in Swarthmore, PA. Most of this land is adjacent to the developed portion of the Swarthmore College campus. The woods contain walking trails and provide recreational opportunities for the Swarthmore College community as well as visitors to the campus. In addition to recreational uses, the woods are an integral part of 35 courses in 12 academic departments.
