Penn-State Behrend DGC
One nine-hole disc golf course exists at Penn-State Behrend on the campus. Parking is limited during the school year (you may get a ticket), but during the summer, the course is relatively easy to access and use. You can find more information about this here: Penn-State Behrend DGC.
Edinboro University DGC
A second course at Edinboro University exists as well. The DGCR page for this course is here: Edinboro University DGC.
