Herr Park Disc Golf - This course is flat for the most part with some trees and the like. Very well-maintained. About 15 minutes from Columbia. Let Google Maps or your GPS take you the back way (avoid 30 and 462). Very beautiful countryside.
Kline's Run Disc Golf - A very hilly and angular course with stunning views of the Susquehanna River. A challenging course for beginners. On the York County side of the river.
There are other disc courses around but these three are closest to Columbia.
