Bauer Rock has decent bouldering, but it’s covered in layers of graffiti. You can escape the worst of the graffiti by wandering downhill a bit. The history of bouldering hasn’t been well documented here, but you can find a few dozen boulder problems ranging from V0 through V7.
EPAC has established a relationship with Lehigh County Parks and Recreation. We look forward to working with them for some much needed clean up!
