I've only ridden there once and it was a bit much for me. A buddy is trying to figure the place out, I went to the Valley Mountain Bikers website and the only thing I see is South Mountain (Emmaus) Wildlands Conservancy, which doesn't SEEM to be the same thing. I could be confused. I don't see anything else listed there or even on the MTBR.com trail reviews for PA that looks like what I'm thinking of. The one time I rode there we started at South Mountain Park, on Mountain Dr. I believe we crossed a road at one point and probably wound up on Lehigh U property. TIA!
