I'm going to be in Phoenix for a few days and would like to get a ride in. I'm probably only going to be able to ride 1 day so where should I go? Looking for singletrack XC rides, not DH as I don't have much experience with it. Is it necessary to have a guide? I'm not exactly sure where I'm staying but my friend mentioned to ride south mountain. Since I'm staying with him I'm going to assume it's close so what are my options in that area?
