I am not exactly new to so cal, but I haven't really ridden on the trails around here. I recently acquired a GF Piranha and would love to take it out on some trails. I've been reading a number of online guides and forums and it seems that many of the trails are currently closed. I've done a couple of hikes in the area where I've seen mountain bikes are puttering around but I also signs that said hikers only (fire roads).

I would like to find some good moderate trails (not so much of an expert) and also bring people completely new to mountain biking, does anyone have any suggestions on trails or current guides? I am looking in the Pasadena general area since that's where I live.

Thanks in advance!
