Overlooking the Azusa River on top of Chapman Canyon. The ride up is a great work out. Your reward will be a fast downhill ride. I go over 30 mph downhill here. It's pretty fun. The fastest I've gone was over 50 mph on a hill on Genessee in San Diego going north towards La Jolla. I haven't found to many side trails here like in Angeles Crest. I used to go mountain biking there all the time afterschool in La Canada.
