My wife and I are going to Arrowhead for Labor Day weekend with group of friends. I'm contemplating riding from Pasadena to Arrowhead , well Cedar Glen to be exact. Is it legal to bike Highway 18? I have never seen anyone biking that road. I mapped a route going up the backside via Cajon, Silverwood Lake areal. This route is almost exactly 100 miles, which is a bit far considering the elevation change. One issue with this route, all surface roads seem to stop just short of Cajon Junction where I would begin climbing up to Arrowhead. Has anyone ridden in this area to know if there is a way through? Can one ride the 15 for this short section?
