Start in Eastlake Chula Vista heading towards Tecate. Jump up to Sunrise highway and into Julian. Head down through Ramona and toward Escondido to hook up to Del Dios Highway. Ride down to the beach in Del Mar and finish off at San Diego Harley. (Or dealer/hangout of choice)
Long route out Otay Lakes then South through Campo, Up Sunrise HWY to Julian for a break, Down the 79 to Lyons Valley and back out Otay. Watch for hidden CBP and Mexican Semi Trucks while on the 94.
Nice ride up the technical side of Julian and down into lakeside trough wildcat canyon. Don't forget to stop for pie in Julian or even at the casino on the way down. Watch out for drivers crossing into your lane there is an average or 3 major motorcycle crashes a weekend up here.
