You can continue on 395 until you get to main street in Hesperia. Go east then turn south on Sante Fe Ave. It turns into Summit valley Rd. Follow this road until it ends on at the 138. Take 138 west and go over the I15. Get on the I15 south (only about 1 mile) and get off on Cajon Hwy (old I15 route not much traffic and scenic). Follow Cajon until it ends at Kenwood Ave. Take Kenwood under the freeway until you get to Devore Rd. Take a right going downhill and cross the freeway again. Then get back on Cajon Blvd (south or left). Continue south Cajon ends at Mt Vernon but continue on Mt. Vernon. Follow Mt Vernon and you will cross under I10. Just after the freeway is the Santa Ana River Trail. Take this south. I recommend following this until you get to Van Buren. Get off and follow until you get to Magnolia. Take a right on Magnolia and follow until you get in Corona. Then get on 6th through Corona until just before you cross over Hwy 91 (freeway). Turn left at Paseo Grande tog et on the frontage road.
