North on Pomerado Road to Highland Valley(just south of Lake Hodges). Right on Highland Valley for about 10 miles (good hill training), then right on Archie Moore. South on Archie Moore to Hwy 67 and south on 67 to Scripps Poway. Go down the hill (watch your speed) for a few miles until there is a break in the middle of the road. Carefully cross the road and descend what appears to be a driveway. There is a chain across the road so walk around it. Turn left and descent to Garden Hwy. Left to Poway Road and continue.
