SR 56 meets Carmel Valley Road and curves northward, passing Canyon Crest Academy before turning southeastward. The route passes over McGonigle Creek before intersecting Camino Del Sur, which serves the nearby Westview High School. Southeast of Camino Del Sur, SR 56 curves back east, passing under Carmel Mountain Road without an exit. The route encounters exits with Black Mountain Road and Rancho Peñasquitos Boulevard in Rancho Peñasquitos in a primarily residential area before meeting its terminus at a partial cloverleaf interchange with I-15. Past the bridge over I-15, the road continues as Ted Williams Parkway, ending at Twin Peaks Road in Poway.
