Thousand Oaks, CA → Huntington Beach, CA

Your journey from Thousand Oaks to Huntington Beach follows a straightforward route that descends from the rolling hills of Ventura County down toward the Orange County coastline. You'll begin by heading south on US-101, which carries you through the Santa Monica Mountains foothills, then merge onto CA-23 South toward Moorpark before connecting to CA-118 East.
