Mulholland Highway starts in the City of Calabasas and twists through the Santa Monica Mountains for thirty miles to Leo Carrillo State Beach. East of Las Virgenes the highway is mostly gentle but packs a few ups-and-downs, and gets some car thru-traffic. Only parts have a shoulder. In Calabasas it turns into Mulholland Drive, which has a quieter pace, as it tuns to gravel after another 7 miles, so don't use it for thru-travel.
The fifty five-mile Mulholland Scenic Parkway and Corridor is one of the most famous thoroughfares in the country. Constructed in 1924, twenty four-mile Mulholland Drive in the City of Los Angeles was envisioned by the famous Water Bureau Chief and City Engineer, William D. Mulholland, as a scenic road that would transport city dwellers to the mountains and beaches.
The winding route starts west of the 101 Freeway in Hollywood, and offers panoramic city, mountain and ocean views. Eight miles of the Scenic Parkway from the 405 freeway west to Woodland Hills remain unpaved, and are subject to closure. The MRCA maintains seven scenic overlooks on Mulholland Scenic Parkway.
