Briefly skirting the Haight-Ashbury and Cole Valley neighborhoods, the route ascends Parnassus Street and passes the University of California, San Francisco's main campus. Turning south onto 7th Avenue in the Inner Sunset, the route curves around Mount Sutro and the Laguna Honda Reservoir before turning east and climbing Twin Peaks. From Twin Peaks Boulevard, drivers are directed into the north peak's parking area and offered unobstructed views of the city below. The route then descends into Corona Heights—built to take full advantage of the views at this height. Winding its way down the hill, the route takes drivers past the Randall Museum before descending east along 14th Street into San Francisco's prominent gay neighborhood, The Castro. Now into the drive, the route turns southward along tree-lined Dolores Street, passing Mission San Francisco de Asís and Mission Dolores Park while splitting the Castro, Mission District, and Noe Valley en route to Cesar Chavez Street. At Cesar Chavez Street, the route continues east through Potrero Hill before abruptly directing drivers onto northbound I-280.
