The Sunset is a very large neighborhood that takes up roughly the entire southwest quarter of the city. It is bordered by Lincoln Way (and Golden Gate Park) to the north and Sloat Boulevard to the south. Its eastern border is vague and lies somewhere around Laguna Honda Way. Numbered avenues go north-south and alphabetical streets between Irving and Yorba go east-west. The N-Judah and L-Taraval Muni lines serve the northern and southern portions of the Sunset, respectively.
