The Outer Sunset district, including the corridor from 46th Avenue to Ocean Beach, is increasingly referred to as Beachtown due to the surf culture. Some definitions also include everything west of Sunset Boulevard from Lincoln Boulevard south to Vicente Street.
Everything east of 19th Avenue is thought of as the Inner Sunset. (19th Avenue is a six-lane thoroughfare that is designated as part of California State Route 1, as it connects the Golden Gate Bridge to San Mateo County and points south. Within the Inner Sunset is a sub-district called Sunset Heights.
Parkside
Parkside is to the south of the Sunset District, mainly south of Quintara Street between 19th Avenue and Sunset Boulevard. Abraham Lincoln High School is located on 24th Avenue, and the Parkside Library is located on Taraval Street at 23rd Avenue. Stern Grove borders the neighborhood to the south. The Parkside as a neighborhood started in July 1905 when a syndicate led by William Crocker announced they had quietly bought land from the estate of Adolph Sutro and others to create a new million-dollar development. The "park" of Parkside was not Golden Gate Park, but rather the stand of trees and plants around Laguna Puerca (now called Pine Lake, and often called "Mud Lake" or "Crawdad Lake" by old-timers) west of Sigmund Stern Grove.
