Sunland-Tujunga is a Los Angeles city neighborhood within the Crescenta Valley and Verdugo Mountains. Sunland and Tujunga began as separate settlements and today are linked through a single police station, branch library, neighborhood council, chamber of commerce, city council district, and high school. The merging of these communities under a hyphenated name goes back as far as 1928. Sunland-Tujunga contains the highest point of the city, Mount Lukens.

In the 1950s through the 1970s, the area was known as a "haven for asthma sufferers" and that it was "long noted for the beneficial qualities of its pure air" and had a "reputation as a health resort" or a "reputation for clean mountain air". Tujunga was seen as having a "near-Switzerland setting – high and dry".

Bolton Hall is one of few points of historical interest. It is a historic American Craftsman-era stone building in Tujunga. Built in 1913, it was originally used as a community center for the Utopian community of Los Terrenitos. From 1920 until 1957, it was used as an American Legion hall, the San Fernando Valley's second public library, Tujunga City Hall, and a jail. In 1957, the building was closed. For more than 20 years, Bolton Hall remained vacant and was the subject of debates over demolition and restoration. Since 1980, it has been operated by the Little Landers Historical Society as a local history museum containing artifacts, photographs, documents, the old clock from the first Tujunga Post Office, and memorabilia of Sunland-Tujunga and the foothill area.

McGroarty Arts Center is Historic Cultural Monument No. 63 of the City of Los Angeles. It was built in 1923 by John McGroarty, poet, Los Angeles Times columnist, and author who served two terms as a Democratic congressman from California. The building now offers instruction in art, music, and performance exhibitions, and hosts cultural events.

Angeles National Golf Club, at the base of the Angeles National Forest, the only Nicklaus-designed golf course in Los Angeles County, is an 18-hole, par-72 championship golf course.
