Verdugo Mountains

The Verdugo Mountains, also known as the Verdugo Hills or simply The Verdugos, are a small, rugged mountain range of the Transverse Ranges system in Los Angeles County, California. Located just south of the western San Gabriel Mountains, the Verdugo Mountains region incorporates the cities of Burbank, Glendale, Pasadena, and La Cañada Flintridge; the unincorporated communities of Altadena and La Crescenta-Montrose; as well as the City of Los Angeles neighborhood of Sunland-Tujunga.

Surrounded entirely by urban development, the Verdugo Mountains represent an isolated wildlife island and are in large part under public ownership in the form of undeveloped parkland. The mountains are used primarily for recreation in the form of hiking and mountain biking, and as the site of communications installations on the highest peaks.
