Foothills of the San Gabriel Valley

The Foothills of the San Gabriel Valley are the foothills and hills in the San Gabriel Valley of eastern Los Angeles County, California. They include the foothills of the San Gabriel Mountains, and independent low mountain ranges of hills, in the east Greater Los Angeles region. The landforms are part of the Transverse Ranges System of Southern California and Baja California.

The ranges are roughly parallel the San Andreas fault to the north over the San Gabriel Mountains' ridgeline. They are generally along the Interstate 210 freeway, giving it the name "Foothill Freeway". The Interstate 210 and State Route 210 freeway covers 86 miles, between Sylmar in the west, through the foothills and San Gabriel and Pomona Valleys, to Redlands in the east.

The foothills provide greenbelts and contain Open Space Preserves and Regional parks. The undeveloped hill areas are part of ’s Mediterranean climate California chaparral and woodlands ecoregion – with montane chaparral and woodlands and Oak savannas habitats.
