From this spot just off of the San Francisquito Creek Trail in Santa Clarita, CA, you get fantastic open views down the valley across the grasslands and of the powerlines. This is a nice place to stop and sip some water or snap a photo before continuing on your ride.

North of Los Angeles is a beautiful canyon. It runs from Newhall to Sand Canyon Road. This land was once occupied by Tataviam Native Americans. The canyon provides beautiful views of the western San Gabriel Mountains and it makes for a super good cycle section.
