From the 210 freeway, take the Sunland Blvd. exit and go east towards Tujunga. Sunland Blvd. soon becomes Foothill Blvd., continue about a mile to Oro-Vista Street (Jack in the Box on left corner). Turn left on Oro-Vista street and zero your odometer. The trailhead is 7.8 miles from here (Just past the Vogel Flats turnoff), park in the second turnout. Cross the street, next to the road marker that say's "4.50". The trail starts out small, but is well maintained. After about a 3/4 mile the trail meets up with the main Condor Peak trail, turn left.
The Main Condor Peak trailhead starts 2.2 miles further up Big-T road. If you start there it adds about 2 miles roundtrip to your hike.
