From Interstate 10 or the 210 freeway, exit on Azusa and head north 10 miles or so, paralleling the San Gabriel Dam on your right. Turn right on East Fork Road and continue 8 more miles to the East Fork Station, where the road dead ends. Note that if you go around a hairpin 180 degree turn on East Fork Road, you missed the road into the Sheep Mountain Wilderness. The trail head is short distance down an obvious service road.
