Getting Started
From Interstate 210, take the Azusa Avenue (SR 39) exit and go north winding up San Gabriel Canyon about 12 miles to where the East Fork Bridge intersects SR 39. Turn right, go across the bridge, and continue straight. In about 5 miles, you will come to a point where the road starts to curve very sharply right and uphill. Right at this curve, you will see a road straight ahead of you. Continue straight onto this road and in less than a mile you will come to the large paved parking lot at the end of the road overlooking the East Fork of the San Gabriel River. Park here. The trailhead is at 2,030 feet elevation and you need to get to 8,007 feet.
You will need an Adventure Pass to park at the trailhead.
