* Follow paved road from upper parking lot to Upper Winter Creek Trail.
* Trail rises gradually and then descends to Hoegees.  At trail intersection   stay to the right (straight ahead).  Don't go up to Mt. Wilson!
* Cross the creek and follow the Zion Trail to Mt. Zion.  This is all uphill.
* At the clearing, continue left on the Zion Trail to Sturdevant Camp.  Or add   a few yards and take the short hike to the right to the top of Mt. Zion and   then go back to clearing.
* Arrive at Sturtevant Camp, relax, and fill bottles! :o)
* Leave Sturtevant Camp via lower Gabrielino Trail.  Don't go up to Mt   Newcombs Pass!  
* At Roberts Camp you can either cross the wooden bridge and take the road up  to Chantry or follow the First Water Trail which will give you a little more  dirt and a couple more stream crossings before connecting with the road  farther up.  First Water is a little longer.
