||Head towards Pecos from SF, when you come up to the Apache Canyon Sign EXIT! Take a left under the interstate and take your immediate left on to an adjacent road next to the highway. Take that for about 1 1/2 miles and you will come up to a road on your left. Turn there and take this road till you get to a small stream and a railroad crossing. Continue to head straight and up the road, you will eventually reach the top and the pavement ends, up on your left you will see a grouping of boulders, on top of one you will see what looks like a giant rattle snake. This is a rather a landmark to know you are begining to get towards the rock. About 100 yeards past Rattle Snake is a dirt parking lot on your right. Park there and proceed through the gate and up the trail.
