Out & Back route (14 miles total with +2,700 ft elevation gain)

Starting at the first bathrooms on the day parking lot we run quietly through the sleeping camp ground until we reach the dirt fire road. One mile on this road we take a left onto Serrano Canyon trail which will take us up into Serrano Valley. From there we take a sharp left so we make our way to the Old Boney trail, onto the Chamberlain trail. We run up this single track trail until we reach the famous “Chamberlain Rock”. It’s a local tradition to walk through the split to be freed from all sins.
Parking is available in certain areas along the PCH, you might have to walk a little. Best parking is along the big sand dune west of the Sycamore Campground.
