Turn right on the powerline road to go through an old gravel quarry. There is a maze of trails in this area. Park on the left hand shoulder of the highway. The road is a little steep at the beginning. The road ends where the canyon starts cutting down into black basalt and gets really rough.
Trails go north and south around the rocky promontories of Water Canyon.
From the end of the Water Canyon road. A narrow. winding. It is a charming little path with a real wilderness feeling. The dirt road goes 2 miles to the rim of White Rock I Canyon. The Rio Grande is a narrow ribbon 1000 feet below.
