Upper Rim trail, number 312 on the USFS printed map at the trailhead at Gate 5, is indicated by the first trail marker near the kiosk. The only "technical" section of this trail is immediately after the trailhead - comprising two small rocky sections. Turning left at the first intersection will follow the loop clockwise along the rim of Martinez Cr. canyon over occasional rocky outcrops and short steep sections. At the junction with Creek (311), take a right to return through Pine forest on undulating grades to the junction with Newt Jack. A right, continuing clockwise, will return to the trailhead.
