“An easy trail meandering by a canyon rim and through a Ponderosa Park. Great for novice runners.”— Chris Liverett
Trail is used by runners, hikers, bikers, and horses. All trails in this area are multi-directional, so stay alert and be prepared to yield.
Upper Rim Loop (#312) starts at the kiosk near gate #5. A brief "technical" section is at the very beginning and consists of two small rocky sections. From the trailhead scamper through the gate to the first intersection. The trail branches here, if you want to see the view from the rim sooner rather than later, turn left and go around the circuit clockwise. Staying left at the first intersection takes you on a clockwise loop along the rim of Martinez Canyon over occasional rocky outcroppings and short steep sections. The tread is a bit rocky in some spots and soft smooth pine duff covered singletrack in others. so if it is too lumpy for you right now power through to the smooth stuff that is just around the corner.
At mile 2.3 you'll encounter the intersection with Creek Trail (#311); stay to the right to return by skirting some open meadows and jaunts through pine forest on varying grades to the intersection of Newt Jack (#305). Stay right, continuing clockwise until you return to the trailhead.
The trail makes a fine loop through big widely spaced trees. The butterscotch aroma from the Ponderosa pine will carry you over fun singletrack. The occasional patches (copse) of oak add a bit of variety. Keep your eyes peeled for cows and their droppings as they are allowed to roam so don't let your dogs get too far ahead, just run faster to keep up!
