This is an advanced ride, due to steep climbs and lots (and lots and lots) of rocks.

Walker Ranch can be ridden as a loop (jury is still out on preferred direction but clockwise might have a slight lead) but many ride it as an out and back to skip the hike-a-bike section. This ride starts at the Meyers Gulch trailhead, which give you a warm up on the Josie Heath trail before hitting the main Walker Ranch area. You'll descend from the parking lot, cross Flagstaff road, then climb up to the Walker parking lot. From there you have a fun 1 mile descent to the creek, but keep in mind this is a heavily hiked area After the creek there's a big climb to the Crescent Meadows parking lot. Then another fun descent and little climb to the stairs. If you do decide to hike down the stairs, know that the biggest, steepest climb on the Walker Ranch loop lies ahead. If this doesn't sound fun, then point your bike in the other direction and retrace your steps.

Another option to add more miles without the hike a-bike-section is to to start from the Ethel Harrold trailhead.

Trail is generally in worse shape than it’s been the last few years due to heavy erosion from rain and runoff and could use some maintenance love, but still a great ride. It rides best about 12 hours after rain (granite sand doesn’t retain water or get muddy) and gets sandy and loose on hot days otherwise.
