Compared to most rides in the region, this section of the AZT is relatively flat and contains no major climbs. What elevation change there is, is both gradual and non-technical, making it a perfect place to head for a relaxing spin, even if you don't plan to hit all 15 miles. The trail is entirely singletrack, weaving in and alongside the canyon walls, offering frequent views down to the river.

While not viewed on this ride, the eastern half of Walnut Canyon is home to "25 cliff dwelling rooms constructed by the Sinagua, a pre-Columbian cultural group that lived in Walnut Canyon from about 1100 to 1250 AD," this source notes. There are multiple trails to view the structures within the Walnut Canyon National Monument, but none are immediately accessible via the AZT or by bike.

If you're coming from the north, the trailhead for this run is located on Old Walnut Canyon Road, just a short drive from Interstate 40 and just as close to town. The large trailhead is primitive and has no water or restrooms, but the unpaved parking area is large enough for horse trailers and larger vehicles.
