From the Marshall Lake Trailhead the trail heads mostly west across flat forest land. It passes through a gate, drops into a small canyon, crosses a road and climbs out the other side. The trail crosses FR 128B and then descends steeply into Lower Walnut Canyon. It passes the Sandy's Canyon Trail junction, turns to the right and goes up the canyon. The trail forks to the right and climbs steeply out of Walnut Canyon at Fisher Point. Once on top it passes the Fisher Point Trail junction and then crosses FR 301. The trail parallels Walnut Canyon and passes another trail junction. After two more junctions the trail descends down into a tributary of Walnut Canyon. It follows the canyon for a short ways and then climbs steeply out of it. From here the trail joins a two-track and then heads north up to FR 303, which is a trailhead. The trail stays north of the Walnut Canyon National Monument until it crosses the entrance road. It then turns to the north and works its way down to Interstate 40.
About 6.4 miles from the south end of this passage the AZT splits. This passage and passage 32 continue in a wide arch through many gentle miles of the stunning Arizona high country around Flagstaff. Passage 33 takes users into town. Know that shopping opportunities are available on both routes, the bypass route crosses highway 89 less than two miles east of a large mall and motels, and cab fares in town are quite reasonable.
