From the start point (waypoint ‘START’) in the carpark at Pickering Brook General Store, head westward to cross the branch of Canning Rd (at waypoint ‘01’) and follow the dirt track (which is along the route of the old railway to the Kalamunda Zigzag line) to cross the main Canning Rd (at ‘02’). After about 50m (at ‘03’) the old Kattamordo Heritage Trail foot-track crosses the track. Turn right onto the Trail and up the roadside embankment to cross Canning Rd again (at ‘04’) and enter the forest which is initially mainly sheoaks. You are now in the Korung National Park. Relocate the foot-track which may be initially a little difficult to follow as it often becomes hidden under the layer of dry sheoak ‘needles’. Head northward, gently uphill. Ignore a track that veers off to the left after about 300m (at ‘05’) near the crest of the hill and soon cross Valencia Rd (at ‘06’). Continue along the Trail and pass another track junction (at ‘07’) before descending to meet Francais Rd (at ‘08’). Turn right to head SE along the road for about 100m, passing a fruit packing shed and orchard on your left. Re-enter forest (at ‘09’) just past the orchard boundary and head generally NE (via ‘10’) along the foot-track through a very pleasant section of jarrah forest. When the track divides at ‘11’, take either the higher or lower track down the hillside. The two tracks merge again at ‘11-1’. At ‘12’ the track veers NW and then descends near ‘13’ to cross the dirt road extension of Weston Rd. Follow the track northward, descending into Piesse Gully, with the boundary fence of an orchard on your right. About 100m to the right in the orchard you will also see the old Fernie cottage which was the home of one of the soldier settler families in the 1920’s. The track soon joins a dirt road near the crossing of Piesse Brook (at ‘14’). Continue northward up the road for about 100m. Soon after Valento Rd merges from your right, locate (also on the right) and follow a mountain bike trail which enters the forest at ‘15’. (You now leave the original Kattamordo Trail which continued northward uphill on the dirt road, with farmland and orchards on the left and forest on the right.) The bike trail initially climbs gently ESE-ward for about 400m, then climbs more steeply and more northward as it zig-zags up the hillside (via ‘16’ and ‘17’) through another nice forest section of mixed jarrah-marri-banksia. After ‘17’ the trail soon flattens onto a rocky lateritic surface and heads mainly NE-ward, crossing an old forestry track at ‘18’. (The original Kattamordo Trail (and sign) lies about 50m NW where it follows a track bounding adjacent farmland.) Continue along the bike trail (via ‘19’), crossing another old forestry road at ‘20, and veering sharply left (NNW) at ‘21’ to soon meet (at ‘22’) another old forestry road (which is also the route of the Kattamordo Trail). Turn right to follow the forestry track (via ‘23’) and pass through a junction with two other old forestry roads (at ‘24’) and continue ahead on the original Kattamordo Trail which re-enters the forest from the junction as a foot-track. Cross Patterson Rd (‘26). Soon after, the Munda Biddi Mountain Bike Trail joins from the right. Continue NE on the Trail and soon cross Walnut Rd (‘27’; The Perth Observatory is located 350m to the SE at the end of Walnut Rd). You have now left the Korung National Park. The Munda Biddi Trail re-enters the forest (State Forest) from a small cleared area close to the corner of Walnut and Lockwood Rds, then heads NNE through the forest for almost 500m, running mainly close and parallel to Lockwood Rd (to ‘28’), then reaching Gungin Rd (‘29’). Cross Gunjin Rd (old dirt road) to follow another mountain bike trail (not the Munda Biddi Trail) which continues initially NNE and then curves back generally northward. The bike trail soon descends a little then crosses a minor forestry track (at ‘30’). About 1km after the Gunjin Rd crossing, the trail climbs quite steeply over a distance of 400m to emerge from the forest at the SE corner of the Mt Gunjin summit clearing (at about ‘31’). Cross the summit area (‘32’) – which was the site of the former fire lookout tower – then follow Gunjin Rd NW downhill and turn left onto the Kalamunda Circuit track (at ‘33’). Continue quite steeply downhill on the track, passing the Little Ovens Trail turnoff on the right (at ‘34’; where you may also need to skirt around a mountain bike-jump set up across the track), and meet the Munda Biddi Trail again at ‘35’ (The Trail follows a forestry track here). Turn left to follow the Trail southward for about 700m, to a track junction (at ‘36’) soon after crossing a gentle gully. Stay on the MB Trail by taking the left turn at the junction and head WSW-ward up the hill to regain Gunjin Rd at ‘37’ after less than 1km. Veer right to continue uphill on Gunjin Rd and still on the MB Trail (via ’38’). After less than 500m veer right off Gunjin Rd at ’39’ to stay on the MB Trail and re-cross Walnut Rd at ‘39-1’. The 750m section from ‘39’ to ‘40’ is a re-walking of about 750m of the Trail already walked en route to Mt Gunjin. At the fork in the tracks at ’40’ veer left (southward) to stay on the MB Trail (the other fork follows the Kattamordo Trail). Cross Lockwood Rd and continue southward to a corner at ‘41’ where the trail bends sharply left and climbs eastward to a ridge. At ‘42’ the trail descends southward then swings sharply left (eastward) at ‘43’. Leave the trail at this point to continue straight ahead, southward, on an old overgrown vehicle track to reach Walnut Rd at ‘44’. Veer right to follow the road southward to ‘45’. Then veer right onto another old vehicle track to head SW back through the forest down a gentle slope. Re-cross Patterson Rd at ‘46’ and follow the vehicle track across a gentle ridge (via ‘47’) before descending increasingly steeply down the hillside toward Piesse Brook valley to a T-junction at ‘48’, overlooking a small farming property (a former orchard). Take the left fork to descend steeply down the hillside to ‘49’. Turn right (WNW) onto Forrest Rd (sealed) and pass orchards on your left, then the old 1920’s home of the immigrant Pollese family (just after the first gentle bend in the road). Piesse Brook runs along the valley almost parallel to the road just 100m downslope to the left. At ‘50’, at the junction with the unsealed Valento Rd, continue on the sealed road which becomes Repatriation Rd where it curves to the WSW. The road crosses a bridge over Piesse Brook and passes the entry to the Santora Arabian Horse Stud on the left. Leave the road at ‘51’ to re-enter the forest (and the Korung National Park) on an old forestry track which climbs initially steeply uphill from the south side of the road. It then veers SE-ward along the hillside via ‘52’. At ‘53’ turn right (SW) to take the side-track uphill and across the crest of the ridge at ‘54’. Then follow the old forestry track SW-ward downhill to meet a W-E vehicle track near ‘55’. Now rejoin Repatriation Rd (sealed) at ‘56’ and follow it WSW (via ‘57’) across another small valley flanked by orchards and fruit packing sheds. Then turn right (WNW) into Pickering Brook Rd (at ’58’) at the junction to get back to the Start point (via ‘59’).
Car shuffle option: If you are in a group and have done the suggested car shuffle at the start of the walk (see under Access / Directions), you will have left a car at ’55’ and can now avoid the final 1.5km of road-walking to return to the start point. This reduces the walk length to 11.5km.
Shorter route without car shuffle: If you are unable to do the car shuffle but still prefer to avoid the road-walking, then you have the option at ’50’ of bypassing Repatriation Rd and following the unsealed Valento Rd NW along Valento Rd back to ’14’ to re-cross Piesse Gully and then retrace your steps of the outbound route for about 2km to return to the Start point. This latter option will reduce the total walk distance slightly by about 0.5km.
