From the start point (at waypoint ‘START’), walk west to the nearby corner of Yarra and Qualen Roads at ‘1’, then south down Yarra Road for about 750m (to ‘2’). Then veer left to follow an old vehicle track uphill SE through open wandoo woodland for about 250m (to ‘2-1’). Continue due south along the hillside, initially through open woodland and soon through Parrot Bush shrubland (to ‘2-2’). Then veer SE again and enter open mixed forest (wandoo-jarrah-marri). Cross a stream course at ‘3’ and continue approx. SE to ‘3-1’ located on a broad flat ridge in very sparse, open jarrah forest and low heath (on a ‘pea gravel’ surface). Cross a vehicle track at ‘3-2’ and descend gently to ‘3-3’ into the head of a small side valley. Veer left to head ESE down the side valley and re-enter wandoo woodland. Reach a broader, gentle N-S valley and cross a stream course to ‘4’. Veer right (SE) and meet a minor vehicle track / trail bike track at ‘4-1’. Follow the track SE across a very gentle low ridge through jarrah forest. Veer left (eastward) at ‘5’ to leave the track and meet another track at ‘5-1’. Leave the track to descend eastward into a very gentle valley, again mainly through wandoo woodland. Cross a stream course at ‘5-2’ and climb the eastern flank of the valley to ‘5-3’, re-entering jarrah forest. Cross Korner Road at ‘5-4’ and continue ENE to near a broad flat hill top at ‘6’. Veer left (NE) to follow a very broad gentle ridge top upslope. Cross Sullivan Road at ‘6-1’ then veer left (NNE). Soon re-enter wandoo woodland along the edge of the laterite-capped hill top which drops away to the east. Continue NNE to descend the hillside. Cross a stream course at ‘7’, then veer NNW to cross a small low granite outcrop and walk gently uphill, initially through some sheoak shrubland and then back into wandoo woodland before re-crossing Korner Road at ‘7-1’. Continue WNW up a broad ridge (to ‘7-2’) in attractive woodland, including some large wandoo. Then veer northward along slope and soon descend to cross a gully to ‘7-3’. Then veer right to head initially NE-ward up a rocky slope, picking an easy route through a patch of tall heath and gaining a pleasant local view SSE across the small side valley. Soon reach a rocky ridge at ‘7-4’ and veer left (north), initially gently upslope before descending to a NE-sloping granite outcrop at ‘8’ with views eastward across the forest to wheatbelt farmland (which lies east of the Darkin River). Head NW and gently downslope from the outcrop into shrubland (to ‘9’). Then veer approx. westward downslope through wandoo woodland for about 150m to cross a small gully at ’10’). Then head northward to soon cross another small gully at ’10-1’. (Or see Option below for longer traverse of granite outcrop.) Continue northward up the sloping granite outcrop to ‘10-2’. Veer right (NNE) to pass through a sheoak thicket. Reach an open area at ’10-3′ and veer right (NE) to descend the open, partly rocky slope, with views again to the east. Continue NE down a forested hillside to reach a granite outcrop at 11′ which provides local views across the small side valley. Then turn sharp left to head NNW for only about 100m to cross the nearby rocky ridge and reach the edge of wandoo woodland at about ’12’. Then veer westward, to head steadily upslope for 600m across partly rocky ground and through low she-oak thickets. Reach open wandoo woodland again at the top of the ridge and (at ’12-1′) veer approx. NW (partly through a short section of scratchy heath) to reach a small rocky knoll at ’12-2′ from where there is a sweeping view NE. Then veer left upslope for less than 100m through heathland to get back to open woodland close to the summit area on the ridge (elevation 376m). Then head WNW to follow the ridge very gently downhill via ‘13-1’ and ‘13-2’ through open woodland, initially keeping slightly to the right (north) side of the ridge crest, clear of the fairly dense Parrot Bush thicket along the crest. Cross Qualen Road at ’13-3′. Continue WNW, descending gently to ‘14’, initially through mixed forest, then back into open wandoo woodland on a broad, flat valley floor . Veer right (NW) to head down the valley (via ’14-1′) and at ’14-2′ veer left (westward) to climb gently uphill avoiding the Parrot Bush thicket upslope on the left. At ’15’ veer left to head SW, initially upslope into woodland (via ’15-1′), then along slope on the NW-sloping hillside. Veer left (SSE) at ‘16’ to continue along the steeper slope. Cross a gully at ’16-1’ and reach a rocky ridge at ’16-2′, and pass by, or cross through, a group of large granite boulders. Descend a little along the SW flank to ‘17’, then turn sharp right (SW) to cross the head of another gully and then a narrow, Parrot Bush-covered ridge at ’17-1’. Continue SW downhill through shrubland and heath to soon reach Yarra Road (at ’18’). Turn left to follow the road southward. At ’18-1′ veer left (more southward) off the road to cross a small valley and return to the start point on Qualen Road.
Option for slightly longer walk (~17km): For a fuller traverse of the granite outcrops in the NE, instead of crossing the small gully at ‘10’ to reach the outcrops, continue westward to ’10-1alt’ to cross the stream course further up the gully. Climb the outcrop WNW to ’10-2alt’. Then veer right (ENE) to follow the top of the outcrops mostly along slope to rejoin the described route at ’10-2′. This worthwhile small diversion increases the total walk distance by only about 0.3km.
