From the start point (at waypoint ‘START’) head NNE and follow a minor but well-defined narrow track up the gentle slope. The track veers northward at ‘1-1’, crosses a small gully, then veers right at ‘1-2’ to head upslope via ‘1-3’. Continue northward on the track as it climbs gently uphill through quite dense Pingle (Dryandra squarrosa) shrubland. At about ‘2’veer right to leave the track and head NE up the steepish hillside, picking the easiest route through the shrubland. Veer ENE at ‘2-1’. The slope flattens before you reach ‘3’ near the hilltop. (At 371m this hill top is only a few metres lower than maximum elevations of 374m which occur on local hilltops along a ridge about 1km further east. Boyagarring Hill doesn’t have a single, distinctive summit). Veer right (ESE) and descend to soon reach a flat area at ‘3-1’ where small outcrops are broken by patches of heathland. Continue to ‘4-1’, then veer sharp left and head roughly northward via ‘4-1’ and ‘4-2’. At ‘5’ veer left (NW) along the south side of a gully which narrows and deepens northward. Veer right (northward) at ‘6’ to soon cross the gully and traverse a steepish pebbly slope through woodland before crossing two more narrow gullies.Veer right (eastward) around a steepish hillside via ‘7’ and ‘7-1’, then veer NE-ward to reach an outcrop after ‘7-2’. Cross the outcrop via ‘8’ and ‘9’ and head northward, crossing another gully at ‘9-1’ and reaching a broad laterite-capped ridge at ‘10’. Veer right (eastward) partly though denser shrubland, to soon reach a rocky laterite breakaway at ‘10-1’, from where there are good views to nearby farmland to the north. Veer ESE, partly continuing through the open wandoo woodland along the slope below the breakaway and in places partly through the shrubland/light forest above the escarpment . At ‘11’ veer left to head downslope and eastward via ‘11-1’. Veer right (ESE) at ‘12’ initially along slope, then at ‘13’ veer right (SE) to descend to cross a stream course at ‘13-1’. Climb gently again into open woodland via ‘13-2’ and cross another stream course. Turn sharp right at ‘14’ and head SSE gently uphill to soon reach (at ‘15’) an eastern breakaway slope with a view east through the open wandoo woodland to wheatbelt farmland. Turn right (SSW) to cross the crest of a small spur ridge at ‘16’. Veer right (WSW) across the head of a small rocky gully to reach a broad, flat granite outcrop at ‘17-ROK’. Continue WNW across the outcrop for 200m, gaining a view northward over the woodland down the valley. This outcrop is at about the halfway point on the walk and is a nice spot for a rest break and/or lunch. At ‘18’ veer sharp left (initially WSW) and climb uphill through shrubland via ‘18-1’ to reach wandoo woodland again on a local hilltop on the ridge. (This ridge is effectively the summit ridge of Boyaggaring Hill and this hill top is one of the two equal highest points along the ridge with elevation of 374m.) Veer left to head SE gently down the ridge, and through some fairly open Parrot Bush shrubland to reach (after about 400m) the edge of the laterite-capped plateau (or mesa). Veer ESE at ‘19-1’, to descend the upper breakaway slope to reach at ‘20-RK’ a distinctive rock hollowed by weathering. Continue along slope to reach the edge of a gully at ‘21’. Turn right (SW) to follow the north slope of the gully, then at ‘22’ turn left (SSE) to cross the gully. Continue SSE via ’22-2′. (Or see Option below for a shortened walk.) Skirt patches of thicker shrubland if necessary and soon reach an open slope covered in quite thick, medium heath, with views to nearby farmland. Follow a kangaroo trail near the upper edge of the heathland and soon descend to reach the Park boundary vehicle track at ‘23’). Follow the track southward for about 300m to a gully at ‘24’then veer off-track SW through fairly open mixed wandoo-jarrah forest. Veer right (westward) at ‘25’ to cross the crest of a ridge. Continue westward around the south-sloping hillside via ‘25-1’ and ‘25-2’. Cross the crest of a broad spur ridge at ‘26’, picking an easy way through patchy shrubland, then veer right to head NW downslope through woodland and reach a thicket of sheoaks flanking a stream gully. Pick an easy route through the fairly dense thicket to reach a small granite outcrop at ‘27-RK’ marked with a very small cairn. Cross the adjacent stream course and head westward up a steepish hillside. Veer NW at ‘28’ to reach the laterite-capped plateau at the top of the breakaway. Continue NW across the plateau via ‘28-1’ through relatively open jarrah forest and patches of Parrot Bush. Descend NW along the upper slope of the breakaway and cross a small gully before climbing to a narrow rocky, laterite-capped promontory at ‘29’ and gaining a view westward across Gibb Gully to the nearby State Forest area. Veer right (NNE) to cross the nearby gully at ’30’, then head roughly NW along slope via ‘31’. ’31-1′. Veer westward along the steepish breakaway slope at ‘31-1’. Cross a stream course at ‘31-2’ and continue downslope to rejoin Pike Road at ‘31-3’. Turn right to follow the road NW for just over 100m to return to the start point.
Option, for shortened walk (13km) after waypoint ‘22’: You can bypass the SE section by taking a short cut from ‘22’ to ‘RK2’: Continue SW up the gully from ‘22’ through open woodland to reach the crest of the ridge and the edge of an area of quite thick Parrot Bush and Pingle at ‘Alt-22-1’. Then head WSW, following kangaroo trails and gaps in the denser shrubland to reach ‘Alt-22-2’. Then veer SW again to soon leave the shrubland and re-enter open mixed forest, heading gently down the valley to rejoin the route as described above at ’27-RK’. This short cut reduces the total walk distance by about 1.6km.
