Head about eastward from the start point (at waypoint ‘START’) across a gentle valley floor through open forest with remnants of timber from logging (in what was once State forest but is now part of the Monadnocks Conservation Park). After about 250m cross an old, overgrown forestry track and continue up a very gentle slope to reach the lower edge of a west-sloping outcrop at ‘3’. Climb the outcrop to ‘3-1’, gaining views back to the west to Mount Solus about 7km SW. Continue approx. eastward upslope, initially through fringing heathland, before re-entering forest at ‘3-2’. Cross a gentle hilltop and descend for a short distance to reach (at ‘4’) another outcrop. Head SE-ward to the upper edge of the gently sloping outcrop near ‘5’, then pass through heathland via ‘5-1’ and descend westward downslope to another granite outcrop at ‘6’. This SW-sloping outcrop provides another good view to Mount Solus. Turn right to head SSE across the outcrop. Pass through more heathland via ‘6-1’ and cross another smaller outcrop. Re-enter forest and head along slope through the open forest for about 400m via ‘7’ to reach a small flat outcrop surrounded by heath. Veer southward along the patchy outcrop and through heathland (via ‘8’, ‘9’, ‘9-1’ and ‘9-2’ and ’10’) and re-enter forest at the southern end of this chain of small outcrops to cross a hill top (via ’11’). Veer SW to cross the hill top and then continue down the hillside through forest. Cross an old forestry vehicle track at ’11-1′. Veer southward to soon reach (at ’11-2′) the northern edge of a long (approx. 500m), fairly flat outcrop. Continue southward across the outcrop to about ‘12’, then turn left to walk SE along the outcrop (passing small rock pools and water courses in winter). At ‘13’ veer approx. south, initially through heath, and gently uphill, to re-enter forest near ’14’. Veer SE through forest (which may include patches of possibly dense parrot bush if there hasn’t been a prescribed burn for some time). Ascend a slight slope to cross the crest of a broad ridge then descend via ’14-1’ to reach an eastward-sloping outcrop (at ’15’). This outcrop is about 1.5-2km short of the halfway point on the walk, but is a good spot for a break, unless you are needing some shade. There are excellent views to Mount Cooke, 4.5km NE, and across the valley to the main Windsor Rocks monadnock, 2km east of this walk route. Then head southward, upslope from the outcrop, to re-cross the crest of the narrowed ridge at ‘15-1’. Descend to reach a small outcrop (at ’16’). Veer SE along the outcrop for about 250m to re-enter forest (at ’16-1′). Continue SE to ’17’ through open forest and close to the crest of the stony laterite-capped ridge. Then veer approx. SSW to head down the hill side for over 500m to reach (at ’18’) the valley floor and the overgrown ‘Old Bibbulmun Track’ (which here followed an old logging railway route before being abandoned when the Bibbulmun Track was re-aligned to the eastern side of Albany Highway). Follow the overgrown track SW, close to an area of scattered wandoo trees. The track branches left after about 250m at about ’19’ toward an old timber bridge which is largely concealed behind shrubs partly blocking the north end (- you may need to search a little for the bridge!). Cross the bridge over the stream (a tributary of the Serpentine River), taking special care not to step onto partly rotten timbers (or alternatively you may prefer to cross the stream itself via a track just west of the bridge). Then continue to follow the old track on the south side. After less than 200m (at ’20’) meet a junction with Patens Road (now a vehicle track but originally also part of the old railway system that connected through to Jarrahdale in the late 1880s-early 1900’s during the peak logging days.) Follow Patens Road westward for about 700m and pass the site of an old timber loading platform on the left hand side of the road (near ’21’. Sadly most of the remaining historic timber structure has been destroyed by burns in recent years). Turn right (NE) to leave the road and find a suitable point to re-cross the nearby stream (previously crossed at the bridge). Then head a short distance upslope through forest to reach a small outcrop (at ’21-1′). Cross the outcrop and pick a NE-ward route upslope through fairly thick low shrubs (check for ticks!), cross another small outcrop and re-enter forest. Reach a cluster of large boulders at ’22’. Veer left and head northward via ‘22-1’ across gently undulating terrain, through fairly open forest, and arrive at the southern edge of a larger outcrop at ‘22-2’. Pass through the fringing heathland onto the outcrop and walk north along the outcrop to ’22-3’. Then veer right to pass through a belt of heathland to reach the upper slope of the outcrop. Head NW along the outcrops and back into forest at ’23-1’. Continue along slope through a short section of forest to reach the start of a large west-sloping outcrop at ’24’. Walk down and along the outcrop via ’25’. At ‘26 veer right (northward) and descend through mainly heath and scrub to cross a small stream course at ‘26-1’ on the southern edge of another sloping outcrop. Continue northward via ‘27’ and ‘28’ across the outcrop and another patch of heathland, taking in the good views over the forest to the west and of Mount Solus, 6km WSW. Re-enter the forest at ‘28-1’ and continue northward around th hillside and then descend to cross an old overgrown forestry track at ’28-3’. Soon after cross a small gully (at ’29’), then veer left (NNW) through open forest for about 800m, crossing another narrow, deeply incised gully 200m before reaching an old overgrown N-S forestry track at ‘29-2’. Veer right to follow the track northward. The track branches at ‘30’; Follow the left branch westward to cross a N-S stream (another tributary of the Serpentine River) and meet Thorpe Road (at ’31’). Follow Thorpe Road northward for 1km to get back to the start point.
