Head south from the carpark (at waypoint ‘START’) and past the toilet block at ‘1’ to meet an unsealed road at ‘2’. Follow the road southward up the narrow side gully. After the road crosses the stream to the east bank at ‘3’, take the right-hand, southward fork. The road then continues climbing along the gully, initially steeply, before re-crossing the stream at ‘4’. At ‘5’ veer left off-track and navigate up an around the hillside through the forest via ‘6’, ‘6-1’ and ‘7’. Scramble up onto an outcrop at ‘7-1’ and cross the main gully again at ‘8’ at a rock ledge above a nice cascade when the stream is flowing. Walk upstream for only 30m along the sloping north bank through heath to ‘8-1’, then turn left to head upslope on a granite outcrop. At ‘9’ veer left and pick an easy route through a belt of shrubland to reach a rock promontory at ‘9-1’. Descend a little to ‘9-2′, then veer right (NNW) to cross a small gully on the north side of the outcrop and head up the hillside through mostly open forest to reach a flatter section after ’10’. Continue mostly along slope via ‘10-1’, ‘11’ and ‘11-1’, across some very open ground with patches of heath and balgas, gaining good views to the NW. Take in the view westward across the side valley to Baldwins Bluff (the rock slopes are hidden from here) and down the lower Serpentine River valley and across the Swan Coastal Plain. Veer right (NE) on a rock slab at ’12’ and pass a roughly constructed rock seat with a view at ‘12-1’. Cross the crest of a gentle spur ridge through a patch of wandoo woodland and reach a dark (dolerite) rock slab at ‘13’ near the head of a gully which drains steeply northward into the main valley. Veer ESE up the flank of the gully, then eastward at ‘14’ through open jarrah forest to meet a vehicle track at ‘15’ on the crest of a ridge. Turn right to follow the track eastward. When it soon (in less than 100m) bends to the right at ‘15-1’ continue off-track through forest along the laterite-capped ridge to meet a vehicle track along the edge of cleared land (a former farm). Turn left to follow the track around the edge of the open land to reach a communications tower at ‘17’. Turn left (northward) to follow a track to the north side of the tower. Then descend off-track through forest across the short, steepish laterite escarpment to ‘18’. Emerge from the forest onto an open rocky slope with scattered large balgas and great views across the main valley and up Gooralong Brook valley. This is a good spot for a morning rest stop (though no shelter if wet weather). Walk along slope via ‘18-1’ then descend NE-ward via ‘18-2’ and ‘18-3’ down the steepening slope. At ‘19’ reach a rocky promontory above the steep and rocky valley slope with a view down to the historic Spencers Cottage near the Serpentine River and northward up the Gooralong Brook valley. At ‘19-1’ cross fairly open ground on the crest of a gentle, north-plunging spur ridge, then descend steeply (via ‘19-2’) to reach a former farm road at ’20’ on the SW flank of Carralong Brook valley. Turn left to follow the road down the hill to a T-junction with a road at ’21’. Turn right (northward). The road here runs within 50m of the east bank of the Serpentine River. Soon pass within 100m of Spencer’s Cottage at ‘21-1’. Soon after the cottage veer left off the road to cross the Serpentine River by a small bridge at ’22’ (and note the nearby historic wooden bridge immediately upstream). Then follow another dirt road (Selkirk Road) northward, skirting a strip of farmland above the western bank of Gooralong Brook. After about 200m, at ‘22-1’, take a short, optional diversion down to the Brook to ’22-2′ where a waterfall flows well after good rainfall. Return to the road (at ‘22-3’) then after only a further 100m veer to the right, off the road, across a grassed area to follow the well-trodden foot-track (Kitty’s Gorge Trail) north along the Brook. After about a further 500m (at ‘24’) the trail crosses a side gully and soon starts to climb. The Brook below drops 25-30m over granite rocks along the gully, over a distance of about 170m, and can be seen to the right cascading over granite outcrops; Very impressive after winter rain! Several optional short diversions to the right of the trail at ‘24-1’, ‘24-2’, ‘24-3’, ‘24-4’ to viewing points or down short sidetracks, provide better, worthwhile views of the cascades if the Brook is flowing strongly. Pass close by another good waterfall at ‘25’ (‘Little Wave Rock’; WalkGPS informal name). The trail then flattens out again. Soon after crossing a vehicle track (at ‘26’; with an optional Brook crossing point just to the right) reach a sidetrack on the right at ‘27’. Follow this across a footbridge over th Brook below a flow-monitoring weir. (Or see Option 1 below for a short-cut to reduce the walk distance). After crossing the Brook follow the road quit steeply uphill via’ 28’ approx. SSW. (Or see Option 3 below for an excellent off-track alternative). After ‘28-1’ the slope soon eases and the the track veers SW, reaching the crest of a ridge at ‘29’. It then curves tightly eastward up the flank of the ridge and at ‘30’ turns northward, soon reaching a foot-track on the left at ‘31’, which is the continuation of Kitty’s Gorge Trail. Follow the foot-track around the steep SE flank of Gooralong Brook valley via ‘31-1’, ‘31-2’, ‘31-3’. There are some good views west across the valley and to the coastal plain from a couple of large rock outcrops, which also offer nice options for a lunch stop. (This is about the halfway point on the walk.) The foot-track veers eastward to meet a vehicle track at ‘32. Head NE along the road around the top of the hillside. At ‘32-1’ the road veers north and soon begins descending. When the road veers right at ‘33’, continue downslope off-track to soon meet another vehicle track at ‘33-1’. Follow this road NNW down the spur ridge to a junction at ‘34’, passing a pine plantation on the right which lay within the former Gooralong camping ground. Pass the entry to the Kitty’s Gorge Trail on the left and follow the road to the left (not straight ahead) to cross Gooralong Brook at ‘35’. You now have a short, steep climb (about 30m vertical gain) up the vehicle track. At ‘36’ veer left to head WSW up through the forest. Cross a gully at ‘36-1’ then climb SW-ward to join at ‘37’ an old forestry road which runs SW and then west around the flatter margins of the hill top via ‘37-1’. After ‘37-2’ the track descends over a distance of 200m and then crosses the head of a gully. At ‘38’ veer left off-track through open forest, soon crossing a small outcrop at ‘38-1’. Then head southward down a narrowing ridge and cross a rocky promontory at ‘38-2’. At ‘39’ veer sharp right (west) and descend briefly to cross a narrow, steep-sided gully at ‘40’. (In spring, keep a look out for the White Spider Orchid along this section of the walk.) Continue roughly southward up slope to ‘41’ (from where there is a view SSE down the gully and across Gooralong Brook and Serpentine River valleys.) and then descend via ‘41-1’ to another narrow, rocky ridge at ‘42’ with more views. Pick a way downslope via ‘42-1’ and ‘42-2’ through patches of denser heath, following animal tracks wherever possible to avoids scratches. Cross a rocky stream course at ‘42-3’ above a small waterfall. Then continue southward, along slope to soon meet Selkirk Road (rough, unsealed) at ‘43’. Turn left to follow the road back down to Gooralong Brook and (via ‘44’) re-cross Serpentine River and pass Spencer’s Cottage again, retracing your steps of the outbound part of the walk. Follow the vehicle track/road around the southern bank of the Serpentine River to ‘46’. Then turn right at the marked Kittys Gorge Trail at ‘46’ and follow the foot-track to ‘47’ which is close to the river bank. Before leaving the river bank to follow the foot-track up slope to ‘48’ it’s worthwhile continuing down the riverside to reach at ‘47-1’ a swimming hole formeed by an old concrete dam wall across the Serpentine River. On a hot day this is a great place for a cool dip near the end of the walk!) Then either back-track via ’47’ to reach ‘48’ or continue along the south bank to follow an alternative foot-track upslope via ‘47-2’. Rejoin the road at ‘48’ and follow it westward for 200m to ‘50’ where a track on the right leads you steeply downhill along the north side of the water pipeline. Then cross the River from ‘51’ to ‘52’ via the pipeline pedestrian bridge. It’s less than 200m back to the strat point from here. But if you haven’t previously visited Serpentine Falls make sure you turn right at ‘52’ to make the short walk (200m) to the Falls viewing area at ‘52-1’. From ‘52’ head westward down the road to cross the bridge across the Serpentine River (at ‘53’) to get back to the Start point at the carpark.
Option 1, Shorter walk distance (via short cut ’27’ to ’34’): If a shorter walk distance is preferred, you can bypass the section of the route on the east side of Gooralong Brook. That is easily achieved by continuing northward along the Gorge directly from waypoint ‘27’ to ‘34’ instead of crossing at ‘27’ as per the described WalkGPS walk route. That simple option reduces the total walk distance by 2.6km to about 15.5km without sacrificing any of the interesting walking in the seldom-visited areas to the south of the Serpentine River valley.
Additional options, Existing trails: Shorter walk options (mainly using part of Kitty’s Gorge Trail and Stacey’s Trail) which exclude the southern loop to Serpentine Falls are more suitable for inexperienced walkers and/or warmer weather when the full walk will not be comfortably enjoyable. Published maps for some of the local trails (including Stacey’s and Kitty’s Gorge) are also available online from the Jarrahdale Heritage Society (see “Other Info.” on this page). Stacey’s Trail is a 1.7km loop between Jarrahdale Cemetery (on Atkins Street) and Kitty’s Gorge Trail. This passes through a small area of beautiful virgin jarrah forest. It can easily be added as a variation to the WalkGPS walk route on this page, especially if you prefer to start from the Cemetery car park at the Jarrahdale end and leave out the southern loop of the route (south of Spencer’s mud cottage).
