From the south, come through Boyup Brook or Donnybrook if you are coming from the south east or south-west, respectively. If you are coming from the south (ie via Bridgetown) it doesn't make much difference; there is a good gravel road from Balingup to Noggerup which takes less than 10 minutes off the journey, but isn't recommended at night.
For GPS users, our address is 1913 Preston-Collie Rd, Mumballup, and our front gate is at latitude -33.525 (south) and longitude 116.115 (east). If you rely on your GPS you may be taken through Collie, or through Dardanup and Wellington Mill (Ferguson Valley), both of which represent slightly shorter distances but similar driving time, due to winding roads and lower speed limits. Both routes are better saved for your daytime touring or return journey, as they are quite scenic but pass through forested areas where kangaroos can be a hazard at dusk and at night.
Mumballup is at the intersection of the Preston-Collie Road, which runs south from Collie, and the Donnybrook-Boyup Brook Road, which runs east from Donnybrook and north-west from Boyup Brook. Mumbles is 300m north of the intersection on the eastern side of Preston-Collie Road.
From Perth, driving time is about two and a quarter hours in good traffic conditions. There is no fuel or food for the first one and a quarter hours, so get some before you get on the Kwinana Freeway. Take this and the Forrest Highway south until you get to the big roundabout at Bunbury; take the first exit ("BSN" slip lane) on to the Bunbury Bypass, and turn left after about 3km on to the South West Highway for Donnybrook (second set of lights after roundabout). Pass through Donnybrook and take the Donnybrook-Boyup Brook road turnoff on the left, just outside town (signposted to Collie via Mumballup, also Boyup Brook and Kojonup). The Mumballup junction is about 28km from this turnoff; turn left (signposted to Collie) and Mumbles is 300m up on the right.
Note: The Donnybrook end of Donnybrook-Boyup Brook Road is Blackwood Road, and the Collie end of Preston-Collie Rd is variously Patterson Street, Preston Rd and Collie-Preston Rd (don't ask why; we only live here).
Don't laugh, lots of people do! That's because we're on the Bibbulmun Track; south of Collie and north of Balingup, between the Yabberup and Noggerup shelters. That puts us only 371km from the Kalumunda end, and only 632km from the Albany end!
The track goes around our place on two boundaries, but we really don't mind you taking a short cut if you fancy a hot shower and a warm bed. Open sided unfloored shelters along the track are part of the Bibbulmun experience, but not necessarily every night! We are a "hut and a half" from Collie or from the Grimwade shelter, so by stretching a couple of walk days you can pamper yourself, wash your clothes and soothe your aching limbs for a couple of nights without breaking your schedule.
