Forty minutes out of Byford the bitumen runs out of hills and drops you into jarrah forest, and that's roughly where Dwellingup starts to feel like a proper weekend rather than a day trip. I've done this run three times now in the van, twice with the bikes on the back rack and once without, and the version with bikes is the one worth telling you about.
Camping at Dwellingup for a Munda Biddi weekend is one of those trips that sounds like it needs more planning than it does. You've got a small forest town, a couple of solid campgrounds nearby, and one of the best short sections of the whole Munda Biddi Trail right on the doorstep. What trips people up isn't the riding, it's working out where to actually park the van and where the next dump point is once you're out there.
Why Dwellingup works as a base camp
Dwellingup sits inside the broader Lane Poole Reserve area, managed by the WA Dept. of Biodiversity, Conservation and Attractions, and that matters for van campers because it means the campgrounds have proper facilities rather than a bush clearing and a fire ring. Nanga Mill and Baden Powell are the two most people head for, both with drive-in sites, and both close enough to town that you can duck in for supplies without losing half a day.
The town itself is tiny but it's got what you need. The bakery and general store on Marinup Street cover breakfast and dinner supplies, and the Forest Heritage Centre is worth a look if the weather turns and you need somewhere dry for an hour. I'll admit I underestimated how much I'd end up relying on that main strip for small things — forgot a gas canister once and Marinup Street sorted me out inside ten minutes.
Getting the trail into the weekend
If you've never ridden any part of the Munda Biddi, Dwellingup is a genuinely good place to start because the sections either side are graded for people who aren't racing snakes. There's a solid write-up on what a day on the Munda Biddi Trail's Perth Hills section actually looks like if you want to see what the northern stretch is like before you commit the van to the trip.
For a weekend based out of Dwellingup, most riders do a loop or an out-and-back rather than a point-to-point, mostly because it saves the hassle of a car shuffle. The Carinya Loop - Munda Biddi Trail is the one I'd point a first-timer towards. It's manageable in half a day, gives you real jarrah and marri forest without any brutal climbs, and drops you back near camp in time to get the fire going before dark.
If you'd rather walk than ride, or you've got someone in the group who isn't keen on two wheels, the Wiilman Bilya Trail follows the Murray River section and is a nice contrast to the forest riding. We did it as a rest-day activity last time and it worked well — legs still tired from the day before, nothing steep, plenty of shade.
Power sites, water and the stuff nobody puts on the brochure
Here's where I get particular, because this is the bit that actually decides whether your weekend is comfortable or a slog. Neither Nanga Mill nor Baden Powell run powered sites, so if you're relying on the van's battery for anything beyond lights and a fridge, bring a decent solar setup or plan your energy budget properly. I run a 200-watt panel and it copes fine through most of the year, but midwinter in the jarrah canopy you'll be shaded more than you'd like.
Water is untreated at both campgrounds, same as most DBCA sites in the reserve, so top up before you leave Perth or grab drinking water in town. Dump points are the other thing people forget to check — there's one in Dwellingup itself, and I'd sort that out on arrival rather than after two nights, because nobody wants to be doing that calculation on empty on a Sunday morning with the van packed and everyone wanting breakfast.
The caravan park question
I'll say the mildly unpopular thing here: the caravan park closest to the main trailhead gets booked out fast and, in my measured opinion, is overpriced for what you actually get on site. You're paying trailhead-adjacent premium for a powered site and not much else that Nanga Mill or Baden Powell don't offer for less, minus the power. If having mains power for the weekend is non-negotiable for you, fair enough, it's the only real option going. But if you can run without it for two nights, the DBCA campgrounds are better value and quieter besides.
Getting there without the van, if that's your plan
Not everyone's doing this trip with a caravan in tow. Some riders leave the car at home altogether and use Transperth services as far as Armadale or Mundijong, then ride the rest of the way in on the trail itself before continuing on to Dwellingup. It adds a decent chunk of distance to day one, so it suits the fitter riders more than the casual weekender, but it's a genuinely good option if you're trying to do the whole thing without a support vehicle.
What a typical weekend looks like
Friday night, most people are rolling into camp late afternoon, getting set up before dark, and having a fairly ordinary dinner because nobody's organised by that point. Saturday's the big riding day — Carinya Loop or further along the main trail depending on fitness and how the group's feeling. Sunday's usually a shorter loop or the Wiilman Bilya walk, then pack up and head home before the afternoon traffic builds on the way back into Perth.
It's not a complicated formula, and said she'd go back every year if the diary allowed it — that's roughly the verdict from the friend I dragged along last time, and I don't disagree. Two nights is enough to feel like you've actually been somewhere, without needing to book more time off work than the trip's worth.
For anyone still working out the logistics, I put together a fuller planning rundown in Camping at Dwellingup for a Munda Biddi weekend, which goes into more detail on booking windows and site availability through the busier months. Worth a read before you lock anything in, particularly if you're chasing a specific weekend in spring when the reserve gets busy with wildflower walkers as well as riders.
The forest doesn't change much year to year, which is part of the appeal. Same jarrah, same creek crossings, same quiet once the generators switch off. It's a short drive from Perth for something that feels a fair bit further from home than it actually is.
