Phytophthora dieback: why you stay on the track
A practical Nambung note on dieback hygiene — unmarked tracks are management-only, clean vehicles, and why shortcuts through the heath are not harmless.

Nambung looks empty between the pillars. That is not an invitation. Official visitor guidance is to stay on marked roads and trails. Shortcuts spread dieback and damage formations.
Phytophthora is a plant-disease problem, not a vibe. It moves in soil on tyres, boots and bike treads. You will not see it happen. The damage shows up later as dying vegetation and more fences.
This article is unofficial practical hygiene. It is not a pathology paper. If an alert adds a wash-down or a closure, that alert wins over anything here.
What visitors should actually do
Drive the one-way loop. Park in bays. Walk signed trails. Clean mud off vehicles when leaving sandy or wet sites. That is the hygiene. It is not complicated and it is not optional.
If you want to be among formations, use the signed Desert View Walk (and its accessible first section / lookout as signed). Do not invent a circuit through yellow sand because the loop felt “too road-like.”
Kids copy the first adult who steps off. Brief in the car: boots stay on the path. The empty look of the desert is a trap.
Why the sand is not a trail
Soft sand between pillars compresses, channels water, and becomes the next person’s path. Multiply that by a summer of coaches and you have a scar.
Formations themselves are not climbing holds. Climbing is a separate safety and damage problem; this article is about the ground. Both rules apply at the same pillar.
Photography: longer lens, lower angle from a bay, or the signed walk. You do not need a secret corridor. See the photography article for light vs coaches.
Vehicles, bikes and the loop
The standard visit is a 2WD sealed approach and a one-way desert loop with pull-over bays. Caravans, trailers and vehicles longer than 7 m are commonly kept off the loop — use long-vehicle bays at the Discovery Centre. The 7 m / trailer rule is [VERIFY] on live drive notes; do not take this site as the sign.
Motorbikes and bicycles on the loop: treat as banned unless a live official page says otherwise (alert from 30 Sep 2025 still listed 20 Aug 2026). That is hygiene and safety, not a sport debate.
Do not create a second set of wheel tracks beside the loop because someone is photographing. Wait for the bay.
Not the same as “leave no trace camping”
There is no camping in this park anyway. Town beds are Cervantes / Jurien Bay / Lancelin. Dieback is a plant-disease problem, not a litter lecture. Both still matter. Pack out rubbish either way.
Do not bury orange peels in the heath as a “natural” gesture. Do not empty a sandy shoe into a drainage line as if that were cleaning it.
Dogs and off-path exploring are separate rule sets. [VERIFY] current pet rules. When in doubt, leave pets in town and people on the timber / sealed / signed surfaces.
Alerts, works and when to stay home
Official alerts can close loops, ban classes of vehicle, or add hygiene steps. Check alerts.dbca.wa.gov.au and Explore Parks WA the morning you drive. A snapshot on this site is not live.
After rain, mud is the vector. That is a reason to be more careful, not a reason to “test” an unmarked track because it looks firm.
If staff or contractors are working, do not drive around them through vegetation. Wait. The desert is not a rat-run.
Failure modes
“Just this once” photo between pillars. Fix: signed walk or a bay. Delete the shot if you already left prints — then do not repeat it.
Following someone else’s footprints so it “doesn’t count.” Fix: it counts more. You just widened the scar.
Bike on the loop because a 2019 blog said it was fine. Fix: live alert, not nostalgia.
Cleaning the car by spraying mud into the next bush. Fix: follow official wash / clean advice; do not relocate the problem one metre.
Where this sits on the site
Visit hub for rules and safety. Pinnacles Drive and Desert View Walk for the legal photo product. Yued Country article for the respect layer that is not dieback but still says stay on the track.

FAQ
Tap a question to expand the answer.
Is it OK if I only step off for one photo?
No. Use pull-over bays and signed lookouts. One set of footprints becomes a social trail.
Do I need a special wash station?
Follow whatever Explore Parks WA / DBCA currently publishes for Nambung. Baseline: stay on marked surfaces and clean mud off vehicles when leaving sandy or wet sites. Extra infrastructure is official, not this site.
Are bikes allowed on the desert loop?
DBCA has listed motorbikes and bicycles as banned on the Pinnacles Desert loop (alert from 30 Sep 2025, still listed 20 Aug 2026). [VERIFY] live alerts before you pack a bike. Walk and 2WD loop are the visitor product.
Is this the same as leave-no-trace camping?
No. There is no camping in this park. Dieback is disease hygiene. Pack out rubbish either way. Do not confuse the two lectures.
