Gibb River Road — Mornington Wilderness Camp to Mitchell Falls via Kalumburu Road Junction and King Edward River
Four tiers of falls, zero forgiveness.
Mitchell Falls — or Punamii-Uunpuu in Wunambal Gaambera language — doesn’t give itself up easily, which is precisely the point. The run north from Mornington Wilderness Camp picks up the Gibb River Road briefly before swinging onto the Kalumburu Road, one of the Kimberley’s most punishing corrugated surfaces. King Edward River crossing is the first checkpoint — in a good year it’s a fast-moving but shallow rock ford; in a bad one it will turn you around and not apologize. Past the crossing, the Mitchell Plateau Track branches west toward the falls carpark. The track is narrow, deeply rutted red clay that turns to greased glass in the rain. The falls themselves drop over four tiers of Kimberley sandstone into a croc-inhabited plunge pool — you look, you don’t swim.
This spur is rated difficult to expert depending on the season and recent rainfall. High-clearance 4WD is the bare minimum; dual rear lockers make a real difference on the plateau clay. Best window is June through August before the build-up makes crossings unpredictable. A camping fee applies at Mitchell Falls (Wunambal Gaambera Country — pay at the ranger station). Fuel at Drysdale River Station is your last reliable source before committing north; carry a full spare and recovery gear because EPIRB distances are real up here. Cell service drops to zero past Imintji and doesn’t return until you’re back near Kununurra.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this stretch, or do I need lockers?
Stock high-clearance 4WD will get most people through in dry conditions, but lockers are strongly recommended — the King Edward River crossing and rocky approaches to Mitchell Falls can punish open diffs fast. Mud terrain tires and a snatch block setup are not optional gear here.
When does this road actually close, and what happens if the wet season catches you?
The window is roughly June through August — the dry season. Roads into Mitchell Falls close entirely during the wet (October through April) and can stay shut well into May depending on rainfall. Getting caught by early wet season storms here isn't an adventure, it's a recovery operation.
Do I need a permit to drive to Mitchell Falls, and is there a fee?
Yes — you need a Miinimbi Country permit from the Wunambal Gaambera Aboriginal Corporation to access this country, plus standard WA national park entry fees apply at Mitchell River National Park. Sort the permit before you leave Kununurra; there's no buying it at the gate.
What's the hardest section of this route and what should I actually expect?
The Kalumburu Road north of the junction throws relentless corrugations, loose creek crossings, and sharp rock sections that eat sidewalls. The King Edward River crossing is the critical chokepoint — depth and current vary with season, and there's no bypass if it's running high.
How far is it between fuel stops, and is there anywhere to resupply on this stretch?
Fuel is available in Kununurra before you head out and at Kalumburu (the remote community at the end of the Kalumburu Road) — that's it. The 266km leg covered here has nothing in between, so carry a minimum 60-litre reserve on top of your main tank and don't count on Kalumburu having what you need beyond fuel.
