Kalumburu is a picturesque mission nestled beneath giant mango trees and coconut palms with two shops and fuel. Ask around if you need any repairs. There's some interesting rock art nearby, and the odd WWII bomber wreck.
The road to Kalumburu deteriorates quickly after the Mitchell Plateau turn-off and eventually becomes very rocky. You'll need a permit from DIA to visit Kalumburu and a Visitors Pass (valid for seven days) on entry from the Kalumburu Aboriginal Community.
