Bush Mill Road

Bush Mill Road near the Upper Karuah River offers one of the most demanding 4WD challenges in New South Wales, where only the most experienced drivers and well-equipped vehicles should venture. This extreme-rated trail demands serious preparation and skill, with a brutal 40% grade that will test both your vehicle's capabilities and your nerve. You'll need a winch to navigate the steep sections safely, and recovery equipment should be considered essential rather than optional.

The 1-kilometre route is deceptively short but notoriously unforgiving, with only four vehicles on record as having successfully completed it. You can expect the journey to take around 1 hour and 48 minutes, though this depends entirely on conditions and your recovery requirements. The terrain combines relentless inclines with technical obstacles that demand precise vehicle control and spotting. The scenery of the Upper Karuah River region provides a remote bushland backdrop, but you'll be too focused on negotiating the trail's challenges to fully appreciate it.

Before attempting Bush Mill Road, ensure your vehicle is in peak mechanical condition, your tyres are suited to extreme conditions, and you have experienced spotters and recovery equipment on hand. This is a trail that separates serious 4WD adventurers from casual weekend drivers. Check the Newtracs app for real-time trail conditions before committing to this punishing route.
