Bullock Spur Firebreak is a 1.8 km 4WD trail in Nelson City, Nelson, New Zealand. Expect max gradient up to 91%.
You'll find an extreme test of vehicle capability and driver skill on Bullock Spur Firebreak, a challenging 1.8 km route that demands respect and precision. This firebreak near Nelson City delivers one of the steepest driving experiences in the region, with grades reaching 91% that will test your 4WD's traction and your nerve in equal measure. If you're seeking a trail that separates casual drivers from serious off-road enthusiasts, this is it.
The terrain here is unforgiving—expect a relentless climb that offers little mercy and even less room for error. You'll navigate through native forest with steep, loose surfaces that require constant vehicle control and focused concentration. The narrow firebreak format means limited recovery options, so commitment and mechanical sympathy are essential. Visibility can be limited by vegetation, and loose scree mixed with clay creates unpredictable traction that changes with weather conditions.
Before attempting Bullock Spur Firebreak, ensure your vehicle is in peak mechanical condition with quality tyres offering genuine grip. Come prepared with recovery gear, as extracting a bogged vehicle from this gradient is technically demanding. The trail is currently unrated with no recorded completions on Newtracs, which speaks to its serious nature. Scout conditions beforehand if possible, as recent rain transforms this already challenging route into something approaching impossible. This is a trail for experienced drivers only—one where preparation and respect for the terrain aren't optional extras, they're survival requirements.
