Supplejack

You'll discover raw, uncharted terrain on Supplejack, a challenging 4WD route near Nelson City that offers adventurous drivers a genuine test of vehicle capability and off-road skill. This short but intense 1.2 km track features a punishing 29% grade that demands respect, technical precision, and a well-maintained rig. The steep descent through native bush creates a visceral driving experience where every gear change and line choice matters—this isn't a casual scenic cruise, but rather an adrenaline-fueled challenge that rewards preparation and caution.

The Supplejack trail's compact length belies its difficulty. You'll navigate tight switchbacks through dense Nelson forest while managing significant elevation loss that tests your vehicle's traction, braking, and suspension. Ground clearance is essential, and you should expect rough, potentially slippery surfaces that vary with weather conditions. The lack of previous traffic data means you're venturing into less-traveled territory—bring recovery gear, ensure your vehicle is mechanically sound, and consider attempting this trail with experienced company.

Before heading out, check current conditions and trail updates using the Newtracs app to confirm access and any recent hazards. Given the steepness and technical nature, this route suits experienced off-roaders seeking an authentic backcountry challenge rather than leisurely exploration. The reward for your effort is genuine adventure in Nelson's rugged hinterland.
