This cache can accessed to within 150m with a 4x4, parking at the trailhead waypoint.
However, I do recommend bringing the MTB bike along for an excellent time.
If you follow the green arrows and cross an amazingly redneck feat of engineering, you will be just a short bush bash from the cache.
Please note, due to increasing theft, preventative measures have been taken to protect this cache.
Remember to minimise your impact on the environment and have fun!
