OSM Way
Jackasaurus starts at the top of the Urumau Reserve hill and descends the ridge, dropping over large rock drops you can roll or huck, to meet the traverse track. Eventually, once it's open, this track will continue down the ridge to meet Sumner road.
Access Info
From the end of the benched track across LPC land, head straight ahead (towards the sea) and up hill, veering onto a track on the left to find yourself on the top of the Urumau reserve hill.
