Surrey Road

From Manganui Lodge follow the T-bar to the Top Tow Shelter at 1420m. Ascend a small knoll immediately north of the shelter and continue traversing north onto a col above the Ngarara Bluff at 1620m. Proceed up the ridge and veer right to round the left-most edge of the Top Tier of the Organ Pipes. Traverse north to a shoulder immediately under the bluff at the base of Pleasant Valley and ascend the steepening ramp of Surrey Road. Descend directly into the crater. Descent: Back down Surrey Road or the easier North Ridge route.
