Leaving the base area of Turoa start skinning up the home run trail before taking a left on the Branchline run. Keep gaining elevation until just above the Organ Pipes Canyon and here is where you need to start traversing to the west. Because you went above the canyon it is best to do a low angle descent over towards the Mangaturuturu Glacier. At around 2300 meters you can start heading Northeast to start heading for the crater rim. Being that this slope is low angle it is possibly the easiest way to make it up to the crater.

Standing on the high col now make your way north up a mellow ridge until reaching the highpoint known as Paretetaitonge. Having climbed underneath your intended descent you should have a good idea what the snow is going to be like.

Dropping off the Southwest slopes the first few turns are semi steep before its a nice ramp all the way towards the valley. While riding down you must keep in mind that you will have to climb back up so be aware of your energy levels. I was able to ride down to 1800. Looking back up I was a bit intimidated by the terrain as you are semi exposed to potential avalanches. That being said be cautious while climbing out of the basin and it is best to gain elevation and traverse over the Organ Pipes. Once past said gully system you are back in the ski resort boundaries and can ride all the way back down to the parking lot.
