Leaving from the Mount Aiken Track make your way past the Devils Punchbowl Falls until arriving on the high alpine ridge. Once there start descending northeast which will take you into the upper basin. By now you should be able to spot the couloir which is surrounded by rock walls. Now start making your way up the main valley as it bends to the north. Arriving at the base put on your crampons and start climbing the semi technical line until arriving at the high point which is a low col. From here you have a great view of the backside of Temple Basin so take in the view before riding back down into the valley below.

Once back in the basin start following the drainage up towards the low col between Mount Cassidy and Blimit Peaks. While I can imagine this climb is a relatively easy skin in powder conditions there is a good chance you will have to bootpack it with crampons on. Once on the high ridge you can ride down the northwest facing slopes which will take you to the Temple Basin Ski lodge.

For the final push of the day you need to make your way down the Temple Basin track which arrives at the ski fields parking lot. Remember that your car is a few kilometres away so it is good to have two cars or more than enough daylight so you can hitchhike back.
