This loop track climbs to the summit ridge in a series of 33 well-graded switchbacks. It offers great views into the Clutha River and Butchers Dam before descending in more switchbacks to the dam. There are grade 5 biking options for those looking for challenging step-downs.

Note there are rock gaps – scout these sections before riding them. Some sections require walking your bike. Do not take shortcuts on the descent as this causes erosion
