How to find it

Head up Hyperventilation, and the the Castle Rocks trail. Once you get to the final ridge to climb to the summit of Castle Mountain you will see a sign to South Castle. Turn right and head down from here.

The trail

It starts off steep and loose, and you will want to take it easy for the first little bit. This then ends dropping you out on a flowy section of trail that rolls down with a drop on your left. This is a great fun section where you can let 'er rip. The trail then feeds into a more classic windy singletrack in the trees section that is just awesome. It kicks out onto River Road, and you head straight across River Road and the trail carries on with more fantastic singletrack, across a bridge and finally out onto Cokato Road..
