Summary

This hike is a hidden gem in the Adelaide Hills close to Adelaide. The circuit trail is 4.7km return, and takes about 2 hours. There is some single track walking trail, fire tracks, forested valleys and some steep trail sections.

The section at the end of Main Valley up on to the fire tracks on Rockdale Hill is very steep with some loose rocks, and involves walking up a waterfall. If walking clockwise, when you reach the waterfall you need to walk down it, and pick up the trail again at the bottom.

The trail on Rockdale Hill, and leading to it from a clockwise direction, is mainly fire track.
