The Bungonia Red Track is an amazing hike, one of the best in the whole state. The track follows the riverbed through one of Australia's deepest limestone gorges and has significant boulder hopping and scrambling. Don't be fooled by the 4.8km distance, this one might take a few hours depending on your pace. Be sure to check the recent weather history since any rain could make the gorge impassable. Also note that there is occasional blasting from the nearby quarry though there are signs advising you of what to do. Clockwise is generally preferred, but consider anti-clockwise for more of a challenge.
