Whungee Wheengee Canyon

verified ACA 3B High flood risk Mount Wilson, NSW

Long, narrow Mt Wilson area canyon with dark duck-under tunnels and an extended cave-like middle section, a step up from Claustral in commitment.

The current standard exit crosses private property; the published alternate exit track is the polite choice. Pack a head torch with backup batteries: the dark cave sections genuinely need them.
