Whungee Wheengee Canyon

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. Duplicate row whungee-wheengee merged 2026-08-21 (EXECUTE-PLAN.md 5.4): identical route, identical grade, no unique data. Its coordinate (-33.4757, 150.3742) sits about 3.1 km from this record's; no source settles which point is the trailhead, so the conflict is recorded rather than resolved.
