Highlights
Outing Highlights
One of five such caves in Victoria
This cave system is uncommon in the state — only five like it are known — making the geological forms and hidden chambers here an unusually precious subterranean playground.
Subterranean rivers, chasms and tight squeezes
Expect to wade through underground streams, negotiate chasms and move through tight, hands‑on squeezes as you progress through the cave network — this is true adventure caving rather than a walk‑through tour.
Glow worms and cave life
The cave houses a small but striking subterranean community — glow worms, cave crickets and fungi — revealed as you move into darker chambers and crevices.
What the day feels like
What the trip feels like
This is hands‑on spelunking: formed by millennia of flowing water, the granite boulders create tight passages, hidden caverns and pooled streams. Over roughly two hours you’ll scramble over rock, crawl on hands and knees, slide past narrow sections and wade through subterranean rivers, with the occasional chamber offering the luminescent spectacle of glow worms. Multiple entry and exit points mean the route can be adapted to the group, but be prepared to get wet and muddy — the trip is physical and immersive rather than a casual tour.
