Formed over thousands of years by water erosion, a jumble of huge granite boulders near Yarra Junction hides one of only five known cave systems of its kind in Victoria. In a compact, roughly two‑hour outing you’ll scramble, wade and crawl through chasms and subterranean streams, peer into caverns lit by glow worms and encounter a small underground ecosystem of cave crickets and fungi.

THE RARITY

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.

THE ROUTE

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.

THE ECOSYSTEM

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.

Suitability

Who it's for

Who this trip suits — and who should think twice.

1
Active families (children 10+)Good match for families with children aged 10 and older — the minimum age is 10 and the shorter, two‑hour format makes it accessible for adventurous kids who can crawl and scramble.
2
Adventure seekersIdeal for people seeking hands‑on, physical caving rather than a passive cave tour: expect crawling, sliding and getting wet and muddy.
3
People with mild claustrophobiaPotentially suitable — multiple exits and entries mean the route can be adjusted, and operators note that even some claustrophobic visitors enjoy the trip.
4
Those with limited mobility or medical constraintsNot ideal: the experience requires crawling, scrambling and negotiating uneven, wet terrain, and is described as quite physical.
