Are you ready to explore the depths of the earth and wade through subterranean rivers, marvel at the phosphorus glow worms, cross chasms and explore the caverns of this unique granite boulder cave!

Our route follows an underground river which flows from one end and out the other! We will negotiate giant boulders, some tight spaces, huge drops and fast flowing rivers.

This supercharged adventure day combines two exhilarating adventures; White-water kayaking on the Yarra river and adventure caving at Britannia caves.
