Our favourite kind of livestream.. 💧

Right now, Mammoth Cave’s seasonal stream is in full flow, fed by winter rains from the Nindup Plain to the east.

Mammoth Cave is a stream passage cave - a long, arched tunnel shaped by a well-defined watercourse. It’s approximately 410 metres in length and 25 metres deep, with the stream sitting about 30 metres above sea level.

Water winds through its chambers before travelling 3.5 kilometres underground to Conto Spring on the coast.

Catch it while you can. This natural livestream usually runs from July to October.
