Scuba Diving at Ewens Ponds
Three shallow spring-fed ponds connected by channels — a drift dive through crystal-clear freshwater.
Ewens Ponds is a chain of three spring-fed ponds connected by shallow channels, and it is the most accessible of the Mount Gambier freshwater sites.
Because the ponds are shallow and open to the sky, the site does not require cave qualification, though a permit is needed and access is time-limited.
The dive is effectively a one-way drift from the first pond to the third, through water so clear that divers describe floating above the aquatic plants as surreal.
Recommended: Any certified diver; many suit supervised try-dives. Parts of the site reach 10 m, which needs Open Water Diver. What can I dive with my cert?
