Shore-access freshwater diving in a clear volcanic lake, best treated as a calm training site with cold water at depth and simple navigation.
About Lake Rotoma
Lake Rotoma is a clear freshwater volcanic-lake dive in the Bay of Plenty, with a simple shore-access training setup and enough underwater relief to make a useful local dive. The appeal is the calm lake environment, clear water, and easy navigation around a point or objective rather than reef-style structure. Plan around colder water at depth and normal lake-side wind changes.
