Australia
Every late November the crater lake turns from winter grey to vivid cobalt.
A cobalt lake fills one crater while roses and tree ferns descend into a nearby sinkhole. Mount Gambier’s streets sit over a landscape of volcanic rims, limestone caves and startlingly clear groundwater.
Blue Lake occupies a volcanic crater and usually develops its vivid summer colour gradually from November, while Umpherston Sinkhole turns a collapsed limestone chamber into a public garden. Engelbrecht Cave reveals the groundwater system beneath the city, with underwater passages reserved for appropriately qualified cave divers. Crater walks and Limestone Coast food connect those volcanic and karst layers across the city.
