The Blue Lake and The Umpherston Sinkhole are a definite stop on the way to Adelaide (if you’re traveling from Melbourne to Adelaide, or, on the way to Melbourne, you’re traveling from Adelaide to Melbourne) or well worth a visit to just this place. The lake itself is amazing to look at and the surrounding areas are nicely equipped with walking/jogging tracks, BBQs and restaurants. The lake is in “full color” during summer.
