Blue Lake, Mount Gambier, South Australia.

Blue lake in Mount Gambier has been a popular tourist stop for a long time. I remember stopping here 30 odd years ago when I was driving around Australia in my little Toyota Corolla station wagon with a couple of friends. I don't remember much from the trip, that far back, other than I was surprised that the water in this crater lake was indeed very blue. I am always very skeptical as usually most or at least some of these types of tourist attractions are only worthwhile when there are ideal weather or environmental conditions. I am happy to report that the blue lake has been worth the visit, the three times I have been there and one was even in the rain. They reckon this extinct volcano lake stays blue because of a limestone layer and the remains of marine organisms over millions of years. After reading that I was then wondering if it was a good idea to be actually drinking from the local water supply as it is pumped from this very lake. I am also happy to report that the water tasted fine and left will no side effects, that we know off.
