Beautiful crater lake with a very nice easy walk around it. Only blue at certain times of the year, and bluer when the sun is out. Look to the edges for an even bluer tinge, which they claim the entire lake changes to this blue, but I have my doubts. Multiple viewpoints when walking around the lake, or from the many lookouts in Mount Gambier. The Aquifer tour is also worth doing.

WOW! What a beautiful natural wonder of the world. The lake was spectacular. So beautiful and blue. Sitting on the beautiful green grass and looking into the lake was relaxing and grounding. Definitely worth coming to see.

Both my partner and I had been to The Blue lake before. But the day we went it really was blue a stunning blue as shown in my pictures. It's in the middle of January peak tourist season. Not a grey green that sometimes on cold days is seen. Middle of the year more. We went up to the lookout above the lakes and up to Adam Lindsay Gordons memorial also then followed the stairs to the top which is where the famour leap happened of Gordons on the blue lake. I suggest good walking shoes for the stairs upto the memorial and walks around the lake.

There are many viewing points from which to admire this stunning blue lake. If time does not allow for a walk around the lake, drive the road that encircles the lake and stop at the lookouts. It is worth seeing the lake from different sides, especially if the sun is shining, as this affects the blueness! The best view is from Rook Wall Lookout. There is not a lot of parking. From here, there is an underpass to a lower lookout. Or there are stairs up to a wooden sheltered lookout. If you are feeling extra fit, there are steps up to a higher lookout, although the view doesn't really justify the climb. There are informative displays at some lookouts. Interesting to read about the formation and current use of the lake. This is a must-see when in Mt Gambier.

Main attraction of this town. But try to visit in summer so can really see and appreciate the real blue lake showing ink blue colour. Surrounding area is also good to explore and walk around.

So, I was expecting a lovely blue. I saw a black lake. You could tell it has some earthly deposits from the volcano that makes the lake a different colour, however this time of year it seems to be very dark. The walk around it was good and it's still brilliant to look at. I'd like to come back and see it when it's bright blue in summer. Highly recommend coming here while in Mt Gambier or even if passing through.
