We arrived at our caravan park in miserable weather conditions and quickly, as we thought it was about to rain at any time.
About mid-afternoon I was making a Skye phone call to make a booking at The Grampians when our van literally started rocking - it felt like an earthquake. Rex quickly ran out to see if kids were rocking it - NO that was not to be - only one person would do that to us and of course that is Neil. Yes who should be there but Lindy & Neil. They had previously also been at Naracoorte on the Monday night and went to Mt Gambier on Tuesday. Neil was there for work.
It was great to see them. We had the afternoon together and then a pub meal for dinner.
During the afternoon we visited the Blue Lake. Mt Gambier's Blue Lake is unique. There are lots of blue lakes in the world, but no other lake changes colour so dramatically every year. At this time of the year it is not very blue, the colour will start changing in November. Calcite precipitates when the lake water warms during summer. This lake also supplies the town water.
Then we made our way to the Umpherston Sinkhole. Once a cave, formed through the dissolution of the limestone, this sinkhole was created when the top of the chamber fell to the floor of the cave, creating the perfect environment for its 'sunken' garden. This garden is just beautiful.
Our next stop was the Cave Garden. This sinkhole was the original source of water for the early settlers. Walk down into the cave and venture out onto the suspended viewing platforms for an awesome view into the cave.
During winter, storm water run-off makes its way to the cave forming a spectacular waterfall. It eventually enters the underground water system which possibly feeds into the Blue Lake.
Then it was dinner time and goodnight to Lindy & Neil.
