Red Rock Reserve is situated about ten kilometres north of Colac, Victoria, Australia. It is a major volcanic site and consists of several maar craters which, at times, fill with water forming small lakes.
It is a sleeping volcano and there has been no activity for about 10,000 years.
There is a look-out on Red Rock which overlooks the craters and the rich volcanic plains. It also overlooks Lake Corangamite. This lake is the largest in Victoria, but does not sustain any water creatures. It is seven times saltier than the ocean!
