Mount Gambier is located midway between Adelaide and Melbourne. Visitors can get to Mount Gambier by plane from either of these cities, by car or by bus.
The Blue Lake is located in the crater of a volcanic crater and is the main source of water for the city. During the year the colour of the lake changes from an ocean grey colour to a bright irridescant blue. The Blue Lake is one of three crater lakes located on the southern edge of the city: the others are Valley Lake and Leg of Mutton Lake.
