Blue Lake
Excerpt
Vivid blue volcanic lake turns electric in summer—surrounded by scenic drives and panoramic lookouts.
Description
Tucked into the edge of Mount Gambier, Blue Lake is one of those places that makes you pause. Every summer, the water turns a brilliant, almost surreal shade of blue — so vivid it doesn’t even look real in photos. The lake sits inside an old volcanic crater and while you can’t swim in it, the views are incredible. Locals love walking the 3.6 km trail that loops around it, with plenty of scenic lookout points along the way. It’s especially popular from November to March, when the color shift is at its peak.
Even though it’s technically not a limestone cenote, the way it formed — from underground water activity and a collapsed volcanic chamber — makes it a close cousin. If you’re road-tripping through South Australia, this stop is definitely worth stretching your legs for.
