UK and Europe Roadtrip - Blautopf

Blautopf Spring is a natural spring of a beautiful blue colour and the water is very clear. It is over 20m deep in parts. The water flows through the karst landscape, its caves and crevices, dissolving limestone as it goes and eventually appears as a spring. Depending on how much rain has fallen in the Swabian Alps you can sometimes see the water bubbling up here. Select the photo below to see more.
