Imagine swimming underwater anywhere. What will one normally see? Sand and rocks. That is not so in the case of the Gruner See – the Green Lake – in Styria, Austria. During the winter, the lake is only 1–2 m deep and the surrounding area is used as a county park. However, during the spring, when the temperature rises and the snow melts, the basin of land below the mountains fills with water. The lake reaches its maximum depth of around 12m from mid-May to June. Beneath the water one can view grass and not sand and mud. Looking up, one can spot the tops of the trees under the water.
A truly surreal experience
