This cristal cave was found in 1682 by a hunter. I was fascinated by the calcite crystals, stalactites and stalagmites, rushing water and the acoustics and lighting. The temperature in the cave is 8.5°C all year round. Besides it's a beautiful area for hiking. I didn't go hiking because it was too hot last Sunday. Can you believe it's over 30°C?!?!
Then I went for a walk along the Lake Constance and I found these sweet young Swans. What a lucky day!
