Hornborga lake is located between the two large lakes Vänern and Vättern north of Gothemburg in Sweden. Cranes are gathering in large numbers here every year to dance and mate before going to their final summer destination further north in Norway and Sweden. Every day there are 8.000-10.000 cranes in this relatively small location. People are coming in large numbers to watch the cranes and it is a real show they are putting on here.
