When the sun shines from a clear blue sky and the thermometer reaches a simmering 34°C, there is not really much else to do than to get into the water as soon as possible. So, we were in the middle of Austria, more accurately by the River Traun in Upper Austria—eight people, neoprene dressed and full of expectations, standing on a cliff about three meters above the River Traun, getting ready to jump. This was the spectacular start of a 1.5-hour snorkeling trip in refreshing crystal clear water.
