Iceland is home to a stunning collection of waterfalls, with all shapes and sizes available for the delight of nature seekers. Yay! Far on the northeastern part of the island lies the mighty Dettifoss, Europe’s most powerful waterfall. How powerful? At 100 m wide and with a drop of 45 m, the average water flow is 200  m3 every second! That’s an Olympic swimming pool every 12 seconds, give or take.
