Fodor's Expert Review Dettifoss

Europe’s most powerful waterfall dispatches an average flow of 193 meters cubed per second with a breathtaking force that makes the earth vibrate beneath your feet. The immense column of white-foaming water thunders over a 45-meter (147 feet) drop creating a magnificent and formidable vision of the sheer force of nature. Expect to see terrific rainbows when the sun is shining. From the parking lot off Route 862, there’s a 15-minute trail through otherworldly rocky plains. Dettifoss can also be viewed from the east side of the falls off Route 864 as well but this road can often be hazardous in winter so it's vital to check road conditions before setting out.
