Very curious! Nothing spectacular, but it is worth going to see if you are around Bodo. Tourist information offers information on the hours which you can witness this curiosity as it only occurs during low tide. It is a fjord so narrow that when the tide is low, currents produce unevenness in both directions causing the formation of thousands of swirls. It is about a 30 km drive, cross a big bridge and from this bridge are the best views. Some eddies reach a height of ten meters across and five meters deep and with a speed of 40km.
