Denmark’s northernmost point, Grenen, hosts a unique natural phenomenon. Here, two seas meet, namely the Skagerrak and the Kattegat; and the collision of the waves is visible to the naked eye. This fascinating tourist attraction, Grenen, is a spit formation consisting of deposited sand and gravel carried along by the strong currents; and over the last 100 years, this barrier has increased its length by 1 km. As the large beach expanse at the tip of Grenen is continually moving, there are frequent occurrences of lagoons – attracting both playful children and adults, as well as wading birds. Due to the strong and extremely dangerous currents, bathing is strictly prohibited, though. At the southern part of Grenen, a compass demonstrates that Grenen points towards the east.
