Grenen is the place where two seas, The Skagerak and The Kattegat, meet. The coastline here is ever changing by the waves coming from different directions. Grenen is by many believed to be the nothern tip of Denmark, but the real most nothern point is a few km to the west. Nevertheless Grenen is the place many tourist visits for the experience to stand with one leg in each of the two seas. You can walk along the beach to Grenen from the parking lot a few km to the south, or you can take Sandormen (the lugworm) - a tractor-driven tourist wagon.
