The beach of Grenen appears in many of the works of the Skagen Painters, a community that gathered there every summer between 1875 and the end of the 19th century.
Danish national road 40 terminates at Grenen, and it is one of the most popular tourist destinations in the country, with approximately 2 million visitors each year.
The reef is still active and has grown about 1 km northeast towards Sweden over the last century, resulting in a mean annual growth rate of about 10 m. Because of the very strong currents, swimming there can be fatal and is prohibited in the waters around Grenen.
The area surrounding Grenen is the place with the greatest number of observed bird species in all of Denmark.
Sailors long feared Grenen, as many ships have run aground on the shallow reef through history.
