About one kilometer next to the main island lies the dune of Heligoland. At only 1000 meters long and 700 meters wide, the so-called "Bade-Düne" (bathing dune) is not large. But with grey seals, seal banks, Caribbean-like beaches and rare minerals, it offers paradisiacal diversity for families and nature lovers.
A storm tide separated the main island of Heligoland from the dune on New Year's Eve. A stroke of luck: because today it is an oasis for all those who want to spend relaxing hours on the beach and in nature. Turquoise blue water and the finest sandy beaches create an almost Caribbean flair. The stars of the dune, however, are the grey seal and harbor seal colonies.
