Gellen
The Gellen or Gellen Peninsula is a tongue of land (a so-called spit) at the southern end of the island of Hiddensee off the north German Baltic coast. Its southern part is protected as an important bird reserve and is part of protection zone I of the Western Pomerania Lagoon Area National Park. It is therefore not accessible to the public.
It consists of post-ice age sand depositions and is growing annually by a few metres to the south. The dredging of the shipping channel between the island of Bock and the Gellen prevents a graded shoreline from being formed, which would otherwise be typical of the eastern Baltic Sea area with its numerous spits.
