Hiddensee 3/67, 4/68 and 5/68") found no usable oil reserves. As a result, the already prepared 5th borehole was cancelled and all holes were refilled in the summer of 1971. Hiddensee was considered a niche for dissidents and dropouts who worked in the summer, often in hotels, restaurants, or as lifeguards. On the small island they were easily controlled, and despite sometimes open Stasi observation, many meetings and incidents were allowed. On Hiddensee there was an intellectual climate, and artists, writers, actors, musicians and scientists retreated here, such as , , Günter Kunert, Kurt Böwe, Harry Kupfer, Inge Keller, , Armin Mueller-Stahl, Christoph Hein, or members of the punk band Feeling B. Nina Hagen implies that she had never been to Hiddensee, but her famous hit You forgot the colour film expressed a "desire for this unusual island".

In 1996, the island won its municipal independence, but they lost it again in 2005 in the course of the municipal reform in Mecklenburg-Western Pomerania. Since then it has belonged to the subdistrict of Amt West-Rügen. Until 1990 the parish belonged to the county of Rügen in the province of Rostock and was in the same year part of the state of Mecklenburg-Western Pomerania.

But this is disputed. Between 1864 and 1865 the island was breached three times by storm floods between Hoher Dünschen Garn and Peterbergscher Garn, a very low-lying and narrow point. Hiddensee was again flooded near Plogshagen by the 1872 Baltic Sea flood on 12 and 13 November 1872. Even today, the island threatens to divide into
