The Darß peninsula in Mecklenburg-Vorpommern, Germany, is a well-known vacation destiny due to its natural beauty and the location on the coast. The Darß is part of the National Park “Vorpommersche Boddenlandschaft” but is also used intensively for agriculture and other natural resources. The aim of this study was the basic characterization of hydrogeology on the Darß peninsula.The Darß peninsula is morphologically divided into the Altdarß (central heights), Vordarß (southern plain), and Neudarß (northern flat area) areas. This trisection also applies to groundwater recharge and hydraulic conductivities for the upper aquifers. The values are in the range of 4 · 10⁻⁶ to 1 · 10⁻⁵ m/s in the Altdarß area but lower on Neudarß and Vordarß.The main recharge area is in Altdarß whereas the marshy areas with shallow groundwater levels in Neudarß lead to high evapotranspiration and a net discharge of groundwater.Groundwater levels sometime fall below the water level of the Baltic Sea. Especially near the coast, this leads to saltwater intrusion with increased salt concentrations in the aquifer and a decrease in availability of fresh water for drinking water production and agriculture.
