Central and eastern Germany, where I live, are rich in inland lakes, the majority of which were formed during the last ice age. In particular, the area around Berlin is richly blessed with such lake scenery. These are often connected with each other, so that one can easily go water hiking, e.g. by kayak. Further south in Saxony and Saxony-Anhalt, wonderful new lakelands are being created because old open-cast coal mines have been flooded and renaturalised there for decades.
