The Schlosshotel Münchhausen is reachable by car or by the shuttle bus, which will start at different hotels in Hameln (length of the trip about 15 minutes for those, who are not accommodated at Schlosshotel Münchhausen ‐ see below).

The Weser Uplands (German: Weserbergland) is a hill region in Germany (Lower Saxony, Hessen and North Rhine‐Westphalia, between Hannoversch Münden and Porta Westfalica near the river Weser). The tales of the Brothers Grimm are set in the Weser Uplands, and it has many renaissance buildings, exhibiting a peculiar regional style, the so‐called Weser Renaissance style. The region roughly coincides with the natural region of the Lower Saxon Hills defined by the Federal Agency for Nature Conservation BfN.
