The town of Burgdorf is also called the door to the Emmen Vally. The river flowing past Burgdorf is called the Emme.

Four prominent and unique sandstone hills are facing the town across the river. They look like cut through the middle and are called the Gysnau Hills. The altitude to the top of them is just about 120m up from the Emme river. The round trip hiking up and along the top ridge of the four hills takes just about one hour.

The medieval town was mostly built from sandstone cut from queries from those hills.

Along those four hills rank some beautiful stories. One sad story claims that about 200 years ago a big boulder tumbled down unto a young couple in love burying them forever. The boulder is mysteriously sitting at the foot of the fourth hill.
