Many fishing lakes are nearby, two of which are in Berumbur directly. The most famous lake is the Kiessee, used for bathing.

The place was first officially mentioned as Bherum Buer in 1552. Later names were Behrumsbuhr (1645) and Berumbuer (1730). In the name of this settlement, the Proto-Germanic root *būr- appears twice: in the defining word as an umlauted Old Frisian form bēre, in the base word as Middle Low German būr. The meaning is "farming community belonging to Berum".
