Witzhave is a part of the Amt Trittau collective municipality within the district of Stormarn and lies roughly 20 km east of Hamburg.

The municipality borders the Sachsenwald to the east and has three rivers lowing through its territory - The Corbek, Witzhaver Au, Hahnenbek and the Bille.

[2] Witzhave is reachable via road or public transport through the 333 bus line of the HVV, connecting the municipality directly to Hamburg.

Witzhave was a prominent stop in the trading route between Hamburg and Lübeck with heavy freight wagons pulled by four to six horses frequently passing through the sandy road of the village.

The Bundesautobahn 24, running through the municipality, started construction in 1938 but was put on hold until December 1978 due to World War 2 and the division of Germany.

[2][4] Witzhave came to national attention in late February 1996 when two members of the far-left terrorist group Anti-Imperialist Cell (Antiimperialistische Zelle) were stopped and arrested on the main road leading through the village (Möllner Landstraße).
