Bad Langensalza is located in the Thuringian Basin, the fertile lowlands along the Unstrut river. The river Salza flows through the town and joins the Unstrut about 2 kilometres east of the town. Bad Langensalza lies in an unwooded, intensively farmed and largely flat landscape that rises to the west to the Hainich, to the north to the Heilinger Höhen and to the southeast to the Fahner Höhen. Due to this location, the climate in Bad Langensalza is relatively mild and, with annual precipitation of about 500 millimetres, very dry.
