Lázně Toušeň is located about 14 kilometres (9 mi) northeast of Prague.

It lies in a flat agricultural landscape in the Central Elbe Table within the Polabí lowland.

In the western part of the municipal territory are two artificial lakes created by flooding sandstone quarries: Mezi mosty and Malvíny.

In 1777, part of the market town's land was separated and the new village of Káraný was founded on it.

After the World War II, the spa focused on the treatment of top athletes.
