Kundratice Spa originated as a part of the town of Osečná in 1881, and is one of the oldest spas in Bohemia.
Peat with a high iron and sulphur content is used here as a natural curative resource.

The location of the spa means that it has the favourable climatic conditions of the Ještěd range that protects the Kundratice Spa from the cold north-east wind. The countryside around the spa is rich in pine forests, groves, meadows and ponds.
