The Čert'ák water reservoir is a natural swimming pool with an area of 3.5 ha and is about 3.5 km from the town. In the summer, Cert'ák is a very popular recreational spot for the town's inhabitants and visitors. It is also used for sport fishing. Many protected fauna and flora live in Certak. There is also a refreshment area with sanitary facilities.

A new children's playground has also been built, complete with terrain slides, balance beams and a sandpit.
There is also a legend associated with the site. Ignác Riedel of Bludovice founded a small water mill in this remote location in the early 19th century, later known as the Devil's Mill.
