This is an outdoor bathing area at the foot of a fully restored old wooden mill (a watermill), from which it takes its name (muíño is the Galician word for «mill»).

It is part of the Thermal Walk of the city of Ourense, and it is located practically on the bed of the Miño River. It is surrounded by a large recreational green area that merges with the riverside vegetation of the place.

The complex consists of five pools: a main pool of 200 m2, a second one of 130 m2, and two smaller ones of 55 and 45 m2, as well as a cold water pool for contrast baths.

The bathing area has changing rooms with lockers and toilets available for users. Access is free, although there is a limited capacity.
