As you enter Carvalhelhos, an access on the right takes you to the Caldas Santas springs, whose waters are indicated for the treatment of dermatological, kidney, intestinal and liver problems.
You can try the thermal water during the bathing season.
Legend has it that a harvester with sores on her legs was mowing grass in a slough in Carvalhelhos covered by water that flowed from two springs. During the days of mowing, she noticed that the wounds closed up and finally disappeared. Word quickly spread and many people flocked to the place to try the water to treat a variety of illnesses.

Take a leisurely stroll through the park, which is lined with lush vegetation and cut by a water line. You can try the thermal water during the bathing season. The inn and spa are closed.
