Thermal water rich in sulphates and fluorides and with a temperature of approx 60°C, gushes forth from the springs of Ai-Ais. In the Nama language, "Ai-Ais" means "burning water".
The thermal bath next to the hot spring is a popular recreation resort, especially during the winter months. The water is particularly soothing for people suffering from rheumatism. Of course, healthy people enjoy the spouting water fountains as well. There are indoor pools with various water temperatures and an outdoor pool.
