The individual graduation towers are between 70 and 350 metres long and 9 metres high, embedded in a rocky valley, where thermal healing water trickles down from the 500-metre-deep spring and a fresh sea breeze blows with an evaporation area of 16,000 square metres in the Salinental valley.
From 1732 - 1998 salt for baths and foods was produced with the help of these salt waterfalls.
