The source intermittente
A geyser in the heart of Ardèche
As incredible as it seems, a real geyser naturally springs up 4 times a day, in the heart of Vals-les-Bains. Every six hours, a spring can be observed to slowly emerge from the ground, then transform into a jet more or less powerful depending on the day. La source intermittente attests to the extraordinary richness of the subsoil activity in Vals-les-Bains.
A rare natural phenomenon
This natural phenomenon is the interaction of several elements: a gas tank that pressurizes the water, and a water tank.
The power of the jet varies from day to day and sometimes the water column can exceed 15 metres ! With each spurt, nearly 800 litres of water come out of the earth. A rare natural process that surprises many spectators gathered around the Intermittent Source every day.
The Intermittent Source springs up every 6 hours.
