  • This old washhouse with turquoise waters located in Thunder will surprise you with its beauty. You'll be amazed really worth a visit. For the anecdote, the team Cousteau surveyed this water hole without reaching the end and have rebrousse of path without knowing how far it went down. The Enigma remains even today. A must-see like the rest of the old town which is very pretty.

  • Nice place. And the place is not very crowded, it is very quiet and relaxing. The pit is very impressive

  • A source is transformed into a large wash house beautifully decorated with flowers in the summer. It is impressive by its flow (300 litres per second?) and its turquoise color.
