Jonction is a place where rivers Rhône and Arve are joining each others, which creates a beautiful and unique natural phenomenon.
Both rivers have different colors of water and when joining, their waters are mixing and shuffling and joining together into the one final river, Rhône.
You can watch this scenario best from the bridge, situated conveniently just 40 meters after the jonction.
Southern River Arve is faster, more rapid and move the white sand, that's why it is almost milky white, while the northern river (coming from the Lake), Rhône, is slower and darker.
