On the “Tour de l’Oisans et des Ecrins” GR54, for those who know it.

September is the month to go and take a plunge in the lovely, the one and only, dare I say it, the unique Lac de l’Eychaude. What’s the water like? Cool? Just right for the season. Average summer temperature of 5 degrees as they say on the signs of the Parc National des Ecrins.
