JMF,
Did you not try to swim in the little Lac du Lauzon? I would have.
How similar Brittany seems to the south west of England in the Belle Ile en Mer blog. I suppose it should - it was probably part of the same land mass at one time.
It is fantastic and wonderful that the naturist hikers mixed freely with the textile hikers. Did any of the textiles take off their clothes and become naked hikers?
How many were in your party?
