Finding somewhere a little remote is the trick, place can get crowded, that's why I avoid august.
May, June, Juli are ok and september is even nicer cause off the water temp.
I visit the place sometimes two times a year and do the 11 hour drive from holland and had allmost the same Colas,
went for a beer in a small bar near Guethary , standing there, some French guys playing cards and than, from behind someone from your hometown is asking, wanna beer ?
damn the world is smal
