Bathing season

Yes - I did open this years bathing season yesterday! As Käthy was dropping of her brother and his wife at the airport we thought that we could enjoy the brilliant day out in the sun. And so we did ... swimming for the first time this season. Käthy took me to an open air pool just a little outside Vienna. Refreshing water and sandy beach! It was great. Below see a picture of the sandy beach - and if you can guess where we were I will invite you for ice cream there!

Just leave your answer as a post below. If nobody finds out where we were I will solve the puzzle within the next couple of days!
