Luxembourg in August

My mother and her partner were visiting from Australia to start a European river cruise from Amsterdam. So we popped over from the UK to see them. Afterwards, we got on another train, and were in Luxembourg a few hours later. We discovered a fairy tale city that is one of the jewels of Europe. We also took day trips to Vianden Castle - one of the world's prettiest - and to the famous Mullerthal trail, for some hiking.
