Cardiff Bay is the largest waterfront development in Europe (at time of writing), but there is a whole lot more to this than financial renovation and modern ideas. This is an attraction within an attraction, a true centre full of smashing bars, restaurants and cafes, not to mention plenty of points of interest. The Wales Millennium Centre, the Senedd, Pierhead, Norwegian Church and more are located here, making Cardiff Bay a full day out in itself. There are also plenty of water-based activities available, from sailing to rafting with plenty in between.
