The Valletta Waterfront is a promenade which you can get to easily either from the Upper Barrakka Gardens by using the elevator facilities at a price of around 2 Euro (you would get a return ticket when you purchase one), or by walking through Valletta city center towards the sea, and keep walking to the direction of the Cruise and Ferry terminal. Funnily enough, although the area is known as Valletta Waterfront, it is located in Floriana.
One of the reasons I go to this area is the obvious fact that it is lovely, especially in the evenings for a pleasant walk by the sea. It is also frequented because of the fact that there are a variety of restaurants to go to for lunch, dinner, coffee or for a couple of drinks. Different cuisines such as Mediterranean, Italian and Chinese are available.
Plus how can you resist this view?

Going there is a must, I tell you!
