Valletta the small capital city of Malta, Capital of Culture 2018, ist stunning at any time, is recognised as a site of historic importance, has more than 320 monuments. You can easily explore all the attractions on a short walk.
Malta in the Mediterranean Sea is a wonderful island full of beautiful beaches, impressive architecture and delicious food.
From Sliema to Valletta you can take the ferry has a good connection, so you don't have to take the bus around the outside of Valletta, this way is shorter.
