The capital city of Malta, Valletta, is located on a headland facing the Mediterranean sea North and south of it are harbors and important cities can be found on the land behind. In the north it is Sliema and St. Julians that are modern cities with lots of hotels. In the south the Three Cities Cospicua, Senglea and Vittoriosa can be found with their ancient city structures. Maybe you choose a hotel in these areas, for sure you want to visit them and best to do so is taking one of the ferry boats.
In the north the ferry harbor can be found at the promenade of Sliema, close to the shopping street (Triq Bisazza). Dependent on the season the ferry operates between 7 am and midnight or at least until 7:30 pm in winter. In Valletta, the ship anchors north of the city at Triq Il-Lanca. There you’ll have to walk up the mountain.
That’s a different if you choose to go from Valletta to the Three Cities. At the Upper Barraka Gardens there is now a lift bringing you down to the water or most important: up afterwards without climbing the hill. The lift is included in your ferry boat ticket. The ferry than passes along yachting marinas between Senglea and Cospicua and ends close to the end of the harbor arm.
For both routes you can buy tickets when boarding the ferry boats. The ferries have inner and outer areas so that you can decide if you want to have good views on the harbor or relax inside.
