MUST MUST MUST book as long in advance as possible (20Euro)!!! We visited off-season so we were lucky enough to be able to purchase tickets (25Euro) in the morning in the Museum of Archaeology in Valletta (had to walk around a bit to find this one too). Then took a bus to Paola, bus driver showed us where to get off, though there were no visible signs, so we asked the neighbors as it's located in the midst of a residential neighborhood. An amazing site to visit! From there a 5-10 min. walk to Tarxien temples excavation site, another real nice site to visit (as long as you appreciate and are interested in archeology) - 5-6Euros. From there a 10minute bus ride (from the PRISON station) to Vittoriosa (=Birgu) where we visited the Maritime Museum and The Inquisitor's Palace (an interesting experience of a "museum" in the old palace/prison).
