The Valletta peninsula is only a couple of kilometres in length and so the ideal way is to do everything on foot also allowing one to make use of the atmospheric stairs throughout this steep city. However, the city is built on a ridge, and is steep in parts requiring walking up and down stairs in some places, which can be tiring. The alternative would be doing it by car which is not ideal for visitors due to lack of parking space, direction signs and the fact that the streets are very narrow, often one way and confusing if unfamiliar. Most of the main tourist attractions are along the main street Triq ir-Republika which does not involve steep hills.
To get further historical information about the numerous places of interest through Valletta it can be useful to hire an audio guide. It is available in different languages Maltese, English, Italian, French, Dutch, German and Spanish from the Archeology Museum in Republic Street. You can choose independently from the 24 stops and it is not necessary to follow the given order. Stops can easily be skipped or visited in another sequence when tired or full of the new information.
Another possibility is to rent one of the horsecarts Karozzin, but be sure to haggle over the price.
