The transport system in Malta is small but extensive, and the islands’ domestic system of public transport is reliant mainly on buses and taxis, although there were both a railway and a tramway in the past.
Buses are the primary method of public transport for the Maltese Islands and have been in operation there since 1905, offering a cheap and frequent service to many parts of Malta and Gozo. The vast majority of buses on Malta depart from a terminus in Valletta. Malta’s buses carried over 40 million passengers in 2015

There is also a ferry terminal at the Grand Harbour that connects Malta to Pozzallo and Catania in Sicily.
