One of the great things about Malta is that it's a very small island, so you can easily get around without a car.
The public transport system is reliable and efficient, with buses and taxis readily available. And many of Malta's attractions are within walking distance of each other.
However, if you're planning to explore more of the island, or you're staying in a remote location, then hiring a car may be the best option. Car hire is readily available and relatively cheap, starting from around £20 per day.
