We didn't really have a plan for our time there so we just wandered around the centre in the evening. Catania is full of gorgeous baroque architecture so we weren't short on things to see.
The main site I wanted to see was the Duomo (the outside is pictured above). It's been rebuilt throughout history due to facing earthquakes and eruptions but what stands today is pretty impressive.
- We were approached by several people asking us if we needed a taxi. However, the cabs they drove were all unmarked so we decided not to find out what would happen if we hopped into one. To stay safe/not get ripped off, look out for the taxis with 'taxi' signs on top of them and official logos on the side. There are a couple of taxi ranks around the city including one right outside Catania Centrale Station.
- There's no train to and from the airport, so you can either take an Ali Express bus or a taxi. You can find both at the central station, along with several other places.
- Buses are a great cheap way to get around Sicily if you plan on seeing multiple places. Catania's bus station is a giant car park round the corner from Catania Centrale Station with buses going to many different destinations. Tickets for the buses can be purchased at a ticket office close by on Via D'Amico 181.
