The Metro Valencia consists of ten lines (from which four are a tramway) and connects the suburbs with the city. On 2023, the one-way fare for one zone is €1.50. The card tself costs an additional €1 (pasteboard) or €2 (plastic) and contains a rechargeable chip. This metro system is not extensive, but can get you to major points within the city. If you want to take the tram, you have to buy a ticket from the machine, then validate it, before you get on.
If you use the metro a lot, you should consider getting a Bonometro, or a one, two- or three-day pass, which can be quite economical. For just over 12€, you can ride for 72 hours on the metro and tram as much as you like during that time; a bonus is that if you buy a ticket at, for instance, 16:00 on a Monday, it will expire not on Wednesday night, but on 16:00 Thursday.
