The cities of Florence and Verona are connected by Italian high-speed railways, so traveling by train is the fastest, cheapest and most comfortable option. The distance from Florence to Verona is 230 kilometers.
By train
High-speed trains from Florence leave from the Santa Maria Novella station, and in Verona from the Port Nuova station (Verona Porta Nuova).
I recommend, whenever possible, to always use Italotreno trains that depart from Florence to Verona 4 times a day. When booking in advance, tickets in economy class cost from 14.90 euros. It is very convenient to leave Florence, for example, at 08:54 in the morning, then you will arrive in Verona at 10:24.
In Verona, you can spend a rich and interesting day by ordering individual excursions.
You can return from Verona to Florence at 19:44, leaving the evening train at 18:17.
Similarly, you can plan your trip from Verona to Florence. It is convenient to leave Verona at 08:17 in the morning, so that at 09:44 you will already be in Florence, where you can spend at least one perfect day, or better all three.
You can also get from Florence to Verona by Trenitalia high-speed trains, but their site is terribly inconvenient, constantly buggy, and most of the prices are higher.
By bus
The option to get by bus from Florence to Verona can be advised only by true fans of this kind of travel. Travel time will be from 2 hours 40 minutes. The cost of day tickets starts at 14 euros - with timely planning of cultural rest for about the same price, you can travel by train.
Of the comfortable options in Italy, I advise Flixbus buses that depart from Villa Constanza or Piazzale Mintelungo stations.
Buses arrive in Verona at the parking lot at Port Nuova Station.
By car
Getting from Florence to Verona by car makes sense if you plan to spend at least a few days traveling and visit the little fabulous towns along the way. Between the major cities of Italy, due to parking problems and restrictions on access to the historic center, I recommend traveling only on high-speed trains.
