Fiuggi is about 75km southeast of Rome, roughly 1.5 hours by car. From Rome, take the A1 motorway toward Naples, exit at Frosinone, then follow signs northeast to Fiuggi. The drive is straightforward and the last stretch through the hills is scenic.
There is no direct train. The closest useful station is Anagni-Fiuggi on the Rome–Cassino line, from where local buses run to Fiuggi Terme. Alternatively, take a train to Frosinone and connect by bus. Services are infrequent, so check schedules before you go. Most visitors come by car, which gives the flexibility to reach Fiuggi Città separately from the spa town below.
