About Terme del Bagnaccio

The Terme del Bagnaccio are halfway between a free hot spring and a spa: they're not free, but they cost very little, and in return you get clean pools, careful management and a very pleasant rural setting. They are north of Viterbo, along the route of the Via Francigena, and are run by a private association that takes care of maintenance.

The water rises at about 63 °C and feeds several pools at different temperatures. According to the most detailed description we found, there are six pools, labelled B0 to B5: only one is cold and was recently restored, while the others are hot and are emptied and refilled every night with fresh water from the spring and the well. This daily change of water makes the Bagnaccio one of the best-kept options in the area.

There is an important rule for families: under-14s may only use pool B1, the large central pool. The others are reserved for people aged 14 and over. Next to the pools there is also an equipped camper van area, much appreciated by people travelling that way.

As for prices, the most detailed list we found gives about €8 on weekdays and €10 on other days, with a reduced rate for Via Francigena pilgrims and an annual pass; a visitor confirmed the €8 entry fee in May 2026. That's why the Bagnaccio is classified as "small fee" and "regulated". Before you go, it's worth checking current prices and opening times, which also change with the season.

If you're looking for an inexpensive thermal experience with a minimum of organisation, the Bagnaccio is an excellent choice. It combines easily with the nearby Piscine Carletti and Bullicame, which are free, and with a stroll around Viterbo's old town.

If you're travelling by camper van, the equipped area next to the pools lets you spend the night and make the most of the morning opening, when the pools have just been refilled. If you're travelling by car, you can combine the Bagnaccio with a visit to the villages of the Tuscia, such as Bagnoregio, Montefiascone and Lake Bolsena, all a short drive away.
