Overview

About Piscine Termali del Bagnaccio

Piscine Termali del Bagnaccio, Italy is an outdoor thermal park approximately 8 kilometres north of Viterbo in the Tuscia countryside of Lazio, set along the ancient Via Francigena pilgrimage route to Rome. Known since at least the Etruscan-Roman period and documented as a waypoint for medieval travellers, the site was formally developed as a managed park in 2016 and, after a bureaucratic closure of over three years from May 2022, reopened on 2 August 2025 under new management by Rise Srl under a sub-concession from the Comune di Viterbo, valid until December 2027.

The park has four outdoor sulphurous thermal pools at varying temperatures, from cooler wading pools to hotter soaking pools, all fed by a continuous flow of spring water drained and refilled nightly. The water is sulphurous with both hyperthermal and hypothermal springs. The Tuscia thermal zone around Viterbo is one of Italy's densest concentrations of hot springs, and Bagnaccio is among the most accessible and affordable in the area.

The setting is simple and unpretentious. Wooden changing cabins, toilets, a bar, a picnic area with tables, free parking, and WiFi are available. Sunbeds and parasols can be rented. The park is popular with pilgrims on the Via Francigena, who receive a discounted entry rate with credentials.

Location & Access

Getting to Piscine Termali del Bagnaccio

Piscine Termali del Bagnaccio is located on Strada Garinei, approximately 8 kilometres north of Viterbo. By car, take the Via Cassia (SS2) and turn onto Provincial Road 7 (SP7) at the large Eni service station; from Viterbo the turning is on the left shortly after a local supermarket; from Tuscany (north) turn right shortly after the Fiera di Viterbo complex. The park is signposted and a large free car park is at the entrance. The journey from Viterbo town centre takes approximately 10 minutes by car.

Public transport from Viterbo is limited. The urban bus network serves the Viterbo area but direct routes to the park are infrequent; a taxi from the city centre is the most practical option for those without a car. Viterbo is reached from Rome by the regional train from Roma Ostiense to Viterbo Porta Romana (approximately 2 hours) or by coach on the Cotral network. From Florence, Viterbo is about two hours by car via the A1 motorway.

The park sits on the route of the Via Francigena, one of Europe's historic pilgrimage roads, making it a natural stop for walkers heading to or from Rome. Pilgrims with valid pilgrim credentials receive a reduced entry rate. The Viterbo thermal area also contains the Bullicame free springs, Piscine Carletti, and Terme dei Papi within a few kilometres, making the area suitable for a full day of hot springs near Viterbo without moving far from the city.

Safety & Etiquette

Piscine Termali del Bagnaccio Safety Tips

Piscine Termali del Bagnaccio is a managed outdoor site with staff on site during opening hours. The pools contain naturally sulphurous water at varying temperatures; always test the temperature of any pool before entering, particularly in the hotter pools where water can reach up to 65 degrees Celsius at certain points. Move carefully when entering to avoid scalding. No lifeguard is stationed at the pools; visitors bathe at their own risk and should supervise children actively at all times.

The site produces natural sulphur gas emissions from the thermal springs. Individuals with respiratory sensitivity or cardiovascular conditions should seek medical advice before extended bathing. The strong sulphur smell is a normal feature of all Viterbo thermal sites; it is most intense close to the spring vents and diminishes with distance. Do not place your head underwater in the more active pools where gas is visibly bubbling. Shower thoroughly before and after bathing.

The park fills nightly with fresh spring water and is drained for cleaning each week, which maintains hygiene standards. Outside food and drinks are not permitted; a bar on site offers snacks and beverages. Free parking is available. The current management holds a concession from the Comune di Viterbo valid to December 2027. Check current opening hours and prices at bagnaccio.com, as seasonal adjustments may apply. Advance online booking is strongly recommended at weekends and during summer months to guarantee entry.
