About Terme dei Papi
Terme dei Papi, Italy is the oldest and largest thermal spa in Viterbo, situated approximately 4 kilometres west of the city centre on Strada Bagni. Known since Etruscan and Roman times, the site gained its name in 1450 when Pope Nicholas V commissioned a palace so he could stay during treatment courses. Dante Alighieri mentioned the Bullicame spring in the Divina Commedia. The modern facility opened in 1993 after extensive renovation.
The centrepiece is the Monumental Pool, over 2,000 square metres fed by the Bullicame spring at a constant 34 degrees Celsius. The Natural Grotto is a cave where thermal water cascades at 58 degrees, filling it with sulphurous steam beneficial for skin, respiratory, and joint conditions. Medical treatments include inhalation, mud therapy, balneotherapy, and grotto therapy. The facility holds NHS Super First Category accreditation.
The 4-star Hotel Niccolo V is on the grounds, giving guests early pool access from 8:00. A daily visitor cap of 1,200 is imposed by the regional concession; advance online booking is strongly recommended.

Safety & Etiquette
Terme dei Papi Safety Tips
Terme dei Papi is a professionally managed facility with trained staff, medical personnel for therapeutic treatments, and NHS accreditation. The monumental pool is maintained at 34 degrees Celsius, a comfortable temperature for most healthy adults and for children under appropriate supervision. Those with cardiovascular conditions, low blood pressure, skin disorders, or other health concerns should check with the facility's medical team or their own doctor before using the pool or grotto. Pregnant women should seek medical advice before thermal bathing.
The Natural Grotto operates at high temperature and humidity. The water inside cascades at 58 degrees Celsius and the cave fills with sulphurous steam. The session duration inside the grotto should follow the guidance of facility staff. Exit if dizziness, nausea, or breathing difficulty occurs. The grotto is typically a one-time entry included in certain packages; confirm access arrangements before your visit as entry is managed to control capacity.
Swimwear and shower caps are required in the pool area. Robes can be rented and are practical given the distance between changing rooms and pool facilities. Do not wear silver jewellery; the sulphurous water can discolour it. The monumental pool is closed on Tuesdays for routine maintenance; on holidays falling on a Tuesday, the closure may shift to Wednesday. A Saturday night session is available from 21:00 to 01:00 at 20 euros per person. Always book online in advance, as the daily 1,200-person limit can be reached early on busy days.
