Petriolo Hot Springs in Tuscany – Are They Worth a Visit?

Are you trying to decide if you should visit the Petriolo hot springs (aka Bagni di Petriolo) while you’re driving around Tuscany?

Maybe you’ve just visited Saturnia’s hot springs and want to more hot, sulphurous water in your life.

Petriolo has one of Tuscany’s warmest hot springs (water flows at 40-43° C, compared to Saturnia’s 37.5°C water temperature).

It’s small pools are layered and you can combine your soak with dip in the river’s cold water.

I recently visited the Petriolo hot springs on a Tuscany road trip with my husband and we were happy to stop for a quick visit on our way to Saturnia.

Fun Fact:  While you’re soaking in the Petriolo hot springs, you can look up and see Roman walls – these hot springs were fortified during Roman times.

Are Petriolo’s hot springs worth a visit? Yes and No.

YES, if:

  • You happen to be driving by.  But don’t drive out of your way.  There are other hot springs that are more worthy, and the parking can be a huge pain. 
  • You love hot (vs warm) springs. Petriolo’s hot springs are some of the warmest ones in Tuscany.
  • You want to alternate hot and cold soaks.  At Petriolo, you can soak in the hot springs and then walk down and sit in the chilly river.    

NO, if:

  • You’re looking for a luxurious, photogenic hot springs experience.  Petriolo’s hot springs are not fancy – you can see the pipes, there can be construction equipment and neon tape or fencing set up – you’ll need to plan your ‘perfect photo’ versus just snapping away.
  • You need easy access to bathrooms, restaurants, and parking.  There aren’t many services available in Petriolo. 
  • The smell of sulphur bothers you.  I think these are some of Tuscany’s smelliest hot springs.
  • You’re planning on visiting on a weekend in the summer.  The Petriolo hot springs are small and get to be very crowded on weekends in the summer (peak season for the springs).
  • This would be your one hot springs experience in Tuscany. There are other more memorable hot springs in Tuscany.

Cycling to Petriolo Hot Springs

You must love hills to bike here, but if you do, it’s an excellent place for (road) riding.  The small roads are quiet and the views are gorgeous.  You could visit as part of a multi-day trip in southern Tuscany or even as a day trip from nearby places like Siena or the Val d’Orcia.

Helpful Tip:  Make sure you have plenty of spare tires and equipment with you – there aren’t many bicycle shops in the area so you need to be self-sufficient.

Helpful Tip:  Have a bike lock with you and make sure you can see your bicycle(s) while you’re soaking. 

Getting to Petriolo Hot Springs with a Private Driver

Don’t feel like driving in Italy but want to do a ‘giro dei bagni’ – hot springs tour?  Hire a private driver (NCC – noleggio con conducente) and make your way to Tuscany’s best hot springs. LINK

Good To Know:  You can’t reach Petriolo’s hot springs by train.

Parking at the Petriolo Hot Springs

Parking in Petriolo is quite tricky.  There aren’t many spaces, and RVs tend to take up many of them.  The road also narrows before and after the springs, so you can’t just park anywhere along the road.

Helpful Tip:  Make sure you park in the designated spots, and if you park parallel along the road, stay within the lines.  The local police give fines. 

Don’t leave valuables in your car.  There are surveillance cameras in the parking area but theft still happens, including from cars parked along the side of the road.

Helpful Tip:  Look carefully as you pull into the main parking area – in some places, there is a small drop off and you’ll dent the front of your car if you try to park there.

Tips for Visiting the Petriolo Hot Springs

  • Bring your own water.  There is a small food truck on the road next to the hot springs, but if you want to bring your own water supply, you can pick it up at a grocery store on the way.  There’s a small Coop grocery store in nearby Monticiano.
  • Don’t visit on a summer weekend.  The Petriolo hot springs are small, and the summer weekend crowds will fill the pools up.  It’s better to visit during a weekday or outside of the summer season.
  • Don’t leave valuables inside your car.  Break-ins happen at Petriolo’s hot springs.
  • Hungry?  Order a schiacciata at La Locanda di Petriolo’s Bistrot.  You can sit indoors or at an outdoor shaded table.  Or, if you want to eat at the springs, you can buy a panino from the small yellow food truck on the road next to the springs. 
  • Change into your bathing suit before you arrive.  You won’t want to change in your car at Petriolo because there’s no privacy – the parking is all on the street and there are always people walking by.  It’s easier to change in your hotel or change in your car before you get to the hot springs.

Petriolo Hot Springs with Kids

Again, I wouldn’t go out of my way to visit Petriolo with kids, but it can make for a pleasant quick stop if you’re in the area outside the springs’ peak season (summer, especially weekends).  Helpful things to know for a visit with kids:

  • You need to walk down a dirt path to get to the hot springs.  It’s not stroller-friendly, so leave your stroller in your car.
  • There aren’t any toilets at the hot springs, but you can purchase something and use the toilet at La Locanda di Petriolo’s Bistrot just up the road from the springs.
  • The baths are small and shallow, which makes them easy to sit in with kids.  Plus, the river is fun for little ones (I’d argue, even more fun!).
  • Prep your kids for the sulphur smell.  Explain what it is so they won’t be shocked when they get their first whiff of ‘rotten eggs.’
  • Put your baby in a swim diaper.
