Saturnia Hot Springs: Cascate del Mulino Tips, Parking & Opening Hours (2026)

Saturnia is quite simply the most beautiful and impressive thermal bath we’ve ever seen. Thousands of tourists make their way to this small town in the south of Tuscany every year for a relaxing soak in the hot spring and, of course, to take a few photos. The Cascate del Mulino – also known as Terme del Gorello – are truly Instagram-worthy and one of Tuscany’s most photogenic highlights. In this travel guide we tell you how to get there on your Italy road trip, what the difference between Cascate del Mulino and Saturnia is, and what to look out for when you visit.

Saturnia | The Cascate del Mulino Thermal Spring

First, a quick clarification: We’re describing the most famous thermal spring in Tuscany, located in the town of Saturnia. This spring is called the Cascate del Mulino.

Nearby there’s another thermal spring, but unlike the Cascate del Mulino, this one charges an entry fee: the Terme Di Saturnia. It’s a paid thermal bath and spa, completely separate from the free Cascate del Mulino.

Quick summary:

• Saturnia: The town where the thermal springs are located
• Terme Di Saturnia: Paid thermal spa in Saturnia
• Cascate del Mulino: Free natural thermal spring in Saturnia

Saturnia itself is far from ordinary – it’s considered one of the oldest towns on the entire Italian peninsula. According to legend, the Roman god Saturn himself lived here. The mystical aura of the place is no doubt enhanced by the hot sulphur spring, which has been bubbling up from the earth for over 3,000 years and drew the Etruscans and Romans here for cures and relaxation.

Since “Saturnia” has become the common name for the free Cascate del Mulino spring, we’ll continue to use the terms interchangeably. The name only matters when you’re navigating there – you’ll need to follow the right road signs. More on that in the Getting There section.

Cascate del Mulino

The Cascate del Mulino is a publicly accessible thermal spring fed by water at a constant 37°C. This sulphurous water originates from the slopes of the nearby Monte Amiata, where rainwater seeps down to depths of up to 200 metres and becomes enriched with sulphur.

Thirty kilometres later, the water emerges at the surface in Saturnia, and 800 litres per second spill over a small waterfall (hence the name Cascata – Italian for waterfall) into the Cascate del Mulino.

The spring looks so picturesque and perfect that you’d be forgiven for thinking it was man-made. But everything here is completely natural.

Over thousands of years, natural travertine terraces have formed – pools of warm mineral water you can bathe in today. The beautiful turquoise water isn’t just visually stunning; its high content of calcium, magnesium and sulphur is said to be very good for the skin.

The sulphurous water has also been credited with healing properties since antiquity – particularly for rheumatism, arthritis and metabolic conditions. Whether you believe that or not, after a few hours soaking in the warm, bubbling water you’ll feel completely rejuvenated. We can confirm that from personal experience.

We absolutely loved spending a few hours here, just soaking and switching off.

Warning: Small Red Worms in the Water

When you’re bathing in the pools, you’ll probably come across small red worms in the water. These are midge larvae that have made the hot springs their home – they like it warm too.

The worms may look a little off-putting at first, but they’re completely harmless and won’t bother you.

What to Pack for Saturnia

• Water shoes: The travertine pools are slippery and the riverbed is rocky in places. You’ll regret coming without them.
• Old swimwear: The sulphurous water leaves marks on light-coloured swimwear. Bring something older or darker.
• Towel & change of clothes: Changing facilities and showers are only available at the car park – there’s nothing at the spring itself.
• Snacks & water: There’s nothing to buy at the spring. The nearest bar is at the car park.

Getting to Saturnia – How to Find the Cascate del Mulino

If you’re arriving by hire car* or campervan, it’s important to follow the right signs. From a distance, follow signs for Saturnia.

As you get closer to the town, make sure to follow signs for Cascate del Mulino – not for Saturnia itself or the paid spa Terme di Saturnia. Otherwise you’ll end up in the wrong place.

You’ll find the paid car park here on Google Maps.

Tips for Visiting Saturnia

Changing Facilities & Toilets

Because the Cascate del Mulino is completely free, there are no facilities at the spring itself – no changing rooms and no toilets. You’ll need to change using a towel for modesty and use the facilities at the car park.

Best Time to Visit Saturnia – When is it Worth Going?

Because the spring is free with no fixed opening hours, you can visit any time of year. We think it’s most magical when there’s a strong contrast between the warm water and the cool air – we visited in early November and loved every minute.

In summer, when temperatures can easily hit 30°C, that contrast disappears. Still enjoyable, but also much busier than in the off-season.

Whatever time of year you visit, aim to arrive early in the morning or in the evening – that’s when you have the best chance of some peace and quiet.

Tips for a More Peaceful Visit

You’ll never have the Cascate del Mulino entirely to yourself – unless you come in the middle of the night. But there is a little insider tip if you’d like some space: follow the spring a few metres back towards the road.

There the water flows in a roughly one-metre-wide stream towards the waterfall, and you can bathe just as well there – with a bit of luck, almost alone. You’ll find the spot here on Google Maps.

One more secret tip: visit the Cascate del Mulino at night during a full moon. You’ll have the place almost to yourself, the steam rising over the warm water looks absolutely magical in the moonlight, and the atmosphere is indescribable. Bring a torch – there’s no lighting on site whatsoever.

Parking in Saturnia – Cars, Motorbikes & Campervans

There’s a large paid car park just 200 metres from the entrance to the spring. You can park all day at €2.50 per hour, and the car park is supervised.

Important: Only cars and motorbikes are permitted in this car park – campervans and motorhomes are not allowed.

If you’re travelling by campervan or motorhome, finding a spot will be a challenge. There are no other official parking options along the road before or after the spring. You’ll find a few informal spots via the Park4Night app.

If you need an official pitch, there’s a campsite about 2km from the spring from €16/day. You can also park for just 4 hours for €8. Find the campsite here on Google Maps.
