Free hot springs in Sicily

Sicily owes its hot water to volcanoes. Etna is the most famous, but if you're looking for a free thermal soak the places to head for are elsewhere: the volcanic islands of Pantelleria and Vulcano, the valley of the Fiume Caldo near Segesta and the Madonie mountains, where a small rock pool collects sulphurous water at about 37 °C.

The list below shows all the Sicilian free hot springs we have checked, with the current status of each. Almost all are free and have no facilities: no changing rooms, no showers, often no shade. The exception is Vulcano's Pozza dei Fanghi, which now has an operator and an entry ticket.

Pantelleria, the island of free hot springs

If there's one place in Italy where thermal wellbeing is truly within everyone's reach, it's Pantelleria. In a couple of days, with a car or a scooter, you can try very different experiences:

• The Specchio di Venere, a turquoise volcanic lake with hot springs along its banks and natural mud on its southern shore.
• The Gadir pools, carved into the rock on the quay of a little harbour, with water between 39 and 50 °C and the sea a step away for cooling off.
• The Grotta di Sataria, a small sea cave with three pools at about 40 °C, linked to the legend of the nymph Calypso.
• The Bagno Asciutto di Benikulà, a natural cave sauna on Montagna Grande, where steam comes out of the rock at about 38 °C.
• The Nikà springs, in an isolated cove on the south coast, where hot water mixes with the sea.

The best time is from late spring to early autumn, avoiding the middle of the day in August. The Gadir pools and the Sataria cave are small: you'll enjoy them much more at sunset or out of season.

Vulcano: warm sea and mud

On Vulcano, reached by hydrofoil from Milazzo, the Spiaggia delle Acque Calde is public and free: bubbles of volcanic gas rise from the seabed and warm the sea near the shore. Next to it is the Pozza dei Fanghi, which reopened in April 2026 after a long closure and is now managed, with a small ticket. On an active volcanic island conditions can change: always respect the orders of the municipality of Lipari.

Segesta and the Madonie

On the mainland, the Polle del Crimiso are sulphurous pools along the Fiume Caldo, a few minutes from the Doric temple of Segesta: a perfect day of nature and archaeology. In the Madonie, the pool at Sclafani Bagni is reached by a scenic downhill path below the village.

Practical tips

• Water shoes: volcanic seabeds, rocks and mud are slippery.
• An old swimsuit: sulphur and mud stain and leave a smell for days.
• Drinking water and a hat: many Sicilian springs are in full sun, with no shade.
• Care with the heat: some springs exceed 50 °C; always test the water with your hand.
