A guide to Italy's most spectacular thermal spas for a winter escape

Winter is a season of biting cold and icy colours, of freezing, dark mornings and landscapes that seem bare and silent.

For anyone in search of relaxation, the perfect escape is a visit to a traditional thermal spa. Used since ancient times to harness the benefits of heat, which stimulates microcirculation and supports the body's immune defences, these places have evolved into fully fledged wellness sanctuaries. Between a massage and a sauna, the body can regain its balance — or at least enjoy a much-needed break.

Italy is one of the European countries where thermal spas are not only exceptionally well equipped, but also spectacular places to visit and experience. Here are six destinations not to be missed.

Pré-Saint-Didier: a historic spa at the foot of Mont Blanc

In Pré-Saint-Didier, a picturesque village of around 940 inhabitants in the Valdigne area of the Aosta Valley, at the foot of Mont Blanc, visitors can unwind outdoors while surrounded by snow. The spa garden features three outdoor pools and saunas housed in wooden chalets, with panoramic windows overlooking the Mont Blanc massif.

The wellness circuit includes whirlpool baths, relaxation pools with underwater music, invigorating waterfalls and innovative thermal treatments. There are also themed saunas in wooden chalets, aromatic steam baths, a mud treatment area, chromotherapy and aromatherapy rooms, and panoramic relaxation lounges.

Expert therapists offer both relaxing and invigorating massages. Throughout the day, a wellness specialist guides guests through relaxation techniques and exercises, and offers body treatments, beauty masks and aromatic scrubs. Spa access must be booked in advance, either online or through the reservation service. Children under 14 are not admitted.

The natural springs of Pré-Saint-Didier emerge from a grotto at the foot of the Orrido waterfall, near the spa complex. The area's thermal waters were already known in Roman times, although their systematic use began in the mid-17th century, when the first visitors came here to “take the waters”.

The spa itself dates back to 1834, while the building that once housed the casino was completed in 1888. For more than 150 years, the thermal baths were among the Aosta Valley's leading attractions, welcoming distinguished guests and becoming a favourite holiday retreat of the Italian royal family.

Completely restored after more than 30 years of closure, the historic complex has regained its former splendour while preserving its original architectural character.

Andalo: a Nordic sauna retreat in the Dolomites

Mountain pine sauna, herbal sauna, chromotherapy sauna, Finnish sauna and infrared sauna. A Turkish bath, outdoor whirlpool, Kneipp circuit and dedicated relaxation areas. And when the bell rings, it's time for an Aufguss — a traditional sauna steam ritual — or a sound bath.

There is a place in Andalo, in Trentino-Alto Adige, where time seems to slow down and your breathing falls into rhythm with the mountains. It is AcquaIn, the wellness centre at Andalo Life: a day spa open to everyone and dedicated to the culture of holistic Nordic sauna bathing, conceived as a true refuge from everyday life.

Here, between the Brenta Dolomites and Adamello Brenta Nature Park, northern European traditions meet the deeper roots of wellbeing, creating an experience in which everyday worries can be left at the door. There are no large thermal pools, but rather a circuit of saunas offering different temperatures and humidity levels, designed for those seeking to escape the pace of daily life through heat and silence.

Swimwear is not permitted inside the wellness centre. Guests must use a towel or bathrobe. Online booking is required to secure admission.

Merano: alpine rituals, hay baths and Finnish saunas

Following the summer season, Terme Merano in Trentino-Alto Adige is now welcoming guests to its sauna area.

A range of treatments harnesses the benefits of deep heat, including massages with hot lava stones and traditional South Tyrolean mountain hay baths. These are particularly beneficial for people suffering from rheumatism and osteoarthritis, as they help improve blood circulation.

Aromatic oil massages offer further benefits: gently warming the oil enhances its muscle-relaxing effects while allowing the fragrances of the herbs to unfold. Massages scented with lotus, frangipani or jasmine, meanwhile, help clear the mind.

There are also numerous rituals designed for two, from the Sissi Bath to purifying South Tyrolean aromatic treatments in the Imperial Bath, as well as edelweiss, grape or salt whirlpool experiences. The infrared cabin is another option, helping to relax muscles, ease contractures and soothe pain.

The organic South Tyrolean hay sauna operates at temperatures between 45°C and 60°C and takes its inspiration from the traditional Tyrolean farmhouse. The South Tyrolean honey steam bath, meanwhile, is set at 45°C and recreates the atmosphere of a beehive. At the Passerstein steam bath, guests can watch the waters of the Passirio River flowing by, creating a particularly restorative experience.

Temperatures rise considerably in the outdoor Finnish sauna, which reaches 100°C and offers an extensive programme of Aufguss sessions, led by experienced sauna masters who guide guests through traditional steam infusions.

After the sauna, the cosy corners furnished with sofas and cushions in front of a crackling fire are the perfect place to bring the day to a close.

Lake Garda: a thermal oasis in a winter garden

The Garda Thermal Park at Villa dei Cedri is a 13-hectare natural spa in Colà di Lazise, just a few minutes from the shores of Lake Garda. Unlike conventional indoor thermal centres, this wellness destination unfolds in the open air, within a centuries-old park filled with majestic cedars and rare plants. The park features two large thermal lakes fed by underground aquifers at depths of up to 200 metres.

The winter garden is located close to the main thermal lake. The changing facilities include separate men's and women's areas, with private changing cubicles, communal spaces, showers, toilets and hairdryers.

The sauna circuit features two Finnish saunas, a bio-sauna, a large steam bath with chromotherapy and aromatherapy, and a further spacious bio-sauna located outdoors in the garden reserved for the wellness centre.

The spa is open to both hotel guests and external visitors. It occupies the former horse stables, built in the late 19th century and subsequently transformed into a modern wellness centre while retaining traces of the original architecture.

Upstairs, guests will find the relaxation area, a heated space featuring an atmospheric fireplace. During the winter months, sun loungers overlooking the thermal lake are also available.

Tuscany: a journey through three iconic thermal resorts

There is only one thing more relaxing than a weekend at a thermal resort: a weekend at three thermal resorts. In Tuscany, visitors can now experience the Wellness Tuscan Route, a new itinerary bringing together three of the region's iconic thermal resorts for the first time: Fonteverde, Grotta Giusti and Bagni di Pisa.

The six-night journey includes two nights at each property and is designed to introduce guests to three different approaches to wellbeing.

Fonteverde lies in the heart of Val d'Orcia, a Tuscan landscape inscribed on the UNESCO World Heritage List in 2004. Here, guests are encouraged to slow down through Eastern disciplines and Ayurvedic traditions.

Grotta Giusti is a historic 19th-century villa surrounded by the Tuscan countryside, famous for housing Europe's largest natural thermal cave. Its main attractions include the cave's distinctive microclimate, the underground thermal lake and the therapeutic properties of its waters. The programme also features a Spa Floating experience, a meditative practice performed in the waters of the underground lake.

Bagni di Pisa, meanwhile, focuses on nutrition and the central role of the microbiota in maintaining good health. Inside the historic thermal palace, once the summer residence of the Grand Duke of Tuscany, guests embark on a guided programme with a medical tutor, dietitian and chef, exploring the principles of a diet inspired by the Mediterranean tradition.

Bagno Vignoni: the restorative power of ancient waters

Still in Tuscany and the Val d'Orcia, close to the historic medieval village of Bagno Vignoni, renowned for its thermal springs, lies Adler Thermae.

The resort's hyperthermal, sulphate-alkaline-earthy waters emerge from a spring just a short distance away at approximately 50°C before being brought down to 36°C for use in the pools, which remain open all year round. These include indoor and outdoor thermal pools — particularly beneficial for bones, skin and joints — as well as a swimming pool.

For those seeking a more exclusive experience, there is a salt grotto featuring thermal water at 38°C, enriched with Dead Sea salts to purify the skin and stimulate circulation.

Heat helps support respiratory function, stimulate diuresis, relieve muscle tension and improve tissue oxygenation. Thanks to their dissolved mineral content, these waters are particularly suited to supporting bone and joint health and skin wellbeing. They may also help alleviate conditions such as osteoarthritis, extra-articular rheumatism, tendinitis, cellulite, venous circulation disorders and various gynaecological and dermatological conditions.

These beneficial properties were already appreciated centuries ago, attracting distinguished visitors such as Lorenzo the Magnificent and Saint Catherine of Siena, to name just two.
