Adler Spa Resort Thermae

Overview

Nestled in the heart of the Val d'Orcia, a UNESCO World Heritage landscape of rolling hills, cypress-lined roads, and golden light, Adler Spa Resort Thermae draws on a natural treasure that has attracted visitors for millennia: the healing thermal waters of Bagno Vignoni. At 36°C, rich in bicarbonate, sulphate, and volcanic minerals, these waters flow through 1,000 square metres of indoor and outdoor pools, forming the centrepiece of a resort built around total restoration.

The ADLER Med centre brings a modern medical dimension to this ancient wellness tradition, with an in-house blood laboratory, a team of specialist doctors available around the clock, and personalised prevention programmes rooted in holistic medicine. Beyond the spa, the resort celebrates Tuscan life at its finest: a gourmet kitchen led by Chef Gaetano Vaccaro working with local seasonal ingredients, a candlelit travertine wine cellar, and a landscape that invites exploration by foot, bicycle, or simply from a sun-drenched terrace.

Rooms and suites are designed with light, natural materials, and warm colours, each with panoramic views over the Tuscan countryside. Whether you come for a weekend of thermal bathing, a week-long medical wellness programme, or a Tuscan gourmet escape, Adler Spa Resort Thermae wraps every experience in the gentle, weightless feeling the ADLER brand calls home.

What is the thermal wellness experience at Adler Spa Resort Thermae?

The resort's wellness philosophy is rooted in the healing properties of its 36°C thermal water, naturally rich in bicarbonate, sulphate, volcanic substances, and trace minerals with proven benefits for bones, skin, and joints. This ancient resource flows through 1,000 m² of indoor and outdoor pools, creating a continuous circuit of warmth, buoyancy, and mineral absorption.

The spa extends well beyond the thermal baths. A generous sauna world includes the Finnish Panoramica forest sauna with Tuscan hill views, an organic sauna set in the travertine lake, cleansing steam baths (Grotta del Filosofo and the brine-infused Salino), and the herbal caldarium Artemisia with aromatherapy. Over 40 highly trained doctors, therapists, and beauticians deliver a treatment menu spanning ADLER's own organic cosmetics line, Ayurvedic therapies, and classic European techniques.

The ADLER Med centre takes wellness into medical territory. An in-house blood laboratory, advanced diagnostic equipment, and specialist physicians available 24/7 support personalised health programmes covering detox, weight management, stress reduction, longevity, and sleep therapy. It is this integration of ancient thermal tradition with modern preventive medicine that sets the resort apart.

What do you eat during your stay at Adler Spa Resort Thermae?

Dining at Adler Thermae is a Tuscan journey led by Chef Gaetano Vaccaro, whose Mediterranean cuisine highlights the best local and seasonal produce. The day begins with a vast breakfast buffet featuring home-made baked goods, vitamin-packed juices, and regional specialities. At lunchtime, the cosy Osteria in the park serves light, fresh dishes.

Evenings bring multi-course gourmet dinners, from classic Bistecca alla Fiorentina to creative interpretations of Tuscan tradition. The romantic open-air restaurant and the candlelit travertine wine cellar offer memorable settings, while the piano bar provides a cheerful accompaniment. The cellar stocks selected Sicilian, Italian, and international wines alongside bottles from Tenuta Sanoner, ADLER's own biodynamic estate.

Guests on ADLER Med programmes receive personalised nutritional guidance. The all-inclusive arrangement covers culinary enjoyment throughout the day, from breakfast through afternoon snacks to dinner, ensuring that nourishment and pleasure are woven into every hour of your stay.

What are the facilities like at Adler Spa Resort Thermae?

The resort sits within a landscaped park in the Val d'Orcia, with architecture that blends into the Tuscan hillside. Guest rooms, Superior Rooms (35 m²) and Family Suites (2 bedrooms, 3-5 guests), feature natural wood floors, warm colours, balconies or terraces with panoramic views, walk-in rainfall showers, satellite TV, minibar, Wi-Fi, and a tea and coffee bar.

The thermal and spa complex includes 1,000 m² of 36°C thermal pools (indoor and outdoor with whirlpool features), a semi-Olympic 25-metre sports pool, a multi-sauna landscape (Finnish panorama sauna, organic sauna, steam baths, herbal caldarium), and extensive relaxation areas. The ADLER Med centre houses consultation rooms, a blood laboratory, and diagnostic facilities.

Activities include guided nature walks through the Val d'Orcia, cycling excursions to historic villages, yoga sessions (including sunrise yoga and yoga in thermal waters), cooking classes at the biodynamic Tenuta Sanoner farm, wine tastings in Montalcino, and cultural tours. The resort is open year-round and welcomes families, though there is no dedicated kids' club at this property.
