In the lush valley south of Oviedo, the historic thermal town of Las Caldas has drawn visitors to its mineral waters since Roman times. The modern Blau Gran Hotel sits within the wider Las Caldas thermal complex — centred around the 18th-century Royal Spa building, where officially recognised mineral-medicinal waters still shape the experience. This is a traditional thermal spa stay, built around hydrotherapy, structured programmes and the European ritual of “taking the waters,” with days spent moving between pools, steam, contrast and rest.

BackWhat we love
Blau Gran Hotel Las Caldas
Water leads everything here. The thermal complex is extensive, centred around the historic Royal Spa and the Aquaxana centre, where indoor and outdoor mineral pools form the core of the experience. The approach is traditional in the best sense — moving between temperatures, resting, then repeating. It’s not about pampering; it’s about proper recovery. Over time, the rhythm works, easing tension in a way that feels both credible and lasting.

Thermal ritual
Mineral-medicinal waters
Las Caldas’ waters are officially classified as mineral-medicinal and have long been used for muscular, respiratory and stress-related conditions. The hydrotherapy circuit moves through immersion pools, contrast baths, steam rooms and rest areas, designed to be followed in sequence — warm, cool, rest, repeat.
Programmes
Structured restoration
Multi-day programmes focus on stress reduction, sleep, detox or physical recovery. Hydrotherapy sits at the centre, supported by massage, physiotherapy and wellness consultations. The approach is structured and repeatable, with water as the main tool for change. Over time, the rhythm builds and the body begins to recalibrate.
Table
Asturian produce, light and fresh
Dining reflects Asturias’ regional produce — seafood, seasonal vegetables and local cheeses. The style is light and balanced, in keeping with the pace of a thermal stay. Meals feel simple and well judged, designed to support rather than interrupt the rhythm of time in the waters.
Place
Asturias’ green valley
Asturias feels distinctly different from Mediterranean Spain — greener, cooler and shaped by Atlantic air. Las Caldas sits in a quiet valley along the Nalón River, surrounded by wooded slopes and countryside trails just beyond Oviedo. You can explore the area on foot or by bike, with guided routes available, and the landscape stays lush and green throughout the year.
Sleep
Rooms
Rooms in the Blau Gran Hotel are contemporary and spacious, designed for comfort between time spent in the thermal pools and relaxation areas. Interiors are calm and neutral. Evenings in the valley are quiet, and sleep comes easily.

Asturias Airport is around 45–50 minutes by car. Oviedo is just 10 minutes away, making the hotel easy to reach by taxi or transfer, though a car allows for exploring the surrounding countryside.

Things to do
Time here centres around the thermal experience — moving between pools, treatments and rest. Beyond the spa, you can explore the surrounding valley on foot or by bike, with guided cycling routes available. Oviedo offers culture, historic streets and local dining, while the Asturian coastline can be reached for day trips.

Points of interest
Oviedo is a short drive away, known for its old town, cathedral and traditional cider houses. The Nalón River valley offers quiet walking and cycling routes, while the wider Asturias region is known for its green landscapes and Atlantic coastline.
Sustainability
The use of naturally occurring mineral-medicinal waters sits at the core of the hotel’s offering, drawing on a long-standing tradition of low-impact, resource-based wellness. The surrounding landscape remains largely unspoilt.
