In the picturesque Nalón Valley, just minutes from Oviedo, lies one of northern Spain’s most prestigious resorts. Here, the grandeur of history blends seamlessly with modern comfort and well-being, creating a unique atmosphere surrounded by unspoiled nature. Its architectural solutions, featuring expansive windows and a design inspired by the majesty of the Roman Pantheon, attract travelers and celebrities in search of tranquility and renewal.
Nestled among the Asturian mountains and forests, which seem to guard an ancient secret, is a place where water rises from deep underground at 40 degrees Celsius and serenity becomes almost tangible. Only those who cross its threshold discover the allure of Las Caldas Villa Termal—a true gem of wellness tourism. For centuries, people have come here seeking to heal their bodies and restore their inner balance.
Its story begins in the 18th century, when the first channels for the region’s therapeutic mineral waters were built. Around them rose the Royal Balneological Center of Las Caldas, a building designed by architect Manuel Reguera. Its vaulted halls and galleries still retain the charm of historic baths. Today, more than two centuries later, this refuge combines time-honored traditions with the highest standards of a modern thermal center.
A water haven and personalized attention
The modern complex spans over 40,000 square meters and is divided into three main zones: the historic Balneario Real, the Aquaxana center, and the Manantial area. The latter features an impressive cave with pools, where water and stone combine to create an almost magical atmosphere. Every element of the route is designed to enhance the therapeutic effect of the mesothermal waters, which are classified as oligometallic, calcium-magnesium bicarbonate. One of the most secluded areas is the Hall of Columns—a private section with a foot bath, tropical shower, Roman bath, jacuzzi, and contrast showers, intended for couples or small groups. Here, classical architecture and soft lighting heighten the sense of tranquility. Wellness programs include anti-stress treatments, relaxing massages, detox programs, and wraps with algae or essential oils. The spa menu also features bioenergetic therapies and hydrotherapy sessions, all individually tailored and supervised by specialists. This venue goes beyond conventional tourism, offering a sensory experience of deep renewal.
Traditions, luxury, and Asturian gastronomy
The property features two hotels: the five-star Blau Gran Hotel Las Caldas and the four-star Blau Hotel Las Caldas. Both offer hospitality where modern comfort blends with classical elegance. The grand hotel’s interior stands out with unique spaces such as the Hall of Mirrors, a former 19th-century ballroom, and an elegant breakfast room with panoramic valley views. Las Caldas has become a flagship destination for wellness travel in Asturias. Access to the Royal Balneological Center is available for guests over 16 years old and requires prior reservation. Standard opening hours are from 10:00 to 14:00 and from 17:00 to 21:00. During the low season, admission is 35 euros per person from Monday to Friday and 48 euros on weekends. In the high season, which covers major holidays and school breaks, the rate is set at 48 euros. Each session lasts no more than two hours and includes a towel and special footwear. Wearing a cap and swimsuit is mandatory.
A culinary highlight to conclude the experience
The experience is enhanced by a carefully curated gastronomic selection. Restaurants such as Scanda and Viator reinterpret Asturian culinary traditions with a modern twist, using local ingredients, while chef Raúl Galán offers menus that unite the flavors of the sea and the mountains. All this makes Las Caldas a comprehensive luxury destination, where water, history, and cuisine merge into a single sensory journey. Getting here from Oviedo is easy: the complex is just five kilometers from the city center. Traveling by car along the AS-322 road takes less than ten minutes. For those who prefer public transport, there are regular bus services. You can also reach it by taxi or even by bicycle along the scenic Senda Verde route.
