Mega Thermal Spa in Parc de la Mola, 10, Escaldes-Engordany, Andorra
Caldea Thermal Spa
Southern Europe's largest thermal spa complex at 6,000 square meters, rising 80 meters as Andorra's tallest building. Thermal lagoons, outdoor pools, saunas, and steam rooms fed by natural Pyrenean mineral waters, with the premium Inúu adults-only zone offering exclusive circuits and mountain views.
Caldea Thermal Spa is Southern Europe's largest thermal spa complex, occupying a striking modernist tower that rises 80 metres above Escaldes-Engordany and dominates the Andorran skyline. Designed by French architect Jean-Michel Ruols and opened in 1994, the building's glass-and-steel spire has become an architectural landmark of the Principality of Andorra. At its heart lies a vast 6,000-square-metre complex fed by natural geothermal mineral waters sourced from the Pyrenean mountain aquifer, maintained at temperatures between 32°C and 36°C.
The main thermal area features an indoor-outdoor lagoon, outdoor pools with jacuzzi jets, Roman baths, and a series of saunas, steam rooms, and Turkish hammams. Natural light floods the space through the glass atrium, framing panoramic views of the surrounding Pyrenean peaks. The mineral-rich waters are valued for their therapeutic benefits for circulation, muscle recovery, and stress relief, drawing visitors from across Europe year-round.
For those seeking a more exclusive experience, the adults-only Inúu premium circuit occupies the upper floors and offers floatation pools, a salt cave with halotherapy, chromotherapy cabins, an ice waterfall, and a relaxation gallery with direct mountain vistas. Access to Inúu is priced separately and recommended for visitors who want a quieter, more contemplative session away from the lively main lagoon.
Caldea's treatment menu encompasses massages ranging from traditional Pyrenean aromatherapy blends to hot stone techniques, as well as facial treatments, body wraps, and anti-ageing rituals. Therapists hold formal certification and the centre maintains partnerships with established European wellness product brands. Private treatment rooms are available, and couples' packages combining circuit access with a shared massage are a popular choice.
Reservations for treatments are strongly recommended, particularly on weekends and during the ski season from December to March, when demand from Grandvalira skiers increases significantly. Entry to the main thermal lagoon area can be purchased on a walk-in basis subject to capacity; however, advance online booking guarantees entry and often attracts promotional pricing. A restaurant and juice bar on-site allow guests to extend their visit without leaving the complex. Appropriate swimwear is required throughout; disposable slippers and a towel are available for hire at reception.

FAQ
What is the difference between standard Caldea access and the Inúu circuit?
Standard access covers the main 6,000 sq metre thermal lagoon, outdoor pools, saunas, and steam rooms. Inúu is a separate adults-only (18+) premium circuit on the upper floors featuring floatation pools, a salt cave, chromotherapy, and mountain-view relaxation areas, priced at a higher entry rate.
Do visitors need to book in advance?
Walk-in entry to the main lagoon is available subject to daily capacity. Treatments and Inúu access should be reserved in advance, especially on weekends and throughout the December-to-March ski season when the complex is at its busiest.
Is Caldea suitable for children?
Children are welcome in the main thermal lagoon area with accompanying adults. The Inúu premium circuit is strictly adults-only (18+). Minimum age restrictions may apply to certain treatments; check the treatment menu when booking.
How should visitors get to Caldea from central Andorra la Vella?
Caldea is located in Escaldes-Engordany, within comfortable walking distance of central Andorra la Vella. Regular bus services connect major Andorran towns, and taxis are readily available. A car park is adjacent to the complex for those arriving by road.
