Valh d’Aran (Pirineos)
December – March


Tredós is the last town of Naut Aran (before reaching Baqueira). It is located 1,348 m above sea level, at the entrance of Aigüestortes & Sant Maurici National Park. This is the ideal starting point to discover and explore the trails, valleys, peaks and hills that bring us to the more than 30 mountain lakes that adorn further  Colomèrs Mountain Range, with granite peaks that almost reach 3,000 m. and give to this valley called Aiguamog an incomparable beauty.


Our route with snowshoes, skis & pulka or snowmobiles, will take us, overcoming the riverside of Aiguamog to the magnificent thermal baths of Tredòs (1.740 m), the sulfurous waters of which have already enjoyed the Romans. These ancient baths were recovered in 1988. This place can breathe peace and tranquility.

Tredòs has a rich historical and cultural heritage. Church of Romanesque style, Santa Maria del Cap de Tredòs, dates back to the XI-XIII centuries and has two features that make it unusual: the presence of a crypt under the altar and the location of the tower away from the body of the religious building .



The hotel – Banhs of Tredòs and its hot springs:


The hotel – Spa, located half way up the valley,  due to its location, is without doubt spectacular.

The exterior spa circuit approaches the thermal spring water and is covered with a glass dome that keeps the interior temperature pleasant throughout the year. It has a natural pool of sulphurous thermal water, Finnish sauna and jacuzzi.


The millenary drop

Unlike the non-thermal springs, the time when the water is traveling through the earth’s crust is very long, even thousands of years. The waters issued today, fell from the sky many centuries ago. The sulphurous water comes from a spring with more than 5000l / h flow. and at a temperature of 33 ° C. (Sulfur gr.de 0.028 per litre, smelling hydrogen sulphide and sulfur ions, sodium, potassium, calcium and chlorine. Residue solid 0.6 g / l rich in sulfobacteries).
