Since thermal waters were discovered at the end of XVIII century, the spa of Zestoa has lodged thousands of persons who found health and rest in this corner of Gipuzkoa. The Spa has had better and worse moments, but the best of all was the 1920’s, when bathers from all around the world came here. In those years, the village of Zestoa was covered with hotels and summer time was a continuous party. Techniques to improve water virtues have been evolved over the years. Nowadays, after the remodelation of all the instalations, we can enjoy the thermal swimming pools, sauna, muds, jaccuzi... and of course, the pure, crystal-clear drinking water. Those instalations are not only reserved for customers, so every visitor can enjoy them with previous appointment.
