A historical establishment which has its main building's architecture as its highlight, with large observation points, where the bath galleries are located. Throughout 2007 the Balneary has been under extensive renovation works, including its accommodation and thermal facilities, which have converted them into modern and comfortable facilities that kept their original architecture. A beautiful gardened area surrounds the establishment, where one will also find a mineral-therapeutic water pool, a perfect complement for treatments.

Location: near the Umia's riverbed that passes by Caldas de Reis, flowing towards the Atlantic. Another advantage of Caldas is its location, 12 Km. from Vilagarcía de Arousa, 21 Km. from Pontevedra, 36 Km. from Santiago de Compostela and 50 Km. from Vigo.
