Balneario de Trillo Guadalajara

Balneario de Trillo, on the banks of the Tajo river in the Alcarria region of Guadalajara province, Castile-La Mancha, draws on sulfurous springs in one of Spain's most historically documented thermal venues — the baths here have served travellers since at least the 16th century, and the surrounding Alcarria landscape of river gorges, lavender fields, and medieval fortifications was immortalised by Nobel laureate Camilo José Cela in his celebrated travel memoir 'Journey to the Alcarria' (1948). The naturally warm sulfurous waters supply wellness pools in a spa setting that preserves the traditional balneario atmosphere. The Tajo river valley at Trillo, with its dramatic canyon sections and the reservoir formed by the Entrepeñas and Buendía dams — now part of Spain's famous 'Sea of Castile' sailing waters — provides a scenic and historic Castilian context for this traditional central Spanish thermal resort.
