Spain's hot springs are aguas termales, and at least 16 of them sit in this directory across the mainland. The free riverside pools of Termas de Outariz line the water through Ourense, while Balneario de Archena near Murcia keeps a grand nineteenth-century spa. 6 of the 16 listed here are free to enter. Galicia and the north hold most of them.
Galicia in the northwest is Spain's hot-spring heartland, centred on the thermal city of Ourense. The free riverside pools of Termas de Outariz and Pozas da Chavasqueira sit along the water, while Termas de Prexigueiro near Ribadavia adds landscaped outdoor baths. Several of the directory's Spanish springs lie in this northwestern region.
The northern mountains gather classic balnearios across Cantabria, La Rioja, and Aragon. Bathers soak in the free river pools of Pozas de Arnedillo in La Rioja, the Pyrenean spa at Balneario de Panticosa (Termas de Tiberio), or the cave baths of Balneario de Puente Viesgo in Cantabria. Many of the listed Spanish springs sit across these northern provinces.
Andalusia in the south adds warm wild pools and a historic spa town. The free terraces of Pozas de Alhama de Granada and the reservoir-side Banos de Zujar draw local bathers, while Balneario de Lanjaron (Aquatherma) anchors a long-established spa town. A handful of the springs listed here lie in the south.
Eastern and central Spain round out the map through Murcia, Valencia, and Extremadura. Balneario de Archena near Murcia runs a grand riverside complex, while La Fontcalda near Gandesa offers a free gorge pool and Balneario de Alange preserves Roman-era baths. These eastern sites complete the directory's Spanish entries.
Spanish bathing splits between two traditions, the free aguas termales of Galicia and the paid balneario spa hotels of the nineteenth century. Ourense alone keeps several free riverside termas within a short walk, which sets Spain apart from countries where every spring is ticketed. Of the 16 springs listed in this directory, 6 are free and 10 are paid balnearios. Water at the Ourense pools runs near 40 degrees Celsius. These sit within the wider hot springs in Europe.
