Arnoia Thermal is a thermal spa resort on the banks of the Miño River in the province of Ourense, Galicia, northwestern Spain, part of the internationally recognized Via de la Plata route and situated in the heart of Galicia's thermal-rich geothermal zone. The chloride-rich thermal waters emerge from the granite basement of the Ourense basin at elevated temperatures — the area around Ourense is the richest in thermal waters in Spain, with springs documented since Roman times — and are used for a range of balneological treatments at the modern spa complex. The setting on the Miño River, surrounded by vineyards of the Ribeiro wine designation and the gentle granite hills of inland Galicia, is one of the most scenically pleasant of any Galician thermal destination. Arnoia Thermal offers a high-quality thermal experience in the heart of Galicia's geothermal heartland, combining the therapeutic richness of the Ourense basin's extraordinary spring resources with the culinary and viticultural pleasures of one of Spain's most distinctive cultural regions.

Insider tip — Balneario Arnoia occupies a privileged spot on the banks of the Miño River in Galicia, with sodium-chloride waters that emerge at a steady 37°C throughout the year. The Roman road network once made this a stopping point for travellers between Ourense and Portugal. Modern facilities retain a classic Galician stone aesthetic while offering full hydrotherapy circuits. The surrounding Rías Baixas wine country makes this an excellent base for combining wellness with gastronomy.
