Arnoia is one of the leading thermal spa towns in the province of Ourense, one of the most important thermal centres in Europe, which in recent years has become linked to the Volta Ciclista a España, both as a sponsor and by hosting several of its stages.

Located in the O Ribeiro region, its strategic position gives it a mild climate for much of the year. The canyon of the River Arnoia, the presence of the River Miño and the thermal waters are its main hallmarks of identity, together with surroundings of great scenic interest, where the Ribeiro monasteries, the vineyards and the historic quarter of Ribadavia stand out.
