Balneario O Grove Thalasso is located in O Grove, a peninsula town in the Rías Baixas of Pontevedra Province, Galicia, jutting into the Arousa estuary — one of Galicia's most productive marine farming zones, renowned for the world's finest mussels and scallops grown in the clean, nutrient-rich Atlantic waters of the Arousa Ría. The chloride-rich thalassotherapy treatments draw on the extraordinary mineral richness of the Atlantic Ocean water surrounding the O Grove peninsula, harnessing the traditional marine therapy tradition that has made Galicia's ría estuaries among the most biologically productive and therapeutically rich coastal environments in Europe. O Grove's seafood cuisine — particularly its celebrated mussels, percebes (barnacles), and fresh fish served in the town's market restaurants — combined with Atlantic seawater spa treatments makes this one of the most sensorially complete marine wellness destinations on the Galician coast.
Insider tip — Situated on the O Grove peninsula jutting into the Arousa estuary in Galicia, this thalasso center pumps seawater from the Atlantic directly into its treatment pools alongside thermal mineral waters. The marine setting amid the Rias Baixas, with mussel rafts visible across the silvery estuary, is uniquely atmospheric. Sodium-chloride seawater at 42°C is used in pressurized jet treatments that target musculature and joint inflammation. Reserve the outdoor seawater hydrotherapy pool for late afternoon when the light over the ria turns golden.
