Gran Hotel La Toja is an iconic thermal spa hotel on the Isle of La Toja, a small island in the Ría de Arousa estuary of Galicia in northwestern Spain, where naturally occurring sodium, chloride, and iodine-rich mineral spring waters of exceptional concentration have made the island famous since the late nineteenth century. According to legend, the springs were discovered when a sick donkey left on the island was later found mysteriously recovered and full of vigor, with the mineral-encrusted spring water credited for the change — a story that launched one of Spain's most celebrated spa and beauty traditions. Gran Hotel La Toja, opened in 1907, has welcomed royalty, politicians, and celebrities across its history, and its mineral waters — used in baths, thalassotherapy rituals, and the famous La Toja cosmetic products sold worldwide — continue to define the spa heritage of this uniquely beautiful Galician island within a long thermal tradition.
Insider tip — La Toja is a storied Galician spa island whose iodine-rich seawater and thermal springs have attracted European royalty and celebrities since the late 19th century. The Grand Hotel's thalassotherapy and thermal circuits combine Atlantic seawater with the island's own mineralised springs for a distinctive marine-thermal hybrid treatment. The shell-encrusted chapel on the island and eucalyptus groves create an atmosphere unlike any other Spanish spa destination. The seafood in the adjacent town of O Grove, particularly barnacles and Galician oysters, provides an exceptional post-soak culinary experience.
