On old maps, O Grove was an island. Today, it is joined to the mainland thanks to the south-westerly winds, which have slowly gathered sand to form the isthmus of the beach of A Lanzada. O Grove throws a famous shellfish festival the second week of October, but you can enjoy the day's catch in taverns and restaurants year-round. From O Grove, you can cross a bridge to the island of A Toxa (La Toja), famous for its spas—the waters are said to have healing properties. Wide, soft sand beaches meet exquisite and clean waters on this Spanish peninsula, which are as celebrated for their fruitful fish bounty as they are their beauty.
