Welcome to Illa de Ons
In summer you can get away from urban civilisation by hopping on a boat to vehicle-free Illa de Ons at the mouth of the Ría de Pontevedra. Part of the Parque Nacional de las Islas Atlánticas de Galicia, the island is 5.6km long with one tiny village, several sandy beaches, cliffs, ruins, four walking trails (circuits of between 1km and 8km) and rich bird life. You're unlikely, however, to find it empty: up to 1800 visitors are allowed on the island at any one time. May, June and September are the most tranquil.
