History of Ons Island
Petroglyphs found in Ons

Visiting the island of Ons is a journey in which to contemplate thousands of years of history. Pliny the Elder already described the island in his works on the Iberian Peninsula. He called it insula Aunios, a name with an Indo-European root that clearly refers to water and its flow. However, there is information about settlements in Ons that date back much further, Paleolithic remains have been found, as well as remains from the metal age. The remains of two castros that developed on the islandwhose splendor was lived at the end of the Bronze Age. A castro is a fortified settlement characteristic of the Celtic people, generally pre-Roman, which is typically located in the Rías Baixas and also throughout the northwest of the peninsula.

Although we do not have much data, it is known that in the Middle Ages it was a place of congregation of hermit monks, and over the years, the ownership of the archipelago passed through various hands. Thus, until the tenth century it was owned by the Kings of Galicia, then passed to the Archbishopric of Santiago de Compostela, which in the sixteenth century donated the land to the noble family Montenegro.

Like many Atlantic islands of Galicia, in its past it was a refuge of pirates, always inhabited also by all kinds of sailors and settlers during the Modern Age. In the 19th century, the islands became part of the properties of the Marquisate of Valladares, which established a small salting industry, and changed hands again at the beginning of the 20th century. In the middle of the last century, for social and labor reasons, the island experienced a population boom, reaching 530 people in 1955.

In 1981, Ons was ceded to the Xunta de Galicia and thus became part of the national public domain. It will also be recognized as a National Park and, since 2001, the archipelago has been part of the Parque Nacional Marítimo-Terrestre das Illas Atlánticas de Galicia.The islands of Cíes, Sálvora Island and Cortegada Island.



There are many travelers who hesitate about visiting Ons Island or the Cíes Islands. Trying to decide between two trips to different places is not easy! Without leaving Galicia, is it preferable to visit San Simón Island or San Vicente del Mar? Is it possible to eat higher quality seafood in the Ría de Vigo or in the Ría de Arousa? Is Melide Beach more beautiful than Viñó or Nerga Beaches? Rías altas or Rías Baixas? Vacation in July or August?

Faced with these dilemmas, We can only answer that, if it’s all about travel and enjoyment, why not visit both? It is true that, in recent years, the island of Ons has been somewhat overshadowed by the Cíes Islands and that, although the whole group is part of the Parque Nacional das Illas Atlánticas, the latter have enjoyed greater popularity and publicity. Perhaps it is due to the choice of the British newspaper The Guardian, some years ago, of Rhodes Beach as the best beach in the world, with its fine white sands. However, Ons is gradually removing the complexes, making it clear that on this island there are as many natural wonders to admire and beaches to enjoy as on its sister islands.

  • ROUTE DO CASTELO. Perhaps the most popular of all the routes on the island, a light walk of only 1.1 km. and medium difficulty – easy. It starts at the emblematic Praia das Dornas, where you can see some old sailing fishing boats (the typical dornas), and continues along the coastline and a small willow forest, heading north, to the viewpoint do Castelo, with excellent views of the entire Ría de Pontevedra and its beaches.

Visiting Ons Island: Activities and routes

In addition to hiking and trails on land, it should be remembered that this is a Maritime Terrestrial Natural Park. Whether visiting Ons Island or the Cíes Islands, the best way to get to know the mysteries hidden in the sea is to dare to dive into its waters, practicing snorkeling, free diving or scuba diving. The Pontevedra estuary is home to different varieties of algae, fish and rock formations that serve as an environment and shelter for all types of marine fauna and flora. If diving is not your thing, you can always enjoy a catamaran trip in which you can see through its deck and discover all the secrets of nature under the sea of the estuaries.

The Camino de Santiago can also be traveled by boat on its maritime route. Towards Iria Flavia, the Camino passes near the islands of Ons and Sálvora. It is the only route that runs mainly by boat, to finally join the Portuguese route.



Visiting the island of Ons is synonymous of a great gastronomic experience. Seafood, fish, pies, wines... all the natural flavor of Galicia is enjoyed twice as much listening to the sea, watching the sky, contemplating Bueu, Onza Island or the Cies Islands in the background.

Since 1945, Casa Acuña has been one of the most highly regarded restaurants by all visitors to the island. Palmira Acuña, who runs this restaurant with capacity for 200 diners, boasts of preparing the best octopus in Galicia, and no wonder, since her cuisine has been recognized with several awards. All the fish and seafood prepared are fresh, from the Rías Baixas, and are accompanied by the best wines of the area. For the customer it is like eating at home, because the concern of the staff for customer service and quality make Casa Acuña one of the best restaurants in Galicia. It is open every day from Easter to October.

Another good option to eat on the island of Ons, a few meters from Casa Acuña, is the Bar O Pirata. Specialized in churrasco and seafood, it offers menu of the day and is open every day during the high season, from June 22 to September 15. It is a meeting place on the island, perhaps thanks to the fact that it is one of the restaurants that offers the best views of the estuaries from its terrace, in a privileged natural environment.
