Introduction
Ons Island is one of Galicia’s most beautiful coastal destinations, offering a peaceful combination of white-sand beaches, rugged cliffs, green landscapes, and traditional island culture. Located within the Atlantic Islands of Galicia National Park, the island provides a more natural and tranquil experience than many of the busier beach destinations along the RÃas Baixas.
The island is particularly attractive to travelers who enjoy walking, beaches, photography, wildlife, and outdoor adventures. Its network of marked trails crosses open countryside, coastal landscapes, and traditional settlements, while several beaches provide opportunities to relax beside the Atlantic.
Ons Island is also different from a conventional holiday resort. Because it is part of a protected national park, visitor numbers and activities are regulated to protect the environment. During the high season, day visitors arriving by authorized passenger vessels need prior authorization from the Xunta de Galicia, and the official park currently limits the Ons archipelago to 1,300 visitors per day.
Most travelers visit as a day trip from mainland ports such as Bueu, Sanxenxo, and Portonovo, while overnight visitors can use the authorized campsite on the island.
Whether you are planning a beach day, a hiking adventure, or a longer RÃas Baixas itinerary, these are the 7 best things to do on Ons Island.
Featured Snippet
The best things to do on Ons Island include relaxing on its beaches, hiking the island’s marked coastal trails, visiting the lighthouse, exploring the traditional village area, discovering the island’s viewpoints, enjoying local seafood, and observing its protected natural environment. During the main season, visitors arriving by authorized ferry need prior Xunta de Galicia authorization.
Why Visit Ons Island?
Ons Island provides an opportunity to experience one of Galicia’s most distinctive protected coastal environments.
Unlike a conventional resort destination, the island has relatively little development and a strong connection with traditional maritime life. The landscape combines open grassy areas, low woodland, rugged cliffs, sandy beaches, and small settlements.
The island is particularly rewarding for travelers who enjoy exploring at their own pace. Rather than moving between numerous commercial attractions, visitors can spend the day walking trails, stopping at viewpoints, swimming, enjoying a meal, and observing the surrounding landscape.
Its location within the national park is also important. The protected status means visitors must follow regulations designed to preserve wildlife, vegetation, archaeological features, and coastal ecosystems. Motor vehicles and bicycles are generally prohibited on the island, while visitors are expected to remain on signposted trails and take their waste back with them.
7 Best Things to Do on Ons Island
1. Relax on Area dos Cans Beach
Area dos Cans is one of the best-known beaches on Ons Island and a natural choice for a relaxing start to your visit.
The beach features fine sand and relatively sheltered waters, while the surrounding vegetation and rocky coastline create a beautiful natural setting.
It is an excellent place to spend time after arriving by ferry before beginning a longer hike around the island.
Best For: Families, swimmers, couples, and beach lovers.
Travel Tip: Bring your own beach essentials because facilities on a protected island are more limited than those at mainland resorts.
2. Hike the Ons Island Trails
One of the best ways to experience Ons is on foot.
Several signposted routes cross the island, allowing visitors to explore different landscapes without needing a vehicle. Trails pass through grassy areas, vegetation, traditional settlements, and coastal viewpoints.
Because only pedestrian traffic is permitted on the ordinary trails, walking is an important part of the Ons experience.
Choose a route based on your available time and fitness level rather than trying to see every corner of the island in one day.
Best For: Hikers, photographers, families, and nature lovers.
Travel Tip: Bring water, sun protection, and comfortable walking shoes. The national park itself recommends carrying water, sunscreen, warm clothing, and appropriate footwear.
3. Walk Toward the Ons Lighthouse
The Ons Lighthouse is one of the island’s most recognizable landmarks and an excellent destination for walkers.
The route toward the lighthouse provides an opportunity to experience the island beyond the beaches. As you move inland and uphill, the landscape opens up, creating views over the Atlantic and surrounding coast.
The lighthouse itself also demonstrates the island’s long maritime connection.
Best For: Photographers, hikers, couples, and travelers interested in maritime heritage.
4. Discover Buraco do Inferno and the Coastal Cliffs
The rugged coastal landscape around Ons becomes particularly dramatic near its cliffs and natural formations.
Buraco do Inferno is one of the best-known natural features on the island. The name refers to a dramatic coastal geological formation associated with the power of the Atlantic.
The surrounding area offers striking views and is particularly impressive when the sea is active.
Visitors should remain on the designated paths and respect barriers because cliffs and exposed coastal areas can be dangerous. The national park specifically requires visitors to stay on signposted trails and prohibits access to prohibited areas.
Best For: Nature enthusiasts, photographers, and experienced walkers.
5. Explore the Traditional Village of Ons
Ons Island is not simply a natural landscape. Its traditional settlements provide insight into the island’s maritime history and community life.
Walking through the village area allows visitors to see traditional houses and understand how people historically adapted to life on an Atlantic island.
The Ons Visitor Centre, located in the Curro area, provides additional information about the island’s natural and ethnographic heritage when open during the visitor season.
Best For: Cultural travelers, history enthusiasts, and families.
6. Enjoy Traditional Galician Seafood
Food is an essential part of the Ons Island experience.
The island has a small selection of dining facilities, particularly around the main settlement and visitor areas during the season. Travelers can look for traditional Galician dishes, especially seafood and octopus.
A meal on the island can be a memorable addition to a hiking and beach itinerary, particularly when combined with a relaxed afternoon overlooking the coast.
Best For: Food lovers, couples, and travelers seeking an authentic Galician experience.
Travel Tip: Bring extra water and snacks if you plan to spend a long day on the island because facilities are limited compared with mainland destinations.
7. Enjoy the Island’s Natural Wildlife and Ocean Views
The final activity is simply taking time to observe the island’s natural environment.
Ons forms part of a protected marine-terrestrial national park, and its value comes from the combination of coastal habitats, vegetation, cliffs, beaches, and surrounding waters.
Visitors may encounter seabirds and other wildlife while walking the island. However, the park asks visitors not to feed animals, disturb wildlife, damage vegetation, or remove natural materials such as shells.
For photographers, the combination of green hills, white beaches, granite rocks, and Atlantic horizons creates excellent scenery throughout the day.
Best For: Photographers, birdwatchers, nature lovers, and slow travelers.
