Each passenger can take a maximum of 20 kg of luggage to the island. However, it is important for you to consider the weight that you can carry by yourself, and to pay special attention to valuable objects. Mar de Ons is not liable for any luggage or personal objects lost or stolen.

It is important to take into account the objects that you are not allowed to bring on board, as they are considered illegal or dangerous, and the forbidden objects.

For safety reasons, it is forbidden to carry any kind of objects that may put the passengers safety at risk in the hand luggage. This includes objects such as:

  • Explosives, ammunition, pyrotechnic elements or sparklers, and dangerous weapons.
  • Gases (flammable, not flammable, intensely refrigerated or poisonous) such as camping gas, oxygen, propane and butane.

It is completely forbidden to disembark any type of animal on Ons Island, except for guide dogs accompanying blind persons. If you are interested in visiting Ons Island and you need pet accommodation services, there are available for you in the city of Vigo.

We consider pets the following animals: dogs, cats and those harmless animals that board wearing a lash, collar and muzzle. The pet must stay on the outside part of the boat for the entire journey.

Please ensure that you carry your pet’s medical card with you and that your pet’s vaccinations and dewormings are up to date.

Boarding time

In order to board, you should go to the signalled point at least 15 minutes prior to departure. Passengers must be in the corresponding queue and hold their ticket on their hands, so that the boarding goes quickly and efficiently, making it easier for the boat to depart on time.



There are no rubbish containers on the island, so we recommend bringing bags for rubbish collection, etc.

Wearing sports shoes and comfortable clothes is recommended. Do not forget to bring your raincoat or some warm clothing for the boat trip, in case of possible temperature changes.

Bring water with you and try to drink plenty of it during your visit. Long exposures to the sun, summer temperatures and wind can cause dehydration problems.

Do not forget items such as your sunglasses, a cap or your sunscreen.

Walk only along the paths that are authorised for public use (free-visit areas), following the indications on the signs.

It is advisable to bring a camera, a video camera, goggles and binoculars.

Basic Services

Health care – As of todat, none of the archipelagos has health care staff working permanently. Health care services are available during the months of July, August and September only, coinciding with the greatest flow of tourists. On Ons Island, the health care services are located at the crossroads of Curro neighbourhood on the way to the lighthouse. There is a nurse and a lifeguard.

Drinkable water – The existence of natural springs was one of the reasons that favoured human settlements on the island since the ancient times. However, it is important to take into account that drinkable water is scarce, especially during the driest periods, which coincide with the greatest flow of tourists. The fountains on Ons Island are signalled, but drinkability is not guaranteed. It is this advisable to bring plenty of water with you to visit the island, since this is a windy area with a great amount of salt in the air, which favours dehydration under the sun.

Public restrooms – There are no public restrooms independent from other services on Ons Island, but the restrooms that bars have for their customers will be publicly available for you to use. Please note that these restrooms are not accessible for people with reduced mobility.

Visitor Services

Information Stand: there is an information stand on Ons Island, right at the end of the access dock, opposite As Dornas beach. At this point, you can ask for any information that you may need about the National Park, concerning services and possible activities that you may carry out on the island. Its main goal is to provide the visitors with all the information allowing them to enjoy their visit to the fullest.

Ons Visitor Centre: This interpretation centre is located on the Curro neighbourhood, opposite the church, where the old Ons Civic Centre used to stand. It is based on the heritage and ethnography of the island and the old islanders. Ons, an island of legends and traditions, has a long history full of events that had an impact on the survival of its inhabitants and contributed to a culture having a wide knowledge of nature and holding popular beliefs that marked the daily chores. The exhibition shown at this centre includes examples of the natural value of this archipelago, as well as an in-depth trip through the history, the customs and the life on the island in ancient times. The centre is generally open during the summer season.

Viewpoints: Even though there are several places on the island from where the landscape can be admired, only some of them are considered viewpoints, which are accessible for most of the visitors because of their landscape interest, spaciousness and location. The Fedorento viewpoint in Ons offers an impressive panoramic view of Ons Island, Cíes Islands, Costa de la Vela and the continental area which is closest to the archipelagos.
