The Ons archipelago, in front of the Pontevedra estuary, is made up of two islands; Ons, the largest and still populated, and Onza, smaller and whose surface is a reserve area.

It has a coast of gently sloping cliffs and numerous "furnas" such as Buraco do Infierno and sandy areas, especially on the east coast, among which the Melide beach and dunes stand out.

A characteristic of Ons is the rocky platform that surrounds it, forming a shallow and very rich seabed.

In addition to its natural values, the island of Ons stands out for its ethnographic and cultural interest, since it had a large island population that had to adapt to living in the middle of the sea.

You can access the Library section to consult and download more brochures and resources about the Islands.

How to get there?

By maritime public transport

In high season

Easter Week, and from May 15 to September 15

The transport companies that provide these services are usually based in the ports of Bueu, Sanxenxo and Portonovo. Each season these companies establish their routes and schedules so it is advisable to consult them beforehand to approach the islands on these dates.

The daily visitor limit for the Ons archipelago in high season is 1,300 people per day, so it is necessary to have prior authorization from the Xunta de Galicia when buying the ticket from the shipping company. Access more information and permissions website HERE.

In the off season

Rest of the year

Ons can only be visited in an organized group with a guide, so visitors must contact the authorized shipping companies that organize the visiting groups. The maximum number of visitors per day this season is 250-450 people. The guide must be identified as accredited by the National Park, and cannot go with more than 25 people in the group.

The contacts of the shipping companies can be consulted at the end of this same page.

By private boat

The visit can be made any day of the year, but it is necessary to have the navigation and anchoring permits issued by the National Park. The form to request navigation permission can be downloaded on this website in the section of authorizations and it also indicates the documentation that must be attached. The applications, once completed, can be sent by email, regular mail or fax to the National Park offices.
Once the navigation permission has been obtained, you can request the permissions of anchoring for those days you want to anchor in the islands.
The daily limit in this archipelago is 60-70 anchorages/day distributed in two areas (Castelo and Melide) in the waters of the Park.
