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.
By private boat you can visit Calquera every day of the year but you must have navigation permits. and anchorage issued by the National Park.
The form to request a navigation permit can be downloaded here and the documentation that you have to join together. The applications, once completed, can be sent by email, regular mail or fax to the National Park offices.
Once you have obtained the navigation permit, you will be able to request anchoring permits electronically for those days when you do not want to anchor in the islands. The website to process anchorages is: www.iatlanticas.es
