Points of interest

In Ons don’t miss the mysterious “furnas”, granite sea caves cut by the waves, such as the mythical “Burato do Inferno”, which was “believed to go all the way down to hell, and on stormy nights the voices of the dead could be heard”.

There is a regular passenger transport service by sea to the Cíes from the port of Vigo, Baiona and Cangas during high season. There is the same service to Ons from Portonovo, Sanxenxo, Bueu and Marín. Services of a guide to Cortegada from Carril (Vilagarcía de Arousa). (Sálvora has no transport service by sea, and access to it is restricted.)

This national park has a controlled access with a maximum of 2,200 people daily allowed on the islands.

The area has also become famous as a starlight destination. The Starlight Foundation is a non-profit organization that was founded in 2009 to promote the protection of the night sky and the development of “astrotourism” and there is an ever growing list of starlight destinations in Spain to visit.

This sea-land ecosystem has a laurel forest and over 200 species of seaweed whilst he beds of kelp are also of importance in these waters. The most representative land flora can be found on cliffs and dunes.
