Cíes Islands 2026: How to Get the Permit Before You Book the Ferry

The Cíes Islands look like the kind of place you can simply decide to visit.

That is part of their danger.

White sand, Atlantic water, hiking trails, Vigo nearby, ferries in season, a beach once turned into a travel myth by foreign newspapers. The image says "easy day trip". The reality says: authorization first.

To visit the Cíes Islands during high season, you need prior authorization from the Xunta de Galicia before buying the boat ticket. The official authorization portal says the permit is necessary during Easter and from May 15 to September 15. The Galician Atlantic Islands National Park also states that Cíes and Ons require prior authorization during high season before purchasing the shipping-company ticket.

This is not complicated.

It is just unforgiving if you learn it too late.

The order matters

The correct order is simple.

First, request the authorization. Then buy the ferry ticket from an authorised operator. Then keep the documentation for boarding and access.

Many travellers reverse that process mentally. They think the ferry is the main booking and the permit is a detail. In the Cíes Islands, the permit is the gate.

The National Park explains that visitor numbers are limited to reduce negative impacts on the islands, campers and private boat anchorages. It also notes that the marine areas host valuable seabeds susceptible to damage from navigation, anchoring and diving without proper regulation.

This is the thing to remember.

The Cíes are not a beach product. They are a protected national park.

Why the limit exists

The Cíes Islands are beautiful because they have not been allowed to become ordinary.

That is not an accident. Cars are not part of the visitor experience. Waste rules matter. Trails are controlled. Camping is limited. Access is structured. The Park rules prohibit leaving waste behind, disturbing wildlife, damaging vegetation, collecting shells, bringing domestic animals except guide dogs, flying drones without authorization and using noise systems that alter natural tranquillity.

These rules may sound strict.

They are the reason the islands remain worth visiting.

A fragile island cannot be treated like a normal beach near a city just because the boat ride is short.

Vigo, Cangas or Baiona?

Most first-time visitors think only of Vigo.

That is understandable. Vigo is the biggest and most obvious departure point. But ferries also operate from other Galician ports in season, depending on operator and date. The right port depends on where you are staying, the timetable and whether you are combining the islands with the Rías Baixas, Pontevedra, Baiona or a broader Galicia itinerary.

Do not choose the port only by name recognition.

Choose the port that gives you the cleanest day.

If you are staying in Vigo, the day is straightforward. If you are staying further down the coast, forcing everything through Vigo may not be necessary.

What kind of day is this?

The Cíes are not a serviced Mediterranean beach day.

This is Atlantic Galicia. The water is colder. The weather can shift. The landscape is more open and less polished. You come for beaches, yes, but also for walking, sea air, viewpoints, birds, sand, quiet and the slightly strange pleasure of being somewhere that does not behave like a resort.

Bring water, layers, sun protection and real shoes if you plan to walk.

Do not arrive as if there will be beach-club infrastructure waiting for you.

That misunderstanding ruins many good places.

Should you sleep there?

For most travellers, a day trip is enough.

But camping can make sense for people who want the island after the day-trip rhythm changes. It requires its own planning and authorization logic, and it is not luxury in the conventional sense. It is a way to let the islands become less transactional.

Do it if you want the nature.

Do not do it just because one night on an island sounds romantic.

What to avoid

Avoid buying ferry tickets before understanding the authorization.

Avoid old blog posts with outdated instructions.

Avoid treating the islands as a last-minute backup plan.

Avoid overpacking.

Avoid making noise.

Avoid expecting Mediterranean heat and Mediterranean water.

Most of all, avoid visiting the Cies as if the permit system were an annoyance rather than the condition that makes the visit possible.
