O Grove Seafood Festival 2026: the best way to arrive is by boat from Vilanova

Every October the same thing happens: O Grove becomes the gastronomic capital of Galicia, half the country wants to go to the Seafood Festival (Festa do Marisco), and the road across the A Lanzada isthmus turns into a queue of cars hunting for parking spaces that don't exist. We rent out our skippered boat from the port of Vilanova de Arousa, and for years we've been playing it differently: arriving at the festival by sea, sailing across the Ría de Arousa, with a stop among the mussel rafts to work up an appetite and a berth just a short walk from the seafood marquees.

In this article we'll tell you what the Seafood Festival is, what to eat (and what's really worth it), and how we put together a full boat day that ends with a plate of spider crab in front of you and not a single minute wasted looking for parking.

What is the O Grove Seafood Festival?

The Festa do Marisco do Grove has been held since 1963 and is one of the biggest food festivals in Spain: it holds National Tourist Interest status and each edition draws hundreds of thousands of visitors over about ten days, usually in the first half of October, around the Pilar bank-holiday weekend.

The format is simple and glorious: huge marquees next to O Grove's harbour where local fishermen's guilds and producers serve portions of ría seafood at reasonable prices. You buy your tickets, sit at long shared tables with people from everywhere, and the parade begins:

• Spider crab and brown crab, boiled — the kings of the festival.
• Oysters from Arcade and the ría, shucked on the spot.
• Scallops and queen scallops, grilled or gratinated.
• Raft-grown mussels, steamed or in escabeche — the very same ones you'll see growing on the rafts on your way over by boat.
• Carril clams, razor clams, cockles, shrimp, velvet crab…
• And to go with it all, Albariño from the Rías Baixas — what people here have always drunk with shellfish.

Around the marquees there are concerts, cooking showcases, traditional dorna boat races and an atmosphere somewhere between a Galician romería and a serious food fair. This is not a white-tablecloth gourmet event: it's real seafood, in quantity, eaten with your hands and a paper napkin. Exactly as it should be.

The problem: getting there (and parking) in October

O Grove is a peninsula joined to the mainland by a narrow isthmus at A Lanzada. In August the tailbacks are already a thing; during the Seafood Festival, with hundreds of thousands of visitors squeezed into ten days, it gets serious: queues to get in, park-and-ride lots full by mid-morning and twenty- or thirty-minute walks to the marquees.

And here's the good part: O Grove has a harbour, and the festival is held literally next to it. Arriving by sea isn't a whim — it's the most comfortable (and most beautiful) way to turn up at the festival.

Our route: from Vilanova to the Seafood Festival across the ría

From the port of Vilanova de Arousa to O Grove it's a gorgeous crossing of around an hour of easy cruising, depending on sea conditions and how many stops we make. On festival days our usual route looks like this:

1. Leaving Vilanova, heading south among the mussel rafts

We leave Vilanova harbour and head south-southwest with the Illa de Arousa to starboard. Soon we're inside the maze of mussel rafts (bateas), the wooden platforms that make the Ría de Arousa Europe's biggest mussel producer. Gliding slowly between them in the low October light is the best possible introduction to what you're about to eat: much of the shellfish served in the marquees is grown right here.

2. Punta Cabalo and the west coast of the Illa

We round the Punta Cabalo lighthouse on the northern tip of the Illa de Arousa and run down its west coast. In October this stretch is quiet, free of the summer boat traffic, and it's easy to come across dolphins entering the ría after the fish shoals. If the day allows, a short stop off Carreirón or the Areoso islet for a coffee on board is priceless.

3. Arriving in O Grove by sea

Entering O Grove harbour, with the town facing the water and the festival marquees along the seafront, is one of those moments you remember. We tie up, and five minutes on foot later you've got a spider-crab ticket in your hand while the people who came by car are still circling the isthmus.

4. The festival, at your own pace

From here the plan is yours: seafood portions, Albariño, music and a stroll around the harbour. Our advice after many years: don't fill up on the first thing you see — start with oysters and queen scallops, move on to the spider crab, and save room for the gratinated scallop at the end.

5. Back to Vilanova at sunset

In October the sun sets early, and the return to Vilanova often coincides with the ría turning golden, the mussel rafts in silhouette and the water like a mirror. Honestly, the best after-lunch moment there is.

How much it costs and how it works

Our boat departs from the port of Vilanova de Arousa with skipper included — you don't need any boating licence, we take care of everything to do with the sea. It's an 8.5-metre boat, comfortable and seaworthy, for a maximum of 6 guests plus the skipper.

• Full day: €500 — the option we recommend for the Seafood Festival: a relaxed crossing with stops, plenty of time at the festival and a sunset return.
• Half day (4 hours): €300 — possible if you only want the crossing and a quick meal, though on festival days it feels short.
• Fuel is charged separately, depending on the route we do.

If you're a group of 4–6 people, do the maths: the full day works out at under €100 a head for a private skippered boat, no traffic, no parking, and a route across the ría that's worth the trip on its own.

Practical tips for doing the festival by sea

• Book early. The Seafood Festival dates are the most in-demand of the autumn and we only run one outing per day.
• Dress in layers. The October crossing is chilly even on sunny days; bring a windbreaker on board. The full list is in our guide on what to bring on a boat day.
• Carry cash for the marquee tickets; the ATM queues in O Grove on festival days are legendary.
• Stay flexible with the weather. October in Galicia serves up both spectacular days and stormy ones. We follow the forecast with you in the days before and, if the outing needs to move, we move it without drama — more on this in our article on tides and weather in the ría.
• If your dates don't match the festival, no problem: ría seafood is just as good all autumn long in Cambados, O Grove or the Illa de Arousa, and the route is the same.

Book your boat for the Seafood Festival

October is our favourite month for this route: a calm ría, low golden light, dolphins following the fish shoals in, and the best seafood of the year waiting in O Grove.
