What to do in the French Basque Country when it rains: 8 ideas around Ainhoa
Rain is part of the landscape in the French Basque Country.
It is one of the reasons the hills around Ainhoa stay so intensely green, ferns cover the mountainsides and the forests are so lush. After a shower, the colours deepen, clouds hang over the peaks and the valleys can take on an almost mysterious atmosphere.
So no, rain is not necessarily bad news.
But realistically, when it settles in for several hours, a muddy mountain walk or a day on the beach can lose some of its appeal.
Fortunately, there are plenty of things to do in the French Basque Country when it rains, many of them within easy reach of Ainhoa.
1. Go underground at the Sare Caves
Just a few kilometres from Ainhoa, the Sare Caves – Grottes de Sare are almost made for a rainy day.
A guided visit takes around an hour and explores the geology of the caves as well as prehistory, Basque mythology and the human history of these mountains. The temperature underground stays at around 14°C throughout the year, so take a jacket even in summer.
Rainy days are particularly popular, so it is worth booking ahead.
It is also a fascinating way to understand the landscape around Ainhoa — only this time from underneath it.
2. Discover Basque history in Bayonne
A grey day is a very good excuse to visit Bayonne.
The Basque Museum and the History of Bayonne explores traditional architecture, rural life, pelota, crafts, clothing, maritime history and many other aspects of Basque culture.
After spending time in Ainhoa, you will recognise a surprising amount: traditional Basque houses, funerary stelae, domestic objects and customs that are still visible in the region today.
3. Enjoy Biarritz without needing sunshine
Biarritz is about much more than the beach.
The Biarritz Aquarium is an excellent option when the weather is genuinely wet, with marine life from the Bay of Biscay as well as seals, turtles, tropical fish and other species.
For something different, the Cité de l’Océan focuses on the ocean, waves and surfing through interactive and immersive experiences.
And there is always a bonus: if the rain stops while you are there, you are already beside the Atlantic.
4. Visit Abbadia, the château-observatory
Near Hendaye, Château d’Abbadia is one of the most unusual places to visit in the French Basque Country.
Built in the 19th century for Antoine d’Abbadie — explorer, scientist and astronomer — the château combines neo-Gothic architecture with an observatory, library and interiors inspired by his extensive travels.
It is precisely the sort of place that is easy to postpone when the sun is shining and you would rather be outside — and then very satisfying to have saved for a rainy day.
5. Use the weather as an excuse to eat
This may be the most Basque solution of all.
A rainy day is perfect for slowing down and discovering local food: Ossau-Iraty cheese, gâteau basque, charcuterie, chocolate and Espelette pepper.
In Sare, you can learn more about the history and making of gâteau basque, while Espelette has plenty of producers and food shops to explore at a leisurely pace.
And if you return to Ainhoa with some local cheese and a gâteau basque for later, the day certainly has not been wasted.

6. Spend the morning at a covered market
Covered markets are particularly enjoyable when the weather turns wet.
In Saint-Jean-de-Luz, Les Halles is a wonderful place to browse fish, cheeses, charcuterie, bread, fruit and vegetables and other regional produce.
Bayonne has its own covered market too, with cafés and the historic centre immediately outside.
This works especially well when the forecast is changeable: spend the morning under cover, have lunch, and then head outside if the sky begins to clear.
7. Spend a few hours at the spa
If it is raining outside, being somewhere warm and relaxing suddenly seems very sensible. The spa Oppocalme in Ainhoa is difficult to improve on.
There are also spas and thalassotherapy centres along the coast around Saint-Jean-de-Luz, Anglet and Biarritz.
It does not necessarily need to fill the entire day. A few hours in a spa can be enough to transform a grey afternoon into something you actively look forward to.
8. Don’t plan too much
And then there are the days when it rains… until it doesn’t.
Weather in the Basque Country can change quickly, particularly close to the mountains. A wet morning can turn into a beautiful late afternoon.
On days like these, there is no need to fill every hour with indoor activities. Have coffee, enjoy a long lunch, visit a museum or browse a few shops — and head outside when the clouds lift.
Ainhoa is particularly beautiful after rain.
The white façades stand out more clearly, the mountains seem closer and the countryside takes on that deep green colour that is such an essential part of the Basque landscape.
Rain is part of the French Basque Country too
You could ask whether rain in the Basque Country is a blessing or a curse.
The answer is probably a little of both.
It can complicate a hike, change your plans for a beach day or make staying under the duvet seem particularly attractive.
But without the rain, the Basque Country would not look like the Basque Country we know: its pastures, forests, streams and green mountains owe a great deal to it.
So when it rains, simply change the plan.
For even more ideas, the French-language website Que Faire au Pays Basque also has a regularly updated guide to activities for rainy days.
