In the morning, the Biarritz Aquarium, in the Art Deco building at the Atalaye, with the seal tank you see from above and from below the water. You eat at the bar of the Les Halles market and spend the afternoon in Saint-Jean-de-Luz, whose beach is in a bay closed off by breakwaters where hardly any swell enters. Everything is less than an hour from San Sebastián. ## The day, hour by hour 9:00 · Departure. From San Sebastián, the AP-8 and A-63 to Biarritz, about 45 minutes. The aquarium has no car park of its own: the Port Vieux one, 240 metres away, has about 40 spaces and fills early; otherwise, the Sainte-Eugénie underground car park, 500 metres away. 10:00 · Biarritz Aquarium. You tour the Bay of Biscay from the coast to the depths and then more distant seas, with sea turtles, sharks, jellyfish and tropical fish. The average visit is an hour and a half. In November 2026 it opens from 9:30 to 19:00; the hours change with the season, so check the calendar on its website. Admission costs €17 for adults and €12 for ages 4 to 12. The seals' feeding time is not published: ask at the ticket office. 12:15 · Les Halles de Biarritz. A quarter of an hour's walk away. The covered market opens every morning until two and around it the bars serve portions and tapas. With children, the practical thing is to buy inside and eat at a high table outside. 14:30 · Saint-Jean-de-Luz and its bay. Twenty minutes south. The old town is almost entirely pedestrian and flat: place Louis XIV with its bandstand and rue Gambetta lead to the beach, in a bay closed off by breakwaters. From June to September it is the calmest beach on the coast for swimming with children; the rest of the year, for playing in the sand. For dessert, the macarons from Maison Adam, on the same square. 17:30 · Return. Half an hour to San Sebastián. ## What to eat at the market Bayonne ham, Ossau-Iraty sheep's cheese, fried fish and tapas at the bars around. It is quick, simple food, good for children who cannot sit through a long meal. Arrive before one: at two the stalls pack up. ## With a pushchair, in the rain and with older children The walking route through the Atalaye gardens is not practicable with a pushchair or wheelchair: the aquarium gives an accessible route on its website that goes round the plateau. In the rain, the aquarium is Biarritz's handiest plan, so arrive at opening. With teenage children, swap the aquarium for an introductory surf lesson at the Côte des Basques, from €45. From April to October, the Nivelle V also does a short 45-minute trip along the corniche from the port of Saint-Jean-de-Luz. ## Cómo llegar ### By car AP-8 and A-63, toll road, about 45 minutes to Biarritz; from Biarritz to Saint-Jean-de-Luz, twenty minutes. In Saint-Jean-de-Luz, paid car parks at the harbour and Cœur de Ville. ### Without a car Topo to Hendaye and regional train to Biarritz; the station is far from the centre, so take the Txik Txak N4 bus, which stops at the Port Vieux. To return, train from Biarritz to Saint-Jean-de-Luz and Hendaye. ## Consejos ### Buy the ticket on the website The aquarium recommends it to avoid queuing, and in holidays there is fast access for those who bring it. ### Ask about the seals' time It is not published. Plan the visit around it. ### Bring a towel even if it is not summer In the bay children end up in the water up to their knees. ## Cuándo no ir A Sunday in August with the car in Biarritz at midday. Traffic jams and full car parks. That month, start with Saint-Jean-de-Luz and leave the aquarium for the afternoon. ## Preguntas frecuentes ### From what age is the aquarium worth it? From three or four: the seals, sharks and turtles hold their attention. ### How much does it cost? €17 for adults and €12 for ages 4 to 12. Ages 13 to 17, €15. Under-16s must be accompanied by an adult. ### Is Saint-Jean-de-Luz beach safe for children? It is the calmest on the coast: it is in a bay closed off by breakwaters where hardly any swell enters. In summer swim in the supervised area. ### Does it work in the rain? Yes. The aquarium is indoors and so is the market. Only the beach afternoon depends on the weather. ### Can I go with a pushchair? Yes, following the aquarium's accessible route. The old town of Saint-Jean-de-Luz is flat.
