Just across the French border, the Côte Basque offers a fascinating cultural continuation with a different flavour. Elegant Biarritz was once Europe's most fashionable resort and retains grand Belle Époque hotels, excellent surf beaches, and a vibrant food market. Saint-Jean-de-Luz is a perfectly preserved Basque fishing town with an outstanding chocolate and gâteau Basque tradition.
The French Basque Coast offers a seamless cultural continuation across the Spanish-French border, accessible from San Sebastián in under an hour by train or car. The two principal destinations — Biarritz and Saint-Jean-de-Luz — sit 35 and 20 kilometres north of San Sebastián respectively, making them natural partners for a combined day trip through the Côte Basque.
The most enjoyable public-transport route begins with EuskoTren from San Sebastián's Amara station to Hendaye, the last Spanish stop on the coastal line. The journey takes around 35 minutes through attractive coastal scenery. From Hendaye, French SNCF TER trains connect north to Biarritz in a further 20–25 minutes. The full cross-border journey costs roughly €8–12 each way. By car, the A-63 motorway from San Sebastián crosses the border at Biriatou and reaches Biarritz in 35–45 minutes depending on border traffic.
Biarritz was the playground of 19th-century European royalty — Empress Eugénie, wife of Napoleon III, transformed it into a fashionable resort town. Grand Belle Époque hotels, the sweeping Grande Plage, and the Rocher de la Vierge sea stack still carry that elegant legacy. The covered market, Les Halles, on Rue Victor Hugo is an outstanding morning food market: local oysters, Basque cheeses, jambon de Bayonne, and gâteau Basque are the highlights. The Musée de la Mer occupies a 1930s Art Deco building on the Rocher de la Vierge headland and houses a seal tank and Atlantic marine exhibits.
The morning is best spent in Biarritz: walk the coastal path from Grande Plage south to the Rocher de la Vierge, browse Les Halles, and explore the old Vieux Port fishing quarter. Taking the train 17 kilometres south to Saint-Jean-de-Luz in the afternoon makes an efficient two-town itinerary.
Saint-Jean-de-Luz is arguably the more atmospheric of the two. The historic centre clusters around the harbour and the church of Saint-Jean-Baptiste, where Louis XIV married the Infanta of Spain in 1660. Traditional Basque architecture — whitewashed facades with red and green shutters — and the town's strong traditions in chocolate making and gâteau Basque give it a distinctive identity. Maison Adam (founded 1660) and Maison Pariès are the most celebrated patisseries. The return train to San Sebastián from Saint-Jean-de-Luz runs frequently.

Tips for visiting
- Take EuskoTren from San Sebastián's Amara station to Hendaye, then a French TER to Biarritz — more scenic than driving and avoids cross-border parking complications.
- Les Halles market in Biarritz closes in the early afternoon; arrive by 10:30 to catch it at its best before the stalls begin to wind down.
- Bring some cash in euros — smaller market stalls and traditional shops in both towns may not accept foreign bank cards reliably.
- Saint-Jean-de-Luz is 15 minutes from Biarritz by TER train, making a two-town day itinerary efficient without a car.
- Beach parking in Biarritz is expensive and limited in summer; the train option is significantly more straightforward.
When to visit
June and September offer ideal Atlantic coast conditions — pleasant temperatures without the peak August crowds. The market and coastal path are best enjoyed in the morning before midday heat and tourism traffic build. July and August bring surf festivals and heavy visitor numbers.
Frequently asked questions
Do visitors need a passport to cross into France from Spain?
EU and Schengen-area citizens can cross freely without showing a passport. Travellers on non-EU documents should carry their passport as spot checks occur at the French border, particularly on the road crossing.
Is Biarritz expensive compared to San Sebastián?
Restaurant and cafe prices in Biarritz are generally slightly higher, reflecting French price levels. The Les Halles market is an affordable option for lunch; supermarkets near the market are competitively priced.
Can Biarritz and Saint-Jean-de-Luz both be visited in a single day?
Yes. A morning in Biarritz followed by an afternoon in Saint-Jean-de-Luz is a comfortable and popular itinerary; a 15-minute TER train journey connects the two towns throughout the day.
What is gâteau Basque and where can it be tried?
Gâteau Basque is a traditional pastry of the French Basque Country, filled with either cherry preserve or pastry cream inside a shortcrust shell. Maison Adam in Saint-Jean-de-Luz (founded 1660) is the most historic producer; Biarritz's market stalls also sell it.
