The Route: Biarritz-la Négresse → Saint-Jean-de-Luz–Ciboure → Biarritz-la Négresse Logistics: TER train, 13-15 minutes each way. A single night is enough to see the port properly without rushing back for a Sunday-afternoon train. Marathon Month: April Duration: 1 night
Biarritz-la Négresse ──(13-15 mins TER)──> Saint-Jean-de-Luz–Ciboure ──(13-15 mins TER)──> Biarritz-la Négresse
The Marathon International de Biarritz – Pays Basque closes with roughly 6 kilometres along an exposed stretch of Atlantic coast, which means most finishers arrive back at Aguiléra having already had enough of open sea wind for one day. Saint-Jean-de-Luz offers the opposite: a bay closed off by two breakwaters, built after storms repeatedly wrecked the harbour in the seventeenth and eighteenth centuries, so the water inside barely moves even when the open Atlantic beyond it is working itself into a temper. April here runs cool and often damp, in line with the same Atlantic weather pattern that shapes race day in Biarritz, so this is a walking-and-eating trip rather than a beach one, with the sheltered bay a reliable spot for a slow paddle rather than a swim.
The train from Biarritz-la Négresse to Saint-Jean-de-Luz–Ciboure takes 13-15 minutes, with fares from around €3 one way. Services run regularly through the day; no advance booking is needed for a journey this short.
A Night in Saint-Jean-de-Luz
Saint-Jean-de-Luz built its fortune on Basque whaling and cod fishing, and later on corsairing against Spanish shipping, before Louis XIV's wedding to the Spanish infanta Maria Theresa in the town's Église Saint-Jean-Baptiste in 1660 gave it a second identity as a royal waypoint. Both histories are still legible in the old town's tight grid of half-timbered merchant houses.
The promenade around the bay is the primary recovery walk here: a flat, paved path running the full curve of the sheltered beach and harbour, easily three kilometres if followed end to end, with no gradient worth mentioning and benches at regular intervals. The working fishing harbour sits at the walk's northern end, where boats still land anchovy and tuna catches most mornings, and it is worth timing a stroll past there before midday to see the boats in rather than out.
The Maison Louis XIV, the merchant house where the king stayed for his wedding, is open to visitors for a few euros and gives an indoor option with genuine historical weight rather than generic period furniture, useful if the weather turns.
For dinner, Le Kaïku, a Michelin-recognised restaurant housed in one of the oldest buildings on the harbourfront, serves Basque coastal cooking built around the day's fish catch; it is the kind of place worth booking ahead rather than turning up to on a Saturday night in shoulder season. For something simpler, the covered and open-air stalls around Les Halles give a lower-key option for a plate of jambon de Bayonne and local cheese without committing to a full sitting.
Where to stay: Hôtel de la Plage, directly on the seafront facing the bay, puts a recovering runner within a flat two-minute walk of the water and the old town both, with sea-view rooms that make the most of the sheltered outlook. For a more central base closer to the harbour and the old town's restaurant streets, look to one of the smaller family-run hotels around Les Halles and the Place Louis XIV, which put dinner and the morning market within a few minutes' walk rather than a promenade stroll.
Getting Home
Return to Biarritz Pays Basque Airport (BIQ) via Biarritz-la Négresse: the train back from Saint-Jean-de-Luz–Ciboure takes 13-15 minutes, and the airport itself sits around 4 kilometres from central Biarritz, roughly five minutes by taxi or via the Txik Txak line 11 bus. Build in a connection buffer between the two legs rather than timing them back-to-back, since neither service runs to a fixed cross-platform schedule.
