After the Biarritz Marathon: San Sebastián

The Route: Biarritz → San Sebastián / Donostia Logistics: Coach services (FlixBus and Alsa both run the route), roughly 35 minutes each way. Short enough that the border crossing barely registers, long enough to justify two full nights on the other side. Marathon Month: April Duration: 2 nights

Biarritz ──(≈35 mins coach, FlixBus/Alsa)──> San Sebastián / Donostia

The Marathon International de Biarritz – Pays Basque finishes on French Basque soil, but the same Basque coastline continues, largely uninterrupted in language and food culture, across the Spanish border to San Sebastián, known locally as Donostia. The trip crosses no meaningful logistical hurdle: France and Spain share the Schengen area, so there is no passport control to plan around, and the euro is the currency on both sides, so nothing needs changing at the border beyond a mobile data roaming check. April on this stretch of Spanish coast runs the same cool, changeable Atlantic pattern as Biarritz itself: expect a mix of sun and cloud rather than a guaranteed beach week, useful for a city built as much around eating as around sand.

Multiple daily coach departures run the roughly 35-minute route between Biarritz and San Sebastián, operated by both FlixBus and Alsa. Confirm the current departure point in central Biarritz when booking, since operators can vary the exact stop, and check timetables at flixbus.co.uk or alsa.com before travelling.

Nights One and Two: San Sebastián

San Sebastián grew up around a natural harbour on the Bay of Biscay, and its identity is inseparable from La Concha, the shell-shaped bay that gives the city one of the most complete urban beach settings in Europe, framed by Monte Igueldo to the west and Monte Urgull to the east. The Paseo de La Concha, the promenade that runs the full curve of the bay, is flat, wide and paved for its entire length, easily walkable at a slow post-marathon pace with no gradient and no unavoidable steps; benches and shaded sections appear throughout, and the walk from one end to the other covers a little under three kilometres.

The Parte Vieja, the old town tucked between Monte Urgull and the harbour, is the city's pintxos district and worth treating as an eating itinerary rather than a sightseeing one: narrow, mostly level streets lined with bars, each specialising in two or three signature small plates rather than a full menu. Bar Nestor, on Calle Pescadería, is known specifically for its tortilla, made in two batches a day and typically gone within minutes of each one appearing on the counter, so timing matters more here than at most pintxos bars; arrive close to opening if a slice matters to the plan. A short flight of steps up Monte Urgull leads to the Castillo de la Mota and sweeping views back over the bay, worth attempting on the second day once legs have loosened rather than straight off the coach.

The Museo San Telmo, housed partly in a former Dominican convent, covers Basque history and culture and gives a substantial indoor option if the weather turns; entry runs to a modest fee, with reduced or free hours on some days that are worth checking before visiting.

For dinner beyond the pintxos crawl, La Cuchara de San Telmo, a small, standing-room bar in the old town, is well regarded for modern, hot pintxos rather than the classic cold-topped bread style, a useful contrast on a second night after a first spent on tortilla and classics.

Where to stay: Hotel Maria Cristina, a Belle Époque landmark on the banks of the Urumea river close to the old town, puts a guest within flat walking distance of both La Concha and the Parte Vieja, and its riverside setting away from the beachfront crowds suits a quieter recovery stay. For a more central, less formal option directly facing the bay, look to one of the smaller hotels along the Paseo de La Concha itself, which trade some of the Maria Cristina's grandeur for a shorter walk to the water.

Getting Home

Return to Biarritz Pays Basque Airport (BIQ) by retracing the roughly 35-minute coach journey back to Biarritz, allowing time for the connection from the coach stop to the airport (around 4 kilometres from central Biarritz, five minutes by taxi or the Txik Txak line 11 bus). San Sebastián also has its own small regional airport (EAS), with a more limited route network than Biarritz, and Bilbao Airport (BIO), around an hour and a half further west, offers substantially more international connections if the return journey is being planned independently of the outbound one. Check current schedules at flixbus.co.uk or alsa.com before booking the return leg.
