Cycling day trip from Donostia / San Sebastian to Bilbao

Ready for an epic ride in the Basque Country? This route takes you from the beautiful seaside charm of Donostia / San Sebastian to the vibrant, culture-packed city of Bilbao. You’ll cover roughly 150 km, so it’s a solid day (or scenic two-day) adventure!

Expect lots of up and down—over 3,400 meters of climbing—so get those legs in shape! You’ll pass rolling hills, lush forests, and classic Basque villages, all while winding along mostly quiet roads and some lovely dedicated cycleways. Surfaces are a mix: mostly paved, with a splash of gravel and concrete here and there, perfect for a sturdy road or gravel bike.

San Sebastian boasts world-famous pintxos and a dreamy bay, while Bilbao dazzles with its famous Guggenheim Museum and riverside vibe. Along the way, savor glimpses of the Cantabrian Sea, mountain vistas, and, of course, some legendary Basque hospitality.

Take your time, enjoy the stops, and bring your camera—this ride is as much about the journey as the destination!
