Basque Country Bike Tour: Exploring the Coastline and Forests in Northern Spain

You want a cycling holiday that offers everything. You want the salt air of the Atlantic on your face in the morning and the deep, quiet scent of an ancient beech forest by the afternoon. You want world-class cuisine that fuels your climbs and descents that make you feel like a kid again.

Welcome to the Basque Country.

We’ve just launched our newest 6-day self-guided Basque Country bike tour, and it’s a journey of contrasts. It’s a carefully curated loop that takes you from the glamorous crescent bay of San Sebastián into the rugged heart of the Navarre mountains and back again. We’ve handled the logistics, the route mapping, and the gear. All you have to do is enjoy the ride!

Why the Basque Country?

Planning a multi-day trip in a foreign country is a massive headache. You spend hours squinting at Google Maps, wondering if that "road" is actually a goat path or a high-speed motorway. You worry about luggage transfers and whether your rental bike will hold up on a mountain pass.

We get it. We’re cyclists too. That’s why we designed this tour to eliminate the "what-ifs." This route uses a mix of quiet mountain backroads and legendary "Vias Verdes" (Greenways): disused railway lines converted into smooth, car-free cycling paths. It’s the perfect balance of adventure and accessibility.

The Journey Begins: San Sebastián to the Mountains

Your adventure kicks off in San Sebastián (Donostia). It’s one of the most beautiful coastal towns in Spain, famous for its golden beaches and more Michelin stars per square meter than almost anywhere else on Earth. But you’re not here just to eat: though the pintxos are a mandatory part of the experience.

After loading up your rental bike, you’ll head inland. The transition is almost immediate. Within miles, the urban buzz fades, replaced by the rhythmic hum of tires on pavement. You’ll leave the coast behind and follow the Oria River valley, climbing gently toward the mountains of Navarre, and on your way to experience a remarkable blend of dramatic landscapes, quiet rural roads, and genuinely vibrant coastal culture.

As ever, the beauty of a self-guided cycling holiday is the freedom. If you see a tiny bakery in a stone-walled village, you are free to stop without holding up the group. If you want to take twenty photos of a medieval bridge, take them! You aren't chasing the ride leader; you’re chasing the horizon.

Into the Green: The Vias Verdes

The centerpiece of the inland leg is the Plazaola Greenway. This is cycling at its most serene. Imagine miles of shaded paths winding through lush, emerald-green forests. Because this was once a railway line, the gradients are never punishing. It’s a steady, manageable climb that rewards you with incredible views without burning out your quads.

The coolest part? Probably the tunnels. a series of atmospheric tunnels carved through the hills, including the impressive Uitzi Tunnel, the longest greenway tunnel in Europe!

The old train tunnels are lit and well-maintained, providing a damp, cool thrill as you transition from one valley to the next. You’ll feel like you’ve traveled back in time as you pass old station houses and remote farmsteads where life moves at the pace of the seasons.

As the route continues through the rolling farmland and traditional villages of northern Navarre, cyclists experience the authentic Basque countryside while tracing sections of the famous EuroVelo 1 Atlantic Route.

From the mountains, the tour gradually descends along the tranquil Bidasoa Greenway, following the river through lush valleys toward the coast. The scenery shifts once again as riders reach the colorful fishing town of Hondarribia and explore the nearby French Basque coast on a loop to the charming seaside town of Saint-Jean-de-Luz.

For those who want a bit more power on the climbs, we highly recommend consider an electric bike. It levels the playing field, letting you focus on the scenery rather than the sweat.

Crossing Borders and Climbing Cliffs

As you loop back toward the Atlantic, the landscape shifts again. You’ll tackle some of the most iconic cycling terrain in Northern Spain. This includes quiet mountain roads that snake through the Aralar Range, offering panoramic views of limestone peaks and deep valleys.

Eventually, the scent of the sea returns. You’ll reach the dramatic Atlantic cliffs near the border with France. One of the highlights is Mount Jaizkibel. If you follow professional cycling, you’ll recognize this name: it’s a staple of the Clásica de San Sebastián.

The climb is steady, the road surface is excellent, and the views over the Bay of Biscay are, quite frankly, spectacular and an unforgettable way to finish this  scenic cycling adventure!

The Gear That Gets You There

A great tour is only as good as the bike beneath you. We take our bike hire in Spain seriously. For the Basque Country, you need versatility. You need a bike that is fast on the tarmac but stable on the hard-packed gravel of the Greenways.

Your tour includes comfortable and reliable gravel bikes and robust touring setups. Every bike comes fully serviced and equipped with the bicycle accessories you need: panniers, repair kits, and our detailed turn-by-turn routes that ensure your best riding experience.

We’ve spent years figuring out which gear works and which gear fails. When you book with us, you’re getting the benefit of all those miles. We don’t just give you a bike; we give you a machine we’d be happy to ride ourselves.

Authentic Basque Culture

Between the rides, you’ll be staying in hand-picked accommodations that reflect the local character. Think historic stone houses with wooden balconies, tucked away in narrow village streets.

You’ll experience the unique Basque culture firsthand. It’s a place with its own language, its own traditions, and a fierce pride in its land. You’ll see it in the architecture, taste it in the local Txakoli wine (a slightly sparkling white wine poured from a height), and feel it in the quiet dignity of the mountain villages.

Cycling allows you to be a participant in the landscape, not just an observer. When you roll into a village square on a bike, you’re met with a different kind of welcome. You’ve earned your arrival.

Ready to Ride?

The Basque Country is waiting. This 6-day tour is designed for those who want to see the "hidden" Spain: the one away from the tourist traps and crowded resorts. It’s for the riders who love a good climb, a long descent, and a cold beer at the end of the day.

Don't spend another year talking about "the big trip." We’ve done the hard work of finding the best roads and the most scenic stops. All you need to do is show up and pedal.
