San Sebastián isn’t just about pintxos, the beach and the city.
What many people don’t realise is that just a few kilometres away, you can enjoy hiking trails that reconnect you with nature and make you feel far away from it all — without actually going too far.
If you enjoy walking and love a mix of mountains and sea, this is for you.
Camino de Santiago: from San Sebastián to Orio
This route is part of the northern section of the Camino de Santiago, but you don’t need a pilgrim’s backpack or religious intentions to enjoy it.
The stretch between San Sebastián and Orio is about 16 km, with ascents and descents that you’ll feel in your legs — and also in your heart, thanks to the emotions the trail gives you.
The path begins in the Gros neighbourhood, climbs Mount Ulía and quickly leaves the city noise behind.
You’ll pass cliffs, forests and rural stretches where you’ll encounter more sheep than cars.
It’s not just beautiful: it’s the kind of trail that leaves you with the sense of having done something truly different.
Do take water and snacks, as there aren’t many places to stock up until you reach Orio.
Once in Orio, it’s best to stop for a bite to eat and return by train or bus. If you want to make it a circular route, be prepared for six to seven hours of hiking if you walk back to San Sebastián.
Hiking Mount Jaizkibel from Pasaia
If you’re looking for something more challenging, aim for Jaizkibel.
To reach the starting point, simply take a bus or a boat to Pasaia (the sea journey from Donosti is an experience in itself).
From there, the trail gradually climbs along stone and dirt paths to the summit of this imposing mountain.
It’s a full-day plan if you take it easy.
You’ll come across old bunkers, dramatic cliffs and, on clear days, views across to France.
What really makes this hike special is how wild it feels despite being so close to San Sebastián.
Tip: wear good footwear, especially if it has rained. The stones can be slippery, and it’s not terrain for improvising. A light windbreaker is also useful, even in summer.
Circular Route around Mount Igueldo
Everyone knows Igueldo for its amusement park and the postcard views of the bay, but few take the circular hiking trail that goes beyond the famous viewpoint.
This walk is ideal if you’re short on time or don’t want anything too demanding, but still fancy a decent workout.
The route starts in Ondarreta, climbs along the old lighthouse path and loops around the hillside.
You’ll find shady sections, more open stretches, and at the end you can stop at a bar to refuel. It’s around 8–10 km depending on your path, suitable for those with average fitness.
It’s not about training, but about enjoying a pleasant hike without straying far from the city.
Do it in the afternoon and you can end by watching the sunset from above — a totally different vibe to the famous La Concha sunset.
Much calmer, and often without the crowds.
The Talaia Clifftop Trail (Hondarribia to Pasaia)
This is a serious hike.
The Talaia Trail links Hondarribia with Pasaia and follows the Gipuzkoan coastline like a balcony hanging over the sea. It isn’t circular, so you’ll need to arrange transport or plan a bus/car return.
The appeal of this route is its mix of steady climbs and downhill stretches that leave you sore the next day — but also thrilled to be part of the landscape.
You’ll see cliffs, narrow paths, meadows and moments when the sea feels just a couple of steps away.
The full hike is about 22 km, though you can split it into shorter sections. A particularly good one is Jaizkibel to Pasaia.
Do be prepared: there aren’t many water sources, phone signal is patchy, and in summer the sun is strong.
Hiking Mount Adarra from Besabi
If you prefer the greenery of the interior, Mount Adarra is a safe bet.
This hike isn’t very well known among tourists, but locals in Donosti value it highly as a medium-to-tough challenge close to the city.
The route starts from the Besabi farmhouse, which you can reach by car or taxi from San Sebastián.
From there, the trail begins steeply, heading into woodland before gradually gaining altitude and changing scenery.
At the summit, you don’t just get great views but also the feeling of having climbed a “real” mountain.
It’s not overly technical but does require reasonable fitness.
Ideal for those who want a more serious hike without travelling far.
And if you plan well, you can end the day with a hearty meal at one of the nearby farmhouses.
Tips for enjoying hiking around San Sebastián
- Plan ahead: although many routes are signposted, it’s wise to download the track or use an app like Komoot or Wikiloc.
- Pack light: a comfortable backpack, water, snacks and sun protection. In spring or autumn, take a light jacket in case the weather changes.
- Avoid peak hours: head out early to dodge the heat (in summer) and the larger groups that can crowd some sections.
- Don’t trust the weather: in the Basque Country, it can change quickly. Check the forecast but be ready for anything.
