The Train Track Trail Mountain Bike Ride – Private experience

A former railway line leads you out of San Sebastián and into the wooded Basque countryside, where the ride follows a river through old tunnels, quiet villages, and a long, gentle descent. The trail once carried iron from the mines toward the city. Today, it offers a calm way to see a side of the Basque Country that you will miss from the beach and pintxos bars.

I like two things right away: the private format means the guide can adjust the distance to your group, and the mostly flat trail makes this a real option for casual cyclists and families. Guides Borja and Kevin are praised for being friendly, encouraging, and good company, while the post-ride picnic gives the outing a proper Basque finish.

The main consideration is the price, $276.67 per person, which is a serious spend for a four-and-a-half-hour activity. You are paying for private transport, bikes, guiding, flexibility, and lunch, so the value is strongest for families or small groups who want an easy, fully arranged day outside the city.

Key details before you book

• An old railway becomes your cycling route: The trail runs about 25 kilometers through wooded valleys, tunnels, and small villages.
• The ride is tailored to your ability: Your guide decides how far to go with you, rather than forcing every group to complete the same distance.
• Leiza and Berastegi frame the outing: These are the named stops along the route and help place the ride in the rural Basque setting.
• A river stop can cool you down: After cycling, you may have time to swim in a river pool, depending on the day and group.
• The picnic is part of the experience: Expect a traditional Basque meal and drinks in a peaceful outdoor setting.
• City pickup keeps the morning simple: Pickup is offered from hotels, apartments, vacation rentals, and designated spots within San Sebastián.

Leaving San Sebastián for the Leiza trail

The day begins at 10:00 a.m. Pickup is available from your hotel, apartment, vacation rental, or an agreed location in San Sebastián. If you are staying outside the city, you cannot receive city pickup, but you can meet the group at the starting point.

That transfer matters. You do not need to find a rural trailhead, arrange a taxi with bike space, or work out the route yourself. Previous outings used a clean van, and the drive from San Sebastián to the starting area was described as quick and easy. Borja also uses the journey to answer questions about local life and the area, so the transfer becomes part of the introduction to the Basque countryside.

The route is associated with Leiza and Berastegi, two rural points in the wider trail area. The setting changes quickly from urban San Sebastián to thick woodland, river scenery, and small settlements. If your trip is focused only on the coast, this is a useful change of scene.

Your guide may be Borja or Kevin. Borja has guided families with children as young as eight, older riders, and groups looking for a more active outing. Kevin has also been praised for keeping up an easy conversation while explaining the countryside and life around San Sebastián. The exact guide should be confirmed when you book.

A railway line with an easy gradient

The old railway is the heart of the ride. It was built to move iron from the mines toward San Sebastián, but the route now functions as a peaceful cycling trail. You ride beside the river, through the woods, and into a series of timeworn tunnels cut into the rock.

The route is about 25 kilometers, with some descriptions placing the full ride closer to 26 kilometers. The key point is not the exact number. The trail is generally downhill or gently sloping, with no big hills and a mostly flat feel. One group of older riders completed the ride at a relaxed pace, while families used the guide’s flexibility to keep the outing comfortable for children.

That makes this less of a hard-core mountain-bike test and more of an off-road countryside ride. You still need to handle a bike on a trail, and some sections may feel challenging if you are not used to uneven ground. But the gentle railway gradient removes the steep climbs that can turn a pleasant family ride into a slog.

The tunnels are a memorable part of the route. They are semi-dark, cool, and more atmospheric than an ordinary bike path. You move from sunlit woodland into rock and shadow, then back into the open valley. A working bicycle light is not mentioned in the tour details, so ask the operator what equipment is supplied if tunnels concern you.

How the guide shapes the ride

This is a private activity, so only your group participates. That is the feature that most affects the feel of the morning. A couple can keep a steady pace, a family can stop more often, and a stronger group can ride farther if time and energy allow.

The guide tailors the distance to your level. You do not have to treat the advertised 25 kilometers as a fixed exam. That is especially useful if one person in your party is nervous, if children are riding, or if you want to save energy for the picnic and river stop.

The guide’s role goes beyond leading from the front. Borja has been praised for encouraging an eight-year-old who felt unsure on some sections, helping her gain confidence without turning the ride into a lesson. He has also taken photos and videos for groups, although you should confirm whether that is part of your own outing rather than assume it is guaranteed.

The guides also add local context. Questions about the area, local life, the railway, and the Basque countryside can be part of the conversation. This gives the route a human connection that you will not get by renting a bike and following a map alone.

Berastegi, tunnels, and river views

As you ride toward Berastegi, the appeal is the steady rhythm of the old railway. The trail winds beside the river, with trees overhead and stretches of quiet broken by the sound of water and the bicycle tires. Little villages appear along the way, offering a sense of how the route connects the rural valley.

Do not expect grand viewpoints at every turn. This is a wooded ride, not a high mountain route. The reward is the peaceful setting, the changing light in the tunnels, and the sense of moving through a former industrial corridor that has found a gentler second life.

There are breather spots along the trail. Your guide can adjust the pace and use these pauses to explain what you are seeing or simply let the group catch its breath. Families should appreciate this, since children may want stops even when adults feel ready to continue.

The river is another practical advantage in warmer weather. At the end of the ride, you may have a chance to cool off in a swimming hole. This is not presented as a guaranteed formal swimming session, so bring a swimsuit only if you are comfortable carrying it and confirm the plan with the operator.

The picnic that completes the morning

After the cycling, the group finishes with a traditional Basque picnic in a scenic setting. Food and drinks have been singled out as a strong part of the experience, and they are more than a minor snack after a long ride.

The meal changes the outing from a simple bike rental into a fuller cultural day. You get time to sit, eat, and take in the valley rather than rushing back to the city. For families, this also creates a natural reward after the effort of the ride.

One outing included a river swim before lunch, with the guide and children joining in. Another group combined the cycling with a visit to a cider house, where they learned about the local tradition, caught cider from the barrel, and ate a substantial meal. The standard description for this experience promises a picnic, not a cider-house visit, so do not book expecting the cider stop unless the operator has arranged it separately.

The food is described as traditional Basque fare, but no fixed menu is provided. If you have allergies, dietary restrictions, or strong food preferences, ask before booking. The tour is private, which may make adjustments easier, but they should still be agreed in advance.

Is $276.67 per person good value?

At $276.67 per person, this is not the cheapest way to ride a bike near San Sebastián. A self-guided rental would cost less, assuming you could find the equipment, transport, and route on your own.

The comparison is not quite fair, though. The fee includes a private experience, city pickup when applicable, transport to the rural trail, bicycles, safety equipment, a guide, route planning, flexibility in distance, and a picnic. You are also paying to avoid the practical work of getting a group to a remote trailhead.

The value improves with four or more people, especially if you have children or mixed cycling abilities. A private guide can make the outing work for the least confident rider without forcing the stronger riders to sit through a rigid beginner tour. Group discounts may be available, so ask about them before paying.

For a couple, the cost is harder to justify unless the private attention, local conversation, and picnic are central to what you want. For a family that wants one organized day outside San Sebastián, the price may compare well with arranging several separate services.

The experience is booked an average of 53 days ahead, which suggests you should not leave it until the final morning of your trip, especially if your dates are fixed.

Who will enjoy this ride most?

This ride suits you if you want exercise without a punishing climb. It works especially well for families, casual cyclists, and groups who prefer countryside to city sightseeing for half a day.

Children have completed the ride, including an eight-year-old who needed encouragement on some sections. The description says most people can participate, but you should still be comfortable riding a bicycle and following a trail. The activity is not described as accessible for wheelchair users or people unable to cycle.

It is also a good fit for older riders who want an active outing at a controlled pace. The flexible distance and gentle gradient make it possible to ride for a couple of hours without treating the route as a race.

You may want another activity if you are looking for steep technical riding, a fast mountain-bike workout, or a dramatic high-altitude route. This is an easygoing off-road ride through a valley, not an extreme sports session.

Timing, weather, and practical planning

The scheduled start is 10:00 a.m., and the complete experience lasts about four hours and 30 minutes. That leaves time to return to San Sebastián for an afternoon at the beach, as one family did, though the actual finish may vary with riding pace and stops.

Wear clothes you can cycle in and shoes suitable for a bike trail. Carry water unless the provider tells you otherwise. If you hope to swim, bring suitable clothing, but confirm whether the river stop will be included on your date.

The experience depends on good weather. If poor weather causes cancellation, you will be offered another date or a full refund. You can also cancel for a full refund up to 24 hours before the local start time. Changes or cancellations inside that 24-hour window are not accepted.

Confirmation is sent within 48 hours of booking, subject to availability. Pickup is limited to San Sebastián itself, so plan to meet at the starting point if you are staying elsewhere.

Should you book the Train Track Trail?

I would book this if you want a personal, active escape from San Sebastián and your group values scenery, local conversation, and an unrushed meal more than a low price. The former railway, dark tunnels, river sections, and flexible distance give the ride real character.

The best match is a family or small group with mixed abilities. Ask about the guide, the expected distance, swimming conditions, dietary needs, and whether your date includes the picnic format described here.

Skip it if you want a demanding mountain-bike challenge or if $276.67 per person feels too high for a half-day outing. For everyone else, this is a well-rounded way to trade the city and coast for the quieter Basque countryside, with enough structure to make the day easy and enough flexibility to keep it enjoyable.
