Starting Point: Close to La Concha Beach
The adventure kicks off just 50 meters from La Concha Beach, arguably the most famous and photogenic stretch in San Sebastián. Meeting at Marina Kalea, you’ll be greeted by friendly staff who equip you with everything needed, from bikes to helmets. This early proximity to the beach is perfect for travelers arriving in town, making it easy to combine with a beach day or stroll beforehand.
The Urban Ride: First 2 Kilometers
The tour begins with an easy bike ride through San Sebastián’s charming streets, offering a chance to appreciate the city’s blend of art nouveau architecture and lively atmosphere. The distance is short, allowing everyone to settle into the rhythm and enjoy the views of the bay and bustling promenades. It’s a gentle warm-up before heading into more natural landscapes.
Leaving the City: Ascending Mount Ulia
After about 2 km, the scenery shifts as you leave behind the city’s hustle. The climb up Mount Ulia begins, offering stunning vistas over the coastline. The ascent isn’t overly steep, but it’s enough to give a sense of adventure — especially if you’re not used to mountain biking. The trail weaves through lush forests and coastal trails, all adaptable to your skill level.
According to reviews, parts of the trail are quite challenging for some, emphasizing the importance of moderate physical fitness and some off-road biking experience. The terrain varies, with some single tracks that will appeal to those craving a bit of adrenaline, and other softer paths for less experienced riders.
Monte Ulia: The Heart of the Ride
The ride across Mount Ulia lasts about an hour, during which you’ll enjoy spectacular views of the coast and perhaps spot local wildlife or seabirds. The trail is described as varied terrain — some single tracks, some broader forest paths. This mix keeps the ride interesting and engaging.
One reviewer remarked, “Fabulous e-bike ride with lovely young guide Arti on single tracks in the hills above San Sebastián.” This suggests that guides are knowledgeable and friendly, adding a layer of reassurance if you’re new to mountain biking.
The Descent to Pasaia Bay
After reaching the summit, the tour takes you down towards Pasaia Bay, a picturesque fishing village known for its traditional boats and lively harbor. The stop here lasts around 20 minutes, perfect for snapping photos and soaking in the views. As one reviewer noted, “On our way down we stopped at the iconic Pasaia Bay,” highlighting how special this spot is to experience.
Returning via Bike Lanes
The final part of the tour involves a bike lane ride back into San Sebastián, making the return safe and comfortable. The transition from trail to urban bike lanes is seamless, giving you a chance to reflect on the ride while cruising back into the city.
What’s Included and What to Consider

The tour price of $103.03 per person covers use of a bike, helmet, and bottled water — a practical package that emphasizes comfort and safety. Since lunch is not included, you might want to bring snacks or plan for a meal afterward at one of San Sebastián’s renowned pintxos bars.
The small group size (up to 8 travelers) ensures a more personalized experience, with attentive guides who can adapt the route based on your comfort level. The activity is advertised as suitable for those with moderate physical fitness, so it’s not a casual ride for everyone. As some reviews pointed out, parts of the ride can be quite challenging, so some prior off-road biking experience is recommended.
Meeting and Ending Points
Starting at Marina Kalea, 9, the tour ends back at the same spot, making logistics straightforward. It’s near public transportation, so reaching the meeting point is simple whether you’re staying in town or arriving by train.
Weather and Cancellation Policy
Weather can impact the tour, as it requires good conditions. If canceled due to poor weather, you’ll be offered a different date or a full refund. Cancelations are free if made at least 24 hours in advance, which is helpful for travelers planning ahead.

One traveler remarked, “We had a good time. The guide was super nice, and the bikes were very well maintained.” This indicates a smooth ride, with attention to safety and comfort.
