Coastal Mountain Bike Tour on Mount Ulia — San Sebastián Small-Group Ride
Ride from La Concha’s promenade up through forested singletrack to the ridgeline of Mount Ulia, then descend to the fishing harbor at Pasaia. This small-group mountain bike tour mixes coastal views, short technical sections and an easy urban return.
The Experience
Before You Go
Helmet provided — still bring your own if preferred
Helmets are supplied but regular riders often bring a familiar helmet for fit and comfort.
Expect mixed surfaces
Be ready to switch between pavement, compact dirt and rocky singletrack; tires with light tread work best.
Hydrate and time your ride
Start mid-morning to avoid strongest coastal winds and bring extra water—guides hand out bottled water but you’ll sweat on climbs.
Watch for coastal wind and traffic
Exposed ridgelines can be gusty and the descent toward Pasaia uses narrow roads—stay alert on turns and when re-entering bike lanes.
