Adventure brief
Along the old Plazaola: Biking the Leizaran Valley from Andoain
S • BTT Adultos is a bike-rental and guided-route experience based in Andoain that uses the old Plazaola railway bed—today a vía verde—to carry riders into the Leizaran valley, revealing tunnels, prehistoric monuments and traces of past industry amid pastoral landscape.
At the heart of Euskadi's lush green expanse lies the Leizaran valley, a corridor of natural beauty and quiet history.

Their S • BTT Adultos trip caters to adults eager for an active day on two wheels, delivering a uniquely immersive cycling experience free from the usual road traffic and uphill struggles.
The route follows the gentle gradients of the old railway line, threading through dim, atmospheric tunnels and crossing rustic stone viaducts. Along the way, riders encounter prehistoric monuments, reminders of the ancient communities that once inhabited these woods. The valley’s geology reveals deep layers of sedimentary rock, shaped by glacial epochs, while the forest shelters native wildlife like roe deer and golden eagles.
Leitzaran Bisitarien Etxea stands out not only for its well-maintained bike rentals but also for its deep local knowledge and personalized service. Staff are passionate about introducing visitors to this region’s outdoor culture without overwhelming them, making it an accessible adventure even for those new to mountain biking.
