No commitment · We design it with you
A valley that still remembers the bears.
Why it stands out
- 01
Almost flat
Following a railway track, the slope is minimal. Children, grandparents and anyone who hasn't been on a bike for years can enjoy it without struggling.
- 02
Truth tunnels
They aren’t just for show: you cross real mine tunnels dug into the rock, lit up where the temperature drops suddenly. Little ones especially love that part.
- 03
Bears with a cause
The enclosure of the Asturias Bear Foundation is not a zoo: it’s a conservation center for the Cantabrian brown bear. Visiting it is understanding why this valley protects its wildlife.
- 04
Logistics solved.
The shuttle service returns you to the starting point without having to pedal back. You go downhill, and the car is where you left it.
Who it fits
It’s not a good fit if you're looking for physical challenge, kilometers of uphill climbs or adrenaline: there are no steep slopes or technical excitement here. This route is for enjoying the scenery, not training.
