The Y shape
How the trail is divided
The Bear Trail is not a linear route. On the map it draws a Y: a common trunk that starts in Tuñón, climbs to the Caranga junction and there branches into two different valleys (Teverga and Quirós).
This structure is a direct consequence of the original rail layout — the mining train collected coal from both valleys and brought it together at Caranga on its way to Trubia.
Today you can ride just one section, two sections combined or the full Y (36 km), but the most common choice is Entrago → Buyera (18 km downhill) with return transfer.

This is the star section. It concentrates the three most photographed landmarks of the whole trail: the Molina enclosure (around the middle), the Peñas Juntas gorge (limestone walls almost touching) and the long tunnels of the old railway — including the longest on the trail (300 m).
Best
Maximum density of highlights per kilometre. If you only do one section, choose this one.
Worst
The busiest. In July-August and Easter there are groups every few minutes.
How to do it
- By bike from Buyera to Tuñón: 45 min – 1 h at a relaxed pace
- On foot from Buyera to Proaza (6 km): ~1.5 h with the family
- Combined with the Molina enclosure (add 30 min visit)

Questions about the sections
Quick answers to what people ask before choosing a section.
Need help?
+34 644 199 430 1. Which section of the Bear Trail is the prettiest?
The Tuñón → Caranga section (main trunk) is the most popular and landmark-packed: Molina enclosure, Peñas Juntas and the longest tunnels. For a more dramatic landscape, the Valdecerezales gorge (Teverga branch) is the most photographically spectacular. There is no objective "prettiest section" — each has its own appeal.
2. What is the Bear Trail short route?
The standard short route is Entrago → Buyera: 18 downhill km that combine the Teverga branch + part of the trunk up to the Molina enclosure. It takes 2 h by bike. It's the most booked route among tourist groups.
3. How many km is the full Y?
36 km. The Tuñón-Caranga trunk is 11 km, the Teverga branch (Caranga-Entrago) is 11 km and the Quirós branch (Caranga-Santa Marina) is 14 km. The most popular tourist route is the 22 downhill km of Entrago → Tuñón, combining 2 sections.
4. Is any section steeper?
The Teverga branch (Caranga → Entrago) uphill has +170 m cumulative, the most demanding. Downhill it's the most enjoyable. The other two sections are practically flat.
5. Which section is best with a wheelchair or pram?
The main trunk (Tuñón → Caranga) is the best: compacted gravel surface, 1.5% gradient, with adapted car parks in Tuñón and Proaza. The branches are rideable but with more uneven parts.
6. Can I do just one section and come back by public transport?
Yes. Autos Bimenes (Pullmans Llaneza) run lines from Oviedo to various points on the trail. Useful if you do a single section and want to combine bike out + bus back. If you rent with us, the return transfer from Buyera is included.
