min by bus
Oviedo ↔ Entrago
By car, RENFE train or ALSA bus. Oviedo is the nearest regional transport hub.
Autos Bimenes (Pullmans Llaneza) regular line. About 55 min. 4 stops along the trail.
You cover the 22 km from Entrago to Tuñón downhill (−200 m). 5-6 h with stops. No tough gradients.
Same service back. Check timetables in advance — the bus doesn't run every hour. Plan with some buffer.
With a stroller
Yes, you can do it on foot with a stroller — but only all-terrain ones. Small-wheel urban strollers get stuck on the gravel surface.
30 cm wheels with suspension on all 4. Holds steady on loose ground without bouncing.
Fixed front wheel, all-terrain. Stable on gravel and loose stones.
Pneumatic 30 cm wheels, off-road. Built for exactly this kind of surface.
Any jogger with pneumatic wheels ≥ 30 cm and suspension works.
These struggle
When in doubt, check the wheel: if it's hard plastic or under 25 cm, better stick to the Buyera → Enclosure section (800 m, partly paved).
