Bike hire in Tuñón, kilometre 0 of the Senda del Oso: independently or with a van transfer to Entrago to ride 20 km gently downhill back to your car.

The Centro BTT Valles del Oso hires out bikes in Tuñón, in the municipality of Santo Adriano, where the Senda del Oso begins, the greenway on the former mining railway that climbs towards Proaza, Teverga and Quirós. It has mountain bikes, leisure bikes, electric bikes, gravel bikes, children's bikes, tandems, tricycles, and seats and trailers for babies and for dogs.

## Two ways to do the trail

Independently: you collect the bike at Tuñón and go out and back at your own pace. With transfer: you leave the car at Tuñón, they take you up by van to Entrago, at kilometre 20, and you ride gently downhill for about two and a half hours back to the car, with no waiting for pick-up. Van departures are at 10:00, 11:15, 12:30, 14:00 and 15:00.

## 2026 season prices

Independently, an adult bike costs €18 and a child's bike up to 24 inches, €15; the electric, €50; the gravel, €35; the tandem, €40. The descent with transfer costs €28 per adult, with a minimum of two people, and €25 for a child's bike or half-tandem. They include helmet, repair kit and assistance on the trail. Prices may change without notice.

## Winter

From December to mid-March it opens only at weekends and on public holidays, weather permitting. In high season booking is almost essential to secure a place on the van.
