Bear Trail by bike, downhill from Entrago, 45 minutes from Oviedo

The Senda del Oso (Bear Trail) is the greenway of the old mining railway that climbed from Tuñón towards Proaza and Teverga, among gorges, bridges and tunnels cut into the rock. What has made it so popular is the gradient: seen from the top, it is a gentle, continuous descent, so it can be done with children or if you are not used to riding a bike. It is about 45 minutes from Oviedo.

Two ways to organise it

With Centro BTT Valles del Oso, you park at Tuñón, kilometre 0, try the bike and they take you up by van to Entrago, kilometre 20. You ride down for about two and a half hours and reach your car, without waiting for a pick-up. The vans go up at 10:00, 11:15, 12:30, 14:00 and 15:00. With TeverAstur, you park at Entrago, at the top, pick up the bike there and ride 16 km down to the Buyera recreation area, in two or three hours; at the end you call and a van takes you back up, continuously from 13:00. TeverAstur also offers 26 and 46 km routes for those who want to pedal more.

Prices

At Valles del Oso, the 2026 season sets €18 for an adult bike independently and €15 for a child's; the descent with transfer, €28 per adult with a minimum of two, and €25 for a child's bike or the semi-tandem. The e-bike independently costs €50. It includes helmet, repair kit and assistance on the trail. TeverAstur shows its rates in the online booking when you choose date and bike.

With children and with a dog

Both companies have children's bikes, seats, semi-tandems and trailers. Valles del Oso hires dog trailers for dogs up to 25 kg; TeverAstur lets a large dog run alongside with a harness, hires trailers for those up to 12 kg and takes them in the van. Always on a lead.
