My tip“Book bikes (and child seats) in advance with the rental companies in Entrago. Bears show up most in the morning and at feeding time, and bring your lunch as services are limited.”
An old railway converted into a level green path across the valleys of Asturias, with tunnels, a river and bridges. It passes through a reserve where you can see brown bears up close. The best option is to rent bicycles and start from Entrago (about 20 km, gently downhill), with a bus return service. Ideal for families of all ages.
Easy to reach, needs a car
By car to Entrago or Proaza. A paved, almost level greenway suitable for bicycles, strollers and older people; the bear enclosure is about 1–2 km from Proaza. A few cafés in the villages, and patchy signal.
