All dogs welcome
How to ride the Bear Trail with your dog step by step: pet-friendly trailers up to 30 kg, water fountains at every stop, shaded areas and what to do with the livestock mastiffs you may meet along the way.
Can I bring my dog?Dog-friendly
Yes, no problem. It's a greenway open to dogs year-round, provided they stay on the lead. There are no restrictions by breed, size or age — with the right kit it suits any canine profile.
Pet-friendly
No extra charge
Why it's ideal

Easy on the pads, no loose stones or hot tarmac.

Entrago, Proaza, Buyera and Tuñón. Wide spouts to drink easily.
Rest areas every few km
Shaded tables to stretch legs and take a break.
Things to keep in mind
Lead required the whole way
Fine up to €300 if off-lead. Current Asturian regulation.
Not allowed in Molina's enclosure
Protected wildlife area. See the next section.
Mind the livestock mastiffs
They're territorial. Full tips further down the page.
Dog trailers
The most comfortable option when your dog can't or won't run the full 18 km next to the bike. Your dog rides lying down and you pedal without pulling the lead.
Most popular
For dogs that tire after 3-4 km or aren't used to running long distances. Hitches to the rear axle of your bike.
Reference breeds: Border Collie, French Bulldog, Cocker, medium mixes
Front window so they can see the road.
22€/day
Big dogs
For big dogs who won't run the full 18 km. Some owners use it with 2 small dogs together.
Reference breeds: Labrador, Golden, young German Shepherd, large mixes
Same build as the standard, more room.
30€/day
For both trailers
Cash or Bizum when you pick up the kit at our shop in Entrago. Refunded in full if the trailer comes back clean and undamaged.
We handle the fur cleaning ourselves.

If they run next to the bike
Running 18 km downhill only makes sense if your dog is used to it. When in doubt, come with a trailer — you can pop the dog in if they tire and keep going.
Yes, we can run
Already runs 5+ km regularly with you.
Joints fully formed. Full development.
Border, Husky, mixes with good cardio.
Heat + running = heatstroke. Start early in summer.
Better with trailer
Only walks 20-30 min a day. Not trained.
Bulldog, Pug, Boxer. Breathing issues.
Joints still forming. Injury risk.
Over 25 °C or strong direct sun. Dangerous.
Must-have kit if they run: hands-free bungee lead with a waist belt. Stops yanks on the handlebar.
Dog-friendly on the route
Everything you need to know so you and your dog can stop comfortably. Always bring a collapsible water bowl in your backpack.
Molina's enclosure
Dogs aren't allowed at the enclosure viewpoint. It's a protected wildlife area run by the Fundación Oso de Asturias. Pets are forbidden to avoid stressing the captive bears.
But there are solutions:
One stays outside with the dog while the other sees Molina. The viewpoint takes 15-20 min and there's almost never a queue.
You can leave the dog in the trailer in the shade (if it's cool) for 15 min. Never in summer heat.
It's right by the trail, free access year-round. Proaza car park 5 min on foot. That way you enjoy both.
Livestock mastiffs
At several spots there's livestock guarded by Leonese or Cantabrian mastiffs — very big dogs (50-80 kg) whose job is to protect the flock. They're not naturally aggressive, but they are territorial.
Where they appear
Around Proaza
Sheep flocks in the pastures around the village.
Teverga branch · Caranga to Entrago
Mostly cattle, possible in high grazing season.
Tameza range (detours up high)
If you detour to Villanueva or climb to the mountain pastures.
The 4 golden rules
Never cross a flock with your dog. Keep at least 50 m and pass behind or along a wide side.
The mastiff reads fleeing as a threat. Walk or pedal calmly, no sudden pace changes.
They're territorial, not aggressive. They bark to warn you're near. Keep your dog close to you.
Stop and sit your dog. The mastiff wants to check who you are. Once identified, it walks away on its own.

Need help?
+34 644 199 430Yes. It's a greenway open to dogs year-round as long as they stay on the lead. The route is ideal: compacted gravel surface, forest shade most of the way, water fountains at every stop and rest areas with picnic tables.
Two sizes: standard up to 20 kg (€22/day) and XXL up to 30 kg (€30/day). Both with a single refundable deposit of €40. They include safety net, interior lead, front window and waterproof hood. The XXL has reinforced suspension.
Only if they're used to running long distances (5+ km regularly). We recommend a hands-free bungee lead with a waist belt. Not advisable for city dogs that only walk, brachycephalic breeds (Bulldog, Pug, Boxer), puppies under 12 months or days over 25 °C.
Yes, at 4 points: Entrago (start), Proaza (village centre), Buyera (finish, recreation area) and Tuñón (north access). All with wide spouts to fill bowls. Always carry a collapsible bowl so you don't depend only on public fountains.
No. It's a protected wildlife area run by the Fundación Oso de Asturias and pets are banned to avoid stressing the captive bears. If you're with someone, one stays outside for 15-20 min. If alone, better visit the enclosure on another day without the dog.
Don't approach the flock, go around it by at least 50 m, keep the dog on a short lead and walk calmly. Don't run: mastiffs read fleeing as a threat. Ignore the barking. If it comes to identify you, stop and sit your dog. Once it knows who you are, it walks away on its own.
€40 single deposit (same for standard and XXL) in cash or Bizum when you pick up the kit. Fully refunded if the trailer comes back clean and undamaged. Basic cleaning (sweeping fur) is on us — only specific damage like tears or bite marks is deducted.
Everything ready before you come
Choose the date, adult bike and the trailer you need based on your dog's weight. We don't ask for a card to book. The €40 deposit is paid at the shop (cash or Bizum) and returned when you hand the trailer back. Return transfer from Buyera included.
