It depends on the type of rain. With drizzle or short showers, the Bear Trail is perfectly doable: much of it runs through woodland and the old railway’s 30-plus tunnels shelter you every few hundred metres. With heavy, steady rain or a storm, better to leave it for another day: since you book without paying in advance, rescheduling costs you nothing. This is the advice we give every day over WhatsApp to anyone hesitating over the forecast.

This guide tells you when to go and when not to, what to bring if it catches you on the route and what plan B you have in Teverga.

Three types of rain, three answers

Drizzle or “orbayu” (fine, intermittent rain). Totally doable. Much of the trail runs under dense woodland and the 30-plus tunnels give shelter every 300-500 metres. With a light layer and no rush it can be the most beautiful version: low mist, damp forest and silence. Postcard Asturias.

Short showers (intervals). Doable with a strategy: set off when it clears and take shelter in a tunnel or a bar if it picks up. The downhill Entrago → Buyera route is 2-3 hours with stops, perfect for making the most of the bright spells. The child and dog trailers come with a cover, so the little ones and the dog stay dry.

Heavy, steady rain or a storm. Better to cancel and reschedule. You don’t pay in advance, so reorganising the day costs nothing. And if there’s an active electrical storm, don’t go onto the trail: there are stretches in the gorges with exposed rock.

What to bring if it rains (or might rain)

Always, even if the sun is out (Asturias changes in ten minutes):

  • A light rain layer, poncho or waterproof.
  • Shoes with good grip: the gravel surface doesn’t turn to mud, but it can be a bit slippery.
  • A charged phone.
  • Dry spare clothes in the car or the accommodation for afterwards.

If rain is certain:

  • A waterproof jacket, better than a poncho if it’s going to be all day.
  • Light waterproof trousers, optional.
  • Thin gloves in winter.
  • Spare merino wool socks: dry feet, day saved.

The full list, summer and winter, is in what to bring to the Bear Trail.

What the surface does in the rain

The trail has a compacted gravel (zahorra) surface, ideal for this climate:

  • It doesn’t turn to mud like dirt tracks do.
  • It drains water well; the main stretches don’t flood.
  • It can be a little slippery on the gradients (minimal, 1.5%): take it easy.
  • Inside the tunnels the surface is drier, a comfortable refuge.

If it catches you on the route and gets worse

  1. Take shelter in the nearest tunnel or in the bar in Proaza.
  2. Shorten the route: the return transfer leaves from Buyera, the end of the short route, so you can finish earlier there and head back without pedalling uphill. If you rented the bike with us and have any doubts, call us on +34 644 199 430.
  3. Don’t force the route: there are no medals.

Plan B in Teverga in bad weather

If you decide not to ride, the area has plenty of indoor options:

  • Prehistory Park of Teverga: a museum with a replica cave, an hour-and-a-half visit.
  • Bear House in Proaza: interpretation centre, one hour.
  • Eat at a sidrería (cider house): fabada, roxa beef and cider. Museum in the morning, a table at midday.
  • The Cueva Huerta cave in Teverga, with a guided tour (book ahead, confirm before you go).

If you’re staying in the area, a museum day and a trail day when it clears fit together perfectly. To pick dates with less rain risk, check the best time of year for the Bear Trail.

When it rains most on the Bear Trail

Approximate figures:

  • Wettest months: November, January, February and April.
  • Driest months: July and August.
  • Most unpredictable months: March, May and October, with the odd heavy downpour.

It rains all year round in Asturias, but rarely for several days in a row: the 24-48 hour window of clear skies is common even in the wet months. If you want the full context of the route, you’ll find it in the Bear Trail guide.

Our tips

“A day of fine rain is the best day to photograph the trail.” Low mist between the gorges, soaked woodland and a swollen river. The photo takes itself.

“Check the local forecast the night before and again when you get up.” AEMET gives the hour-by-hour forecast for Entrago. Don’t trust the general “Asturias” forecast: the south-west has its own microclimate.

Book without weather worries

With a good forecast, any time of year is good for riding the Bear Trail; and if the day turns bad, we reschedule it. Book your bike with no advance payment and, if it’s bucketing down at dawn, we’ll talk and change it. If you’d rather have warmth and long days, see how to ride the Bear Trail in summer.
