Complete seasonal guide
It can be ridden all year, but not every season is the same. Spring and autumn are the best for climate, colours and quiet. Here's what to expect month by month.
Start with the quick answerQuick answer
If you just want to know when to come without overthinking: the best windows are May-June (late spring) and September-October (early autumn).
For three reasons
Mild temperatures
15-22 °C, comfortable for pedalling or walking without being too hot or cold.
Few people
Nowhere near the July-August crush, and not the November-March tourist lull either.
Forest at its best
Spring growth or autumn ochres, a lush landscape either way.
If you come in July-August, set off early. If you come in winter, check the weather forecast.
The 4 seasons
Weather, crowds, what you will see, pros and cons of each period. Spring and autumn are the recommended ones.
March–May
The season that wakes the forest
What you will see
Few people in March-April. Vivid colours and clean air after the rains.
Rain likely — a light shell is a must. Muddy surface after showers.
Tip Easter week can be busy. Book ahead if it falls in March-April.
June–August
High season. Beautiful but crowded.
What you will see
Plenty of daylight. Pleasant temperatures thanks to the forest shade.
Car parks full before 10:00. Bike booking essential.
Tip Come midweek if you can. August weekends = everything full.
Sept–November
The other great season, with the most spectacular colours.
What you will see
October: peak colours + mild temperatures + few people.
More frequent rain from late October. Fewer daylight hours in November.
Tip Late September or the first two weeks of October — the best window of the year.
Dec–February
The quiet season. Beautiful but with harsher conditions.
What you will see
Trail practically empty. Long views through the leafless forest.
Slippery surface. Few daylight hours. Many cafes closed midweek.
Tip Doable for locals and anyone who knows the terrain. If it is your first visit, pick another season.

What to bring by season
Minimum kit we recommend depending on when you come. Everything fits in a small backpack — no technical gear needed.
Variable weather. A rain shell is essential. Wrap up in the morning, lighter layers at midday.
Heat and heavy crowds. Protect yourself from the sun, stay hydrated and set off early to avoid the crush.
Cold and few daylight hours. Thermal kit and head torch are essential. The surface can be slippery.
Whatever the season, these 4 items should never be missing from your bag.
Events and moments
Events, fiestas and special moments that may shape (or improve) your visit to the trail.
In the wild zone — does not affect Molina but it is the period when FOA (Fundación Oso de Asturias) activates more monitoring work.
Booking a bike in advance is essential. It is the first tourism wave of the year.
Cultural programming in Teverga, Proaza, Quirós and Santo Adriano. A good chance to discover the villages.
Festivals in nearby concejos. Seasonal cuisine in the local restaurants.
Partial hibernation. She may not be visible for weeks. If you are coming to see her, pick another season.

+34 644 199 430Late spring (May-June) and early autumn (September-October) are the best. Mild weather, few people, landscape at its finest. If you have to pick a single month, October ties everything together: autumn colours, pleasant temperatures and little crowd.
Yes, no problem. A large part of the route runs under the shade of the riverside forest and passes through cool tunnels. Temperatures rarely exceed 28 °C in Asturias. Set off early (before 10:00) to avoid crowds and the midday heat.
Yes. The trail is open all year, it never closes. In winter the surface can be slippery from damp or ice, and there are few daylight hours — but it is rideable. The tunnels keep photovoltaic lighting even with little sun.
It can be difficult. Brown bears enter torpor (partial hibernation) between December and February. Molina spends weeks sleeping in sheltered areas of the enclosure, sometimes without coming out. If you are coming specifically to see her, better spring, summer or autumn.
January and February, by far. The trail is practically left to the locals. If you are after total silence and have the kit for cold weather, those are the quietest options. Runners-up: March and November.
In August, patron-saint fiestas in the concejos of Teverga, Proaza, Quirós and Santo Adriano — with cultural programming. In October, chestnut festivals and seasonal cooking at the local restaurants. In spring, pilgrimages in several villages.
For any season
We operate year-round with wide opening dates. In high season (July-August, long weekends, Easter), book at least a week ahead. In winter or midweek, letting us know the day before is enough.
