The surroundings are at their best: everything green, mild climate, long days. One of the best options.
Summer
Jun · Jul · Aug · 20–28°C
The busiest time of year. Good weather almost guaranteed, but go early to avoid the heat.
Autumn

Senda del Oso in spring
Spring is one of the best times to do the route. The landscape is particularly green, the climate is mild and temperatures are pleasant — neither too cold nor too hot. Temperatures hover around 15–22°C.
The main drawback is that spring weekends can be quite busy, especially around bank holidays. If you can go on a weekday, all the better.
- Average temperature: 15–22°C
- Visitor numbers: moderate on weekdays, high at weekends
- Rain: possible, especially in March and April
Book in advance
Limited availability during peak season
Spring and summer are the busiest periods.
Senda del Oso in summer
Summer is the busiest time of year for visitors. Conditions are usually good, with long days and stable weather. Temperatures range between 20 and 28°C.
The main drawback is the crowds: July and August weekends are the busiest days on the route. If you have flexibility, weekdays are significantly quieter.
The most recommended approach in summer is to set off early — before 10:00 if possible — to ride in cooler temperatures and avoid the hottest part of the day.
- Average temperature: 20–28°C
- Visitor numbers: very high, especially at weekends
- Tip: go early in the morning, book well in advance
Senda del Oso in autumn
Autumn is another of the best times to do the route, especially September and October. The landscape changes completely: the ochre and reddish tones of the surroundings make the route particularly photogenic. And there are far fewer people than in summer.
Autumn temperatures are pleasant — between 12 and 20°C — and the atmosphere is peaceful. As November progresses, the chance of rain increases and the days shorten, but the route remains perfectly doable.
- Average temperature: 12–20°C
- Visitor numbers: low — very quiet on weekdays
- Rain: possible, more likely in November
Senda del Oso in winter
In winter the route is much quieter, but conditions can be more variable. Temperatures drop to between 8 and 15°C, and the chance of rain is higher. Daylight hours are also more limited.
That said, the route is perfectly doable in winter if the weather is good. The key is to check the forecast before you go and wear appropriate clothing: a waterproof, layers and comfortable footwear.
Important in winter
Always check the weather forecast before you go. If there is heavy rain or low temperatures, consider changing the day. If you book with us, you can change the date without any problem.
