I’ve cycled in the Pyrenees twice and this region has plenty to offer in terms of challenging rides, great scenery, wonderful culture and lots interesting little roads to explore. I’ve never cycled the Picos de Europa, but I did cycle past them and they do look magnificent. A friend of mine hiked the Picos and she said the weather can be unpredictable and that she was stranded in fog for 1 week! Spain and southern France have a lot of wonderful places to cycle so wherever you choose to go it will be great.
Where will you be located?
