Os de Civís is a village in the central Pyrenees mountains, in the municipality of Les Valls de Valira in Catalonia, Spain, and is located to the west of Andorra, near the villages of Aixàs and Bixessarri. Os de Civís is very close to the Spain–Andorra border, and is unique in being the only Spanish village that can be reached by vehicle only by going through Andorra. The border crossing is unique in Andorra in that there is no border control: Andorra is in neither the Schengen Area nor the European Union, and thus operates full border and customs checks at all other border crossings with Spain and France, but the crossing to Os de Civís is unpoliced as the road leads solely to the village, with no access to anywhere else in Spain. Os de Civís is therefore a pene -enclave – a place connected by land with the rest of the country or province, but to that in practice it can only be accessed through another country.

The Village
The village is picturesque with narrow streets and stone built buildings. Many of the cars have Andorran number plates.

Are you familiar with the road or trail from Farrera, Spain to Os de Civis? We are bikepacking (bicycles) through the area and looking for the best route to Os de Civis.
We read that there is limited access to Os de Civis.
Thanks!

I’m not I am afraid, there are woodland trails, but some areas are restricted and people are not allowed access. I would think a detailed map might give you the information you need.
