Rideshare pamplona

Uber isn't really a thing in Spain. Taxis are more commonly used, but you could look at BlaBlaCar which is a service where people can advertise for others to share their car. It's not on demand like Uber, you need to just look for someone travelling where you want to go.

We've used CaminoFacil twice now to get places that aren't convenient to get to by bus or train. They're also moving our gear between stops along Camino Santiago.

They drove us from Pamplona to St Jean Pied de Port to start our walk. And they drove us from Leon to Sarria.

thanks for the responses.
They seem to be pretty ubiquitous in Barcelona and Valencia (Cabify, FreeNow...) and a couple days ago saw Uber in Madrid as well, so the format if not a specific company is gaining some traction in the urban centers.
Keep on Traveling!
