Does anyone know if it's possible to take taxis along the way between Astorga and Ponferrada? I'm not even sure how close to a drivable road the camino is... And if I'm flaking out and the refugio is full and I need a nice bed and shower - how do I call a taxi to come and rescue me?? My mobile phone? Phone at the nearest refugio? Would just like the comfort of knowing that there is a safety net! Any advice appreciated.
