The Spanish Government declared a ‘State of Alarm’ on Sunday October 26th, which remained in place until May 9th, 2021. During this period, the Camino was, to all effects, closed, as movement between regions in Spain was severely restricted or not allowed.
As of May 9th, there are NO mobility restrictions in Spain between Autonomous Regions and Provinces. Furthermore, regional governments can ONLY enforce municipal lockdowns, but NEVER Provincial or Autonomous Regional ones. Applied to the Caminos de Santiago in Spain, this means that nothing can stop you from crossing Spain, but that you may encounter a town that is confined.
However, there continue to be other pandemic-related restrictions in Spain, and these may vary significantly depending on the Autonomous Community.
Unless another State of Alarm is declared, this is the general situation in Spain.
