We are doing Camino Le Puy and then walking to Pamplona where some of us will go back to US while others continue to Santiago de Compestela. I am realizing that the US government may still be requiring negative PCR tests for travelers to the US, even those that are fully vaccinated. I cannot find good information about how to get a PCR test in Spain (apart from info provided on this board about doing so in SdC). Does anyone have any insight? We have to get it within 3 days (not 72 hours but 3 calendar days according to CDC) of the flight so that means Roncevalles, Zuburi or Pamplona. A little worrying.
