According to this document from Citizens Advice Bureau Spain, Spain will open its borders at the end of the 6th extension to the State Of Alarm. The 6th extension officially ends at 24:00h on the 21st June 2020, which means the borders and movement restrictions will return to normal at 00:00 on the 22nd June 2020.
