Borders with Austria and Germany reopened on June 5, 10 days earlier than expected. The country opened its frontier with Slovakia and Hungary on May 27, but with restrictions.
The other EU countries have been divided into coloured groups dependent on risk: green, orange, and red.
From June 15, Czech residents and EU citizens from green countries — eastern and Baltic member states, Finland and Norway — were able to travel to and from the country without any requirements.
Those from the yellow group, which includes France, Italy, and Spain, must have a valid health certificate to enter.
Test and quarantine conditions will apply for people entering from the UK and Sweden — the two red nations in Europe.
