The Ministry of Foreign Affairs on Thursday relaxed travel advice for seven countries and the South Aegean Islands.

The Greek islands of Kos and Rhodes, among others, belong to this island group.

Holidays to Cyprus, Croatia (with the exception of the Sjeverna Hrvatska region), Liechtenstein, Switzerland and the aforementioned Greek islands are possible again immediately.

For those European destinations, code orange (travel only if necessary) will be weakened to code yellow (travel is possible, watch out for risks).

If the color code is yellow, travelers do not have to be quarantined upon return to the Netherlands and they do not have to submit a negative test result on arrival.

Travel advice for Iceland, Poland and Romania has also been relaxed.

Code green now applies to those countries.

That means there are no known security risks.

The countries have the outbreak of COVID-19 under control, according to RIVM.

Entry restrictions may still apply in the countries concerned.

The ministry also warns that the situation in a country can change quickly.

For example, the South Aegean Islands went from yellow to orange at the end of last month.

"The situation in the South Aegean Islands has now improved, making holiday travel possible again," the ministry said.
