If you are so lucky to be visiting Iceland soon see here what the rules regarding entry are. We are aware that there has been a rumor going around that travellers need to take a test BEFORE arriving. That is not true, you can choose between taking a test at Keflavík Airport or self-isolate for 14 days.
Happy travels!
