On 4 July our travel advice changed, with exemptions for travelling to certain countries and territories that no longer pose a high risk for British travellers. View the list of exempted destinations. We continue to advise against non-essential international travel, except to countries and territories listed. We also currently advise against cruise ship travel
We are monitoring the international situation very closely and keeping this advice under constant review so that it reflects our latest assessment of risks to British people. We take a range of factors into account. For coronavirus, this includes the incidence rate and the resilience of healthcare provision in each country. Find out more about how our travel advice works
Developments in the coronavirus pandemic remain uncertain around the world. No travel is risk-free.
When you’re abroad
be prepared to comply with measures at your destination to manage a localised outbreak. If you test positive for coronavirus you are likely to need to get treatment locally and stay there until you have recovered. If you are required to quarantine or self-isolate by local authorities, you should expect to do so in the country. You may need to stay longer. Plan ahead for any delays to your return home and the financial implications or practical arrangements you may need to make

When you return

People were quick to criticise the government for acting slowly at the beginning, they have now acted quickly and people are still critical. Damned if you do, damned if you don't.
