Travel is possible from the UK to Sardinia. However, it is currently on the ‘Amber List’. If you choose to travel to Sardinia, you’ll need to take at least one pre-departure test, plus quarantine at home for 10 days upon return.
Before travelling, you’ll need to check that the travel insurance policy you have bought covers you for Sardinia’s entry requirements. For the most up-to-date travel advice – check the FCDO website.
