Where international travel is essential, Welsh residents must consult the requirements for visitors for any country they plan to travel to. Tests may be required for entry. For anyone planning on travelling to Wales, we continue to require people to take tests before travel and following arrival in Wales. All travellers must take a pre-departure test up to 72 hours before travel and present proof of a negative test to carriers. In addition, travellers must book and pay for mandatory PCR tests to be taken following their arrival to Wales. Following the changes announced this week relating to amber list countries, fully vaccinated adults and under-18s will need to take a PCR test on or before day two following their arrival in the UK and will no longer be required to self-isolate.  In the absence of self-isolation it will be very important to take care about physical contact with others. Visiting people in a hospital or care home during the first 10 days back should be avoided. Those who are not fully vaccinated will need to continue to take PCR tests on day 2 and on day 8 and to self-isolate for 10 days. Travellers arriving from green countries must take a PCR test on or before day 2.
