Mae Cymru'n dilyn yr un dull goleuadau traffig â gweddill y DU ar gyfer teithio rhyngwladol. Dosberthir gwledydd fel rhai gwyrdd, ambr a coch yn dibynnu ar eu statws iechyd cyhoeddus a chyfraddau brechu. Dim ond llond llaw o gyrchfannau sydd â statws gwyrdd.
Wales is following the same traffic-light approach as the rest of the UK for international travel. Countries are classified as green, amber and red depending on their public health status and vaccine rates. Only a handful of destinations have green status.
