Quarantine requirement at government designated site and self-isolation at home. Once you arrive in Sri Lanka you need to follow the guidance for not-vaccinated and not-fully-vaccinated travellers. You will need to stay in a Tourism Bio Bubble until either you reach 14 days post vaccination or 7 days after arrival (whichever comes first will apply for not-fully vaccinated travellers). You will be allowed to visit approved tourist sites and use all facilities of the hotel upon negative results of the on-arrival PCR test. Further details can be found on the Sri Lanka Tourism Development Authority website. Find out if you qualify as fully vaccinated in Sri Lanka on the Sri Lankan Tourism Development Authority website.

Children between the age of 12-18 who have obtained at least a single dose of a recognised vaccine (at least 2 weeks before travel) will be considered ‘fully vaccinated’.
