Visitors who have been fully vaccinated can enjoy tours in the central province, while those who have received one COVID vaccine dose will need to furnish a negative COVID-19 certificate obtained via RT-PCR or rapid testing.

Vaccinated visitors would be allowed to join package tours with pandemic prevention measures in place and certain limitations to avoid the risk of infection.

Quang Binh, home to UNESCO heritage site Phong Nha-Ke Bang National Park, boasts many limestone caves including Son Doong, the world’s largest. Quang Binh welcomed half a million visitors in the past nine months, down 66% year-on-year.
