Located 300 km (around 190 miles) northwest of Hanoi, Mu Cang Chai district in northern Yen Bai province had become a hit with foreign and local tourists alike before the coronavirus pandemic.
The terraces mostly belong to the Hmong, a minority group who make up most of the area's population
The spectacular terraces -- which lie up to 1,000 metres above sea level -- mostly belong to the Hmong, a minority group who make up most of the area's population.
The Hmong women once rented their colourful traditional costumes to visitors, while men earned up to $30 a day driving them up tiny muddy paths through the hills.
The paddy fields are particularly beautiful in September and October, when the crops turn a shiny yellow.
"We used to get huge numbers of tourists," farmer Lo Thi Loan told AFP.
"But this year all the rice fields are empty... due to virus movement restrictions."
Vietnam has recently started to open its doors to the outside world, and some international visitors arrived earlier this month on the island resort of Phu Quoc and in other tourist areas further south.
But it is not clear when the country will fully open, as it continues to battle a serious outbreak of Covid-19.
