The US National Park Service announced a series of measures meant to control the outbreak of COVID-19 through its official website on March 17.
The administration also presented a special online tour, encouraging people to pay virtual visits to the places they like.
Due to the impact of the epidemic, many famous tourist attractions in the US have to close.
The list included many national parks, such as Yellowstone, Rocky Mountain and Yosemite, and there is no access to the Statue of Liberty or the Washington Monument.
About 419 national parks and historical sites are under the operation of the US National Park Service. As an institution of the federal government, the service was established in 1916 to enhance protection of the country’s natural and cultural heritage.
