The number of foreign holidaymakers staying in Spanish hotels fell almost 66% in March to 1.19 million.
The deep drop came as the coronavirus pandemic forced the tourism-dependent country to impose one of the strictest lockdowns in Europe.
Hotels were ordered to gradually shut down form March 19 until complete closure on March 26 as a state of emergency was declared.
The occupancy rate nearly halved last month to 29% from 53% in March last year, according to data released by the tourism-dependent country’s national statistics institute.
The overall number staying in hotels fell 65% to 2.63 million people, leading to a cumulative drop of 22% since the start of the year, the Majorca Daily Bulletin reported.
Spain is among the world’s worst-hit countries by Covid-19, with a death toll of nearly 22,000 and more than 204,000 infections.
Tourism accounts for 12% of the nation’s gross domestic product.
