Layers of ash settled on houses and fields on the Indonesian island after an eruption of Mount Agung.
Up to 100,000 people were ordered to evacuate the vicinity and thousands of tourists have been stranded.
The airport might have to close again if the wind changed direction, officials said.
Not all local people have left - some have insisted on waiting until lava from the crater heads their way.
The massive plumes of dark ash from Mount Agung were seen reaching as high as 3km (2 miles) above its rumbling summit. It began erupting last week.
