Millie Bobby Brown was one of the thousands of people stranded on the Indonesian island of Bali after volcano Mount Agung erupted.

What was originally meant to be a four-day break turned into a 10-day mini vacation as a result of the airport being shut down for a couple of days due to the volcano’s ash that filled the air. The “Stranger Things” actress, 13, shared photos from her extended stay and thanked everyone she met and said a prayer for the Balinese people who have been affected by the eruption.

“I would really love to thank all of the staff at the @themuliabali for taking such good care of us while having to extend our stay here; I cannot thank you enough! Also, to the Balinese people who are the sweetest, kindest and most humble people I’ve ever met,” she wrote. “But most of all, my thoughts and prayers are with the people whose lives have been affected by this. I truly hope everyone there stays safe. Sending all my love to Bali.”

Agung’s last major eruption in 1963 killed about 1,100 people.

The closure of the airport stranded tens of thousands of travelers. More than 400 flights were canceled on Monday and nearly 60,000 travelers affected, an airport spokesman said.
