Why camp on Copacabana?
Organisers say about two million people have packed Copacabana Beach in Rio de Janeiro for the last evening of World Youth Day with Pope Francis.
The night-long vigil service marks the climax of the five-day festival and culminates in a huge Mass on Sunday.
The BBC's Julia Carneiro spoke to two young women camping out on the beach to find out about their plans for the evening.
