"Come with me to visit the largest monarch sanctuary in the world, El Rosario. The monarch season is at its peak and a trip to see the butterflies is a special treat."

Meet the Sanctuary Guides
Estela interviewed two guides about their work at the monarch sanctuary:

"What I love about being a guide is the fact that the whole community has a chance to make a living," said Eduardo.

"Our parents tell us that we are the monarch generation. Since we were born, monarchs have been part of our lives," said Lorena.
