5Monarch Butterfly Migration, Mexico

Millions of monarch butterflies make the annual migration south from Canada to Mexico for the winter, where they turn the fir trees of Michoacán into a living, breathing natural art installation.

However, the true burst of colour comes when they rise from their pine tree slumber, fluttering through the air, transforming their richly pigmented orange and black wings into a tangerine blur. When to See the Butterflies: Best visited between January and March, on calm, warm days.
