Visiting the Monarch Butterfly Biosphere Reserve
Set within the mountains of Michoacán and the State of Mexico, the Monarch Butterfly Biosphere Reserve is a protected natural site where millions of butterflies migrate each year from Canada. This massive phenomenon takes place between November and March, turning the forest into a living sanctuary.
A Fascinating Migratory Journey
Every autumn, monarch butterflies travel more than 4,000 kilometres to reach the oyamel fir forests of central Mexico. Their arrival marks the start of a unique spectacle: tree branches heavy with orange wings and a constant rustling sound as the butterflies take flight at the slightest ray of sunlight.
Trails for Observing the Colonies
Several sanctuaries provide access to the colonies. Among the most visited, El Rosario and Sierra Chincua feature trails leading to the viewing areas. Visitors can choose between hiking or taking horseback excursions to reach the high-altitude spots where the butterflies cluster. The elevation and cool climate call for good physical fitness and warm clothing.
A Fragile Ecosystem to Protect
Designated as a UNESCO World Heritage site, the reserve is a fragile ecosystem governed by strict regulations. To limit human impact, access to the colonies is regulated and visitors must stay on marked paths. Local guides share insights on conservation efforts and the threats facing the butterflies, notably deforestation and climate change.
Opening hours
Scheduled excursions daily, 9:00 AM to 5:00 PM
Access is limited during poor weather conditions
If you are into nature's treasures, this reserve will fascinate you. If you go in the winter (plan on 2.5 to 3 hours by bus each way from Mexico City), you will see patches of forest filled with beautiful butterflies. I do not think you can see anything like this anywhere else in the world.
