Without any doubt, the sanctuaries of the monarch butterfly are among the most popular attractions of Michoacán. And for a good reason. From late October / early November until March, millions of monarch butterflies stay in the forested highlands of Northwestern Michoacan (and near Valle de Bravo in Mexico State) for their winter hibernation.
These fantastic flying creatures travel thousands of kilometers to Michoacan, to escape the cold weather of Canada and the northern USA. After their long trip, they find in Michoacan a warm and relaxing place to rest. It is one of the most sophisticated animal migrations. Still, it is one of the most spectacular natural wonders on earth.
It is something that you must see, truly an experience of a lifetime. The most popular reserve areas are El Rosario and Sierra Chincua, near the town of Angangueo. You can either explore the forest walking or by horse. Day tours to the monarch butterflies are available both from Morelia and from Mexico City.
