One of the most amazing phenomena in nature is the annual migration of Monarch butterflies (Danaus plexippus) southward from their breeding grounds in the United States and Canada to overwintering sites high in the mountains of southern Mexico. Hundreds of millions of Monarchs fly along the Gulf Coast, or across the Gulf of Mexico, to eventually reach the belt of high volcanic mountains which stretches across the southern end of the central Mexican plateau. At about a dozen isolated places within the high altitude forests of this zone, Monarchs pass the winter in aggregations that can exceed 2 billion individual butterflies. Stand amid the fir-covered mountains and witness this awe-inspiring spectacle firsthand as the monarchs flutter, dip, and swoop overhead.

Lewis & Clark professor Paulette Bierzychudek’s expertise regarding ecology, biology, and environmental studies will be a resource along the journey.

Trip Highlights

  • Hike or ride horseback to three different monarch reserves in Michoacán, where millions of individual monarch butterflies gather.
  • Photograph the dramatic colors of the butterflies as they hang in clusters from the trees, drink from streams, feed on wildflowers, and soar in the air above.
  • Visit the pyramids at Teotihuacán, one of the most architecturally significant Mesoamerican sites of pre-Columbian times.
  • Spend time exploring colonial Angangueo, which was once a mining town but now derives most of its livelihood from butterfly ecotourism and agriculture.
