Journey into the highlands of Central Mexico on our Kingdom of the Monarchs adventure with women Expedition Leaders eager to share their passion for this region’s natural and cultural heritage.

Discover the resilience of female monarchs, each of which lays between 300-500 eggs and migrates 3,000 miles each year from the northern U.S. and Canada to Mexico.

Walk the trail blazed by Cathy Aguado—discoverer of the monarch butterflies’ overwintering site in 1975—and experience the sight and sound of millions of fluttering wings. Ride horseback through the oyamel fir forest, learn about monarch conservation efforts and witness how ecotourism supports the rural mountain town of Angangueo.

You’ll return home not just awed by the monarch migration but also inspired by the many women whose heroic efforts have preserved Mexico’s butterfly sanctuaries and protected North America’s monarch populations.
