Every winter, millions of monarch butterflies transform the montane cloud forests of central Mexico into a breathtaking spectacle. The Monarch Butterfly Biosphere Reserve is one of nature’s greatest shows—a once-in-a-lifetime experience for any wildlife enthusiast. But the magic doesn’t stop there.

Central Mexico also boasts world-class birding, from the urban oases of Mexico City to the pristine forests of Valle de Bravo. This 8-day adventure with Reefs to Rockies and Denver Audubon blends the thrill of birdwatching with the awe of the monarch migration, all while immersing you in the rich culture and history of Mexico.

Join Reefs to Rockies and Denver Audubon next January for an unforgettable journey through Mexico's natural and historical wonders.
