Each winter, millions upon millions of monarch butterflies migrate to the fir forests of Mexico's Central Highlands. To walk among them and listen to the air hum with the vibration of their wings, is a truly magical experience. We'll make our first foray into the monarch kingdom at Piedra Herrada sanctuary before moving on to El Rosario, the largest monarch butterfly sanctuary in the country. The beauty of the butterflies is so ethereal that many Mexicans still hold the Aztec belief that the souls of the dead are reborn as monarchs. In addition, we'll explore Morelia, a UNESCO World Cultural Heritage site and one of Mexico's most beautiful cities. Come join WTT as we experience a side of Mexico that we'll be talking about for years to come.
