Today is November 2nd, All Souls Day. It’s a little-known or observed holiday in most of the U.S. outside Catholic circles, but in Mexico, the date is heralded by a remarkable natural phenomenon that happens each year in the fir-clad mountains of central Mexico.
Like clockwork, millions of monarch butterflies return to these remote forest sanctuaries during “El Dio de los Muertos,” the 3-day span from October 31 to November 2 when the Christian holy days of All Hallow’s Eve, All Saints Day and All Souls Day are celebrated collectively as “The Day of the Dead.”
Since pre-Hispanic times, Purépecha Indians have recorded the arrival of the long, flowing cloud of orange-winged butterflies that pours into the Sierra Madre hills above the village of Angangueo at precisely the same time each year.
They believed that souls did not die but continued living in Mictlan, a place for spirits to rest until the day they could return to their homes to visit their relatives. Later, as Catholic traditions intermingled with indigenous cultures, the monarchs came to be regarded as the souls of departed ancestors returning to earth for their annual visit.
Each year during the Days of the Dead, local people honor the spirits through festive events focused on the butterfly migration. Historically, this holiday time is one of remembering and rejoicing for the deceased, whose earthly bodies are exchanged for spirits ready to move to the next realm, unencumbered by worldly woes as they transition ultimately to heaven. The gossamer-winged butterflies are thus the perfect manifestation of such liberated souls.
Visitors to Angangueo—or most anywhere in Mexico—will find townspeople dressed up as ghosts, ghouls, skeletons and mummies, parading through the streets with an open coffin containing a smiling “corpse.” Bystanders toss oranges, fruits and candies into the coffin as the mock funeral procession makes its way through the village streets. Inside homes, families erect ofrendas, or altars, on which they place photographs of deceased family members and offer flowers, bread and treats, which are partaken of “spiritually” as the spirits return. Later, the living enjoy the offerings in material form. In the evening, the altars are lit by candles that are kept burning all night long.
The festivities commemorate two celebrations that honor the memory of loved ones who have died : On November 1st, All Saints Day, the souls of children are honored at the altars, which feature white flowers and candles. On November 2nd, All Souls Day, departed adults are remembered with a variety of rituals that differ between the various states of the Mexican republic.
The state of Michoacán in west-central Mexico is where the butterflies add a vibrant touch to Day of the Dead celebrations. Some 300 million “mariposas” are currently arriving there, having traveled over 2,000 miles from the northeast U.S. and southeastern Canada. Their migration remains a mystery to scientists, who aren’t yet certain how the butterflies manage to find this small, isolated sector of oyamel trees that they have never been to before. The unique microclimate is perfectly suited for overwintering and breeding, however, and the monarchs will spend 4-5 months here before making their way northward again for the summer.

And if you’d like to experience for yourself what it’s like to stand among millions of gentle butterflies, join one of our small-group trips to the Mexican sanctuaries this winter. This rare habitat is set aside as the Monarch Butterfly Biosphere Reserve, a UNESCO World Heritage Site, to protect and conserve this extraordinary migration phenomenon, which you’ll get to witness up close on our intimate adventures.
Yours in the Spirit!
