Stubbornly unfazed by warnings of “soroche,” or altitude sickness, I swung my legs up onto a donkey and began to ascend the steep trails. After trekking for a few dizzying hours alongside hundreds of others, I approached a glacial basin. The scene began to unfold before us: an immense valley flooded with so many pilgrims that it seemed to be covered in confetti, each tiny speck representing a huddled collection of tents and people.

The altitude sickness began to overtake every inch of my body. Even my eyeballs ached. But, undeterred, I slowly navigated through the throngs of people trying to take in every sight and sound.


Each year in late May or early June, thousands of pilgrims trek for hours on foot and horseback through Peru’s Andean highlands — slowly snaking their way up the mountainous terrain — for the religious celebrations of Qoyllur Rit’i, held some 50 miles east of Cusco, once the capital of the Incan empire.

Practiced annually for hundreds of years, the celebrations mark the start of the harvest season, when the Pleiades, a prominent cluster of stars, return to the night sky in the Southern Hemisphere. The syncretic festival, which is on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity, interweaves Indigenous and Incan customs with Catholic traditions introduced by Spanish colonizers, who sought to undermine Andean cosmology.
Celebrations were suspended this year because of the coronavirus pandemic, with the route to the valley completely blocked off. But when I attended in 2013, the crowds were remarkably dense.


The festival takes place in the Sinakara Valley, a glacial basin that sits around 16,000 feet above sea level. Celebrants swarm in colorful droves with costumes, enormous flags, instruments and provisions in tow.
