Ubiquitous day trip tours from Cuzco often include a stop in Q’enqo, a huaca (holy site) featuring dramatically large rocks. Though it’s technically part of the Sacsayhuamen Archeological Park, you also pass it on the road back to Cuzco after visiting Tambomachay.
It’s not so much the rocks that interest, but rather the tour of the ceremonial site in quasi-cave enclosure. Here you see a flat stone table that was once used for human sacrifices.
Open from dawn to dusk, we learned from our tour guide that if you go there earlier you might find people still making sacrifices here—not of humans, but of llama fetuses that you see for sale in Cuzco’s market.
If your Peru tour continues to Arequipa and a visit to Juanita’s mummy, making a stop in Q’enqo will help bring what you learn there into better focus.
