Tours of Peru's Ancient Enigmas
Walk among the mysteries of the ancient Andes
From the Nazca Lines to the megaliths of Cusco — expedition tours into the questions archaeology still can't answer.
Welcome
Peru's enigmas, explored first-hand
Andean Mysteries runs small-group expeditions to the most extraordinary and least-explained places in Peru. We fly you over the Nazca Lines, stand you before 120-tonne stones fitted without mortar, and put the elongated skulls of Paracas within arm's reach — pairing the archaeological record with the theories that refuse to go away.

Departures from Lima
Coastal Enigmas
The Nazca desert, the elongated skulls of Paracas, and the UFO hotspot of Chilca — Peru's densest concentration of mysteries, all reached from the capital.

Impossible Stonework
Polygonal megaliths locked together without mortar, and the carved trapezoidal ‘portal’ of Naupa — on foundations that may be far older than the Inca who inherited them.
Three Thousand Years
A timeline of the impossible
The cultures behind the mysteries — and the questions each one left carved into stone.
1200 BCE
Chavín de Huántar
A labyrinthine temple complex with engineered acoustics and hidden water channels rises in the Áncash highlands — the wellspring of Andean religion.
800 BCE – 100 CE
The Paracas Culture
Master weavers of the southern coast leave behind extraordinary textiles — and hundreds of elongated skulls that still divide scholars.
500 BCE – 500 CE
The Nazca Lines
Across 450 km² of desert, the Nazca inscribe vast animals and kilometres-long straight lines visible only from the air. Nobody fully agrees why.
300 – 1000 CE
Tiwanaku & Puma Punku
On the Bolivian altiplano, andesite is worked into H-blocks so precise they look machined. The dating and the method remain fiercely debated.
1200 – 1533 CE
The Inca (and what came before)
The Inca raise Sacsayhuamán and Ollantaytambo on foundations whose polygonal megaliths may predate them — the great open question of Andean archaeology.
At Sacsayhuamán
“Try to fit a knife-blade between the stones and it will not pass.”
