The Pre-Inca Hydraulic Marvel Still Flowing in the Desert. While tourists crowd small airplanes to view the enigmatic Nazca Lines from above, an equally astounding engineering feat sits right on the desert floor: the Cantalloc Aqueducts (Puquios). Built over 1,500 years ago by the Nazca civilization, these subterranean stone water canals feature spiraling funnel-shaped access vents that still irrigate desert cotton and potato fields today.
Historical Significance & Archaeological Clues
In one of the driest deserts on earth, Nazca engineers tapped deep subterranean water tables originating in the Andes mountains miles away. The spiraling stone funnels (ojos) allowed air into the trenches to maintain water pressure and provided access for generational maintenance workers to clean the underground riverbeds.

Lesser-Known Secrets & What Most Travelers Miss
While standard travel guidebooks focus on superficial highlights, seasoned Andean trekkers and resident specialists know that the true magic lies in the details:
-
Water continues to flow crystal-clear through the channels today. -
The spiral shape prevents desert sand from caving into the underground canals. -
Allowed the Nazca culture to sustain thriving agricultural cities in hyper-arid desert. -
Ancient stone walls were assembled without mortar using river cobbles.
Practical Tips & Recommended Gear
Visit Cantalloc in the morning before the afternoon desert heat peaks. Bring a hat and plenty of drinking water. It provides an essential ground-level perspective on how the creators of the Nazca Lines actually lived and mastered their environment.
Essential Traveler Advice
Always carry small-denomination Peruvian Soles notes (10, 20 and 50 bills). Remote community checkpoints, pack-mule handlers, and artisanal weavers cannot make change for large 100 Soles bills or accept foreign credit cards.
Pricing, Permits & Availability (2026/2027)
Ticket entry is 10 PEN ($2.80 USD). A private taxi tour from Nazca hotel covering Cantalloc, Paredones ruins, and the ancient needle geoglyph costs roughly $20 to $30 USD.
