About 4km southeast of town are the 30-plus underground Cantallo Aqueducts, which are still in working order and essential in irrigating the surrounding fields. Though once possible to enter the aqueducts through the spiraling ventanas (windows), which local people use to clean the aqueducts each year, entry is now prohibited; instead, you can take note of the Nazca’s exceptional stonework from outside.
It’s possible, but not necessarily safe, to walk to the aqueducts; at least, don’t carry any valuables. Alternatively you can hire a taxi to take you there. This should cost around S40 to S50 round-trip. Tours from Nazca that take 2½ hours, cost from S15 per person and may be combined with a visit to see El Telar, a geoglyph found in the town of Buena Fe, and visits to touristy gold and ceramics workshops.
Admission also covers entry to the nearby Pardeones Ruins.
