"Kuélap At 9800 feet (3000 meters) above sea level, this is one of the Chachapoya culture’s most important archaeological sites, a military fortification protected by stone walls as high as 65 feet (20 meters). The compound includes traces of over 450 circular residences, all but identical, a main temple, a cemetery, and sundry other structures and enclosed spaces. Take the cable car—Peru’s first—to get there, at 20 soles or $6 round-trip."
