Sierra De Los Piojos

Rising abruptly from the plains of northern Uruguay, Sierra de los Piojos is a rugged, little-visited range of granite hills that rewards hikers with sweeping panoramas, hidden waterfalls, and a genuine sense of discovery. This is a place for those who want to trade crowds for solitude and connect with the raw landscapes that define the region's interior.

Highlights & What to See

• Cerro de los Piojos – The highest summit in the range, offering a challenging but rewarding climb with 360° views across the rolling countryside and, on clear days, all the way to the Atlantic.
• Saltos del Penitente – A series of crystalline waterfalls plunging into deep, emerald pools perfect for a refreshing dip after a hike.
• Valle del Lunarejo – A protected valley within the range, known for its rich birdlife and unique flora, including ancient ferns and orchids.
• Piedra del Águila – A massive granite outcrop resembling an eagle, a popular spot for rock climbing and photography.
• Estancia tourism – Several working ranches offer horseback rides, traditional asado barbecues, and a glimpse into gaucho culture.

Suggested Time to Spend

Two to three days is ideal for experiencing the Sierra's highlights without rushing. Dedicate one full day to summiting Cerro de los Piojos and exploring the Saltos del Penitente, and a second day to Valle del Lunarejo and a visit to an estancia. If you have a third day, consider a longer hike along the ridge or a rock-climbing session at Piedra del Águila. The area is best visited from late spring to early autumn (October to April) when temperatures are pleasant.
