From Pari-Aike to Perito Moreno: A Town of Many Names

The town now known as Perito Moreno was originally a rest stop for travelers near the springs that feed the Río Deseado. The indigenous Tehuelche people called this place "Pari-Aike," meaning "place of reeds" or "birth," due to its proximity to the river's source. European settlement began around 1890, with Spanish, English, Arab, and Italian families establishing farms and ranches in the area.

In 1927, the town was officially named Nacimiento by national decree. This name was changed again in 1944 to Lago Buenos Aires, reflecting its proximity to the large lake of the same name. Finally, in 1952, the town received its current name, Perito Moreno, in honor of the Argentine naturalist and explorer Francisco Pascasio Moreno. Moreno played a role in defining the border between Argentina and Chile in the late 19th and early 20th centuries and was instrumental in establishing Argentina's national park system. The town was declared the Archaeological Capital of Santa Cruz in 1981, recognizing its significance as a gateway to ancient rock art sites.

The Legacy of Francisco Pascasio Moreno

Francisco Pascasio Moreno, born in Buenos Aires in 1852, dedicated his life to exploring and documenting Patagonia. He undertook expeditions in the 1870s, mapping rivers, plateaus, and lakes that were largely unknown to the Argentine state, though familiar to the indigenous Tehuelche and Mapuche peoples. In 1877, he named Lago Argentino and Mount Fitz Roy. His surveying work was vital in the 1902 Arbitral award of the Andes, which helped designate much of Patagonia as Argentine territory. In recognition of his contributions, the Argentine government granted him the honorific title 'Perito' (expert) in 1897. In 1903, Moreno donated a portion of land around Lago Nahuel Huapi, which became the nucleus of Nahuel Huapi National Park, South America's first national park. While he never saw the Perito Moreno Glacier in person, it was named in his honor in 1899.

Perito Moreno serves as a hub for exploring the natural and archaeological heritage of Santa Cruz Province.

• —Cueva de las Manos — This UNESCO World Heritage site, located about 170 km south of town, features cave art created between 9,300 and 1,300 years ago. The site is known for its stenciled outlines of human hands, as well as depictions of animals like guanacos. The paintings were made with natural mineral pigments such as iron oxides (red and purple), kaolin (white), natrojarosite (yellow), and manganese oxide (black).
• —Río Pinturas Canyon — The Cueva de las Manos is within this canyon, which offers landscapes and archaeological sites on both sides of the river. The canyon is a geological formation, shaped by millions of years of processes.
• —Parque Laguna — This park provides an opportunity to observe Patagonian fauna and offers views of Laguna de los Cisnes (Swans Lagoon) and the valleys of the Fénix and Chico Rivers, as well as the source of the Río Deseado.
• —Lago Buenos Aires — Located 25 km east of Perito Moreno, this lake is shared with Chile (where it is known as General Carrera Lake). The area around the lake offers scenery and is a gateway to further exploration of the region's natural features.
• —Carlos J. Gradin Museum of Archaeology — Named after the Argentine surveyor and archaeologist who conducted research at Cueva de las Manos starting in 1964, this museum in Perito Moreno is dedicated to the region's archaeological findings.

The best time to visit Perito Moreno and the surrounding region is during the shoulder seasons of spring (November–early December) and autumn (March–April). During these months, the weather is stable, and tourist crowds are smaller compared to the peak summer season (December–February). Temperatures are milder, ranging from 10°C to 15°C (50°F to 59°F) in spring and autumn, making it comfortable for outdoor activities. Summer offers the warmest weather, with average daily highs around 22°C (72°F) in January, but also the highest prices and busiest attractions. Winter (June–August) is cold, with average lows around -2°C (28°F) in July, and strong winds are common year-round. Avoid winter if you prefer milder temperatures and longer daylight hours for exploration.

Perito Moreno is in the northwest of Santa Cruz Province, at the crossroads of Ruta 40 and RN 43. RN 43 connects the town to Caleta Olivia on the Atlantic coast and Los Antiguos near the Chilean border. The Perito Moreno Airport (PMQ) serves the town, located about 7 kilometers northwest. The town itself is small and walkable. Exploring the wider region, especially sites like Cueva de las Manos, requires transportation. Renting a car offers flexibility. Public buses are also an option for reaching nearby attractions. Parking within the town is generally straightforward. Food options inside national parks can be limited, so bringing snacks and a refillable water bottle is advisable for day trips.
