Road to Perito Moreno Glacier: Driving the Wild Heart of Argentine Patagonia
The road to Perito Moreno Glacier is one of the most spectacular drives in South America. Starting from El Calafate in the Santa Cruz Province of Argentine Patagonia, the route covers approximately 80 km (50 miles) of pure Patagonian landscape before arriving at the glacier's viewing platforms inside Los Glaciares National Park — a UNESCO World Heritage Site.
The drive follows Ruta Provincial 11 (RP11), a paved two-lane road for most of its length. The final stretch inside the national park transitions to compacted gravel, winding through lenga beech forest before revealing the glacier's massive blue face. Elevation at the glacier's edge is approximately 200 m (656 ft) above sea level, though the ice itself rises to over 60 m (197 ft) above the surface of Lago Argentino.
Road Conditions and Practical Information
The road is generally in good condition and accessible year-round, though conditions can change dramatically depending on the season. Patagonian wind is the primary hazard — gusts regularly exceed 80–100 km/h (50–62 mph), particularly between November and March. Crosswinds can affect vehicle stability, especially on higher and more exposed sections of the road. Low-clearance vehicles are not recommended for the gravel section inside the park.

What to Expect Along the Route
Leaving El Calafate heading west, the road cuts through the Patagonian steppe — a vast, almost treeless plateau where guanacos graze freely alongside condors circling overhead. The landscape is austere and immense, with the Andes appearing as a white-capped wall on the horizon.
As the road enters Los Glaciares National Park, the terrain shifts dramatically. The steppe gives way to native forest: gnarled ñire and lenga beech trees, bent permanently by the wind. On clear days — which are common in summer — the turquoise waters of Lago Argentino, the largest lake in Argentina, become visible to the south. The lake covers 1,466 km² (566 sq mi) and its channels carry enormous icebergs calved from the glacier.
The first view of Glaciar Perito Moreno appears suddenly around a final curve in the road — a wall of white and blue ice that stretches 5 km (3 mi) wide and advances at a rate of approximately 2 meters per day. It is one of the few glaciers in the world that is not retreating. The sight is genuinely overwhelming and unlike anything else in Patagonia.
Exploring Beyond the Drive
For travelers looking to go beyond the viewpoints, the glacier offers a range of activities including guided ice trekking, boat tours along the glacier face, and multi-day expeditions into the surrounding national park. Booking a structured excursion from El Calafate is the most common approach for visitors who want guided access to the glacier and the broader region. Experienced local operators offering Patagonia adventure tours provide transport from El Calafate, guided walks on the ice, and access to the most dramatic viewpoints that independent visitors often miss.
Getting There
El Calafate is served by Malvinas Argentinas International Airport (FTE), with regular flights from Buenos Aires (EZE/AEP) taking approximately 3 hours. Rental cars are available at the airport and in town. The drive to the glacier is straightforward — RP11 is well signposted and there are no significant navigational challenges outside of weather conditions.
For those without a vehicle, organized day tours from El Calafate depart daily during the high season and include return transfers, entrance fees, and guided access to the walkways.
