Paso de las Nubes, Mountain pass in Río Negro Province, Argentina
Paso de las Nubes is a mountain pass in Nahuel Huapi National Park that connects Pampa Linda with Frias Lake, winding through varying elevations and landscapes. The route passes through forests, open meadows, and alpine terrain that changes with the seasons and weather conditions.
The pass served as a crossing route between Argentina and Chile through the Andes, functioning as an important connection for travelers between the two countries. The route has a long history as a passage for people moving through the mountain region.
Local hiking communities maintain the traditions of multi-day trekking through this pass, sharing knowledge about weather patterns and trail conditions with new generations.
The hike requires several days and should be planned with appropriate gear for changing weather conditions. Visitors should prepare for steep sections and possible snow patches, particularly during colder months.
Cloud formations flowing from Chile through the valley create a special moisture environment that shapes the vegetation and ecosystem. This natural moisture supply allows plant species to thrive that are less common in other parts of the park.
