Backpacking in Paso de las Nubes
👍 Recommendedhike ranked #7
By Johan Kruseman 🇳🇱 | Updated September 4, 2026

Your boots slide on wet boardwalk, pack straps biting your shoulders, while the roar of the Frías River drowns out your thoughts and the glacier wind cuts straight through your sweaty shirt. Then the clouds rip open for a second and you catch it: the ice of Tronador glowing above the Paso de las Nubes, deep in Nahuel Huapi National Park, between Bariloche and the Chilean border in northern Patagonia, Argentina. This two-day traverse isn’t brutal, but it’s no lakeside stroll either: steady climbs, mud, and weather that flips fast. The payoff is huge—hanging glaciers, jungle-green forest, and a hut with a front-row seat to the icefall. It’s easier to reach by bus and boat than many Patagonian routes, and less punishing than, say, the Huemul Circuit, but it still feels wild enough that you earn every view.

  • Cloudline Summit (the Pass itself) — Hitting the col where the trail slices through the clouds is the whole reason it’s called Paso de las Nubes. You get true 360° Andean panoramas, dramatic cloud inversions at sunrise or late afternoon, and that rare feeling of walking above the weather. (Personal favorite — nothing beats coffee with that view.)
  • Lenga Beech Forests — The descent through lenga (Nothofagus) feels like a different hike: mossy trunks, filtered light and quiet birdlife offer contrast to the exposed high sections. It’s one of those stretches that soaks up sound and slows your pace, a peaceful counterpoint to the windy ridges.
  • Alpine Tarn Views — Small high-altitude lakes and tarns dot the basin below the pass; their turquoise pockets reflect jagged peaks and make excellent

  • Alpine Tarn Views — Small high-altitude lakes and tarns dot the basin below the pass; their turquoise pockets reflect jagged peaks and make excellent lunch stops. They’re photogenic, usually sheltered from the wind, and feel a lot more remote than the trail’s start suggests.
  • Wind-sculpted Ridges and Rock Bands — Narrow knife-edges, layered volcanic or metamorphic bands and patches of scree give the route a rugged, dramatic character you don’t get on forest-only tracks. The geology is obvious underfoot, and the exposures make for memorable route-finding moments.
  • Shepherding Tracks & Stone Cairns — You’ll notice old horse or shepherd trails, corrals and simple stone markers that speak to the human history of moving stock through these mountains. Those cultural traces break up the wildness and are a neat reminder that people have used this corridor for generations.

🌤️ When to go?Best time to hike the Paso de las Nubes


  • Weather: The best window is late spring to early fall (November to March). Days are mostly dry, but afternoons can bring sudden mountain showers. Avoid winter—snow and ice turn the trail into a slippery hazard.

  • Temperature: Expect highs around 20-25°C (68-77°F) in summer, dropping to 5-10°C (41-50°F) at night. Layering is key; mornings bite cold before the sun thaws the air.

  • Daylight Hours: Summer offers long days, up to 14 hours of light, giving you plenty of time to push through the trail without rushing. Shorter days in shoulder seasons mean earlier starts and quicker pace.

  • Crowds: Peak season (December to February) draws more hikers, especially weekends. For solitude, aim for November or March when the trail thins but conditions remain solid.

  • Seasonal Activities: Summer opens up side

  • Price Fluctuations: Accommodation and transport costs spike in peak summer. Booking early or traveling in shoulder months can save you a chunk of cash.


Pro-tip: Start your hike early in the day to beat afternoon storms and catch the golden light hitting the Andes—nothing beats that moment when the clouds part and the valley stretches wide below you.

🛡️ SafetyTraveler Safety Guide

The hike through Paso de las Nubes is a thrilling blend of challenge and reward. Expect weather that can shift on a dime; pack layers to adapt quickly. The trail is well-marked but steep in sections, so keep your footing steady and your pace consistent. Navigating rocky paths and occasional river crossings demands focus, but the effort pays off with breathtaking views of the surrounding peaks.
