From the Estancia Los Huemules visitors' centre, the path follows the Diablo River through native forest and crosses hanging bridges. Near the lagoon, it leaves the forest for rockier terrain and reaches Laguna Diablo below Cagliero Glacier. Puesto Cagliero is beside the lagoon. Laguna Azul can be combined with this hike, but it is a separate route and not part of this record.
About the moderate grade: Half to full day with sustained climbs. Up to ~800 m of gain, sections of loose rock or wind exposure. Requires solid base fitness.

Hike it right
Know before you go.
Patagonia rewards prepared hikers. A few specifics for this trail — so you, and the trail, both come back in good shape.
Permit required
Arrange your permit before you travel — checkpoints do verify, and quotas protect the trail for everyone.
Weather-window route
In high wind or heavy rain, postpone. Check the forecast above before committing — the mountain will still be there tomorrow.
Visibility matters
The views are the point of this trail. In low cloud, save it for another day and pick a forest or lake walk instead.
Safety notes
This is a private reserve with a fee, entry hours, and a daily-visitor quota. Confirm current reservation, fee, weather, and access conditions directly with the reserve before travel.
What to pack
The Patagonia day-hike checklist — layers first, wind always.
For this trail: Wear hiking boots and bring water, food, a warm layer, rain protection, and sun protection. Arrange transport for the 17 km approach from El Chaltén.
Patagonia can cycle through four seasons in one afternoon. Dress in layers you can add and shed fast — wind is the defining factor.
- Base layer — Synthetic or merino, never cotton — it must wick sweat and dry fast.
- Mid layer — Fleece or a light insulated jacket for breaks and summit wind-chill.
- Outer shell — Wind- and waterproof jacket. This is the one piece you should never skip.
- Hiking pants — Quick-dry. Add thermal tights underneath in shoulder season.
- Warm hat & gloves — Even in January — exposed ridges are cold when the wind picks up.
- Sun hat or cap — Patagonian UV is strong and shade is rare above the treeline.
- Spare merino socks — Wet feet end hikes. A dry pair weighs nothing.
