Route Snapshot

This route covers 12km return.It involves around 800m of cumulative elevation gain.

The route reaches roughly 1,100m at its highest point. While the altitude is moderate, weather exposure and wind can make conditions feel more demanding than the elevation suggests.

Technically, the Paso Desolación (Desolation Pass) standard trail is non-technical. The primary difficulty is the sustained physical effort required or technical terrain features.

Technical Summary

Set within Chile's spectacular Vicente Perez Rosales National Park, the Paso Desolación (Desolation Pass) trek showcases the incredible, destructive power of the perfectly-conical Osorno volcano. The classic route runs point-to-point between La Picada and Petrohué; many hikers arrange transport at one end.

The Crux

Walking on Ash. The volcanic landscape gives the strong impression that you are hiking across the surface of Mars or the Moon, deeply contrasting with the vibrant alpine lakes and snowy peaks filling the horizon.

Ideal For
Comfortable hiking on loose, shifting terrain for extended periods. Good cardiovascular fitness is required for the constant upward slog in the ash.
Risk Level
Moderate technically, but severe weather-dependent endurance.
Why Choose This
Standard safety protocols and localized hazard assessments based on park regulations.

Hazard Assessment

What is the most dangerous section of the Paso Desolación (Desolation Pass)?
weather exposure

The high pass is immensely exposed. Searing sun and freezing, gale-force Patagonian winds can strike in the same hour.

Recommended Mitigation
Pack heavy windbreakers, thermal layers, and extreme UV protection sunscreen.View Hazard Classification Scale →
shifting terrain

Walking across loose volcanic ash is exhausting and slipping is common.

Recommended Mitigation
Wear hiking boots with ankle support to avoid sand filling your shoes. Use trekking poles.View Hazard Classification Scale →

The Expert Take

Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.

Route Questions

01

Can I reach the summit of Osorno Volcano on this trail?

No. The Paso Desolación trail traverses the flank of the volcano. Reaching the actual summit requires technical mountaineering gear (crampons, ice axes, ropes) and a certified guide.

02

Is there shade on the trail?

Only in the first and last forest sections. The vast majority of the hike across the pass is completely exposed to the sun and wind.

03

What happens if it rains?

The volcanic ash can become heavy and muddy, and the wind is often severe. The pass is not recommended during heavy storms due to zero visibility.

04

Can I bike the Paso Desolación?

Yes, it is a very popular, albeit challenging, mountain biking route. Hikers should stay aware of descending cyclists.

05

Do I need a 4x4 vehicle to reach the trailhead?

No, the road to Petrohué (one end) is paved. Accessing La Picada (the other end) might require driving on gravel, but standard clearance vehicles are usually sufficient in summer.
