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.
Overview
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.
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.
Hazard Assessment
The high pass is immensely exposed. Searing sun and freezing, gale-force Patagonian winds can strike in the same hour.
Walking across loose volcanic ash is exhausting and slipping is common.
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.
Stage Breakdowns
La Picada to the Pass
Gradual long climb departing the forest and entering the desolation zone of black sand and rocky rubble.
Descent
Sliding down the ash fields, looking over Lake Todos los Santos.

Technical Profile
Vertical Ascent Profile
A steady, exhausting climb through shifting volcanic ash toward the pass, followed by a descent back.
Terrain Characteristics
Located near Puerto Varas in Chile's Los Lagos Region. Exposed walking over loose volcanic ash.
A measured physical load of 800m ascent requires steady pacing but remains accessible for active hikers.

Route Questions
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.
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.
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.
Can I bike the Paso Desolación?
Yes, it is a very popular, albeit challenging, mountain biking route. Hikers should stay aware of descending cyclists.
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.
