This route covers 12km return.It involves around 300m of cumulative elevation gain.
The route reaches roughly 250m at its highest point.
Technically, the Grey Glacier and Lago de Grey standard trail is non-technical. The walk is generally straightforward, with varying conditions depending on the immediate environment.
Overview
Technical Summary
Located inside Torres del Paine National Park in Chilean Patagonia. Starting with incredible views of Cuernos del Paine and Cerro Paine, the day hike to Grey Glacier and Lago Grey features stunning lake and mountain views throughout most of the trail.
The Calving Glacier. Approaching the massive wall of the Grey Glacier while bright blue icebergs drift across the milky-grey water is an unforgettable sight. The echoing crack of ice detaching from the face of the glacier into the freezing lake below is dramatic and often startling.
Hazard Assessment
The wind coming off the Southern Patagonian Ice Field across Lago Grey can be forceful, sometimes blowing hikers off their feet.
Even in mid-summer, the ambient temperature near the glacier drops significantly.
Route Summary
This is a scenic and highly accessible route.Check the local forecast and plan your schedule to allow ample time to enjoy the views.
Stage Breakdowns

Technical Profile
Vertical Ascent Profile
Relatively flat trail undulating alongside the lake with a short, steep rocky climb toward the final miradores.
Terrain Characteristics
Technically, the trail is non-technical, with minor rocky sections near the viewpoints.
The physical demand is defined by the 12km distance and local environmental conditions rather than vertical gain.

Route Questions
Can I do the Grey Glacier hike in one day?
Yes, but it is a long day. You must take the catamaran across Lago Pehoé to Paine Grande, hike to the viewpoints, and return in time for the last catamaran back to Pudeto.
Do I need technical equipment?
No technical gear is needed for the trail to the viewpoints. Trekking poles are highly recommended due to the strong winds, along with a heavy hardshell jacket.
Can I walk on the Grey Glacier?
Ice trekking requires booking a specific guided tour that departs from Refugio Grey. The standard trail only leads to observation points.
Is the trail difficult?
It is considered one of the easier segments of the W-Trek. It is mostly rolling terrain, with some rocky scrambling near the final viewpoints.
Do I need a reservation to hike this segment?
If you are only day-hiking and returning on the same day, you only need the park entrance ticket. If you plan to camp at Paine Grande or Refugio Grey, advance reservations are strictly required.
