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.

AI Insight: Optimal ratio of distance to elevation. Accessible for experienced intermediates.

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 12 km trek is considered one of the easier hikes of the multi-day Torres del Paine W trek, beginning at Camp Paine Grande. The mostly flat and shaded sections offer captivating scenery culminating in a short rocky climb near the end to witness the massive Grey Glacier calving into the glacial lake.

Mission Directive / X-Factor

“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.”
