Few travel experiences compare to stepping onto a massive river of ice in the heart of Patagonia. Perito Moreno Glacier trekking is one of the most thrilling adventures in South America, offering visitors the rare opportunity to walk across a living, moving glacier surrounded by dramatic Andean scenery.
Located inside Los Glaciares National Park in Argentina’s Santa Cruz Province, the iconic Perito Moreno Glacier is one of the few glaciers in the world that is still advancing. If you're planning Patagonia glacier tours, this guide covers everything you need to know — from tour options and the best time to visit to what to expect on the ice.
Why Perito Moreno Glacier Is So Special
Stretching over 250 square kilometers and towering up to 70 meters above the water, Perito Moreno Glacier is a true natural wonder. It flows into Lago Argentino, creating a stunning contrast of white-blue ice against turquoise waters.
Unlike many glaciers worldwide, Perito Moreno continues to grow and periodically ruptures in spectacular ice-breaking events. This natural phenomenon makes it one of the highlights of Santa Cruz glacier excursions and a must-see destination in Argentine Patagonia.
Perito Moreno Glacier Trekking: What to Expect
Walking on the glacier isn’t just sightseeing — it’s an immersive adventure. Most tours begin from El Calafate, the main gateway town to the region.
After a short transfer to the national park, you’ll take a boat across Lago Argentino to reach the glacier’s edge. From there, professional guides equip you with crampons and helmets before leading you onto the ice.
During your Los Glaciares National Park glacier walk, you’ll:
- Walk across bright blue ice formations
- Explore crevasses and small ice caves
- Learn about glacier formation and movement
- Enjoy panoramic views of the Patagonian Andes
It’s an experience that feels both surreal and exhilarating.
Mini Trekking vs. Big Ice Trek Perito Moreno
There are two main glacier trekking options:
1. Mini Trekking (Beginner-Friendly)
- Duration on ice: ~1.5 hours
- Moderate physical level
- Suitable for most travelers
2. Big Ice Trek Perito Moreno (Advanced Adventure)
- Duration on ice: 3–4 hours
- More demanding physically
- Covers deeper glacier areas and dramatic ice formations
The Big Ice trek Perito Moreno is ideal for adventure seekers who want a more immersive experience. It’s one of the most rewarding Patagonia glacier tours for active travelers.
Lago Argentino Boat Tour Experience
Before stepping onto the ice, most itineraries include a scenic Lago Argentino boat tour. Cruising past floating icebergs while approaching the towering glacier face is an unforgettable moment.
The boat ride offers:
- Up-close views of the glacier wall
- Incredible photography opportunities
- A safe vantage point for witnessing ice calving
Even if you choose not to trek, the boat tour alone makes Santa Cruz glacier excursions worthwhile.
Best Time to Visit Perito Moreno Glacier
The Best time to visit Perito Moreno Glacier is during the Southern Hemisphere summer:
- November to March – Warmer temperatures, longer daylight hours, and ideal trekking conditions
- December to February – Peak season with the best weather but larger crowds
- Shoulder seasons (October & April) – Fewer tourists and cooler temperatures
Patagonia weather can change quickly, so layering is essential regardless of season.
How to Prepare for Glacier Trekking
To fully enjoy your Perito Moreno Glacier trekking experience:
What to wear:
- Waterproof hiking boots
- Warm layers (thermal base, fleece, windproof jacket)
- Sunglasses and sunscreen
- Gloves (even in summer)
Fitness level:
Moderate fitness is required. The terrain can be uneven, but guides ensure a safe pace for the group.
Why This Is One of the Best Patagonia Glacier Tours
Among all Patagonia glacier tours, walking on Perito Moreno stands out because:
- It’s accessible from El Calafate
- The glacier is stable and safe for guided trekking
- The scenery is among the most dramatic in South America
- It combines adventure, education, and breathtaking landscapes
Few destinations offer such direct interaction with a massive ice field in a protected natural setting.
Final Thoughts

From the dramatic ice walls rising from Lago Argentino to the crunch of crampons underfoot, Perito Moreno Glacier trekking is truly a once-in-a-lifetime experience.
