Argentina Perito Moreno Glacier Walk
Walking across Argentina’s Perito Moreno Glacier immerses you in a dynamic ice landscape where towering seracs and deep blue crevasses reveal ancient frozen history. This Patagonian adventure combines accessible trekking with breathtaking scenery, suitable for various fitness levels when properly prepared with crampons and expert guides. Our guide covers essential planning, seasonal timing, and insider tips to maximize your glacier experience while respecting this fragile environment.
Essential Glacier Information
Perito Moreno Glacier spans 97 square miles within Los Glaciares National Park, part of the Southern Patagonian Ice Field that feeds 47 major glaciers. Unlike most glaciers worldwide retreating due to climate change, Perito Moreno maintains equilibrium through unusual ice accumulation patterns. This stability creates spectacular calving events where house-sized ice chunks crash into Lake Argentino.
The glacier advances up to 7 feet daily while losing equivalent mass through calving, creating a constantly changing landscape perfect for ice trekking. Its accessibility via wooden catwalks and proximity to El Calafate make it Argentina’s most visited glacial attraction. UNESCO designated this region a World Heritage Site in 1981, protecting both natural beauty and scientific significance.
Geological Formation and Features
This river of ice originates 11,000 feet high in the Andes, flowing eastward for 19 miles before terminating in Lake Argentino’s southern arm. The glacier’s distinctive blue coloration comes from dense ice absorbing all light spectrum colors except blue, which it scatters back. Ice depths reach 558 feet at the terminus, with some sections extending 2,300 feet below water level.
- Ice formations include deep crevasses, seracs (ice pillars), and moulins (vertical shafts) that require expert navigation during walks
- The glacier’s unique advance pattern creates a natural dam across the lake, causing periodic ruptures that draw international scientific interest

Why This Glacier Stands Out
Perito Moreno remains one of only three Patagonian glaciers not retreating, offering reliable trekking conditions year-round compared to diminishing ice fields elsewhere. Its massive scale becomes apparent when standing before the 240-foot-high ice wall spanning 3 miles across the lake. The thunderous sound of calving ice provides constant auditory reminders of the glacier’s active nature.
Modern infrastructure includes 2.5 miles of elevated walkways with multiple viewing balconies positioned for optimal photography angles. These facilities minimize environmental impact while maximizing visitor experience across different mobility levels. Rangers monitor conditions continuously, closing sections during significant calving events for safety.
Conservation and Climate Context
Los Glaciares National Park implements strict visitor limits and guided access requirements to preserve the glacier’s delicate ecosystem. The Argentine National Parks Administration records detailed ice movement data, showing stable mass balance despite regional warming trends. Your visit directly funds conservation through park entrance fees and regulated tour operator permits.
Scientists attribute Perito Moreno’s stability to unique bedrock topography that channels ice flow efficiently from accumulation zones. Climate models project maintained equilibrium through mid-century, making it a rare climate-resistant destination for glacier tourism. Responsible visitation supports ongoing research and protection efforts.
Planning Your Perito Moreno Glacier Walk
Successfully experiencing the Perito Moreno Glacier walk requires strategic timing between October and April when weather permits safe ice trekking and transportation operates reliably. Early morning departures from El Calafate beat afternoon winds while maximizing photography light conditions across the ice fields. Reserve guided tours 2-3 months ahead for peak season visits between December and February.
Physical preparation should include cardiovascular conditioning for 5-7 hours of activity at altitudes between 600-1,200 feet above sea level. While not technically demanding, the trek demands steady footing and moderate endurance for navigating variable ice surfaces. Tour operators provide all specialized equipment including crampons, helmets, and harnesses for added safety.
Budget considerations should include park entrance fees, transportation from El Calafate, and the mandatory guided glacier walk experience. Combination tours often offer better value by including boat excursions and walking platforms alongside the ice trekking component. Travel insurance covering adventure activities is essential given changeable Patagonian weather conditions.

Best Time to Visit Perito Moreno Glacier
Peak season runs December through February when temperatures range 50-68°F (10-20°C) with up to 17 hours of daylight for extended exploration. These summer months offer the most reliable weather but attract largest crowds, requiring advance bookings for accommodations and tours. Shoulder seasons in October-November and March-April provide milder conditions with 41-59°F (5-15°C) and reduced visitor numbers.
Winter visits from May to September see temperatures dropping to 23-41°F (-5 to 5°C) with limited tour availability and potential road closures during storms. The glacier remains accessible year-round via viewing platforms, but ice trekking operates primarily October through April. For photography, March offers spectacular light angles with autumn foliage contrasting against blue ice.
Budget Planning and Costs
Anticipate these expense tiers based on comfort level and included amenities during your Patagonian glacier adventure.
Essential Preparation Checklist
Packing should prioritize layered clothing including waterproof outer shell, insulating mid-layers, and moisture-wicking base layers suitable for rapid weather changes. Sturdy hiking boots with ankle support prove essential for rocky approaches before switching to provided crampons on ice. Technical gear like ice axes remains unnecessary for standard walks but included in advanced trek options.
Documentation needs include passport for park entry, credit cards for incidental purchases, and printed tour vouchers since cellular service remains unreliable near the glacier. Book accommodations in El Calafate 3-4 months ahead for December-February visits, with cancellation policies accommodating weather disruptions. Health preparations should account for sun protection at high altitudes and motion sensitivity during boat crossings.
Top Attractions and Activities
Beyond the iconic glacier walk itself, Los Glaciares National Park offers diverse experiences showcasing Patagonia’s dramatic landscapes and unique ecosystems. Boat tours provide unparalleled perspectives of the 240-foot ice wall from water level, often witnessing spectacular calving events.
