On the Living Ice: Minitrekking Perito Moreno’s Blue Labyrinth
Step onto a living glacier—two hours on ice within a full-day Patagonian adventure
You set off before the light softens over the lake, the town of El Calafate still folding into sleep behind you. The bus threads a serrated coastline of lenga forest and wind-polished stones, and at Bajo de las Sombras port the air tastes of cold water and old snow. A small boat slips across the canal, and the glacier appears: a hulking wall of blue striations and fractured ivory that seems to breathe. When a distant slab calving thunders, the whole valley answers. That first moment—when the boat pulls into the shadow of the ice and you feel the glacier’s scale in your chest—is why people come here.
Trail Wisdom
Arrive early and layer up
Morning departures are calmer and cooler—wear moisture-wicking base layers and a windproof shell for variable conditions.
Bring lunch and water
The activity does not include food; pack a high-energy lunch and at least 1–2 liters of water in an insulated bottle.
Use sturdy waterproof boots
You’ll fit crampons over your boots—choose ankle-supporting, waterproof footwear for comfort and safety.
Protect your eyes and skin
Glare from ice is intense—bring sunglasses with UV protection and SPF 30+ sunscreen.

Seasonal Guide
spring
Best for: Fewer crowds, Wildflower blooms near trailheads
Challenges: Unstable weather, Cold snaps with late snow
Spring (Sep–Nov) brings melting snow and variable conditions—great for quieter trails but pack for both sun and sleet.
summer
Best for: Long daylight, Calmer weather windows
Challenges: Higher visitor numbers, Strong sun and wind
Summer (Dec–Feb) is the optimal season for stable weather and reliable boat crossings—the busiest time for tours.
fall
Best for: Golden lenga forests, Fewer tourists
Challenges: Cooling temperatures, Shorter daylight
Fall (Mar–May) offers dramatic color and reduced crowds, but expect colder afternoons and earlier returns to town.
winter
Best for: Ice colors more pronounced, Unique low-light photography
Challenges: Reduced services, Very cold temperatures and possible closures
Winter (Jun–Aug) is quiet and stark; some services may be unavailable and conditions can be harsh—check availability.
