Beneath the Watchful Cone: Walking Lanín National Park
Hike, paddle and drive the volcanic spine of Argentine Patagonia—where lenga forests meet lake-blue horizons.
The road out of San Martín de los Andes climbs and unfurls like a map you finally understand. Lenga forest presses in on both sides—trunks the color of old paper, ferns brushing your knees—and the air is thin with resin and melted snow. When the trees break, a cone takes the stage: Lanín Volcano, a clean, volcanic silhouette that feels carved for postcards. Lakes mirror the sky—blue so sharp it seems to cut—and the wind moves like a critic, shifting moods in a single gust. This is Lanín National Park: a patchwork of Andean forest, ice-polished rock and water bodies that dare you to slow down and look.
Trail Wisdom
Hire a local guide for reach and depth
A local mountain guide will match trails to your fitness and reveal cultural and ecological insights you’d miss alone.
Layer for sudden weather shifts
Start with a breathable base, an insulating midlayer and a waterproof shell—conditions flip quickly near the volcano.
Bring a refillable water bottle and filter
Facilities inside the park are sparse; filter-capable water lets you refill from clear streams and stay hydrated on longer routes.
Plan hikes for mid-morning to mid-afternoon
Weather and visibility are most reliable between 10am and 3pm; aim to be off exposed ridgelines before afternoon winds pick up.
