Las Leñas

🏔️ History
Las Leñas is Argentina's highest and most technical ski resort, and a global benchmark for high-mountain skiing in the Southern Hemisphere. It opened in 1983 in the Valle de Las Leñas, 70 km from Malargüe (Mendoza), deep in the heart of the Argentine Andes. Its extreme terrain — accessible from the legendary Marte chairlift (3,430 m) — has made it a pilgrimage destination for freeriders and expert skiers worldwide. Every season, the dry, light Andean powder draws professionals in search of impossible descents and untouched off-piste lines.

☀️ Best days
July and August are the prime months. Snow falls regularly and Andean powder — dry and ultralight — can linger for days in chutes and north-facing slopes. The first days after a good storm are the most sought-after: the off-piste terrain is completely refreshed and visibility is usually excellent, thanks to the high-pressure systems that dominate Mendoza winters.

🚫 Days to avoid
Argentine winter school holidays (last two weeks of July) spike occupancy across the resort and the most accessible pistes become crowded. Strong winds — a hallmark of Las Leñas — can close the Marte chairlift for days at a time, so always have a backup plan. August weekends with good forecasts fill up accommodation fast.

💡 Community tip
The most practical access is from Mendoza city (330 km) or San Rafael (200 km) by private vehicle or organized transfer. On-resort accommodation is ski-in/ski-out but pricey; finding options in Malargüe (70 km away) cuts costs significantly. For extreme freeride — the chutes, couloirs, and vertical walls off Marte — a certified local guide is essential: whiteout conditions and avalanche risk are real. Don't leave without skiing the Apolo–Neptuno–Venus run (7 km of continuous vertical descent), one of the longest linked descents in the world.
