Official site
Las Leñas is one of the largest and most famous ski resorts in the
South America. It is located 43 mi (70 km) North-west of Malarque at
a elevation of 3,430 m (11,253 ft). Las Lenas Ski Resort is an
extensive ski resort that covers a total area of 17,500 hectares
(43,000 acres). It lies at an elevation ranging from 2,240 meters
(7,350 feet) at its lowest point to 3,430 meters (11,250 feet).
There are over 40 runs of different ski level. The longest run in
Las Lenas Ski Resort measures at more than 7 km (4.3 miles).
Las Lenas Ski Resort is open during winter months that in the
Southern Hemisphere correlates between mid June and mid October.
There are plenty of tourist accommodations in the region ranging
from high priced hotels to a cheaper hostels. During summer months
Las Lenas Ski resort is open for hiking, horse riding, mountain
biking, mountain climbing as well as other activities.
Best Time to Visit
Ski season typically runs from mid-June into
late September (sometimes early October), depending on snowfall. July
and August are peak months for the best coverage and consistent
operations, though they bring the biggest crowds and highest prices.
Late July through August often offers the strongest snow; early June and
September can be quieter and cheaper but more variable. The 2026 winter
season closed on 28 September.
Summer (roughly late December to
March/April) transforms the valley into an adventure destination with
trekking, horseback riding, mountain biking, rafting, ziplines, and
more. Hotel Piscis and related services often reopen around late
December. Current time (mid-October) is off-season for skiing but ideal
for planning the next winter or checking emerging summer packages.
How to Get There
Access is remote, so plan logistics carefully.
Air: Fly into San Rafael (AFA) on Aerolíneas Argentinas from Buenos
Aires (about 2 hours), then transfer ~2 hours by road. Mendoza (MDZ) is
another option with longer ground transfers (~4–6+ hours). Charter
flights from Buenos Aires or São Paulo to Malargüe sometimes run in peak
winter.
Bus: Overnight sleeper buses from Buenos Aires (charter
services on Fridays/Sundays during ski season, ~11–14 hours) or regular
services to San Rafael/Malargüe, then local transfers (Iselin and
others).
Car: ~11–13 hours from Buenos Aires via routes including
RN7/RN188/RN143/RN144 and RP222; ~6 hours from Mendoza. In winter, snow
chains are mandatory on RP222 and other mountain roads—rent or buy them
in advance, check road status with Gendarmería or local reports, and
avoid driving in whiteout or heavy snow if inexperienced. Fuel up before
the final mountain stretch and carry water, food, and warm layers.
Staying on-mountain in the Valle de Las Leñas village is strongly
preferred for ski-in/ski-out convenience and avoiding daily transfers.
Accommodation
The self-contained village offers hotels,
apart-hotels, and limited other options—all bookable well ahead for
July–August. Notable properties include:
Hotel Piscis: Often
rated the top choice, with spa, heated pools, kids club, casino (noted
as one of the highest-elevation casinos), and strong service.
Hotel
Virgo and Hotel Escorpio: Solid options with ski access, restaurants,
and family-friendly features.
Hotel Aries and Hotel Acuario: More
moderate; Aries is somewhat farther from the main village.
Apartments
and a hostel for budget or self-catering stays.
Many packages
include breakfast and dinner. Check-in is typically mid-afternoon;
lockers are available if you arrive earlier. Small supermarkets and a
mall (Piramid) exist for basics.
Skiing, Snowboarding, and Winter
Activities
Las Leñas is renowned for intermediate-to-expert terrain
and freeride/off-piste skiing. Roughly 15% beginner, 45% intermediate,
35% advanced, and 5% expert marked runs, plus extensive unmarked
terrain. There are around 14 lifts serving dozens of runs (figures vary
slightly by source; longest continuous run is about 7 km). The legendary
Marte chair accesses steep expert bowls and chutes but is wind- and
weather-sensitive and often closes. Other key areas include Apolo,
Neptuno, and Vulcano. Night skiing is available on lower
beginner/intermediate terrain.
Helmets are required. The ski school
offers lessons in multiple languages, kids programs (including very
young children), and guided off-piste or cat-skiing options. Rentals
(skis/snowboards, clothing) and a snow park are available. Beginner
areas are near the base with gentle Poma lifts. The mountain is
exposed—high winds or fog can shut upper lifts and change the day
dramatically. Cat-skiing is offered; heli-skiing is not.
Entry to the
resort grounds is free; costs are for lifts, rentals, and extras. 2026
high-season adult daily lift tickets were around 180,000 ARS (lower in
shoulder periods; multi-day and package deals exist). Rentals started
from roughly 65,000 ARS for adults. Prices fluctuate with exchange rates
and promotions—always check laslenas.com.
Summer Activities
The valley offers trekking (various difficulty levels, including
family-friendly routes), horseback riding (1 hour to full day), mountain
biking and a bike park, rafting (class 2–3 sections on nearby rivers),
ziplines (including “Tirolesa del Grito”), climbing/rappel, chairlift
scenic rides, and more. A new mountain lodge in Valle Hermoso has been
highlighted. Hotel Piscis often runs half-board packages with
activities. Nearby Malargüe and the RP222 corridor add hot springs (Los
Molles area), more hiking, and nature.
Practical Visiting Tips
Altitude: Base is already high. Arrive a day early to acclimatize. Stay
hydrated, limit alcohol initially, and watch for headaches or fatigue.
Sunscreen (high SPF), goggles/sunglasses, and lip protection are
essential year-round due to intense UV reflection off snow or rock.
Weather and clothing: Winter daytime highs often around −5 °C to +5 °C,
with colder nights and storm days well below −10 °C. Dress in layers
(base, mid, waterproof shell); avoid cotton/jeans. Rent technical gear
if needed. Summer is milder and dry.
Safety: Off-piste terrain
includes cliffed-out chutes—know your routes or hire a guide and carry
avalanche gear (beacon, shovel, probe) with a partner. Check daily
mountain reports. Road closures happen in winter storms. Travel
insurance with sports coverage is essential (and often required for
entry to Argentina).
Costs and logistics: On-mountain prices are
higher; self-catering apartments help. Book early for peak weeks.
Spanish is primary, but English is spoken in tourist services. Argentine
pesos or cards are used; carry some cash.
Après-ski and food: Hotels
have restaurants; limited standalone options include casual spots and
bars (UFO Point is a long-standing slopeside favorite). Mendoza Malbec
and asado are highlights. Small shops sell souvenirs and basics.
Nearby: Malargüe for services and more outdoor options; the broader
Mendoza region for wine and city culture if combining trips.
Location and Setting
The resort occupies a remote, elevated valley
in the central Andes, about 70–95 km west of Malargüe, 200–340 km from
San Rafael, 340–450 km from Mendoza city, and roughly 1,200 km from
Buenos Aires. Access is via paved Provincial Route RP 222, which
branches west from RN 40 and passes scenic spots such as Laguna de la
Niña Encantada and Pozo de las Ánimas. The valley is relatively
isolated, with a self-contained, purpose-built resort village of hotels
and facilities at the base and little permanent settlement otherwise.
Immediately west lies the even higher and less accessible Valle Hermoso,
source area of the Río Grande (locally called Tordillo) and home to
thermal springs (Valle Hermoso and Sosneado). The surrounding peaks form
a dramatic natural amphitheater; many exceed 4,000 m, including Cerro
Las Leñas (around 4,351 m) nearby.
Elevations and Vertical Relief
Base elevation: approximately 2,240 m (7,350 ft)
Mid-mountain: around
2,835 m
Ski summit: 3,430 m (11,250 ft)
Vertical drop: about
1,190–1,230 m (one of the larger in South America)
This places
Las Leñas among Argentina’s highest ski areas. The terrain is
predominantly high-alpine and treeless at the upper elevations, with
steep faces, couloirs, and open snowfields that favor powder and
off-piste skiing. The legendary Marte sector (accessed by a high
chairlift) offers steep, high-altitude lines and long vertical descents.
Reported skiable terrain figures vary by source: marked/groomed trails
are often listed in the range of a few dozen (roughly 27–52) totaling
tens of kilometers, while the broader accessible area (including
off-piste) is frequently given as around 17,500 hectares (43,000 acres).
The longest continuous descent is about 7 km (combining runs such as
Apolo–Neptuno–Venus). There are typically 14 lifts.
Hydrology and
Landscape
The valley contains the headwaters of the Río Salado de
Malargüe, which connects to the Río Atuel system and also relates to the
endorheic basin of Laguna Llancanelo. The landscape is high-Andean: open
slopes, volcanic and sedimentary rock, limited vegetation at altitude,
and a stark, treeless character above roughly the mid-mountain zone. The
name “Las Leñas” relates to the local shrub Adesmia pinifolia
(historically called “leña amarilla” or yellow firewood). Nearby
features include the transition toward Patagonian steppe influences
lower down and more rugged cordilleran terrain higher up.
Climate
Las Leñas has a warm-summer Mediterranean continental climate (Köppen
Dsb), atypical for the Southern Hemisphere. Summers are moderate and
very dry; winters are cold and snowy, with the bulk of precipitation
falling as snow from roughly June to October. High elevation produces
relatively dry powder. Average annual snowfall figures vary widely by
source and elevation (commonly cited in the 350–600+ cm range at upper
levels, with higher accumulation at the summit than at the base).
Snowmaking (dozens of cannons) supplements natural snow. The ski season
generally runs mid-June to early/mid-October.
