Cerro Castor: a ski resort at the end of the world

When summer vacations are in full swing in the Northern Hemisphere, the winter season opens in Ushuaia. Cerro Castor is the southernmost ski resort in the world, just 26 kilometers from downtown Ushuaia. It's the only resort in Argentina with the longest season — from late June to early October, sometimes into mid-October. The national teams of Canada, the US, and Norway come here to train before their own winter season.

Where Cerro Castor is

The resort sits in the Tierra Mayor valley, on the eastern slope of the Castor massif. About 30 minutes by car from Ushuaia airport along National Route 3 toward the Beagle Channel. The road is paved and is cleared regularly even in deep winter.

The main quirk of the location is the low treeline. At 54°45' south latitude, woody vegetation (southern beech, nothofagus) ends at just 600 meters. That means most of the runs are above the forest zone — on open slopes with views of the Beagle Channel and the mountains of Tierra del Fuego.

Technical specs

For those who like numbers — the full resort profile:

Runs by difficulty:

• Green (beginner) — 17%
• Blue/red (intermediate) — 53%
• Black (advanced) — 30%

Why the snow here is special

Tierra del Fuego's climate is subantarctic oceanic. In winter the temperature holds at around -3 to -8 °C, ideal for dry powder. Humidity comes off the ocean, but because of the low temperatures the precipitation falls as snow, not as the rain-snow mix you get in warmer mountains.

Average snowpack depth at peak season (August–September) is 80–150 cm. The snow season is stable, with no thaws, because the sun stays low on the horizon and doesn't warm the slopes.

Season and best time to ski

Official opening is usually late June (between the 20th and 30th); closing is in the first ten days of October. Inside the season:

• Late June – July — early start, the snow base is building, upper runs may still be closed. Prices are lower.
• August — peak season, best snow, all runs open. Overlaps with Argentine winter holidays (second-third week of July), more people.
• September — a great time: days are longer, snow is still good, the sun is higher. The best balance of quality and comfort.
• Early October — season closing, mild weather, ski pass deals.

For trips with Magellania we usually recommend August–September.

Lifts and infrastructure

The lift system has a capacity of about 9,000 people per hour, which for a resort this size is comfortable — there are almost no lift lines on weekdays.

• Chairlifts (5) — the main ones, take you up to the mid and upper levels
• Surface lifts (4) — for the learning zone and short climbs
• Magic Garden — a separate zone for the smallest skiers, with a short tow conveyor and gentle slopes

The base station is a modern complex with rental, school, lockers, café, and shop. Parking is free.

What's on the mountain

The resort has 3 restaurants:

1. Bardo (base) — the main restaurant, Argentine food, steaks, empanadas, pasta
2. Refugio Schuss (mid-mountain) — a small wooden house with a fireplace, light meals, mulled wine
3. Morena (top station) — a café with panoramic views, snacks, hot drinks

Average bill for lunch — $15–25 per person. Free Wi-Fi at the bases, locker rental ($5/day).

Transport from Ushuaia

The resort runs a free shuttle from town for ski pass holders. Buses leave from a central point (next to the tourist office on Avenida Maipú) in the morning (8:00–9:30) and return in the afternoon (16:30–17:30). The schedule shifts with the season; current schedule on the Cerro Castor website.

Alternatives:

• Taxi/transfer — $25–40 one way
• Car rental — convenient if you plan several days of skiing in a row
• Your own car — parking at the resort is free and large

Day program: a typical scenario

08:00 — leave Ushuaia by shuttle or car 08:30 — arrival, pick up rental gear, change 09:30 — lifts open, first runs on the lower trails 12:30–13:30 — lunch at one of the on-mountain restaurants 14:00–16:00 — skiing the upper runs 16:30 — last runs, return rental 17:00 — return shuttle to Ushuaia

Who Cerro Castor is right for

Families with kids — great. Magic Garden zone, ski school, free passes for the youngest, safe gentle runs.

Beginners — yes. Professional instructors (Spanish and English), 17% green runs, a dedicated learning area.

Intermediate — heaven. 53% of runs are blue and red, plenty of room, varied terrain.

Experts and freeriders — there are black runs and off-piste routes with a guide. Not the Alps in scale, but enough for a few days. Off-piste is allowed in designated zones.

Pro training — Cerro Castor is known as a training base for Northern Hemisphere national ski and snowboard teams. When they're in their off-season, here it's peak winter.

What to bring

If you bring your own gear — standard ski kit. If you rent — you only need warm clothes and a basic set:

• Membrane jacket and pants
• Thermal base layers (2 layers in strong wind)
• Fleece or insulation layer
• Warm socks (proper ski socks)
• Gloves or mittens
• Hat/balaclava, neck gaiter
• Ski goggles — mandatory, UV at altitude is strong
• SPF 50+ sunscreen and lip balm

Skiing + Ushuaia: how to combine

Cerro Castor isn't a closed-loop resort like European ski villages. Most guests stay in the city of Ushuaia (hotels, restaurants, nightlife) and drive up to the mountain for the day. That expands the program a lot:

• 2–3 days of skiing at Cerro Castor
• 1 day — Beagle Channel cruise (it runs in winter; seals and views are different from summer)
• 1 day — snowmobiles in Tierra Mayor
• 1 day — dog sledding or cross-country skiing in the valley
• Evenings — city restaurants, fish, crab, Argentine wine

The result — a full winter week in Tierra del Fuego.

Safety and prep

The resort is well organized: slopes are groomed overnight, patrol works during skiing hours, runs have emergency posts. Travel insurance with ski sports coverage is mandatory (most international policies include it for a small premium).

Altitude sickness isn't a risk — the elevations are low. But the weather can shift fast: in an hour the sun can give way to dense fog with 50-meter visibility. Watch for announcements about closing the upper runs.
