We lead expeditions to Mount Vinson, climbing to 4,892 m in the extreme polar climate of Antarctica.

At a glance

Trip overview

We organize and lead expeditions to Mount Vinson, the highest peak in Antarctica at 4,892 m above sea level. While physically lower than the highest summits in other ranges, this mountain presents severe environmental challenges, including sub-zero summer temperatures and powerful polar winds that generate extreme wind chill.

Our team coordinates every operational detail, starting from Punta Arenas in Chile through to the Ilyushin flight into Union Glacier and onward to Vinson Basecamp. We build comprehensive acclimatisation periods into our schedule, allowing our climbers to adapt safely to the thin polar air and physical demands of glacier travel.

This expedition suits experienced mountaineers who possess high levels of physical endurance and mental resilience. We maintain rigorous safety protocols throughout the climb, utilizing our extensive polar and high-altitude experience to manage logistics in one of the most remote regions on earth.

Day 9

Rest Day at Camp 2

Meals: B / L / D

We take a dedicated rest and recovery day at Camp 2, melting snow for hydration and eating high-calorie rations to maintain energy levels.

Day 10

Climb to Camp 3

Meals: B / L / D

We pack our gear and climb for approximately six hours from Camp 2 up to the high camp at Camp 3, preparing for our summit bid.

Day 11

Summit Day on Mount Vinson

Meals: B / L / D

We launch our summit push from Camp 3, traversing exposed ridges and steep ice fields to reach the highest point in Antarctica at 4,892 m before returning to camp.

Day 12

Weather Contingency Day

Meals: B / L / D

We hold this day in reserve at high camp to accommodate potential high winds or severe storms that frequently affect polar ascents.

Day 13

Descent to Basecamp

Meals: B / L / D

We pack up our high camps and retrace our route down the glacier, descending all the way back to the relative comfort of Vinson Basecamp.

Day 14

Flight to Union Glacier

Meals: B / L / D

We board the twin-otter aircraft at basecamp and fly back across the ice sheets to the main logistics hub at Union Glacier.

Day 15

Flight to Punta Arenas

Meals: B / L / D

We board the Ilyushin aircraft for the return flight north across the Southern Ocean, landing back in Punta Arenas, Chile.

Day 16

Weather Reserve Day in Punta Arenas

Meals: B / L / D

We maintain this reserve day to absorb any potential scheduling delays caused by marginal flying weather over the Antarctic ice sheet.

Day 17

Second Weather Reserve Day

Meals: B / L / D

We keep a second buffer day available in Chile to ensure our international travel connections remain secure despite polar weather volatility.

Day 18

Departure Home

Meals: B

We assist with final airport transfers in Punta Arenas as team members begin their respective journeys home.

Before you go

Good to know

Acclimatisation & Altitude

Although Mount Vinson reaches 4,892 m, barometric pressure at the poles is lower than at the equator, making the physiological effects comparable to a higher altitude elsewhere. We enforce a strict gradual ascent profile with dedicated rest and rotation days.

Extreme Weather Conditions

Summer temperatures at basecamp and higher elevations commonly hover around minus 30 °C, compounded by severe polar winds. Team members must be proficient in managing personal thermoregulation and recognizing early signs of cold injuries.

Physical Fitness Requirements

This expedition requires advanced cardiovascular endurance and strength. Participants must train extensively in pulling heavy sleds and carrying weighted backpacks over multi-hour training blocks prior to arrival.

Flight Contingencies

Intercontinental and polar flights depend entirely on visual meteorological conditions over the Southern Ocean and glacier runways. We build dedicated reserve days into our schedule to account for unavoidable weather holds.

Frequently asked questions

What physical preparation is needed for Vinson Massif?

Participants must build high levels of aerobic endurance and leg strength. We recommend months of weighted stair climbing, heavy pack marching, and sled-dragging practice.

How cold does it get on the mountain?

Summer temperatures frequently sit around minus 30 °C, and strong winds create severe wind chill factors that require specialized polar-grade clothing systems.

What happens if flights are delayed by weather?

Antarctic weather is notoriously volatile. We include dedicated reserve days in our 18-day schedule to absorb minor delays without disrupting your international connections.

Do I need to haul my own gear?

Yes. Team members pull a sled containing personal gear and supplies while also carrying a backpack containing daily essentials between camps.

What kind of oxygen support is used?

Mount Vinson is normally climbed without supplemental oxygen, relying instead on proper physiological acclimatisation and our structured rotational climb schedule.

Where does the expedition start?

The expedition formally begins in Punta Arenas, Chile, where we conduct our final gear checks before boarding the Ilyushin flight south.
