Drake Passage: 7 Facts You Must Know, Crossing & Antarctica Travel Tips

The Drake Passage is one of the world’s most famous, powerful, and unpredictable stretches of ocean. Located between the southern tip of South America and the Antarctic Peninsula, it is best known as the sea route used by many expedition ships traveling to Antarctica.

For travelers, crossing these waters can be one of the most memorable parts of an Antarctic journey. The region is famous for strong winds, large waves, dramatic weather, seabirds, whales, and vast open-ocean scenery.

The passage is also extremely important to scientists because it forms a major gateway for the Antarctic Circumpolar Current (ACC), one of the most significant ocean currents on Earth.

In this complete guide, you will discover 7 essential facts about this remarkable waterway, including its location, why the crossing can be rough, how long it takes, its history, wildlife, weather, safety considerations, and practical Antarctica travel tips.

What Is the Drake Passage?

The Drake Passage is a large body of water separating South America from Antarctica.

It lies south of Cape Horn and north of the Antarctic Peninsula and South Shetland Islands. This waterway connects the Atlantic and Pacific sectors of the Southern Ocean, making it an important marine gateway.

It is approximately 850 kilometers, or about 530 miles, wide, although the exact measurement depends on which geographic points are used.

Because of its remote location, strong winds, powerful currents, and rapidly changing weather, the region has earned a legendary reputation among sailors, explorers, scientists, and Antarctic travelers.

1. Where Is the Drake Passage Located?

This famous waterway is located in the Southern Ocean, between the southern end of South America and Antarctica.

To the north are:

• Cape Horn
• Tierra del Fuego
• Southern Chile
• Southern Argentina

To the south are:

• South Shetland Islands
• Antarctic Peninsula
• Antarctic waters

Many Antarctic expedition cruises begin in Ushuaia, Argentina, a major departure point for voyages to the Antarctic Peninsula.

A typical expedition route may look like this:

Ushuaia → Beagle Channel → Southern Ocean crossing → South Shetland Islands → Antarctic Peninsula

Its geographic position makes the Drake Passage one of the principal maritime gateways for travelers heading to Antarctica by ship.

2. Why Is the Crossing So Rough?

One of the most common questions travelers ask is why this ocean crossing has such a rough reputation.

The answer involves a combination of powerful winds, ocean currents, open water, weather systems, and underwater geography.

Strong Westerly Winds

The Southern Ocean is known for persistent and powerful westerly winds.

At these high southern latitudes, there are relatively few large landmasses to slow or block weather systems.

As a result, winds can travel across enormous stretches of open ocean and contribute to the formation of large waves.

Antarctic Circumpolar Current

The Antarctic Circumpolar Current, commonly called the ACC, flows eastward around Antarctica.

It is the world’s largest ocean current by volume.

This relatively narrow ocean gateway carries a major part of the current.

Strong currents interacting with winds, storms, and seafloor topography can contribute to complicated and sometimes rough sea conditions.

Rapid Weather Changes

Weather conditions in the Southern Ocean can change quickly.

A relatively calm period may become windy and rough as weather systems move across the region.

This unpredictability is one reason no two crossings are exactly the same.

3. Drake Shake vs. Drake Lake

Travelers and expedition crews often use two informal expressions to describe conditions at sea: Drake Shake and Drake Lake.

What Is the Drake Shake?

The Drake Shake refers to rough sea conditions.

During a Drake Shake, travelers may experience:

• Large waves
• Strong winds
• Noticeable ship movement
• Difficult walking conditions
• Increased likelihood of seasickness

These conditions can make the journey challenging, particularly for passengers who are sensitive to motion.

What Is the Drake Lake?

The Drake Lake refers to unusually calm conditions.

During these periods, waves may be relatively small and ship movement less noticeable.

However, calm conditions are never guaranteed. A voyage may experience rough seas on the outward journey and much calmer conditions on the return crossing—or the opposite.

4. How Long Does It Take to Cross?

Most expedition ships take approximately two days to complete the crossing, although actual travel times vary.

Several factors can influence the journey, including:

• Ship speed
• Weather conditions
• Wave height
• Wind strength
• Expedition route
• Final destination
• Operational and safety decisions

Some crossings may be completed more quickly, while rough conditions may result in a slower journey.

During the voyage, expedition cruise operators often provide activities such as:

• Wildlife watching
• Photography sessions
• Antarctic history lectures
• Science presentations
• Safety briefings
• Expedition preparation

This means the journey can become an important part of the overall Antarctic experience rather than simply transportation between two destinations.

5. How Deep Is the Passage?

This part of the Southern Ocean is deep and geologically complex.

Much of its seafloor lies several thousand meters beneath the surface, although depth varies considerably throughout the region.

The underwater landscape includes:

• Ridges
• Basins
• Deep channels
• Submarine geological formations
• Other complex seafloor features

These underwater structures influence how ocean water moves through the area.

Scientists study the seafloor because underwater topography can affect the speed, direction, and mixing of the Antarctic Circumpolar Current.

6. History of the Drake Passage

The waterway is named after Sir Francis Drake, the English navigator and privateer.

During his circumnavigation voyage in 1578, severe weather pushed Drake’s ships south after they passed through the Strait of Magellan.

The voyage helped Europeans recognize that open water existed south of South America.

However, the human history of the wider region extends much further back than European exploration.

Indigenous peoples of southern South America lived in and navigated parts of the surrounding region long before European expeditions arrived.

Over subsequent centuries, these waters became associated with:

• Maritime exploration
• International shipping
• Scientific expeditions
• Antarctic research
• Modern expedition tourism

Today, the passage remains one of the most recognizable ocean crossings in the world.

7. Why Is This Passage Important?

This Southern Ocean gateway is important not only for Antarctic travel but also for oceanography and climate science.

Antarctic Circumpolar Current

The region is an important location for observing and studying the Antarctic Circumpolar Current.

The ACC flows eastward around Antarctica and connects the Atlantic, Pacific, and Indian Ocean basins.

Global Ocean Circulation

Water moving through this area contributes to larger ocean circulation processes that redistribute:

• Heat
• Freshwater
• Nutrients
• Carbon
• Oxygen

These processes connect the Southern Ocean with the wider global ocean and climate system.

Climate Research

Scientists study these waters to better understand changes occurring in the Southern Ocean.

Researchers may monitor:

• Ocean temperature
• Salinity
• Current speed
• Carbon
• Water circulation
• Long-term ocean and climate patterns

Its geographic position makes the region an important location for oceanographic research.

Wildlife During the Crossing

This vast stretch of open ocean may appear empty, but the region supports diverse marine wildlife.

Sightings vary according to season, location, weather, and simple chance.

Seabirds

The area is particularly famous for seabirds.

Travelers may encounter:

• Albatrosses
• Petrels
• Prions
• Skuas
• Shearwaters

Albatrosses are especially impressive because they can use Southern Ocean winds to glide over long distances with relatively little wing flapping.

Whales

Several whale species may also be encountered in or around the wider Southern Ocean and Antarctic region.

Possible sightings include:

• Humpback whales
• Fin whales
• Minke whales
• Orcas

Wildlife sightings are never guaranteed, but spotting whales can be a memorable part of an Antarctic expedition.

Penguins

Penguins are generally more likely to be seen near islands and Antarctic coastlines than in the middle of the open ocean.

Species commonly associated with the Antarctic Peninsula region include:

• Gentoo penguins
• Chinstrap penguins
• Adélie penguins

Weather and Climate

Weather in these southern waters is generally cold, windy, and highly changeable.

Even during the Antarctic summer, conditions can change rapidly.

Travelers may experience:

• Strong winds
• Cold temperatures
• Rain
• Snow
• Fog
• Large waves
• Sudden weather changes

The main Antarctic tourism season generally runs from approximately November through March, although exact operating periods vary by expedition and destination.

These months provide long daylight hours and conditions suitable for most Antarctic tourism operations.

However, rough seas can occur throughout the travel season.

Best Time to Cross the Drake Passage

There is no particular month that guarantees calm seas.

Most tourist crossings take place during the austral spring and summer.

November

November can feature extensive snow-covered landscapes and considerable sea ice in parts of the Antarctic region.

It may appeal to travelers interested in an early-season Antarctic experience.

December and January

December and January provide extremely long daylight hours in the Antarctic Peninsula region.

These are popular months for Antarctic travel and provide plenty of daylight for expedition activities.

February and March

Later in the season, whale activity can become a major attraction in parts of the Antarctic Peninsula region.

However, weather and sea conditions vary from voyage to voyage, so no month can guarantee a smooth crossing.

Is the Drake Passage Dangerous?

The Drake Passage can experience challenging conditions, but modern expedition vessels are operated by professional crews using navigation, forecasting, and safety systems.

Ships may use:

• Modern navigation technology
• Weather forecasting
• Satellite information
• Safety equipment
• Established maritime procedures

Captains can adjust a ship’s speed or route according to weather and sea conditions.

Passengers should always follow instructions from the captain and crew.

During rough weather, travelers should:

• Use handrails
• Wear secure footwear
• Avoid unnecessary movement
• Secure loose belongings
• Follow deck restrictions
• Listen to safety announcements

This remains a remote ocean environment, so preparation and responsible behavior are important.

Seasickness During the Crossing

Seasickness is one of the most common concerns among travelers planning this journey.

Possible symptoms include:

• Nausea
• Dizziness
• Headache
• Fatigue
• Sweating
• Loss of appetite

People respond differently to ship movement. Some passengers experience little discomfort, while others may be much more sensitive.

How to Reduce Seasickness

Some practical strategies may help travelers feel more comfortable:

• Stay hydrated
• Eat light meals
• Avoid excessive alcohol
• Rest when necessary
• Look toward the horizon
• Get fresh air when conditions and crew instructions allow
• Consider a cabin closer to the ship’s center, where movement may feel less pronounced

Travelers concerned about motion sickness should discuss appropriate prevention or treatment options with a qualified healthcare professional before departure.

Packing List for the Crossing

Packing properly can make the journey more comfortable.

Useful items may include:

• Waterproof jacket
• Windproof outer layer
• Thermal base layers
• Warm fleece
• Gloves
• Warm hat
• Comfortable footwear
• Sunglasses
• Sunscreen
• Camera
• Binoculars
• Reusable water bottle

Cameras, phones, bottles, and other loose objects should be secured when the ship is moving, particularly during rough conditions.

Can You Avoid the Drake Passage?

Yes. Travelers who do not want to spend multiple days crossing by ship can consider certain Antarctica fly-cruise itineraries.

These trips generally involve flying between southern South America and the South Shetland Islands region before joining an expedition ship.

Advantages of Flying

Flying may:

• Reduce time spent at sea
• Reduce exposure to rough sea conditions
• Shorten the overall journey

Disadvantages of Flying

Antarctic aviation is highly dependent on weather.

Poor visibility, strong winds, or other unsuitable conditions may result in flight delays or itinerary changes.

Fly-cruise itineraries can also cost more than traditional ship-based voyages.

Drake Passage vs. Strait of Magellan

These are two different waterways.

Drake Passage

This is a broad, open-ocean waterway between South America and Antarctica.

It is exposed to Southern Ocean winds, currents, and weather systems.

Strait of Magellan

The Strait of Magellan is a narrower waterway separating mainland South America from Tierra del Fuego.

It is more sheltered than the open Southern Ocean.

Historically, it provided ships with a navigable route between the Atlantic and Pacific Oceans without having to sail around Cape Horn.

Drake Passage vs. Cape Horn

Cape Horn is a famous headland in the Tierra del Fuego archipelago at the southern end of South America.

The passage extends south of the Cape Horn region toward Antarctica.

Cape Horn became famous in maritime history because ships traveling between the Atlantic and Pacific Oceans often faced difficult conditions when sailing around it.

The ocean crossing, meanwhile, covers a much broader body of open water separating South America and Antarctica.
