Mount Erebus | Exploring Antarctica’s Most Active Volcano

Looking out across Antarctica's pristine white expanse, you'd never guess that a massive active volcano sits there, churning with molten lava beneath its icy exterior. Mount Erebus stands tall at 12,448 feet, and it's not just any volcano — it's the southernmost active volcano on Earth. 

You won't find another place on Earth quite like this — a volcano where fire and ice collide in the most spectacular way. While its surface is frozen solid enough to form incredible ice caves, just below your feet churns a lake of molten rock that reaches temperatures over 1000°C. It's like standing on nature's own thermostat gone wild.

Where is Mount Erebus?

You'll find Mount Erebus dominating the landscape of Ross Island in Antarctica, where it's been quietly (and sometimes not so quietly) going about its business for thousands of years. It is actually considered Antarctica’s second-highest mountain.

When you're studying a Mt Erebus map, you might notice it has company — three other volcanoes share the island, but they've since gone dormant. Erebus, on the other hand, isn't ready to retire just yet.

McMurdo Station

Mount Erebus sits approximately 25 miles from McMurdo Station, which functions as Antarctica's version of a small town. However, McMurdo Station is primarily a scientific research facility with highly restricted access. The station is exclusively accessible to those with authorised scientific contracts, research positions, or support staff roles. 

The general public cannot visit this area, as access is limited to individuals specifically contracted to work on official Antarctic programs.

During peak season, this research base thrives with up to 1,000 people, but that number drops dramatically when winter sets in. It's your jumping-off point for any Erebus adventure, and it has all the facilities you'd need before heading out into one of Earth's most extreme environments.

The Lava Lake

The most incredible part of Mount Erebus sits right at its heart — a lake of actual lava that never goes away. And we're not talking about just any lava lake — it's one of only three that exist in the whole world. 

Tucked away in the inner crater, nearly 3,700 meters above sea level, this pool of molten rock reaches temperatures between 900 and 1,130°C (1,652 to 2,066°F). The lake itself is always moving and changing, sometimes spanning 40 meters across, other times shrinking to just 10 meters. 

Mount Erebus is a key site for volcanologists, who study its ongoing activity, lava lake, and extreme environment.

NASA has even conducted research here to simulate conditions for planetary exploration, like on Mars.

As if that wasn't impressive enough, you'll spot massive crystals floating in the mix, some nearly as big as a baseball. It even erupts gold every single day!

History of Mount Erebus

The volcano's story — at least as far as Western science goes — began in 1841. That's when Sir James Clark Ross spotted it during his Antarctic expedition. 

He named it after one of his ships, the HMS Erebus, probably never imagining it would become such an important site for scientific research. The first people to reach its rim didn't come along until 1908, when some particularly brave members of Shackleton's expedition team made the climb.

Volcanic activity

Mount Erebus has been under continuous scientific observation since 1972, with researchers at the Mt. Erebus Volcano Observatory documenting its daily activities. 

Mount Erebus is known for its regular Strombolian eruptions, where glowing lava fragments arc through the air in spectacular fashion. While ash clouds or lava flows can also occur, these events are less common and are typically forecast well in advance by monitoring teams.

Can You Access Mount Erebus?

The Environmental Protocol of the Antarctic Treaty requires special permits for Antarctic access. These regulations serve to protect some of Earth's last truly pristine environments.

The permit process is complicated, but companies like Secret Atlas can facilitate small ship expeditions to Antarctica for those interested in experiencing this remote region but there are never any guarantees of seeing Mount Erebus. 

Before you start packing, check out our Antarctica travel guide and keep these points in mind:

• Even summer temperatures can plummet without warning

• Weather patterns can shift dramatically in minutes

• You'll need serious cold-weather gear — and lots of it

• Most visits happen through organised expeditions

• You should be in good physical shape

Experiencing Mount Erebus

Mount Erebus represents more than just another destination on a travel list, it stands as one of our planet's most extraordinary natural wonders. The remoteness and challenging conditions are precisely what make this Antarctic volcano so remarkable and preserved.

Observation opportunities are extremely limited, typically restricted to scientific expeditions. While specialised flights or icebreaker voyages theoretically provide the only viewing possibilities, these are exceptionally rare and primarily reserved for research purposes.

Secret Atlas can help adventurous travellers explore Antarctica's accessible regions, though direct Erebus access remains highly regulated.

If you’re ready to see where fire meets ice, get in touch with Secret Atlas to plan your small ship expedition to Antarctica. We'll help you navigate the complexities of Antarctic travel and make sure you prepare for an adventure that few people will ever experience. This isn't just a trip, it's a journey to one of Earth's most extraordinary places.
