Aurora Expeditions: adventure with a purpose

A pioneer of small-ship expedition cruising

When you sail with Aurora Expeditions, you're joining a community of curious travelers led by expert teams who care deeply about meaningful exploration. Founded in 1991 by Australian climbers Greg and Margaret Mortimer, Aurora pioneered the modern small-ship expedition model.

With decades of experience, Aurora has built a reputation for small groups, nimble itineraries and immersive learning journeys that explore both wild landscapes and cultural connections.

We've sailed with Aurora ourselves — including a full review of the Greg Mortimer — so this profile comes from firsthand experience.

The fleet: purpose-built for discovery

Aurora's ships — Greg Mortimer, Sylvia Earle and the new Douglas Mawson — are designed specifically for remote, challenging environments. Carrying just 132 passengers (154 on Douglas Mawson), they're small enough to navigate narrow channels and land in places large ships can't reach.

Ship details as published by Aurora Expeditions; confirm deployment per sailing.

Each vessel features the innovative Ulstein X-BOW, which allows for smoother crossing of swells, reduced vibration and better fuel efficiency. Dynamic stabilizers and Tier 3 engines further enhance onboard comfort while minimizing environmental impact.

The ships are rugged enough for polar seas, yet built with thoughtful communal spaces in mind: spacious observation decks, open-seating dining, a snug library, a wellness centre with gym and sauna, and even multiple Jacuzzis overlooking the ocean.

Where they go: from ice to equator

Aurora sails some of the planet's most remote and dramatic destinations — classic polar routes like Antarctica, South Georgia, Svalbard and the Northwest Passage, plus discovery expeditions in Greenland, Iceland, Norway, Oceania and Southeast Asia.

Douglas Mawson, launched in late 2025, returns the line to East Antarctica — including Cape Denison and Mawson's historic huts — plus journeys to New Zealand's Subantarctic Islands.

Itineraries are flexible and off the beaten path, prioritizing experience over schedule rigidity. Planning a polar voyage? Our guides to Antarctica, the Arctic and the Subantarctic Islands cover the regions in depth.

The vibe on board: intimate, curious and connected

With just around 130 guests per voyage, Aurora cultivates an atmosphere of camaraderie and shared discovery. The expedition-team-to-passenger ratio is one of the highest in the industry — there's always an expert available for lectures, questions or excursions.

The onboard vibe combines a relaxed, friendly atmosphere with structured learning. Expect engaging talks on climate science, wildlife biology, cultural heritage and exploration history — balanced with open-seating communal meals, library time and quiet deck-watching moments.

Staterooms all include ocean views, many with private balconies. Suites add perks like mini-bars, binoculars and spa credits.

Unique features and amenities

Standout features include the X-BOW ice-class hull with dynamic stabilizers for smoother voyages, rapid Zodiac boarding platforms with onboard mudrooms, wellness facilities, and citizen science programs that invite guests into real research.

Is Aurora right for you?

Aurora sails three purpose-built expedition ships: Greg Mortimer and Sylvia Earle, each carrying 132 guests, and Douglas Mawson, launched in late 2025, carrying 154. All feature the Ulstein X-BOW hull for smoother crossings, reduced vibration and better fuel efficiency.

Where does Aurora Expeditions sail?

Douglas Mawson returns the line to East Antarctica — including Cape Denison and Mawson's historic huts — and New Zealand's Subantarctic Islands.

What is the Ulstein X-BOW on Aurora's ships?

The Ulstein X-BOW is an innovative inverted bow design that pierces waves rather than riding over them. The result is smoother crossing of swells, reduced vibration and better fuel efficiency — a meaningful comfort advantage on passages like the Drake.

Guests are invited to participate in real scientific initiatives onboard — collecting data, attending workshops and joining expert-led lab sessions.
