Crossing the Antarctic Circle
Celebrate the opportunity to cross the Antarctic Circle on this 14-day voyage aboard a selection of top-of-the-line expedition ships, and enjoy in-depth exploration of the Antarctic Peninsula, penguins and icebergs.
Become one of the few who can claim to have crossed the Antarctic Circle. The 14-day Crossing the Antarctic Circle voyage not only includes in-depth exploration of the Antarctic Peninsula, but it also offers the opportunity to venture as far south as 66°33´S.
Enter the land of the midnight sun to a world without borders as you sail across an endless stretch of sea dotted with ice. Search for wildlife that claims solitude as home. Whether it’s humpback whales alongside the ship, a leopard seal diving beneath your Zodiac, penguins sliding off an iceberg into crystal waters or a giant petrel soaring above cracking sea ice, you’ll experience a sensory overload in Antarctica like you’ve never felt before.
Begin with a pre-cruise overnight in Buenos Aires, Argentina, then fly on to Ushuaia and embark. The alternative Antarctica by Helicopter: Crossing the Circle itinerary follows a similar route but adds an included helicopter landing amidst Antarctica’s vast coastal mountains, plus at least two helicopter flightseeing excursions.
On board, lectures and specialists cover Antarctica’s geology, history and wildlife, while an expert expedition team helps to embrace Antarctica’s vast beauty. A selection of small ships attempt to cross the circle: the 168-guest World Voyager or the 199-guest Ultramarine. Each Crossing the Antarctic Circle departure includes up-close exploration on guided hikes, shore walks and small craft excursions. Optional activities (additional cost) may include kayaking, one-time paddling excursions, camping and stand-up paddleboarding. Ultramarine’s helicopter activities make her departures an excellent option among our luxury Antarctica cruises.
Come to the land where the sun never sets, where explorers celebrate when conditions allow their achievement of what few others can claim: the Crossing of the famed Antarctic Circle.

Antarctic Peninsula: Crossing the Circle Itinerary
The 14-day Antarctic Peninsula: Crossing the Circle cruise begins and ends in Buenos Aires, Argentina, with charter flights to and from Ushuaia. It not only includes in-depth exploration of the Antarctic Peninsula, but it also offers the opportunity to venture as far south as 66°33´S.
Upon arriving in this cosmopolitan city, known for its architecture and rich European heritage, you will independently transfer to your group hotel (pre-expedition hotel night included with your Charter Flight & Hotel Package).
After an early breakfast at the hotel, transfer with the group to the airport and board a private charter flight to Ushuaia, Argentina. Upon arrival, be transferred from the airport to a central downtown location to have some time on your own to explore this quaint port town before making your way to the pier.
As the ship sets sail in the late afternoon, begin the Antarctic journey, passing through the Beagle Channel. Named after the famed ship on which Charles Darwin voyaged, the channel presents great photo opportunities of landscapes and seabirds. Eventually the channel opens up to the Southern Ocean, and on to Antarctica.
These days at sea are filled with presentations and lectures led by the expedition team, who will prepare you for the wildlife ahead. In between presentations, spend time chatting with shipmates over a drink at the bar, or enjoy the fresh air and views on the outer decks.
The most common reaction upon reaching the White Continent is a sense of reverence and awe. The experience is beyond words, since few places are as untouched, unique and enduring as Antarctica. Begin to appreciate why this region has long captivated the attention of explorers and travelers alike. Every visit to Antarctica bears witness to something new or unexpected, which means that this expedition will be unlike any other—creating a unique, personal experience.
Each day, take Zodiac excursions from the ship to explore local bays, channels and landing sites. Visit penguin rookeries, scout for humpback and minke whales, and search for a number of southern seal species, including the cunning leopard seal. The expedition team will oversee each landing, whether exploring the Antarctic terrain, visiting a research station or consorting with penguin colonies. Chinstrap, Adélie and gentoo penguins are found here. Each day and each landing will present a new collection of creatures to delight and keep the camera busy.
Your days will be busy spotting wildlife and being mesmerized by the astounding beauty of Antarctica. Listening to the crackling and crumbling of icebergs and glaciers and watching penguins waddling on the beach will become your daily entertainment.
Crossing the Antarctic Circle is an impressive achievement, as most expeditions to the Antarctic Peninsula do not reach this far south, which is officially noted at 66°33´S. If conditions allow the crossing of this famed line, celebrate in style alongside shipmates with a toast. Take pride in knowing you’ve made it to a part of the world visited by very few people. This is raw Antarctica, home of the midnight sun, Weddell seals, and the best chances of encountering sea ice – the foundation of the Antarctic marine ecosystem.
By now, your knowledge of Adélie, chinstrap and gentoo penguins will be matched by your ability to differentiate between a leopard, fur or Weddell seal. Terms like bergy bits and pancake ice will seem normal, yet there are still many tales to be told. As the ship heads north, Zodiac excursions will fill the days, and the expedition team will continue offering presentations and looking out for species of penguins, seals and whales.
As the ship recrosses the Drake Passage, Antarctica fades away, leaving a collection of memories to last a lifetime. Excited conversations with newfound friends will make the crossing fly by, regardless of weather and sea conditions. The expedition team will round up its series of lectures as well, perhaps with a slideshow of the great landing sites and wildlife witnessed over the course of the voyage. Enjoy the time to reflect on everything experienced so far.
Arrive in Ushuaia in the morning and disembark after breakfast, before transferring to the airport for the return group charter flight to Buenos Aires.

She is equipped with the industry-leading Micro Auto Gasification System, which converts waste into recycled onboard energy. And her two hybrid-electric Rolls Royce engines keep fuel consumption down, while also offering a smooth ride. Additionally, two elevators access all decks, helping ease movement around this spacious 8-deck ship.
Onboard Facilities
Every aspect of an incredible expedition cruise is accounted for on this ship. Like World Explorer, her 6 passenger decks offer opportunities to get active, relax with fellow guests, take in educational lectures and breathe in the invigorating polar air. Add a medical clinic, plenty of public restrooms, and panoramic views throughout the ship, and it's clear the World voyager is ideally suited for polar expedition cruising.
Lecture Theater & Observation Decks
The lecture theater on Deck 4 offers seating for the entire passenger complement, with regular presentations and/or films on offer. Moving up the ship, commanding views of the surrounding polar wilds can be accessed everywhere, with a few standout locations.
The bow of Deck 5 reveals 180-degree views from its exterior deck. Deck 6 has an open bridge with special wings that jut out beyond the walls of the ship.

Dining & Bars
Deck 4 plays host to a variety of social areas aboard the World Voyager cruise ship. Anchoring every day is the onboard restaurant, with an elegant feel but casual approach, including unassigned seating and enough room for all guests to dine at the same time. Meals are international in flavor, with classic dishes on offer daily, alongside a rotating list of options. While al fresco seating is available at the aft of the dining room, it is typically reserved for warmer climates. For drinks and snacks with a view, the Deck 7 Observation Lounge is a great choice.
Pool, Jacuzzis, Sauna, Steam Room & Gym
The World Voyager cruise ship sets herself apart with her variety of wellness amenities, all accessible to every passenger (not just those who opt for a treatment). The World Voyager offers a spa that outsizes that of her predecessor ship, World Explorer.
Relax knowing you won't miss any wildlife through the floor-to-ceiling windows of the spacious sauna and its adjoining relaxation lounge with steam room.

Activities & Expeditions
The World Voyager is just as adventurous as she is refined. She carries a fleet of Zodiacs to get all guests out exploring at the same time. And her gear racks are stocked with sleeping bags, bivouac sacks and mats for camping; inflatable stand-up paddleboards and "kayaks," dry suits, neoprene gloves/booties and adjustable paddles for shorter outings; and fiberglass sea kayaks for longer, repeated excursions.
Crew, Guides & Expedition Leaders
With 125 staff and crew, and only 168 guests, the service is first-class both on and off this ship. As a newer ship in the Quark fleet (joining after World Explorer), with upscale spaces, World Voyager attracts some of its operator's top guides, ensuring your cruise will be memorable. Expect a cerebral and passionate group of guides, who are also safety-minded, approachable and light-hearted; and a dedicated crew who will quickly learn your preferences.

Or consult this page further for a detailed description of the Ultramarine, including ship specs, deck plan, cabin images, photo gallery and current links to all the trips she sails. We can help compare the Ultramarine with other Antarctica ships and ice-class expedition ships offering Arctic cruises, Iceland cruises, Greenland cruises, Patagonia cruises and Antarctica cruises.
Design, Sustainability & Accessibility
Designed in collaboration with active expedition leaders, this ship offers innovative features to increase guests’ on- and off-ship experiences.
Helicopters, Zodiacs & Activity Gear
This polar ship has two twin-engine H145 helicopters launched from two simultaneously operable helidecks for heli-skiing, heli-hiking, flightseeing and exploration of air-only accessible destinations. These helicopters are the most fuel-efficient in their class, celebrated for their small footprint and reduced noise pollution. They enable polar travelers to explore deeper in the remote areas in which Ultramarine sails (except for South Georgia in Antarctica and Spitsbergen in the Arctic). Helicopter operations require roughly 20 expedition team members and pilots to run successfully, and operate in tandem with paddling and Zodiac activities.
Days are packed with multiple landings by Zodiac, enabled by the ship's rapid Zodiac deployment tools. Ultramarine's internal Zodiac hanger provides safe and quick deployment of 20 Zodiacs with four embarkation points easily accessible from two ready rooms, enabling all passengers to offload the ship at the same time. When possible, the Expedition team uses a rear dock that lowers to water level for efficient Zodiac loading.
Ultramarine additionally offers the largest selection of classic adventure options, including sea kayaking (hard plastic boat), paddling (inflatable kayak), camping, mountaineering and stand-up paddleboarding (inflatable board). All activities are led by highly trained guides and expedition leaders, and all paddling activities include a drysuit and gloves.
Safety Features
The groundbreaking safety features of Ultramarine include 13 fully redundant critical systems, twin propellers powered by four diesel-electric engines in two separate engine rooms for consistent backup and engine reliability, stabilizers, as well as a fully operational emergency bridge. This expedition vessel also has an ice strengthened hull and dynamic positioning capabilities. The dynamic positioning technology also means no need to anchor, avoiding damage to sensitive seabed ecosystems.
Responsible Travel Features
Ultramarine's sophisticated and environmentally friendly waste handling systems allow for treatment of waste to be managed safely in far-off distances. Her numerous innovations are designed to minimize her environmental footprint to an extent previously unseen for a vessel of comparable size, including a sophisticated water treatment system, state-of-the-art waste handling (Micro Auto Gasification System incinerates waste that then creates stored energy for use on board), a leading-edge heat recovery system that recycles excess energy back into the ship, LED lighting, and the use of entirely recyclable materials to construct it.
Other Facilities
Digital wristbands enable both keyless cabin entry and computer-logged tracking of entry and exit from the ship. An elevator services all decks. Finally, an onboard, English-speaking doctor is available 24 hours a day. The ship's physician manages a medical clinic stocked with a supply of common prescription medicines and basic first aid equipment.
Crew, Guides & Expedition Leaders
The 140 crew members of Ultramarine work together to create a seamless guest experience. This premiere ship within the Quark Expeditions fleet attracts top guides, many with over 10 years of experience with the company.
