Itinerary

Itinerary

An immersive expedition cruise to discover the highlights of the Antarctic Peninsula and cross the Antarctic Circle

Buenos Aires city in Argentina
Day 1

Arrive in Buenos Aires, Argentina

When you arrive in this cosmopolitan city, celebrated for its stunning architecture and deep European roots, you'll go to the hotel where our group will gather (this pre-expedition stay is conveniently included in the package).

Ushuaia harbour in Argentina
Day 2

Fly to Ushuaia and Embark

Following an early morning meal at the hotel, we'll head to the airport to catch our private charter flight to Ushuaia, Argentina. Once we land, you'll be shuttled from the airport to a spot right in the heart of downtown, where you'll have some free time to wander and soak up the charm of this picturesque port town before we all gather at the pier.

As we embark in the late afternoon and begin our voyage toward Antarctica, we'll cruise through the historic Beagle Channel. This channel, which owes its name to the ship that carried Charles Darwin on his epic journey, offers stunning views perfect for any photography enthusiast, featuring dramatic landscapes and an array of seabirds. Soon after, the channel leads us into the vast expanse of the Southern Ocean, setting the stage for our Antarctic adventure.

Days 3-4

Crossing the Drake Passage

During your days at sea, immerse yourself in engaging presentations delivered by your Expedition Team, covering topics like photography, wildlife, glaciology, and historical explorations. Between these informative sessions, enjoy moments on deck spotting wildlife or share stories and drinks with fellow travellers at the bar.

Days 5 - 7

South Shetland Islands and Antarctic Peninsula

Arriving on the 7th Continent often evokes a profound sense of wonder and respect. Antarctica's sheer pristine beauty is ineffable, a testament to its status as one of the last unspoiled places on Earth. You'll quickly understand the allure that has drawn explorers and adventurers to its icy shores for centuries. Antarctica reveals new surprises with each visit, guaranteeing that your journey will be a one-of-a-kind, deeply personal exploration.

 

Daily Zodiac outings will transport you from your ship into the heart of glaciated inlets, through narrow channels, and onto remote landing spots. Under the watchful guidance of your Expedition Team, you'll traverse the stark Antarctic terrain, pay visits to scientific stations, or mingle with the local inhabitants—chinstrap, Adélie, and gentoo penguins. Keep your eyes peeled for various seals, including Weddell, fur, crabeater, the elusive leopard seal, and whales that might include humpbacks, minkes, and possibly orcas during your Zodiac adventures. Each trip ashore or cruise promises new wildlife encounters that will captivate and demand your lens's attention.

In the tranquil silence of the Antarctic wilderness, the occasional sounds of nature, from penguins quarrelling over stones to the thunderous spectacle of glaciers calving, leave a lasting impression.

Your days will unfold in a tapestry of unique experiences meticulously curated by your Expedition Team to enrich and enlighten your understanding of this magnificent corner of the globe.

Days 8 - 9

Antarctic Circle

Making it past the Antarctic Circle is an unforgettable and notable milestone, as it's a journey not many get to make. If the weather and sea conditions are in our favour and we manage to navigate beyond the renowned 66°33' S line, we'll celebrate the bravery of the earliest adventurers who dared to explore these parts. It's a moment for you to toast, filled with pride, for arriving at a corner of the globe only a select few have ever witnessed. You're now in the heart of untouched Antarctica, where the midnight sun shines, Weddell seals roam, and you're likely to come across sea ice, the vital component of the Antarctic's rich marine life.

Days 10 - 11

Northbound Along the Peninsula

At this stage, you'll be as familiar with Adélie, chinstrap, and gentoo penguins as you are with distinguishing between leopard, crabeater, and Weddell seals. You'll find yourself using terms like 'bergy bits' and 'pancake ice' as if they've always been part of your lexicon, yet there's still so much more to discover. As we navigate northward, your days will be packed with Zodiac outings, and our Expedition Team will keep an eye out for any seabirds, seals, and whales you might not have encountered on our voyage south.

Polar Plunge

During each voyage, we carve out a special moment for the Polar Plunge, a thrilling dive into the icy waters, scheduled just once for those daring enough to leap. Our Expedition Leader and Captain are always on the lookout, assessing the weather and sea conditions to pick the perfect spot and moment for this exhilarating experience. Whether it's from the shore, off the gangway, or the edge of a Zodiac, participants, clad in tethered harnesses for safety, leap into the chilly embrace of the polar sea amid the cheers and encouragement of their fellow adventurers and the Expedition Team.

Safety is our top priority during the Polar Plunge. The onboard physician is always present to oversee the event, ensuring everyone's well-being.

Additional helicopter excursions are available for purchase once onboard for those seeking even more adventure. However, it's important to remember that all helicopter activities are subject to the whims of the weather and logistical considerations.

Alpine Heli-Trekking

Once you touch down, whether walking, hiking, or snowshoeing, the adventure continues with magnificent vistas of untouched ridges, icy landscapes, and snow-crowned peaks. This extraordinary heli-trekking experience promises to immerse you in the awe-inspiring beauty of Antarctica, leaving you with memories that will last a lifetime.

Experience the beauty of the polar regions from the intimacy of a sea kayak. The onboard Sea Kayak Program gathers adventurers with a shared passion to explore the stunning landscapes of fjords, glacial fronts, or intricate sea ice formations together.

This program welcomes both novices and experienced kayakers to discover the polar regions from a distinctive vantage point. Depending on weather and operational conditions, the goal is to get kayaking as frequently as possible. Sea kayaking adventures typically begin with a Zodiac boat transferring participants from the ship to an optimal launch site. After exploring the waters, kayakers are brought back to the ship via Zodiac. 

For safety, a Zodiac operated by a dedicated driver remains close at hand to provide help if needed. These kayak trips usually last from one and a half to three hours, blending adventure with unparalleled natural beauty.
