January 21st – 30th, 2023

Following up on our very successful and well-received voyage to Antarctica in 2022, Lewis & Clark is thrilled to invite our community back on the same ship in 2023 during the height of the wildlife season.

This expedition to the Seventh Continent will be guided by Clinical Professor of Law Erica Lyman and has been tailored for an intrepid group of Lewis & Clark alumni, family, and friends. Our route will navigate the famed Drake Passage, visiting unique locations across the South Shetland Islands and Antarctica Peninsula that have amazed and inspired scientists, explorers, and sightseers alike for centuries.

Alongside Professor Lyman, we will be joined by highly experienced Antarctica experts and expedition leaders who will present lectures and hands-on workshops ranging from marine wildlife, ecology, climate change, photography, and the history of the various locations we visit.

Travel in style aboard one of the newest and most luxurious vessels in the polar regions—The World Navigator—which utilizes leading technological innovation to get you closer than ever to snowy peaks, colossal blue glaciers, and roaming icebergs. Enjoy gourmet meals, open bar throughout, and as many 7th-continent landings as possible on this all inclusive voyage. Our ship is also one of the most environmentally friendly at sea, using a clean-burning hybrid electric-hydro propulsion and anchor less positioning systems. All cabins feature luxurious amenities, complimentary 24-hour room service, and enlarged picture windows with pristine ocean views. In addition, exclusively for our ship, we have chartered a private plane in Argentina from Buenos Aires to Ushuaia, which is included in cost of the program.

Don’t miss this once-in-a-lifetime expedition to one of the most majestic landscapes on the planet.

Built for the explorer at heart, World Navigator is made for those who believe in experiencing their destinations up close without leaving a major footprint. The vessel set sail in 2021 for its inaugural season with state-of-the-art technology that allows for remarkable expeditions with responsible citizenship in mind.

A hybrid power management and propulsion system from Rolls-Royce maximizes World Navigator’s fuel efficiency. It consumes as low as one-fifth the fuel used by cruise ships with conventional systems. Two onboard hydro jets propel the vessel at a near-silent cruising speed of five knots. This helps minimize underwater noise so that you can get closer to marine wildlife without disturbing it. A sophisticated, GPS-based Dynamic Position System controls propellers, tunnel thrusters, and hydro jets to maintain the ship’s position avoiding the need for anchors, which harm ocean floor life.

Designed for best in class polar small ship cruising, World Navigator features two decks of luxurious accommodations, totaling just under 100 staterooms, less than 198 total guests, and provides the best way to enjoy Antarctica while protecting it for future travelers. As the expedition-style ship quietly navigates the remote and rugged locations, you will wonder why anyone would roam any other way.

DAY 0 - Travel to Buenos Aires, Argentina

Begin your journey to Buenos Aires, Argentina. 

DAY 1 - Buenos Aires to Ushuaia, Argentina

The morning of January 21, board our charter flight in Buenos Aires and fly to the southernmost city in the world, Ushuaia. The snow-capped Martial Mountains behind a sprawling city of colorful buildings create the backdrop of the southernmost city in the world: Ushuaia, Argentina. A mix of historic buildings and rugged nature make this city a welcoming stop for travelers venturing beyond to the Seventh Continent.

Upon arrival, board our ship, the World Navigator, and settle in for our voyage across the Drake Passage.

DAY 2 & 3 - Crossing the Drake

Voyage beyond the Beagle Channel and navigate the famed Drake Passage. Petrels and albatrosses that glide across the skies guide the way on this waterway where cold southern ocean meets warm northern sea water. While the waterway is famous for its challenging navigation, you may still get another side of the “Drake Lake”, as on some occasions, the channel is calm and flat. As you emerge from the Drake Passage, the mammoth, icy peaks of the South Shetland Islands loom ahead, greeting you on your victorious landing which is likely to happen before sunset on Day 3. 

During the crossing, enjoy a lecture by Professor Lyman on the wildlife we can expect to see in the days ahead, as well as expert talks by the seasoned guides on the ship.

DAY 4 - South Shetland Islands, Antarctica

The South Shetland Islands are silent and serene. Natural wonders like the black and white effect of Deception Island and the peaks of massive glaciers sitting atop the water’s surface inspire awe and admiration – even from the most veteran explorers. The stillness of the Shetland Islands evokes a sense of wilderness left to be discovered.

Along the rugged cliffs of Brown Bluff, the exposed portion of a glacial volcano, you can hike to a backdrop of expanses of ice and ocean. 

Deception Island, the caldera of an active volcano, creates a black-and-white photo effect with black sands mixed with white snow at Neptune’s Bellows. A dip in the steaming hot springs of a black sand beach feels like an unreal experience amid the snow-capped mountains in the background.

DAY 5 - 7 - Exploration on the Antarctic Continent

Enjoy three more days of exploration on the Seventh Continent, with an estimated two landings per day, guided by weather conditions. From the remarkable blue coloring of glaciers to leopard seals napping on ice floes, the Antarctic Peninsula contains a multitude of wonders to behold. Cormorants soaring high above and orcas breaching the waters below surround you with a magnificent array of wildlife that calls to your inner explorer. 

Visit the permanent ice cap at Cuverville which houses Port Lockroy, a flagship historic site for the main base building of Bransfield House. It’s also home to the famed Penguin Post Office, the southernmost post office in the world where you can make an unforgettable memory among the Gentoo penguins. At Neko Harbor, watch for humpback whales as their flukes come above the water and splash back down. Paradise Bay offers a glimpse into scientific research at Argentina’s Almirante Brown Antarctic Base or Chile’s González Videla Antarctic Base. Cruise in zodiacs along icebergs with your expedition guides, and enjoy daily optional activities including kayaking, paddleboarding, and of course, a polar plunge.

NOTE: Captain’s Choice ports of call add to the sense of adventure and an element of surprise. Your ship’s master will navigate the changing weather conditions as needed to take you to the best areas for wildlife viewing. Captain’s Choice ports include: Deception Island, Paulet Island, Brown Bluff, Neko Harbor, Paradise Bay, Cuverville Island and Goudier Island.

DAY 8 - Drake Passage Navigation

Recross the Drake Passage on the journey back to South America. The meeting of warm and cold waters creates an environment that attracts marvelous wildlife and the chance to witness humpback whales and hourglass dolphins that accompany the voyage back home. The soundtrack of the journey through the Drake Passage includes the cry of petrels, skuas, and gulls. We will also enjoy another series of lectures and presentations on all the wildlife we have seen throughout the journey, as well as discuss the conservation on this remarkable part of the planet and the stewardship of its land and seas in the years to come.

DAY 9 - Navigating Cape Horn, Chile

Behold the lush, yet imposing cliff, as you pass Cape Horn, the southerly head of Tierra del Fuego. 

Enjoy final lectures by Professor Lyman today and a farewell celebration on the World Navigator. 

DAY 10 - Ushuaia, Argentina

Arrive safely back at port in the morning at the “End of the World,” Ushuaia Argentina. Today we will have the chance to further explore this town and its wild natural surroundings before boarding our plane this afternoon for our flight back to Buenos Aires.

MEET YOUR Lewis & Clark Expedition Leader
