Antarctic Peninsula: A Rare Exploration of the Weddell Sea
Antarctic Peninsula
Spend more time in the remote, ice-laden Weddell Sea—home to massive Adélie penguin colonies and colossal tabular icebergs—than you ever imagined possible. While many Antarctic itineraries attempt to include the Weddell, they typically spend just a day here, two at most. This Exploration devotes three to four days in the farthest reaches of the Weddell Sea and Antarctic Sound. In fact, our arrival in Antarctica coincides with the Winter Solstice. This route is designed with maximum flexibility to adapt to shifting conditions and reach rarely visited sites
Highlights
- Join a rare, in-depth journey into the remote Weddell Sea and Antarctic Sound
- Photograph massive flat-topped tabular icebergs
- Visit archeological sites amid volcanic and scenic landscape
- See tens of thousands of Adélie penguins
- Spot a variety of whales: Humpbacks, minkes, fin, and, possibly, killer whales.
- Explore off-ship by Zodiac and kayak
Ready for a little adventure beyond your ship? This voyage offers a variety of recreational activities to enhance your polar experience.
ZODIAC CRUISING
Zodiacs are the workhorses of polar expeditions, taking you to places the ships can’t access, allowing you to reach remote shorelines, explore shallow inlets and search for unique wildlife. Expedition staff make stepping in and out of them safe and comfortable, and your Zodiac drivers will provide active interpretation, making the landscape come even more alive.
HIKING
Led by experienced staff, exploring on foot is one of the best ways to appreciate the polar landscapes. Our guides are able to accommodate a range of skill levels. Hiking in offers a variety of terrain, both off-trail and on established paths.
PRESENTATIONS
Enjoy daily chats with and presentations by our world-class onboard polar experts—expedition guides, specialists, photography guides and other special guests who will introduce you to the fascinating history, biology, ornithology, glaciology and geology of the region, and much, much more.
POLAR PLUNGE
This rite of passage, scheduled only once per expedition, gives you the chance to jump safely into the bracing polar waters under the watchful eye of our staff—and just about every single camera on board.
PHOTOGRAPHY
Documenting your voyage so you can take the memories home is a rewarding experience. Our photography guides will help you hone your skills to capture the beauty of the polar regions.
SCIENCE AND DISCOVERY
THE ONBOARD Science & Discovery program offers guests the unique opportunity to engage directly with scientists and researchers and participate in citizen science activities with the expedition team to collect and record data. Activities include conducting seabird surveys on deck, documenting whale sightings, and participating in interactive water sampling activities to measure environmental conditions.

The ship was perfect size
Food and service were excellent
No one mentioned there were 2 hot tubs so we weren’t prepared and didn’t tell us there were one day kayaking options available. Luckily we were able to sign up
Stewart's Take
See more of Antarctica than the regular Peninsula itineraries
Overview
Spend more time in the remote, ice-laden Weddell Sea—home to massive Adélie penguin colonies and colossal tabular icebergs—than you ever imagined possible. While many Antarctic itineraries attempt to include the Weddell, they typically spend just a day here, two at most. This Exploration devotes three to four days in the farthest reaches of the Weddell Sea and Antarctic Sound. In fact, our arrival in Antarctica coincides with the Winter Solstice. This route is designed with maximum flexibility to adapt to shifting conditions and reach rarely visited sitesItinerary
DAY 1 Arrive in Ushuaia, Argentina You may arrive in Ushuaia at any time on Day 1. Many guests choose to arrive a day or two before embarkation day to explore this quaint port city at the bottom of South America, and the surrounding region. Based on the arrival information you send in advance, we will arrange for a transfer from the airport to your hotel. DAY 2 Embarkation Embarkation will occur in the late afternoon, after which your vessel will sail down the historic Beagle Channel, transecting the Tierra del Fuego archipelago in the extreme south of South America. Expect an air of anticipation as you depart—the next time you see land, you’ll be at the world’s most southern continent. DAY 3 & 4 At Sea: Crossing the Drake Passage You have many options of activities during the 800-km (500 mile) Drake crossing. As you gain your sea legs, our Expedition Team will begin their series of presentations to help prepare you for your upcoming Zodiac and land excursions. You officially enter Antarctica when your ship crosses the Antarctic Convergence, a boundary that f luctuates around 60° south. This is also a great opportunity to meet your fellow travelers—many of whom will become friends by the voyage end. DAY 5 TO 9 Antarctic Sound and the Weddell Sea One word best describes the Weddell Sea and Antarctic Sound: immense. That applies equally to the ice formations, penguin colonies, and vast stretches of sea. In Antarctic Sound and the Weddell Sea, we will encounter massive tabular icebergs. These bergs don’t calve from tidewater glaciers but from ice shelves— and many will dwarf Ocean Explorer. Some in the Weddell Sea reach the size of a football field or larger. Their smooth, tabletop-flat surfaces reflect the ocean beneath: flat seas yield flat ice. Ice shelves stretch from land into the sea. In the northwest corner of the Weddell Sea, penguin colonies can number in the tens of thousands. Abundance of Penguins For travellers seeking Adélie penguins, Antarctic Sound and the Weddell Sea offer prime viewing of this iconic species—the most southerly breeding penguin, and possibly bird, on Earth (though snow petrels, prevalent here, are also a contender for that crown). Gentoo penguins are found here too, and you’ll have chances to spot chinstraps. The legendary Snow Hill Emperor colony lies in this region; while we won’t reach it, we may encounter individual members on the ice. In the realm of ice The Weddell Sea is less visited than the Gerlache Strait, not for lack of beauty, but due to its ever-shifting ice. On this voyage, we’ve added an extra day in this area—time enough for a true adventure into this endless wilderness, and to ensure we can fully embrace the dance with the ice. In the Weddell Sea, penguins are our priority—but ice will guide our course. Alongside towering tabular icebergs, we’ll likely encounter vast stretches of sea ice, more than on the Peninsula’s west side. Your Expedition Team and bridge officers will track charts and forecasts, seeking openings to navigate toward the region’s highlights, and intentionally visiting the ice edge to maximize our time in this remarkable environment. A region of discovery Our route will be shaped by sea ice and weather, but every destination— whichever we visit first or last—will be exceptional, evoking words like profound, humbling, and surreal. We’ll make every effort to visit large Adélie penguin colonies—at Brown Bluff, Paulet Island, or Tay Head—ranging from 20,000 to several hundred thousand penguins, including gentoo. Photos and documentaries can’t match the experience of standing before tens of thousands of penguins. The sounds alone—partners calling, chicks crying for parents, wind and waves against the shore, and the distant crack of calving glaciers—create an acoustic landscape of pure wildness. Add the sight of a penguin-covered landscape, and you have an encounter that’s impossible to replicate. The currents of Antarctic and Active sounds are mesmerizing. Zodiac excursions While you’re in a Zodiac, you may observe ice—large and small—flowing through narrow straits at several kilometers per hour, a raw display of the power of water. From shore, you may glimpse or sense the ice’s movement. Your Zodiac may pass through open water, while your return ride could weave among drifting floes, crackling brash, and scattered bergy bits. The Weddell Sea is known for superb birdwatching—especially cape, snow, and southern giant petrels—and the chance to spot Weddell, crabeater, or leopard seals onshore or catching rides on the drifting ice. Sightings may occur near Adélie colonies or at sites like Kinnes Cove and Active Sound. Whales When ice opens in the Weddell Sea’s northwest, whales follow—lured by the feeding opportunities. Humpbacks and minkes are most common, with occasional killer whales. Conditions may also allow us to explore areas frequented by fin whales, and possibly southern rights. Redolent with polar history For historians, the Weddell Sea brims with stories—from Shackleton’s legendary Endurance survival and Nordenskjöld’s gallows-humored ordeal on Antarctic to far older histories told by the 60-million-year-old fossils on The Naze, Vega Island, and Cockburn Island. Fossils are discovered here partly because large areas remain relatively snow-free. Volcanic activity has painted these sites—as well as Brown Bluff on the Peninsula’s mainland—in rich reds, burnt oranges, and chocolate browns. In a landscape dominated by white, gray, and blue, these colors add a vivid layer to a region steeped in both human and ancient geological history. This itinerary offers the best of a polar expedition—soak in the vastness of the Weddell Sea and Antarctic Sound from your ship, then get up close to stunning geological formations by Zodiac or kayak. DAY 10 & 11 At Sea: Homeward-bound across the Drake Passage The journey back across the 800-km (500 mile) Drake Passage provides final opportunities to enjoy the crisp Antarctic air, spend time on the outer deck watching for seabirds and whales, or attending one of our team’s expert-led polar presentations. DAY 12 Disembark in Ushuaia Your ship is scheduled to arrive in Ushuaia between 7 a.m. and 8 a.m. Once the ship has docked, you will bid farewell to your Expedition Team and shipmates before completing your disembarkation. You are then free to take advantage of the included transfer to the airport or, depending on the time of your flight, explore the town on your own and take a taxi to the airport laterSea Kayaking

Selected departures may include an option for Sea Kayaking – contact us for availability! Sea kayaking on a polar expedition brings you face-to-face with the polar wilderness from a unique, water-level vantage. Glide silently among icebergs and beside glaciers, drift past curious birds or seals, and explore remote fjords and coastline not accessible by ships. Kayaking becomes a deeply immersive, sensory experience—crisp air, icy water, wildlife calls and the hush of untouched nature. Guided by expert polar staff, you paddle safely in small groups, often with Zodiac support close by. Whether you choose a single paddle outing or a full kayak program, this adventure gives you an intimate connection with polar landscapes few ever experience. >>Read More Details on this information page!
