Antarctica from New Zealand or South America: Which Gateway Is Right for You?

Two routes, two very different Antarcticas

Antarctica is vast — roughly the size of the United States and Mexico combined — and the two main tourist gateways lead to opposite ends of it. Ushuaia, at the southern tip of Argentina, is the jumping-off point for the Antarctic Peninsula, the jagged finger of land that reaches up toward South America. Christchurch in New Zealand is the gateway to the Ross Sea, deep on Antarctica’s Pacific side, roughly 3,800 km across the Southern Ocean.

These aren’t interchangeable destinations with different entry points. The Peninsula and the Ross Sea offer different landscapes, different wildlife, different historical associations, and wildly different trip lengths. Understanding that distinction is the first step to choosing the right voyage for you.

Departing from South America: the Antarctic Peninsula

Over 90% of all Antarctic tourists travel via Ushuaia — and the city itself is well worth building a few extra days around. Perched at the southern tip of Tierra del Fuego and surrounded by the Martial Range, Ushuaia punches well above its weight as a destination in its own right. The hiking is exceptional: Tierra del Fuego National Park offers trails through lenga beech forest to glacial lakes, and the ridge walks above town deliver sweeping views over the Beagle Channel. The waterfront is lined with excellent seafood restaurants serving locally caught king crab and centolla, and the main street is packed with souvenirs, outdoor gear shops, and the kind of “end of the world” curiosities you’d expect from the world’s southernmost city. Two or three nights here before embarkation is time well spent.

From Ushuaia, expedition ships cross the Drake Passage in roughly 48 hours and arrive at the Antarctic Peninsula. The entire round trip takes 10 to 14 days, making it workable within a standard holiday allowance. The Drake has a fearsome reputation, and it earns it — it’s the roughest stretch of ocean on the planet, where Atlantic and Pacific meet with no landmass to slow the swell. Around 30% of crossings are genuinely rough; the remaining 70% are manageable to comfortable. Modern expedition ships carry stabilisers, and good seasickness medication helps most people through it — see our full guide on whether you’ll get seasick in Antarctica for practical advice. For many travellers, the two days at sea become part of the adventure: lectures from naturalists and polar historians, wildlife-spotting from the deck, and the unmistakable feeling of leaving the world behind.

The Peninsula itself rewards you with dramatic fjords, towering icebergs, and more wildlife than most people are prepared for. Dozens of operators run voyages here through the austral summer season (November to March), giving you a wide range of ships, price points, and itinerary styles to choose from. For travellers flying in from New Zealand or Australia, the journey to Ushuaia — typically via Buenos Aires or Santiago — is a long one, but it’s a well-trodden route and flights are readily available. Note that some Peninsula operators also offer a fly-cruise option, flying over the Drake Passage to King George Island and joining the ship there — a useful alternative if you’re short on time or prefer to skip the crossing entirely.

Departing from New Zealand: the Ross Sea voyage

Christchurch is one of five official Antarctic gateway cities and serves as the logistics hub for New Zealand’s Scott Base and the US McMurdo Station. For expedition cruise passengers, it’s the starting point for one of the most ambitious voyages available to civilian travellers. The Ross Sea lies some 3,800 km from the South Island, and reaching it means five to seven days of sailing each way through open Southern Ocean.

Total voyage lengths run from 27 to 32 days, and in some cases longer. The season is tightly constrained: pack ice keeps the Ross Sea accessible only in January and February, so there are just two months per year in which departures can operate. This limits the number of voyages to a handful per season — a stark contrast to the Peninsula’s hundreds of departures.

Those sea days are not wasted time. The Southern Ocean is rich with birdlife — albatross, petrels, and prions wheel around the ship constantly — and experienced naturalists and historians make those days immersive and educational. But you should go in knowing that a Ross Sea voyage demands real commitment in terms of time and budget.

Wildlife: what you’ll encounter at each destination

Both destinations offer remarkable wildlife, but the species profiles are very different. On the Antarctic Peninsula, you’ll land among vast colonies of Gentoo, Chinstrap, and Adélie penguins. Humpback whales feed in the nutrient-rich waters — often coming remarkably close to Zodiac boats — and leopard seals lounge on ice floes. The birdlife is spectacular: skuas, giant petrels, and nesting albatross are regular sightings. Research stations (Argentina’s Base Brown, the UK’s Port Lockroy) add a human dimension to the landings.

The Ross Sea is where you come for Emperor penguins. With up to 240,000 Emperors in the region, it’s the part of Antarctica where most ships have a realistic chance of encountering the world’s largest penguin species. Adélie penguins breed here in enormous numbers — Cape Adare, at the northern entrance to the Ross Sea, hosts the largest Adélie rookery on Earth. The Ross Sea is also one of the few places in Antarctica where Weddell and Ross seals are regularly seen. Add to that the Ross Ice Shelf (the size of France), active volcano Mt Erebus, and the preserved historic huts of Scott and Shackleton at Cape Evans and Cape Royds, and the Ross Sea offers a depth of experience that is hard to match anywhere else on the continent.

Trip length and cost

This is where the two options diverge most sharply. Antarctic Peninsula cruises from Ushuaia start from around USD $6,000–$7,000 per person on a smaller expedition vessel, with most quality voyages falling in the $8,000–$15,000 range for 10 to 14 days. That’s a significant investment, but one that fits within a realistic holiday budget for many people.

Ross Sea voyages from New Zealand start from around USD $27,000 per person for a 27-day trip, with luxury options on vessels like the Scenic Eclipse running considerably higher. These are some of the most expensive expedition cruises available anywhere in the world, reflecting the distance, duration, and extremely limited capacity. Add the cost of flights to or from Christchurch (often not included) and the total investment is substantial.

The season matters too. Peninsula voyages run November through March — a five-month window with strong options throughout, though the peak months for wildlife differ from early season. The Ross Sea window is just January and February. If your available travel dates don’t fall in those two months, New Zealand simply isn’t a viable option for that year.

Operators and departure options

From Ushuaia, you’re spoilt for choice. Dozens of operators run Peninsula voyages across a wide range of ship sizes and styles — from small, nimble ice-strengthened vessels carrying 50–100 passengers (ideal for maximising landing time) to larger expedition ships with greater amenities. Operators include Hurtigruten, Ponant, Quark Expeditions, Oceanwide Expeditions, Aurora Expeditions, and many others. This competition keeps pricing relatively accessible and means departure dates are available throughout the season. If you want to compare ships side by side — ice class, passenger numbers, Zodiac capacity, cabin grades — our Expedition Ship Comparison Tool covers the main vessels operating in both regions and lets you line them up in one place.

The Ross Sea is a very different market. Only a handful of operators run voyages from New Zealand or Australia in any given season. Heritage Expeditions — New Zealand’s own family-owned expedition company, with over 35 years in the region — is the most established Ross Sea specialist, operating their 140-guest Heritage Adventurer. Scenic Eclipse offers ultra-luxury Ross Sea departures from Christchurch, and Aurora Expeditions and Oceanwide Expeditions also run occasional Ross Sea itineraries. With so few departures per season, voyages sell out well in advance — often 12 to 18 months ahead — and there is little scope to find last-minute deals.

Who should choose which?

If you’re coming to Antarctica for the first time, or working within a two-week window and a budget under $15,000 per person, the Peninsula is almost certainly where you should start. It’s efficient — two days across the Drake, six to ten days of actual Antarctic time, two days back. The wildlife is there in numbers that catch most people off guard, and the landscape does the rest. Most people who’ve done both routes started here, and most would tell you it was the right call.

The Ross Sea makes sense when the Peninsula isn’t enough — when you’ve already been, or when Emperor penguins and the preserved huts of Scott and Shackleton are the actual reason you want to go. It suits travellers who have a month free, a budget to match, and some genuine appetite for a deep commitment to one place. The people who come back from the Ross Sea talking about it in near-religious terms are usually people who knew exactly what they were signing up for. It’s not a trip that rewards half-measures.

For New Zealand-based travellers, there is a practical case for the Ross Sea simply because it departs from your own back yard — no long-haul flights to Argentina required. But be clear-eyed: that convenience comes at a very high price in dollars and time. If budget and time are constrained, flying to Ushuaia and doing a Peninsula voyage will almost always deliver more Antarctica per dollar.

Bottom line: New Zealand or South America?

For most first-time visitors — including those based in New Zealand — the Antarctic Peninsula via Ushuaia is the right call. It’s more accessible, more affordable, more flexible in timing, and the wildlife experience doesn’t need any qualifying. The Ross Sea from New Zealand is for people ready to go further: more time, more cost, a longer stretch of open ocean, and a part of Antarctica that very few people ever reach.

The choice ultimately comes down to your timeline, budget, and what you most want from the continent. If you’re unsure which fits your situation, that’s exactly the conversation worth having before you book — the last thing you want is to lock in the wrong voyage for a trip of this scale.
