Antarctica Peninsula via Ushuaia: A Practical Guide to 66° Expeditions' 10-Night Voyage on SEAVENTURE

What This Route Is and Who Operates It

In our inventory, this South America expedition route is served by a single cruise line — 66° Expeditions — operating one confirmed departure in November from Ushuaia, Argentina. The vessel assigned to this itinerary is SEAVENTURE, an expedition ship with a guest capacity of 150 passengers. The itinerary's headline destination is the Antarctica Peninsula, reached by crossing the Drake Passage from the southernmost city in the world. With only 1 departure currently listed in our inventory, travellers considering this route should treat availability as genuinely limited and plan their booking timeline accordingly. The sole departure month in our inventory is November, which places this voyage at the opening of the austral summer season — a period when sea ice is retreating and wildlife activity on the Peninsula is intensifying.

Itinerary Length and What Ten Nights Actually Covers

Every departure in our inventory runs for exactly 10 nights — the most common itinerary length across this line's offerings. For travellers weighing duration against destination coverage, 10 nights is a meaningful commitment: it typically allows for two full Drake crossings (southbound and northbound) plus several days of active expedition time on or near the Antarctica Peninsula itself. Travellers considering a shorter polar trip should understand that the Drake Passage alone accounts for roughly two days of sailing each way, meaning the net time spent in Antarctic waters is concentrated into the middle portion of the voyage. A 10-night structure, as offered here, provides more landing opportunities than shorter polar itineraries, though it does not extend as far south as some longer voyages might. Travellers who want to reach deeper into the Peninsula or visit sub-Antarctic islands should compare this itinerary length against longer options before committing.

Embarkation Port: Ushuaia

The sole embarkation port in our inventory for this route is Ushuaia, the southernmost city in Argentina and the conventional gateway for Antarctica Peninsula expeditions. Travellers should plan to arrive in Ushuaia at least one full day before the November fifth departure to account for flight delays, luggage logistics, and pre-boarding briefings that expedition operators typically schedule the evening before sailing. Ushuaia has a well-established infrastructure for polar departures, with gear rental shops, expedition outfitters, and a compact city centre walkable from the cruise terminal. Travellers considering this route should budget time to explore the city and the nearby Tierra del Fuego national park before or after the voyage — both add context to the sub-Antarctic landscape that frames the journey south.

The Ship: SEAVENTURE and What a Capacity of 150 Means for Landings

SEAVENTURE, operated by 66° Expeditions, carries up to 150 guests in our inventory listing. For travellers comparing expedition vessels, guest capacity is one of the most operationally significant variables on an Antarctica itinerary. Antarctic Treaty regulations cap the number of passengers ashore at any one landing site at one hundred, meaning a ship carrying 150 guests must rotate landings in groups — some passengers will be ashore while others remain on board or participate in Zodiac cruising. This rotation system is standard practice on mid-size expedition ships and is not a disadvantage per se, but travellers who prioritise maximum time on the ice at every site should weigh this against smaller-capacity vessels that can land all guests simultaneously. Conversely, a ship of 150 guests typically offers more onboard amenities, lecture space, and social atmosphere than ultra-small polar vessels, which suits travellers who value the shipboard experience alongside the landings.

Pricing, What Is Included, and the Single Supplement Picture

In our inventory, 66° Expeditions prices this 10-night voyage from $10,000 per person. Prices and availability are subject to change; final price confirmed at booking. Expedition Antarctica voyages at this price tier are typically structured as highly inclusive packages. Travellers considering the all-in cost should factor in that expedition fares at this level commonly cover accommodation, all meals, Zodiac landings, naturalist-guided shore excursions, and expedition gear such as rubber boots and waterproof outerwear — though the precise inclusions must be confirmed directly with 66° Expeditions at the time of booking, as package scope varies by operator and departure. On the single supplement question: in our inventory, there are zero departures on this route that carry at least one cabin available at no single supplement. Solo travellers should therefore budget for a single supplement on top of the from-$10,000 base fare and confirm the supplement rate with the operator before booking. Prices and availability are subject to change; final price confirmed at booking.

Physical Demands and Who This Voyage Suits

Travellers considering an Antarctica Peninsula expedition should approach the physical requirements honestly. Zodiac boarding and disembarkation — the standard method for reaching shore — requires stepping between a moving inflatable craft and a rocky or icy landing site, often in swell. This demands reasonable balance, lower-body strength, and the ability to follow crew instructions quickly. Travellers with significant mobility limitations should discuss accessibility in detail with 66° Expeditions before booking. The Drake Passage crossing, which bookends this 10-night itinerary, is one of the most dynamic stretches of open ocean in the world. Conditions range from calm to very rough, and even experienced sailors can find it challenging. Travellers prone to motion sickness should consult a physician about preventive medication well in advance. Beyond sea-legs, the expedition itself — hiking on uneven terrain, standing for extended periods during wildlife observations, and managing layered cold-weather clothing — calls for a baseline of general fitness rather than athletic ability. Most healthy adults who prepare appropriately are well-suited to this style of travel.

Timing: Why November Matters for the Antarctica Peninsula

The single departure in our inventory departs in November, placing it at the start of the austral summer. For the Antarctica Peninsula specifically, November is associated with the arrival of breeding seabirds and the early stages of penguin nesting activity, as colonies establish territories and eggs are laid. Sea ice is typically retreating at this time of year, opening up landing sites that may have been inaccessible earlier in the season. Travellers who are flexible on timing and weighing November against later summer months should consider the trade-offs: earlier departures tend to offer more dramatic icescape scenery and the spectacle of nesting behaviour, while later departures — December through February — often coincide with penguin chick hatching and whale feeding activity closer to the Peninsula. Since our inventory currently lists only 1 departure, travellers with a strong preference for a specific wildlife window should confirm the precise itinerary dates and expected conditions with 66° Expeditions directly. Prices and availability are subject to change; final price confirmed at booking.
