Antarctica’s Crowded Horizon

The headline Antarctic number went down last season. The number that matters for advisors went up. According to the International Association of Antarctica Tour Operators (IAATO), 113,518 people visited Antarctica in 2025–26, a 4.2 percent drop on the previous season. Over the same period, passengers who actually went ashore rose about 6 percent, to 85,195. Fewer ships and voyages carried more people onto the ice, and those people landed at a small number of sites. For clients who want to set foot on the continent, the scarce product is a good landing, and it goes to whoever books first.

The 2025–26 season in numbers

IAATO’s report to this year’s Antarctic Treaty Consultative Meeting (ATCM), with figures as of 10 April 2026, breaks the season down as follows:

• Seaborne, landing: 73,372
• Cruise-only (no landings): 27,217
• Air-cruise: 11,764
• Deep field: 1,106
• Yacht: 59

IAATO’s vessel overview counts 68 ships and yachts on 579 voyages, compared with 77 vessels and 562 voyages in 2024–25. Landed passengers rose from 80,455 to 85,195. Nearly all of the decline came from cruise-only passengers, which fell from 36,769 to 27,217. The drop was in ships that sail past Antarctica without landing anyone, not in interest in going ashore.

Demand indicators point the same way. In Virtuoso‘s 2027 Luxe Report, released 30 September, Antarctica has held the No. 1 adventure spot since 2024 and ranks No. 2 among destinations on the rise and No. 4 among cruise itineraries.

Where the crowding is

The pressure shows up at specific sites rather than in the overall total. IAATO’s landing-site report for 2025–26 records 3,425 landings across 206 Peninsula sites. The top five sites took about 26.5 percent of all landed visits and the top 20 about 65.5 percent. The most visited were:

1. Neko Harbour: 210 visits
2. Whalers Bay: 191
3. Portal Point: 185
4. Cuverville Island: 169
5. Damoy Point / Dorian Bay: 153

Operators work within a fixed set of rules, which MercoPress summarizes from IAATO’s reporting: one ship at a site at a time, no more than 100 people ashore from a vessel at once, guides at a ratio of one to 20, and no landings at all from ships carrying more than 500 passengers. When dozens of ships are chasing the same well-known sites over the same holiday weeks, those rules decide who gets ashore, where and for how long.

2026–27: steady capacity, not a boom

IAATO’s preliminary estimates for the coming season, also dated 10 April 2026, show 105,462 vessel passengers on 580 voyages, about the same number of voyages as last season. The estimates break down as 65,055 traditional seaborne passengers to the Peninsula on 45 vessels, 13,498 air-cruise passengers on 19 vessels, 26,238 cruise-only, 235 on yachts and 1,436 to other regions. IAATO notes the figures are preliminary and leave out its new provisional operators, so the final count is likely to be higher. Deep-field and air operators estimate 1,492 clients, up from 1,106.

The fleet is changing at the margins. Antarctica21‘s Magellan Discoverer, a 94-metre hybrid-electric sister to its Magellan Explorer, is scheduled to start Antarctic service in December 2026, carrying 88 guests on air-cruises and 96 on sea voyages, Expedition Cruising reported on 30 September. Terra Nova Expeditions has swapped the MS St. Helena for the Terra Nova Adventurer (formerly the MS Expedition) because, according to Cruise Industry News, the St. Helena could not reposition safely from the Persian Gulf on schedule.

The rules debate continues

The 48th ATCM, held in Hiroshima from 11 to 21 May 2026, discussed tourism at length but did not adopt binding rules. Japan’s foreign ministry said “concrete methods of regulation, management, and monitoring were discussed” and that the talks would continue between meetings. An analysis by the Institute for China-America Studies noted that the meeting did not set visitor caps, agree a tourism fee or decide how to measure cumulative impact. The Antarctic and Southern Ocean Coalition said in a statement that the parties “cannot continue relying on largely voluntary guidelines while commercial tourism operations expand rapidly across the continent.”

In the meantime, the industry is tightening its own rules. IAATO reports eight new or updated visitor site guidelines, a new Antarctic Expedition App, and a new voluntary geofenced whale area with a 10-knot speed limit around the South Orkney Islands.

For advisors

• Book 2027–28 holiday departures now. Voyage numbers are flat while landings are rising, and the Christmas and New Year sailings fill first. Waiting lists are the realistic fallback for 2026–27 peak dates.
• Sell the small-ship premium on landings, not luxury. With no more than 100 people ashore from a vessel at a time, the smaller the ship, the less clients wait for their turn ashore. Ask the line how many landings a voyage plans and how they are rotated.
• Steer away from cruise-only for clients who want to step ashore. It can suit a scenic-cruising client, but it isn’t the same product. Make the difference explicit at quote stage.
• Watch the Treaty talks. Caps, fees or permitting are still under discussion after Hiroshima. Any of them would change pricing and availability for later seasons, so build flexibility into deposits for 2028 and beyond.
