Most cruise itineraries get a light annual tweak — a new port here, an extra overnight there. So when Norwegian Cruise Line launched a 16-day "Fire and Ice" voyage linking Hawaii with Alaska, it stood out as genuinely new thinking. Passengers got snorkelling on reefs, lava fields and rainforest at one end, then dog-sledding and glaciers at the other. The only real challenge? Packing for two climates in one suitcase.

That trip got travel writers hunting for other unusual destination pairings, and it turns out there's a small but fascinating crop of them for anyone bored by the usual Mediterranean loop.

Fred Olsen Cruise Lines is running an 87-night Amazon & Antarctica Adventure departing January 2028 — though Antarctica is seen from the deck only, with no landings. For a full-blown contrast, Viking's 81-day Arctic to Antarctic Explorer sails in September 2029 from Nuuk in Greenland all the way to Ushuaia in Argentina. It effectively reinvents world cruising as a vertical journey rather than a horizontal one: down the coasts of Greenland and North America, a warm-up stop in the Bahamas and Jamaica, through the Panama Canal, then along South America's west coast to the Antarctic Peninsula.

Seabourn offers a similar epic with its 94-day Grand Expedition: Pole to Pole, running between Reykjavík and Buenos Aires from August 2027. That one lingers longer in the Caribbean and travels up South America's east coast, with several Brazilian stops mixing tropical heat with polar cold.

If ice itself is the draw, Ponant's icebreaker Le Commandant Charcot is planning something no cruise ship has ever done: a full circumnavigation of Antarctica from January 2028. It pairs the frequently visited Antarctic Peninsula with rarely seen East Antarctica — and everything in between, which ships simply never go to.

For travellers who'd rather not commit to weeks of ice, Atlas Ocean Voyages has a 128-day Grand Odyssey Expedition aboard its new ship Atlas Adventurer, linking Kobe in Japan with Cape Town in South Africa. It calls at 19 countries across 87 ports — Manila, Hong Kong, Melaka, the Maldives, Mombasa, Maputo — a genuinely global sweep of cultures and coastlines.

Why does this matter to holidaymakers? Because if your idea of a cruise has outgrown the standard routes, the industry is finally offering alternatives that reward curiosity. These long-haul itineraries aren't cheap and require serious time off, but they bundle what would otherwise be several separate trips — tropical beaches, wild coastlines, polar wilderness — into one voyage. Book early: first-of-their-kind sailings like a full Antarctic circumnavigation tend to fill fast with expedition enthusiasts.
