If a week at sea feels like a teaser, Atlas Ocean Voyages has a longer answer. The expedition cruise line has unveiled a Grand Voyage Collection for 2027 and 2028: 16 Extended Journeys of 14 to 26 nights, plus a new 31-night Extraordinary Expedition sailing from the High Arctic all the way to Portugal.

The idea is simple. Each Extended Journey chains together two or three consecutive voyages on Atlas's small ships — the World Navigator, World Traveller and World Voyager — so you get one long, seamless trip instead of booking back-to-back cruises yourself. The line's CEO, James A. Rodriguez, framed it as the luxury of time: seeing fewer places rushed, more places properly.

For 2027 there are six itineraries between 16 and 25 nights. Highlights include a 23-night run from Málaga to Valletta linking the Spanish, French and Italian Rivieras with Malta (departing 23 April), a 25-night Lisbon-to-Oslo passage through Bordeaux and England (7 May), and an 18-night Iceland-to-Svalbard Arctic sailing from Reykjavík to Longyearbyen on the World Voyager (5 June). A 16-night Tuscan-to-Venice trip via Croatia closes out the year in August.

The 2028 programme is bigger: ten itineraries across three themes. In the Mediterranean and Adriatic, a 17-night Rome-to-Lavrion voyage departs 31 May and is timed around the Monaco Grand Prix, with a follow-up 17-night leg on to Istanbul. Atlantic Coast and Northern Europe options stretch from a 15-night Barcelona-to-Lisbon hop to a hefty 26-night Lisbon-to-Stockholm epic via London and Copenhagen on the World Navigator. There's also a 23-night Bordeaux-to-Reykjavík route pairing French wine country with London and Iceland, and a Stockholm-to-Longyearbyen Arctic run the same length.

The headline act is the 2028 Extraordinary Expedition: 31 nights aboard the World Voyager, departing Longyearbyen in Svalbard on 5 September 2028 and finishing in Lisbon. It stitches three voyages into one, so you watch the scenery flip from polar wilderness to Iberian coastline over a month at sea.

Why care? Atlas operates small, yacht-style expedition ships, so these itineraries reach ports the mega-ships skip — think Svalbard, the Canary Islands and smaller Adriatic stops. The long formats suit travellers with real time to spare, especially retirees or remote workers who'd rather unpack once. Bookings this far out also mean early-bird cabin choice on ships that carry relatively few passengers, and combining voyages often works out better value than separate bookings. If you've been circling the Arctic or dreaming of a slow Mediterranean season, these are built exactly for that.
