Silversea's Silver Cloud has set sail on one of the season's most ambitious itineraries: a 77-day expedition from Perth, Australia, to Valparaiso, Chile, spanning 57 ports across 11 countries. The Grand South Pacific Expedition departed in August and will conclude on November 4, 2026, offering passengers a rare chance to explore some of the world's most remote and coveted destinations in a single sailing.
The voyage stitches together multiple regions that typically require separate bookings. Travelers will experience Australia's ports, venture into the South Pacific's island territories including Bora Bora, and finish in South America, all without returning to a home port. Silver Cloud, Silversea's smallest ship, carries only 296 passengers, allowing access to smaller ports and anchorages unavailable to larger vessels.
A journey of this length and scope appeals to experienced cruisers seeking immersion rather than rapid port-hopping. The expedition format means passengers spend extended time in each region, with the itinerary divided into segments that allow for thematic exploration. For those considering a similar voyage, booking this type of extended sailing requires advance planning around visas, time off work, and cabin preferences. Silversea typically prices expedition cruises at a premium, and cabins on long voyages fill early.
Cruisers interested in ultra-long sailings should know that availability is limited. These 70+ day itineraries operate only once or twice yearly on most lines, and Silver Cloud's capacity of under 300 passengers means spots vanish quickly. For future planning, travelers should bookmark Silversea's expedition calendar and subscribe to alerts well before the next such voyage is released, as similar routes often repeat annually or biannually.
