An expedition cruise with a genuinely off-grid route is heading to the South Pacific. Heritage Expeditions has opened bookings for a new 11-day sailing called the Tropical Islands of Fiji, Samoa & Tonga Cruise, running 14–24 March 2027 roundtrip from Fiji aboard the 140-guest Heritage Adventurer.

Fares start from $7,160 per person, and anyone booking before 30 October 2026 gets 20% off — a decent saving if a small-ship Pacific trip is on your list for next year. Given the ship carries just 140 guests, early booking is more than a marketing nudge; cabin choice genuinely narrows fast on itineraries like this.

The route strings together three island nations plus a territory most travellers never see: Fiji, Tonga, Samoa and the remote French collectivity of Wallis and Futuna. On the itinerary are the sculpted limestone islands of Fulaga in Fiji's Lau group, the rainforest trails of Bouma National Heritage Park on Taveuni, and Samoa's Tafua Rainforest Reserve. In the water, there's snorkelling at Palolo Deep Marine Reserve off Apia and at Swallows Cave, the famous sea cave in Tonga's Vava'u group famous for its light and swarms of fish.

Wallis and Futuna is arguably the most unusual stop. Rarely visited by cruise ships, the islands offer lagoons, WWII remnants and some of the most intact Polynesian traditional culture anywhere in the Pacific — the islands never became a major tourist destination, and the voyage leans into that.

Wildlife is a real draw here, not just beach filler. The expedition team highlights endemic species you'd struggle to see independently, such as the Samoan Flying Fox and the Fijian Monkey-faced Bat, a fruit bat found on exactly one Fijian island. Birders get the headline act: the Tooth-billed Pigeon, Samoa's national bird and one of the closest living relatives of the Dodo — a critically endangered species with a population so small that simply glimpsing one is a serious twitching tick.

Who is this for? It suits travellers who want the expedition-cruise format — zodiac landings, guides, small groups — applied to warm-water destinations rather than the usual polar routes. You get jungle hikes and reef snorkelling in the morning and white-sand beaches in the afternoon, with Polynesian culture woven through. If you've done a Galapagos or Antarctic expedition trip and want the same style closer to the equator, this is a tidy fit. It's also priced well below what most polar expedition sailings cost, so the entry point is comparatively gentle.

March timing lands in the tail of the South Pacific cyclone season, which is worth weighing against the attractive early-booking discount — expedition ships monitor weather closely and itineraries can flex. Independent travellers should also note how hard some of these stops are to reach on their own: getting to Wallis and Futuna or Fiji's outer Lau islands by scheduled transport takes serious time and patience, which is exactly what the ship format solves.
