A luxury cruise line is going deep into the rainforest. Seabourn has unveiled "Amazon Explorer: Rivers & Rainforests", a 30-day sailing aboard the Seabourn Quest, running roundtrip from Miami from November 18 to December 18, 2028. The itinerary hits 15 destinations across seven countries and lands in the line's Ruby Jubilee year — Seabourn's 40th anniversary — which the company is marking with extended, expedition-flavoured itineraries.

The centrepiece is scenic cruising on the Amazon River itself, but the ports are the real draw. In Brazil, guests get an overnight in Manaus, the sprawling river city famous for its ornate opera house, markets and restaurant scene, plus calls at Santarém, near the striking confluence where the Amazon and Tapajós rivers run side by side without mixing. There's also Parintins — home of one of Brazil's biggest folk festivals — and Boca da Valeria, a tiny riverside community hemmed in by rainforest that offers a rare, unvarnished look at daily life along the river.

Beyond Brazil, the itinerary stops at Devil's Island in French Guiana, the remote former penal colony with a dramatic and dark history, and finishes the flavour contrast with a call at Gustavia in St Barts, where Swedish colonial and French Creole buildings line a harbour now filled with boutiques and cafés. Going from rainforest villages to St Barts beach clubs in one trip is a fairly unusual pairing, even by long-cruise standards.

The Amazon sailing also opens a busy stretch for the Seabourn Quest. After the river voyage, the ship runs two 10-day Caribbean holiday cruises, then leaves Miami on January 7, 2029 for a 138-day world cruise — "Iconic Islands & Remote Horizons". So if a month on the Amazon feels like too much of a commitment, there are shorter ways to sample the ship around the same period.

Why it matters: river-and-rainforest itineraries are still relatively rare for mainstream luxury lines, and a 30-day format with an overnight in Manaus gives far more depth than a typical port-of-call visit. Seabourn's president Mark Tamis framed it as taking guests "into the heart of the Amazon" while keeping the line's signature small-ship, personalised service. For travellers who want expedition-style scenery — rainforest, river communities, remote islands — without giving up fine dining and comfort, this is the kind of sailing that sits nicely between a big-ship cruise and a full expedition charter. Book far ahead if it appeals: anniversary-season itineraries on ships this size tend to move quickly.
