Raja Ampat, the cluster of islands off the western tip of Indonesian New Guinea, has a solid claim to being the richest marine environment on Earth — manta rays, whale sharks, sea turtles and reefs packed with species found nowhere else. Yet it barely appears on luxury expedition itineraries, because getting there is genuinely hard. That's precisely its appeal, and the reason a rare sailing dedicated to the region is worth a look.

Swan Hellenic's SH Minerva departs Manila on 6 May 2027 for a 12-night voyage to Sorong, Papua, running through 18 May. The key difference from most expedition cruises: instead of giving Raja Ampat a token day or two en route elsewhere — the approach you'll find on Silversea or Seabourn sailings — this itinerary spends multiple days exploring the archipelago itself.

That time translates into a long list of stops: Kabui Bay and The Passage, the postcard viewpoints of Wayag Island, Pulau Fam, Pulau Penemu, Pulau Kri, Pulau Mansuar, and Misool with Balbulol Lagoon. Above water it's limestone karst islands rising from electric-blue sea, hidden lagoons and uninhabited beaches; below, some of the best snorkelling and diving on the planet. Even non-divers get extraordinary snorkel access. The route also includes a Philippines stop — Bohol, where the tiny, wide-eyed tarsier lives — and ends in Bali, so you can fly home easily or tack on a beach resort stay.

Sailing beats resort-hopping here for a simple reason: logistics. Raja Ampat's dive lodges are excellent but static, while a small ship moves you to a new cove or reef each morning without the transfers. SH Minerva carries roughly 150 guests, and every fare includes at least one excursion per port, Zodiac cruises, onboard naturalists and lectures, oceanfront cabins and 24-hour room service. It's an exploration-focused trip rather than an entertainment cruise.

On price: balcony staterooms start at $9,428 per person through the promoting agency, which is oddly cheaper than an oceanview cabin, and a private promotion bundles in around $2,000 per person of value — $350 onboard credit per person and complimentary premium Wi-Fi. Availability is limited, and sailings this dedicated to Raja Ampat don't come up often.

Who is this for? If you've done Antarctica, the Galápagos or the Kimberley and want the next genuinely remote frontier, Raja Ampat fits the same mould — wild, hard to reach and uncrowded. Snorkellers and divers get world-class water; photographers get scenery that outperforms the Instagram version. Book well ahead: expedition ships this small fill quickly, and May sits at the tail end of Indonesia's dry-ish season, one of the calmer windows for the region.
