There are places on Earth so rich in biodiversity that they defy comparison. The Coral Triangle is one of them. Spanning nearly six million square kilometers across Indonesia, Malaysia, the Philippines, Papua New Guinea, Timor-Leste, and the Solomon Islands, the Coral Triangle is often called the “Amazon of the Seas.” It’s home to 76% of the world’s coral species, over 2,000 species of reef fish, and a wild variety of experiences. From remote atolls to volcanic coastlines, the Coral Triangle is a world best discovered slowly and with intention.
With EYOS, every expedition through this extraordinary region is deeply immersive and endlessly customizable. Traveling by expedition yacht allows you to move through the Coral Triangle with flexibility, guided by marine biologists, conservationists, and local experts who know these waters like home. This is not a standard voyage. It’s an intimate encounter with one of the last truly wild marine ecosystems on Earth.

Dive into Discovery
The Coral Triangle is often described as the epicenter of marine life on Earth for good reason. This region covers less than 2% of the planet’s ocean surface but contains nearly 30% of the world’s coral reefs. The diversity you can expect to see there includes:
- 600+ species of reef-building coral (more than 75% of all known species)
- 2,000+ species of reef fish, from clownfish to barracuda
- Six of the world’s seven marine turtle species
- Endangered dugongs, blue whales, whale sharks, and manta ray
- A vast array of mollusks, crustaceans, sea snakes, and marine mammals
But biodiversity isn’t the only marvel. The Coral Triangle is also a place of extraordinary variety in underwater terrain including steep drop-offs, volcanic pinnacles, seagrass beds, mangrove estuaries, coral atolls, and black sand slopes. It’s a living, breathing system where the ecological interactions are as complex as a rainforest and where much is still unknown.
Put simply, the Coral Triangle is a diver’s dream. Every dive site offers something different: the kaleidoscopic coral gardens of Raja Ampat, the dramatic vertical drop-offs of the Banda Sea, the macro wonderland of Lembeh Strait. You might find yourself drifting with schooling barracuda one morning and photographing a tiny nudibranch the next.
Our dive operations are tailored to your experience level and interests. We use custom dive tenders, carry state-of-the-art equipment, and always operate with safety as our highest priority. Whether you’re logging your first open water dive or your thousandth, our team of dive masters and marine scientists are by your side, pointing out rare species, interpreting behaviors, and ensuring every moment underwater is as safe as it is unforgettable.

Paddle, Swim, Kayak, Repeat
Not all exploration happens below the surface. The Coral Triangle’s warm, protected waters are perfect for paddleboarding at sunrise through ancient mangrove forests, kayaking along jungle-lined shores, or snorkeling over technicolor reefs just meters from your yacht.
Every EYOS yacht is equipped with a wide array of water toys and equipment, including paddleboards, kayaks, and top-of-the-line snorkel gear. Want to drift along the edge of a reef at golden hour, watching reef sharks and parrotfish dart beneath you? Or perhaps a slow morning paddle across a glassy lagoon? It’s all within reach, and always on your own terms.

Above the Waterline
While the Coral Triangle’s underwater life is its main draw, the landscapes and cultures above sea level are just as compelling. Trek inland on Papua’s islands to spot birds of paradise in the wild, their iridescent plumage flashing through the canopy. Visit remote villages in the Solomon Islands, where carved dugout canoes still glide across the bays and islanders share oral histories passed down for generations.
Because we travel by expedition yacht, we can anchor off hidden beaches where few travelers ever set foot. Spend the afternoon combing the shoreline for shells, hiking to a waterfall, or enjoying a picnic prepared by your onboard chef. Every land excursion is coordinated with sensitivity and respect, ensuring authentic, low-impact experiences that honor both local ecosystems and cultures.

A Floating Basecamp
Your expedition yacht is more than a mode of transport — it’s a sanctuary of comfort in the most remote corners of the world. Return from an exhilarating dive or jungle hike to warm towels, fresh juice, and a lunch of freshly caught seafood. Spend the afternoon in the spa with a range of wellness treatments, or relax on the sundeck with a cold drink as the sunset gives way to a sky full of stars.
We operate the most capable expedition yachts in the world. These vessels are designed to deliver five-star comfort without compromising on safety, sustainability, or reach. With onboard dive centers, heli-decks (on select yachts), and a suite of tools for exploration, your basecamp is always within easy reach, no matter how far off the grid your day takes you.
