Palau diving is a world-renowned adventure for anyone eager to explore vibrant coral reefs, vast schools of fish, and encounters with sharks and manta rays. The waters surrounding this Pacific paradise are among the most biodiverse in the world. From the iconic Blue Corner to the remote reefs of the Deep South, Palau offers experiences that leave divers in awe. A liveaboard cruise is the ideal way to explore these waters because it provides multiple dives per day, flexibility to visit far-flung sites, and an immersive underwater experience.
The marine life in Palau is truly extraordinary. Over 1,500 species of fish and 700 species of coral and sea anemones thrive in nutrient-rich waters where 3 major ocean currents converge. Drift dives bring pelagics into view while reefs host everything from tiny nudibranchs to massive Napoleon wrasse. The region also offers unique snorkeling experiences in Jellyfish Lake and the chance to dive sunken World War II wrecks, combining natural wonder with historical intrigue.
Palau liveaboards typically range from 7 to 10 nights, covering famous dive sites like Blue Corner, German Channel, Peleliu, and remote locations such as Helen Reef. These cruises combine adventure with comfort, offering spacious decks, cozy cabins, and easy access to world-class diving. Whether you are hooking onto a reef to observe passing sharks or drifting along vertical walls, a liveaboard allows you to experience Palau diving fully and efficiently.
Blue Corner is one of the most iconic dive sites in Palau. Known for its dramatic walls and nutrient-rich currents, it offers some of the best drift diving in the world. The currents funnel schools of jacks, snappers, and barracuda past reef hooks, while grey reef sharks patrol the blue. On rare occasions, divers may spot hammerhead sharks, manta rays, or whale sharks, creating an unforgettable underwater spectacle.
Blue Holes is just a short distance from Blue Corner and extends the experience into caverns and vertical shafts. Sunlight piercing the holes illuminates soft corals and smaller reef fish, creating a stunning visual effect. Some of the holes are suitable only for experienced cavern divers, but even in the less technical areas, reef hooks allow you to watch pelagics and sharks glide past in the current.
Highlights of Blue Corner and Blue Holes:
Drift diving at these sites is both thrilling and educational. Divers learn to move efficiently in currents while observing complex predator-prey interactions. Multiple dives at Blue Corner and Blue Holes reveal the full diversity and scale of Palau’s marine ecosystems.
German Channel is a shallow channel cut through a reef during the early 20th century, now famous for its cleaning stations. Manta rays and sharks hang in the current while small cleaner fish remove parasites from their skin. This interaction provides a rare and fascinating opportunity to observe natural reef behavior in action.
Descending along the reef slope from 35 ft to 130 ft, divers encounter sandy patches, rocky outcrops, and colorful hard corals. Schools of jacks, barracuda, and eagle rays swim against the nutrient-rich currents, creating a dynamic underwater scene. Night dives add a new layer of discovery, with garden eels, mantis shrimp, jawfish, and shrimpgoby pairs actively tending to their burrows.
Highlights of German Channel:
German Channel combines action with subtle reef interactions. Hanging on with a reef hook gives divers a front-row view of this spectacular ecological activity, making it one of the most memorable dives on any Palau liveaboard itinerary.
Peleliu Wall and Peleliu Cut provide a mix of historical significance and thrilling marine encounters. Once a World War II battleground, these sites are now home to abundant fish and shark populations. Diving here allows exploration of both dramatic reef slopes and caverns filled with sea fans, black corals, and long sea whips.
Divers often hook on at 30 ft to watch grey reef and whitetip sharks patrol the area, before moving down to 100 ft to explore deeper recesses of the reef. Currents at Peleliu Corner are some of the strongest in Palau, where bull sharks, tiger sharks, and whale sharks may pass by. Schools of pyramid butterflyfish, Moorish idols, and anthias provide a vibrant display of color.
Highlights of Peleliu Wall and Cut:
Peleliu showcases the power and beauty of Palau diving. The combination of historical context, big fish action, and colorful reef life creates a dive experience that is both exhilarating and visually stunning.
The Big Drop Off near Ngemelis Island features a wall that drops from shallow reefs to over 900 ft. The wall is covered with soft corals, sponges, and gorgonian fans, creating a vertical mosaic of color. Sharks patrol the blue, and hawksbill turtles often rest on ledges, providing divers with unforgettable encounters.
The New Drop Off is a corner dive where two reef walls meet and descend to approximately 500 ft. Reef hooks allow divers to hang in the current and observe grey reef sharks, eagle rays, and schools of barracuda. The wall gradually transitions to a gentle slope with Napoleon wrasse and snappers, making it an excellent mix of pelagic action and reef exploration.
Highlights of Big Drop Off and New Drop Off:
These drop-offs highlight the scale and diversity of Palau diving. Divers can experience thrilling currents, vast walls, and a full spectrum of marine life in a single dive, combining action, beauty, and technical challenge.
Ulong Channel is a shallow dive site with a maximum depth of 45 ft, yet it boasts remarkable biodiversity. Reef hooks at the channel entrance allow divers to observe grey reef and white tip sharks passing by while currents funnel pelagics through the channel.
The sandy channel floor features coral bommies and a massive lettuce coral patch rising over 25 ft, home to countless small reef fish. Schools of jacks, batfish, and barracuda move along the channel slopes, while full moon dives from April to July showcase spawning groupers. Occasionally, stingrays and titan triggerfish defending nests add excitement to the dive.
Highlights of Ulong Channel:
Ulong Channel offers long, immersive dives with abundant marine life. Its shallow depth allows divers to extend bottom time while experiencing both pelagic action and rich reef biodiversity.
Helen Reef is a remote atoll over a full day from Koror. Its protected status has preserved pristine reefs teeming with life. Divers encounter dense schools of reef fish, reef sharks, manta rays, and pelagics including tuna, trevally, and rainbow runners. Large oceanic sharks patrol the outer slopes, creating a truly exhilarating diving experience.
The reef supports over 500 species of fish, 282 hard coral species, and 43 soft coral species. Currents are strong, making dives suitable for more experienced divers, and the sheer biodiversity rivals any site in the Pacific. Its remoteness ensures minimal human impact and maximizes the chance of seeing untouched reef ecosystems.
Highlights of Helen Reef:
Helen Reef offers an unparalleled Palau diving experience. Its remoteness, thriving marine life, and strong currents make it a must-visit destination for divers seeking adventure, discovery, and a glimpse of one of the Pacific’s most untouched reefs.
Palau liveaboards are the ultimate way to experience Palau diving. By staying on a liveaboard, divers can access both the most famous dive sites and the more remote locations that are impossible to reach on day trips. Most liveaboards depart from Koror and run trips ranging from 7 to 10 nights, offering multiple dives per day. This flexibility allows divers to maximize their underwater time and explore the full range of Palau’s reefs, walls, channels, and wrecks at a relaxed pace.
These vessels combine adventure with comfort. Spacious decks provide plenty of room for pre-dive preparation and socializing, while cabins are designed for rest and privacy after a long day underwater. Many liveaboards include saloons for dining and relaxation, as well as al fresco areas for enjoying Palau’s stunning tropical scenery. Meals, dive briefings, and guided trips are all organized onboard, letting divers focus on the experiences beneath the surface rather than logistics.
Beyond convenience and comfort, liveaboards in Palau emphasize sustainability and responsible diving. With the country’s waters designated as a large marine reserve, operators follow strict practices to minimize impact on the environment, from avoiding damage to reefs to ensuring safe interactions with sharks, rays, and other pelagic species. Traveling by liveaboard also reduces repeated fuel use from daily land-based trips, making this option an environmentally conscious choice for exploring Palau’s unique underwater ecosystems.
Palau diving offers experiences unlike any other, from Blue Corner’s dramatic drift dives to the historical wrecks of Peleliu. Sharks, manta rays, turtles, and massive schools of reef fish combine with colorful corals to create unforgettable underwater encounters. Each dive presents a mix of beauty, excitement, and the wonder of a thriving marine ecosystem.
Liveaboard cruises make the most of Palau diving. They allow access to remote sites like Helen Reef, provide multiple dives per day, and offer opportunities to observe marine life in its natural habitat.
