Reasons to Explore These Epic Sites When Scuba Diving in Palau
Scuba diving in Palau is one of the most rewarding underwater experiences in the world, and a liveaboard gives you access to its most remote and action-packed sites. These islands sit at the crossroads of powerful ocean currents that funnel marine life into channels, walls, caverns, and blue holes unlike anything else in Micronesia. For divers who want to see Palau at its best, a liveaboard itinerary brings the region’s signature drifts, reef-hook lookouts, and deep south outposts within easy reach.
A liveaboard also maximizes your time in the water. Instead of long boat rides from shore each day, you wake up close to the next dive site. That means more dives, easier scheduling around tides and currents, and a better chance of witnessing the manta trains, shark patrols, and schooling fish that make Palau so unforgettable. It is a convenient way to explore the Rock Islands, visit the southern walls, or cross channels that land-based operators often struggle to reach.
Another advantage is the variety you can experience in a single trip. Palau’s reefs include steep walls, coral gardens, shark-heavy corners, and WWII wrecks. Some sites reward early morning dives, others work best with strong incoming currents, and some require calm seas to access. A liveaboard grants you access to the right place at the right time, creating a seamless flow of diving that few destinations can match.
1. Blue Corner and Blue Holes
Blue Corner is Palau’s signature drift site and one of the most iconic shark encounters on the planet. The site sits at the edge of a reef plateau where strong currents pull in jacks, snappers, and large predatory fish. Divers often use reef hooks to hold position along the edge of the plateau while grey reef sharks circle just a few feet away. The currents can change quickly, which is why many divers appreciate having a liveaboard schedule that adapts to conditions.
Blue Holes sits right next to Blue Corner and adds an entirely different dimension to the experience. The site is made up of four vertical openings that drop into a cathedral-like cavern filled with ambient blue light. You can explore the chamber, exit through one of several swim-throughs, and often finish your dive drifting toward Blue Corner itself. It is a dramatic mix of overhead environment and classic Palauan drift diving.
Highlights of Blue Corner and Blue Holes include:
Holding position with a reef hook as dozens of grey reef sharks patrol the current line
Entering Blue Holes through a wide opening that reveals beams of blue light
Drifting along soft corals, sea fans, and passing schools of barracuda
Watching turtles feed or rest along the plateau
The combination of these two sites gives divers a taste of Palau’s signature elements. You get a cavern experience, a powerful drift, and some of the most reliable shark encounters in the region. A liveaboard gives you the flexibility to time the currents and revisit the site if conditions line up for an exceptional dive.
2. German Channel
German Channel is one of the best places in Palau to see manta rays up close. This man-made channel was cut through the reef decades ago and now serves as a natural highway for nutrient-rich water. Manta rays often gather at cleaning stations inside the channel, making it a go-to site for divers who want to observe these graceful animals as they glide in for a tune-up by cleaner fish.
The channel is also home to grey reef sharks, turtles, and a wide variety of reef fish that congregate along the sandy bottom and coral outcrops. Current direction shapes every dive here. Incoming currents often bring more life, while outgoing tides may offer gentler conditions for those still building confidence in stronger water movement.
What divers love about German Channel:
Manta rays circling at cleaning stations
Grey reef sharks cruising along the sandy bottom
Consistent visibility that often reaches 120 ft
Colorful coral bommies packed with reef fish
German Channel remains one of the most rewarding dives in Palau because every visit feels a little different. A liveaboard schedule helps match your dives to the peak tidal periods, giving you the best chance of seeing mantas at their most active.
3. Peleliu Wall and Peleliu Cut
Peleliu Wall is known for its vertical drop-offs, dramatic overhangs, and the chance to spot rare pelagic species. Located at the southern edge of Palau, this site often experiences strong currents that bring in big fish. Trevallies, barracuda, sharks, and even the occasional bull shark or hammerhead may appear along the wall. The site’s remote nature makes it a valuable addition to longer liveaboard cruises.
Peleliu Cut is just around the corner and offers a fast-paced drift along the edge of the reef. The channel drops quickly into deeper water where schools of snapper, surgeonfish, and jacks gather. Because conditions can be powerful, many divers rely on experienced guides to find the safest and most rewarding route along the wall and through the cut.
Why Peleliu is a liveaboard favorite:
Chance to see hammerhead sharks in cooler months
Deep blue water along the wall packed with pelagic life
High-speed drifts that reveal large schools of reef fish
Healthy soft corals, sea fans, and dramatic topography
These sites offer some of the most exhilarating diving in Palau. A liveaboard, like the Palau Aggressor II, allows you to reach Peleliu more easily and to time your dive with the tides so you experience the best currents without unnecessary risk.
4. Ulong Channel
Ulong Channel is famous for one of the most enjoyable drift dives in Palau. When the tide is right, scuba divers glide over hard coral gardens and into a shallow sandy channel lined with lettuce corals and thriving reef life. The dive is gentle, colorful, and filled with marine activity, which makes it equally appealing for those gaining comfort in drift diving and divers with years of experience.
The outer reef leading toward the channel mouth can also deliver shark sightings and schools of snapper and barracuda. Once inside the channel, the scenery shifts to compact coral structures, giant clams, and sandy stretches where rays sometimes rest. Timing is everything because this site depends heavily on incoming currents to bring in clear water and marine movement.
Highlights of Ulong Channel include:
A smooth, scenic drift that is easy to enjoy
Hard coral formations that cover the channel floor
Frequent sightings of turtles, sharks, and schooling fish
Clear incoming water that brightens the entire landscape
Ulong Channel combines excitement with accessibility, and a liveaboard maximizes your chances of diving it at the most beautiful time of day. When the sun is high and the current is steady, this site becomes one of Palau’s most memorable underwater rides.
5. The Big Drop Off
One of Palau’s most spectacular wall dives, The Big Drop Off stretches from shallow reef tops to over 935 feet (285m) into the blue. It is widely regarded as one of the finest vertical walls in the Pacific. Divers hovering along this vertical expanse are treated to a kaleidoscope of life, from dense schools of anthias and butterflyfish to giant gorgonian fans, soft corals, and leather corals. Hawksbill turtles and passing white tip and grey reef sharks add motion to the scene, while lionfish, stonefish, nudibranchs, and leaffish occupy the fissures and crevices along the wall.
The site can be drifted in either direction depending on current, and each approach offers a slightly different perspective on this stunning underwater canyon. As you descend and follow the wall, the sheer scale of the drop becomes apparent, yet divers are rarely distracted from the vibrant life surrounding them. Angelfish, including dwarf, emperor, regal, and keyhole species, dart between corals, and occasional nurse and leopard sharks can be spotted resting on the sandy floor at the base of the wall.
Reasons divers love The Big Drop Off:
Stunning vertical wall with over 935 feet of depth
Thriving marine life including sharks, turtles, and colorful reef fish
Large gorgonian fans and dense soft corals decorating the wall
Drift diving opportunities with strong but manageable currents
The Big Drop Off is a must-see for anyone seeking epic scuba diving in Palau. Its dramatic depth, spectacular biodiversity, and sheer visual impact make it a highlight on almost every liveaboard itinerary that includes Ngemelis Island. Divers leave with the sense of having experienced a true marine cathedral, where the scale of the drop matches the richness of life along the wall.
