by Koror, the bustling hub of Palau, is not just a gateway to the nation’s beautiful islands, but a world-renowned destination for diving enthusiasts. Located in the heart of the Pacific, Koror offers access to some of the most extraordinary dive sites in the world, with its surrounding waters teeming with diverse marine life, stunning coral reefs, and intriguing underwater landscapes. This article takes an extensive look at some of the top diving hotspots in Koror, showcasing why Palau is considered a diver’s paradise.
1. Blue Corner: A Dive Like No Other
One of the most famous dive sites not just in Palau but globally, Blue Corner is often touted as a “must-do” dive for any serious diver visiting Koror. Located at the western edge of Palau’s barrier reef, this site offers an exhilarating mix of strong currents, dramatic drop-offs, and abundant marine life.
At Blue Corner, divers can expect to encounter large schools of fish, such as jacks, barracudas, and snappers. It is also a prime spot for spotting reef sharks, manta rays, and even the occasional hammerhead shark. The currents bring an abundance of plankton, attracting a variety of pelagic species, which makes the site vibrant and dynamic.
The dive typically involves hooking onto the reef with a reef hook to stay in place while enjoying the action of the marine life swirling around. The reef’s ledges and walls drop off into the deep blue, providing breathtaking views. Soft corals and sea fans decorate the underwater landscape, creating a striking contrast against the crystal-clear waters.
2. German Channel: Manta Ray Magic
The German Channel, an artificial channel created by German colonizers to facilitate phosphate transportation, is now one of the most famous dive sites for manta ray sightings. Mantas visit this channel to feed on plankton and get cleaned by smaller fish at cleaning stations.
The German Channel is shallow, making it an ideal spot for divers of all skill levels to witness manta rays gracefully gliding through the water. In addition to mantas, divers may spot grey reef sharks, eagle rays, and a variety of smaller reef fish.
What makes the German Channel unique is the opportunity to observe cleaning station behavior up close. At these cleaning stations, smaller fish such as wrasse and gobies remove parasites and dead skin from manta rays and other large marine animals, providing divers with a unique natural spectacle.
3. Ulong Channel: Nature’s Drift Dive
Ulong Channel is widely regarded as one of the best drift dives in the world. This channel is located between the Ulong Island and Ngemelis Island and provides an exhilarating ride with strong currents that sweep divers along the channel. The dive begins with a descent into a coral garden, followed by drifting along a channel teeming with life.
The coral formations in Ulong Channel are stunning, with a wide variety of hard and soft corals. Divers often encounter large schools of barracudas, snappers, and trevally. One of the highlights of the dive is the chance to spot sharks resting on the sandy bottom or cruising along the reef.
At the mouth of the channel, divers can also witness the seasonal spawning of groupers, which attracts large numbers of predatory fish. The sheer abundance of marine life and the thrill of the drift make Ulong Channel a top choice for adventurous divers.
4. Blue Holes: Enter the Underwater Cathedral
Blue Holes is a stunning dive site just a short distance from Blue Corner, often done as a combined dive. The dive begins with a descent into a series of underwater caverns and tunnels, which lead to a spectacular blue cathedral-like chamber. The natural light filtering down through the holes in the ceiling creates a magical atmosphere, making it a must-visit for underwater photographers.
Inside the caverns, divers can explore the intricate walls and ceilings adorned with soft corals and sponges. There is also a chance to spot bumphead parrotfish, turtles, and smaller reef fish darting around the formations. As divers exit the cavern, they are greeted by the open sea, where they can continue the dive along the outer wall of Blue Corner, encountering larger pelagic species.
5. Chandelier Caves: A Unique Cavern Dive
For divers seeking a unique adventure, Chandelier Caves offers an exciting mix of cavern diving and natural beauty. Located close to Koror, this series of caves gets its name from the stalactites hanging from the ceilings, resembling chandeliers. The dive takes you through a network of interconnected chambers filled with clear, still water, providing an otherworldly diving experience.
The caves are relatively shallow, making them accessible to divers of different skill levels. Inside the caverns, the reflection of the stalactites in the water creates a surreal visual effect. Although there is not much marine life inside the caves, divers may spot crustaceans like lobsters and shrimp. The exit of the caves leads to a shallow coral garden, where divers can enjoy a more traditional reef dive after exploring the caverns.
6. Peleliu Wall: WWII History Meets Marine Life
Located near Peleliu Island, Peleliu Wall is not only a great dive site but also steeped in history. Peleliu was the site of a major World War II battle, and remnants of the conflict can still be found on the island above water. Below the surface, however, Peleliu Wall offers one of the most dramatic vertical drops in Palau, plunging hundreds of feet into the abyss.
This wall dive is famous for its shark sightings, with grey reef sharks, whitetip reef sharks, and the occasional hammerhead patrolling the deep blue. The wall is covered in gorgonian sea fans, sponges, and colorful corals, creating a beautiful backdrop for divers. Strong currents can make this dive challenging, but they also bring in a wide variety of pelagic species, including tuna, barracuda, and manta rays.
Peleliu Wall is a great choice for advanced divers looking for an exciting and historically rich dive site.
7. Turtle Cove: A Macro Photographer’s Dream
While Palau is famous for its large pelagic species, Turtle Cove offers an excellent opportunity for divers interested in macro photography. This site, located near Ngemelis Island, is known for its healthy coral gardens and an abundance of small marine creatures. Nudibranchs, pygmy seahorses, and a variety of shrimp and crabs can be found hiding among the corals, making this a paradise for macro enthusiasts.
Turtle Cove also lives up to its name, with frequent sightings of green sea turtles and hawksbill turtles grazing along the reef. The dive typically begins with a drop into a hole that leads to a cavern, and then divers follow the reef wall, where they can enjoy the vibrant marine life and pristine corals.
8. Siaes Tunnel: A Deep Dive into the Abyss
Siaes Tunnel is one of Palau’s more advanced dive sites, offering an exciting dive for those looking to explore deeper waters. The tunnel is located at around 90 feet (27 meters) and features a wide entrance that leads into a dark, mysterious tunnel running through the reef. Inside, divers can spot sleeping sharks, bumphead parrotfish, and Napoleon wrasse.
The walls of the tunnel are lined with soft corals, sea fans, and sponges, adding color to the otherwise dim environment. The dive then continues along a vertical wall where divers can encounter larger pelagic species cruising in the open blue.
