Dive Site Intro

   Blue Corner   

Blue Corner is the most famous dive site in Palau due to consistent shark and other pelagic fish presence. The corner is a shallow plateau pointing westward into the Philippine Sea. High currents often run across the plateau generating an amazing food web. 

Sharks aggregate at Blue Corner due to the high currents. Grey Reef Shark, Whitetip Sharks are often found cruising around the cut in groups, even sometimes come extremely close to divers and photographers who are hooked into the reef, allowing great photography and fish watching. Besides Sharks, king mackerel, dogtooth tuna, and giant/ bluefin trevally are also "regular" in the area. 

When the currents are not as strong, theses species will often be spread out over the plateau during weak or non-existent currents. Inside the plateau Napoleon Wrass, schooling big eye trevally, barracuda, anemones, anemonefish , leaf fish, lion fish, turtles, a resident spotted eagle ray, and others can be found on a regular basis. 

  Ulong Channel   

Ulong Channel (Ngrumekaol) is a false channel eroded into the barrier reef west of Ulong Island. The dive is usually done on an icoming tide wherein the wall is on the left, as divers approach the mouth of the channeal where grey reef and whitetip sharks congregate in the current. Along the wall, between 15m/50ft --18m/60ft a marvelous drop off showcases scholling spadefish, gold spotted trevally chasing bigeye scad.  

A stop is usually done a few minutes before drifting into the channel, The ride through the channel at an average depth of 15m/50ft is like a high speed amusement park ride with lots of small reef fish, occasional sharks, threadfin pomopano, various species of grouper, and Barramundi cod found along the way, There are also soft corals, sea fans, and rarely seen lettuce coral. Divers may also see garden eel or sleeping shark on the bottom while doing safety stop by the end of the channel. 

There is a multitude of additional sea life, which may be seen at any given time while diving the channel. During April to September there species of groupers come to the channel where they aggregate and spawn with peak numbers around the time of the new moon . Diver can easily see hundreds of groupers on a drift through the channel at these time. 

  Blue Hole  

This site has a large cavern with four holes on top of the reef allowing natural light to filter in and additional entrances along the reef wall. The cavern and holes were formed years ago when water levers were much lower than today. When the sea is calm, divers usually enter the cavern through one of the holes on the top of the reef flat and descend slowly through a wide tube that has many lace hydroids growing on the walls. Soldierfish and fairy basslets are found inside the tube. Once divers descend to about 18 meters, inside the cavern they will notice thick beams of natural light entering from the four skylights above. No current is present inside the cavern. 

2 exits are readily apparent. The larger one is between 20 and 40 meters and the other one is around 15 meters. Divers usually spent 10-15 min inside the cavern and then begin drifting either outgoing current with the wall on the left towards Blue Corner or incoming towards Temple of Doom with the wall on the right . Going slowly with outgoing current diver can notice lots of large marbled groupers, purple queen anthias, nudibranchs and one spot and humpback snapper. Where other side has 2 complete turtle skeletons inside the cave that are the only attraction. This true cave should not be entered unless all divers have proper cave diving training and equipment. 

   German Channel   

German Channel takes its name from a man-made channel cut out of an inner reef within an inner lagoon, but diving actually is the best at the outer portion of the reef area near the channel. The best time to dive a the site is during an incoming slack tide when Manta Rays may be feeding or being cleaned at a couple of a cleaning stations. Divers descend to about 20m/65ft and swim crosscurrent along the sandy bottom. 

Feathertail stingrays and thorny rays may be seen. Whitetip and grey reef sharks may be either cruising or being cleaned at the stations. Microscopic organisms call plankton funnel into the channel, and are a food source that manta rays regularly feed upon - especially late in the day on an incoming tide. After watching mantas or sharks or exploring coral heads, divers drift into the shallow part of the channel where leopard sharks sleep and turtles feed. There are certain times of the year when the manta rays are more common but resident rays are seen year around. Black Tail Snappers, form large aggregations each year in the channel. 

  Sias Wall /  Tunnel  

Just east of Siaes corner, is a straight swim down a vertical wall to the entrance of a large tunnel. The tunnel is a like a giant worm hole with three holes. Usually little current is present inside the tunnel through it may pick up once the diver exits. Plenty of natural light filter inside the tunnel though a flashlight is recommended to sea soft corals, cup corals small fish and inverts on walls and ceiling. There are many sea fans and black coral in the window and exit of the tunnel where they can filter palnkton out of the current. 

The tunnel is rather wide, about 15 meters across, with a sandy/rubble bottom sloping up from the entrance to exit. On the bottom, one can find various species of dartfish, gobies, frogfish and nudibrances. The top of the tunnel has lionfish, Conlin's angelfish, and burgess butterfly fish; many of which can be seen at no other dive sites. Aggregations of the orange spine Naso Lituratus (erangel) and the Morrish idol are observed during January through April before the half moon. 

   Big Drop Off   

This is one of the most famous wall dives in Palau. Done on either incoming or outgoing tide, usually a mellow drift dive along a vertical wall covered in many soft corals and sea fans, sponges, anemones, and small reef fishes. Quite often turtles are seen feeding along the wall. Purple headed filefish, longnone hawkfish, and school of surgeonfish, parrofish, angelfish, and butterflyfish are common. Even safety stops are exciting here, for the reef is teeming with sea fans, anemones, spotfin and cleanfin lionfish, and moray eels. On top of the plateau, in rather shallow water, many new coral are growing and this may be one of the healthiest looking shallow reefs on the barrier reef. Visibility usually ranges from 18 to 50 meters.

   Turtle Cove   

This dive begins by dropping into a small blue hole on top of the shallow reef flat. Wall of the hole have small soft coral, hydroids, and sponges. Drifting with wall on your right towards the corner, usually takes 20 minutes. There are large school of fairy basslets and small reef fish. Close to the corner there are school of Thompson's surgeon fishes. pyramid butterflyfish, and redtooth triggerfish, Along the wall, a large school of black snapper may congregate within close view of the divers. A handful of grey reef and whitetip sharks around the corner, with school of big eye trevally. Giant trevally cruise up in shallow water. Near the end of the dive, divers ascend to a plateau, which is like a giant aquarium. Diver can expect to see beautifal anemones, small reef fish, turtles, and sometimes a blacktip reef shark. Visibility is usually good, ranging from 10-13 meters. 


  Peleliu Corner  

The southern reef in Peleliu extends far outward from the island,, and eventually slopes to a sharp corner. On the western side of the plateau, there is a reef cut at a depth of 15m. At this site, high currents hit the wall and go up and over the edge onto the plateau.

Sharks aggregate at the cut surfing the currents along with king mackerel, yellowfin surgeonfish, and redtooch triggerfish. Hammerhead Sharks, Tiger Sharks, Sperm Whale was also spotted here. It is the rather strong current that brings all these predators to this area. At the start of the dive, divers generally drift along Peleliu wall for a short distance, and then use the reef hook at the cut to watch the action. After unhooking, divers usually drift into the shallow part of plateau, also known as the Peleliu Aquarium. Peleliu cut and corner are actually two different dive sites, but can be done with more experienced divers who wants to see some bigger actions and do not mind diving while swimming against and fighting the rather fierce currents that are present here. Visibility is usually excellent, ranging form 20-40 meters.  


   Chandelier Cave  

This is a cave dive that does not require divers to be equipped with too much skill or tools. One flash light and one dive guides and divers enjoy the creativeness of nature cave. There are 5 separate chambers inside the cave where divers can come up to the air pocket and obverse different shapes of stalactites. As the stalagmites are continue to grow over the years, divers will see the glitters once shine the flashlight on it like its name Chandelier. As the cave contains zero light, it barely has any coral nor organisms. Dives could find cardinal fish, soldier fish inside the cave, and occasionally mandarin fish, shrimps and crab outside the cave entrance. 

The deepest part of the cave is 15 meters, divers who are concern diving in darkness please be advised by dive guides or cancel. 

  Jake's Sea Plane  

A seaplane that is 11m/37ft long and lies at the depth of15m/50ft on the west side of KB bridge. Most part of the sea plane remains intact

   Iro Maru   

A 140m/470ft long Japanese navy fleet oiler that was destroyed in 1944 by a U.S.submarine torpedo. sit's positioned as follows: bow in 20m/65ft, stern in 25m/85ft, fowrard mast up to 10m/35ft, and bottom at 40m/130ft.
