Why German Channel is one of to the top three dive sites in Palau and one of the world’s best manta dives

As already mentioned in an earlier post, the three dive sites which are a must for every diver visiting Palau are Blue Corner Palau, Ulong Channel Palau and of course German Channel Palau.

My last dive at German Channel was from our liveaboard the Ocean Hunter Palau - but of course we also offer this great dive with our land based hotel-dive packages

I enjoyed this dive tremendously - I’ve been to the Maldives and 9 years in Yap and have seen my fair share of mantas - but German Channel tops it all.

The way we did the dive was to first have a look at two cleaning stations and we didn’t have to wait long - two mantas and some grey reef sharks were at the station getting serviced by small cleaner wrasses. Mantas in slow motion - hovering on top of the service station taking off and returning in a circular motion after flying slowly over our heads posing for our guests to get close up photos and videos.

From the cleaning station Kenneth took us along the reef, which is amazing by itself - lots of fish, sharks and lovely sea fans - further into and finally mid channel, where we witnessed the most amazing manta action ever. Lots of mantas, feeding, looping, making the train - manta diving at its very best.

One of our guests Sigala has made this amazing video attached to this blog - it’s supposed to give you an idea on how German Channel can be :-)

To give you more insight to German Channel we’d like to share the following great dive site description with you - it’s an excerpt of the book “Palau Diving & Snorkeling Guide”, written by Fish ’n Fins directors Navot & Tova Bornovski and available at Fish ’n Fins Boutique or at Trade Shows if you are fast enough to get one.

German Channel Palau Reef Map


Incoming tide: 60 to 120 feet (20 to 40meters). Outgoing tide: 60 to 30 feet (20 to 10 meters).

Level of Diving Experience

Novice to Advanced.

Diving Depth Summary

Cleaning station: 55 to 60 feet (18 to 20 meters). Channel Entrance: 10 to 30 feet (3 to 10 meters). Slopes: 15 to 120 feet (5 to 40 meters).


Incoming tide: the current will flow from the open ocean into the lagoon. Outgoing tide: the current will carry murky debris laden water from the lagoon to the open ocean. For more information regarding the tidal patterns in Palau, refer to the Blue Corner tide and current section.

General Information

German Channel is the only channel in the area to funnel the outgoing and incoming tides from the inner lagoon. The result can be very strong currents through the mouth of the channel and in the channel itself. Due to fast moving water, a shallow bottom and speeding boat traffic the channel itself does not offer any diving. The southwest mouth of the channel is known as the German Channel Dive Site.

Reef Formation

German Channel runs from Northeast to Southwest. The cut through the western barrier reef between Ngemelis Island and the shallow reef that stretches north of Ngercheu Island (Carp Island) was done during the German occupation (1899 to 1914) of the islands . The channel connects the inner lagoon with the open ocean. The open ocean floor, between the two islands, rises sharply from 1000' (330 m) to 120 feet (40 m) and than gradually to 30 feet (10 meters). The northern and eastern slopes that border the diving areas are covered with large variety of hard corals. The mouth of the channel has a sandy bottom spotted with numerous coral heads and coral formations.

Marine life

German channel is known for Manta Rays, schooling sharks and an abundance of tropical fish. Almost every form of marine life can be seen here. Thousands of jacks will school here along with barracudas, trevaly and snappers of numerous species. The sandy bottom is home to garden eels, blind Gobies and Mantis shrimps, to name but a few. During the incoming tide Manta Rays can often be seen inside the shallow channel. In the late afternoon, the Manta's can usually be found feeding on plankton and krill at the mouth of the channel. Reef sharks are also known to come to the cleaning station at the mouth of the channel. It is the lucky diver that gets to see a shark standing vertically with its head thrown back while cleaner wrasse and butterfly fish hurry to clean its body. Sighting cuttlefish is another reward for the observant diver. Important Note: Mantas will approach a cleaning station a couple of times before they hover over the station. At this time the cleaner wrasses and the butterfly fish do their job. If divers chase the Mantas, the Mantas will leave and not come back!!! Be very patient, let them come and go; eventually you will get the photo opportunity of your life. Remember, patience is the name of this game. Keep a distance from the station and let them come to you. The rewards are worth the wait.


Two moorings mark the north and south border of the diving area. Your dive guide will decide where to start the dive according to the current, weather conditions and other boats in the vicinity. The dive usually starts from the southern buoy. On descent you will see the shallow reef to one side and a steep slope on the other side. Follow the slope down about 50 feet (17 meters), keeping the reef to your right. Soon the slope will turn into a very wide sandy plateau. At 60 feet (20 meters) there is a cluster of large rocks. This is a cleaning station. Swim 15-20 feet away toward the shallows and wait for the Mantas or sharks. While waiting, look around, if you see large craters in the sand or between small rocks, you could be in a nesting area of the Triton Triggerfish. Triton triggerfish are probably the most aggressive fish in theocean.

When nesting Triton will attack any fish or scuba diver that unknowingly enters the nesting area. Looking down at the sand you can also see blind shrimp lodging together with the Brown Gobi. Watch carefully and you will see how these two (2) fish work together for mutual benefit. Upon leaving the area swim to the coral heads and follow them along the sandy bottom. At this point, you will start to sense the German Channel experience as you are surrounded by schools of fish and patrolling sharks. A wonderful sight!!!!! Continue along the bottom at 30 to 40 feet (10 to 13 meters) until you reach the slope on the other side (northern buoy). If the current is strong do not fight it; let it carry you toward the lagoon. You will, literally, fly over patches of lettuce corals and Giant Tridacna Clams. Before you surface, listen carefully for the sound of approaching boats. Use a safety sausage to alert boat drivers to your location in the water. Night Diving: German channel is one of the best areas for night diving. Both moorings offer excellent vantage points to see night critters. CAUTION: German Channel is a major passage to the southern dive sites. Dozens of speeding boats cross this narrow pass daily. Be extremely cautious while ascending to the surface, always mark your spot with a safety sausage during safety stop.

Fascinating Facts

During the German occupation of Palau, guano (phosphate) was mined on the southern island of Angaur. In order to bring the guano to town, for trans-shipment to Europe, a channel had to be excavated. The Germans blasted and dredged a channel through the barrier reef between Ngemelis and Ngercheu. Today only speedboats and shallow draft vessels can transit the shallow channel.
