Liveaboard Diving in German Channel

What to expect on a German Channel liveaboard

Liveaboard diving to the German channel gives divers the chance to get up close with Manta Rays. The German Channel is sometimes said to be a natural occurrence, but this is not the case. This channel was created by the Germans in the early 1900s as they were mining guano (phosphate) in Micronesia and needed to transport it out of the lagoon into the ocean, which this channel then allowed them to do. It is located in the Rock Islands in Palau, East of Ngemelis Island, and 37 km (23 mi) from Koror, so about 40 to 50 minutes by boat. The channel itself has extremely strong currents and a lot of boats which pass over it, so divers cannot go there, the dive site is located on the southwest mouth of the channel. Even though the visibility on average is very good, it depends completely on the tide. When it is incoming tide the visibility is best because lots of clear water is brought in, it is between 20m (60ft) to 40m (120ft) and with the outgoing tide which brings a lot of plankton and algae with it, the visibility is about 10m (30ft) to 20m (60ft). Liveaboard diving at the German Channel is suitable for all levels of diver, the overall area slopes from 5m (15ft) down to 40m (120ft).

What You Can See

The most popular attraction for liveaboards at the German Channel dive site is by far the Manta Rays. This is one of the best dive sites in the world to see and come close to Manta Rays which can have a wingspan up to 3m (10ft). They are very shy creatures, but here they do come quite close to the divers, however, the trick is to be patient and never chase them, as then they will not return. They will come and feed on plankton there at their feeding station but one of the best things you can see is the manta rays vising the cleaning stations. Here they will sit with mouths open and gills open to let the cleaner wrasses and butterflyfish clean everything, and absolutely great photo or video opportunity. Apart from the famous Manta Rays, this dive site has a lot more underwater life to offer including schools of blacktip reef sharks and grey reef sharks, barracuda, trevally, snappers, and many more tropical fish.

Getting To German Channel

To get to this dive site, or to get to any Micronesia liveaboards which will be visiting this area, then you will need to make your way to Koror, which is the largest city in Palau. The airport is located on the island of Babeldaob which is connected by a bridge to Koror . The airport is called The Roman Tmetuchl International Airport. There are only five destinations that have outgoing flights to Palau, so you would have to fly to one of these first; Philippines, Taiwan, South Korea, Japan, and Guam. Once in Palau, everything is organized mostly from Koror, and any German Channel liveaboards will depart from the Malikal Harbour in Koror. It has been said that the best months to go are from December to June, however, it is always possible to dive here.

The first time we went, visibility was awful, but the second time visibility was good, and we were able to see some cool stuff. The dive site was a little overcrowded, which scared off the one manta ray that actually did show up.

The manta migration has changed since last year when circling mantas - one after the other appeared. Yes, there are Mantas - but not in the numbers. There are also other pelagics that frequent the channel but you want an incoming current to ensure 100% adrenaline with your nitrox!
