German Channel

If you ask an experienced diver about diving with manta rays, German Channel will undoubtedly come up. Because the German Channel is endowed with a few Manta Ray cleaning stations, here is the site where you will be able to witness these huge rays every day.

These cleaning stations are located on the reef's slopes, surrounded by a sandy bottom at a depth of 30 to 40 feet. Cleaner fish eliminate parasites from the rays' skin when mantas and sharks glide over these slopes, find a free station, and hover in place. German engineers in Palau blew a hole in the atoll and excavated a canal between the inner lagoon and the outer sea over a century ago.

They accomplished this to lessen the risk and time involved in transporting phosphate from the mines to the port, where it would be sent to Europe. Today, the incoming tides send powerful currents into the lagoon, and these currents carry nutrient-rich waters from the depths, which the rays take advantage of by stationing themselves near the channel's entrance.
