Level of Diving Experience: Advanced.
Diving Depth Summary: Top of the Reef to the Bottom: 10 to 40 feet (3 to 13 meters).
Currents: The currents at Ulong Channel can be strong and unpredictable. It's not uncommon to have the direction of the current change abruptly halfway through the dive. If this is the case, simply turn around and drift in the opposite direction.

General Information: This channel is sometimes referred to as Ngerumekaol Pass. Due to the close proximity of Ulong Island it is commonly known as Ulong Channel. Ulong Island is a great place for aPhoto by Peter Lange picnic because of its beautiful beaches and its historical significance. Ancient Palauans painted a series of petroglyphs on the high cliffs of the island. Be sure to have your Dive Guide point out the petroglyphs as you pass the western side of Ulong Island.

Reef Formation: Ulong Channel runs west to east and cuts only partially through the western barrier reef. The barrier reef runs perpendicular to the channel. The sandy bottom of the channel is 10 to 40 feet (3 to 13 meters) deep and is decorated with numerous coral heads and coral formations. The sides of the channel start just below the surface and gradually slope toward the sandy bottom.

Marine life: Gray Reef Sharks, sting rays, schools of jacks, snappers, barracuda, and batfish are frequently seen at the entrance. When the moon is full, during the months of April, May, June and July, thousands of groupers gather here to spawn. Groupers are usually a solitary fish, but during this time they have been seen to school. Titan Triggerfish also use this area to nest. When Titan Triggerfish are nesting they become extremely territorial and protective of their nest sites. Titan Triggerfish will dig out large depressions in the sandy bottom to lay their eggs. To avoid being attacked and bitten by jealous triggerfish, divers should keep their distance.

Diving: The dive usually starts along the reef at the northern side of the channel by dropping down to 60 feet (20 m). Keep the reef on your left side. About 10 minutes into the dive you will approach a sandy run-off, this is the entrance tothe channel. Grey Reef and White Tip Sharks are always on patrol here and the current is usually strong. Hook on to one of the rocks and watch the action. Once you leave this area be prepared for one of the most exciting drift dives in Palau. Let the current carry you into the channel. One of the most impressive sights the diver will see is an enormous section of lettuce coral that has grown from the bottom of the channel to a height of 15-20 feet (5 to 7 m). The eastern end of the channel is deeper and the bottom is mostly sand.

Deutsche Beschreibung:
Sich diesen Naturkanal entlang treiben lassen erinnert an eine Kutschfahrt über eine schneebedeckte Einkaufsstraße im Winter. Der sandige Kanal ist die schneebedeckte Straße und auf jeder Seite pulsiert das Riff vor Lebewesen, die hier in geschäftiger Heiterkeit herumwimmeln, während die Korallen die blinkenden Dekoration bilden.
