Ulong Channel

Ngerumekaol Pass is another name for this channel. It is known as Ulong Channel because of its close proximity to Ulong Island. Because of its beautiful beaches and historical significance, Ulong Island is a great place for a picnic. On the island's high cliffs, ancient Palauans carved a series of petroglyphs. The Ulong Channel is regarded as one of the world's best drift dive sites. The entrance to the Ulong Channel is full of beautiful coral formations, and once the tide comes in, you can see the many sharks feasting on the fish that had been stranded in the channel after the tide had gone out.

The currents at Ulong Channel can be unpredictable, and have been known to change dramatically mid-dive. This dive site is only recommended for advanced divers. Stay close to your guide, as you may need to change direction. The best time to dive the Ulong Channel is during an incoming tide, when the current is strongest and visibility is clearest, stretching for more than 30 meters. As you pass by the western side of Ulong Island, make sure your Dive Guide points out the petroglyphs.
