Ulong Channel
Ulong Channel: Palau's signature drift canyon
Western Ulong Island channel with a shallow coral-lined bottom, reef hooks at the mouth, and fast tide-driven drift diving.
About Ulong Channel
Ulong Channel is a current-driven canyon on the western side of Ulong Island, where a shallow sandy bottom, coral heads, and lettuce-coral forests turn the dive into a fast drift through one of Palau's signature sites. Advanced divers hook in at the mouth, watch sharks and schools of fish work the flow, then drift as the current changes. The site rewards adaptable teams with groupers, triggerfish, clownfish, batfish, snappers, and other reef life.
