Conditions & tides

Channel site — tidal current funnels through here and can run fast, changing quickly with the tide. It is usually strongest around mid-tide and eases near the slack windows below. Dive with a local operator who knows the timing.

About this site

Ngedebus Wall is the west wall of Ngedebus Island in Palau, southwest of Turtle Cove. It is a corner drift dive along a cliff-like wall that stays on your left at 20 to 30 m, past colourful soft corals and giant sea fans, ending on a shallow plateau at the corner at 5 to 8 m, where divers hook in. Visibility is 17 to 50 m and over, and the current is moderate to strong. It is rated for Advanced Open Water divers, and a reef hook and nitrox are recommended.

At the corner, sharks, barracuda, snappers, humphead wrasse and eagle rays put on a show. Unexploded ordnance from the Second World War is still occasionally seen in the area and must not be touched.
