Ulong Island is a main island and channel of the western part of Palau. Ulong is known among the divers as one of the best places for drift diving in the world thanks to strong tidal currents.
The best Ulong Island dive sites are the following:
Ulong Channel is located on the reef of the Ulong Bay. It is the third most popular dive spot in Palau and one of the best diving channels in this region. The descending starts at the mouth of the channel which length is about 1km/0.6mi and the average depth is 12m/39ft.
Siaes Corner Reef is located to the west of Palau at the north-west of Ulong Island. There are many amazing dive spots depending on the direction of the current. The dive site is good for both novices and experienced divers.
Siaes Tunnel is located at the southern shore of Ulong Island. Divers start to descend near the vertical wall and then go along it reaching a huge hole in the reef stone. It leads to a long tunnel that is 15m/49ft in diameter and 50m/164ft long.
Shark City is the reef in the form of a finger that is the most western point of Palau. It consists of several fascinating dive spots. Shark City is formed with vertical walls with moderate slopes and canyons. The reef starts at 17m/56ft and ends at 50m/164ft depth. This place is recommended for the divers with advanced or higher level. Currents along the reef can be very strong and unpredictable. The availability of the buoy is recommended.
