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.

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.
