Peleliu
The island of Peleliu, at the southern tip of the main archipelago of Palau, is bordered by magnificent walls. The dive sites include Peleliu Corner, Yellow Wall, and Orange Beach, among others. Peleliu dive sites are mainly steep walls covered with sea fans, sea whips, hard corals and anemones, but dominated by soft corals. Peleliu is an excellent place to observe large pelagic life, particularly sharks.
Short Drop-Off
A sloping wall just outside the entrance to Koror Harbor that is covered with giant seafans. The top of the wall is a beautiful coral garden loaded with tropical fish and invertebrates.
Siaes Tunnel
An extraordinary deep dive on the west side of the Palau, close to the Ulong Channel. The dive begins on a sheer wall with the opening of the tunnel starting at 70′. You enter through an opening, which is about 50′ across and 20′ high, and swim through the tunnel, which parallels the wall for 150′. The inside of the tunnel is a large cavern with a ceiling at 80-90′ and the floor at 120-130′. Halfway through the tunnel is a “Window” in the wall that looks out onto the deep blue. You exit through a large opening on the wall at 80′. Stingrays, turtles, schools of jacks, and sharks can be seen in and around the tunnel.
Ulong Channel
This channel is located on the west side of Palau, close to Siaes Tunnel and Wall. Its entrance is surrounded by walls that are topped by beautiful coral gardens. On the incoming tide, the mouth of the channel is filled with gray reef sharks. The channel extends for a distance of approximately one-half mile, averaging 100′ in width. The maximum depth is about 60′. Coral covered walls run the length of the channel on either side. A shallow ridge running the center of the channel is blanketed with soft corals, hard corals, sea fans, and anemones. Unique to this site is a huge patch of plate coral resembling lettuce leaves that is home to schools of squirrelfish, soldierfish and glasseyes. The current provides a gentle push, resulting in a beautiful, leisurely ride along the channel.
Wonder Channel
Located within the rock islands just a short distance from Jellyfish Lake and Clam City, this channel is best dived on the east side along a wall that starts at the surface and reaches a depth of 80′. Soft corals, sea fans, anemones, blue and red starfish, crown of thorns star-fish, crabs, pipefish, and a large variety of sea slugs, flat worms and nudibranchs can be found along this wall.
Wreck of the Iro Maru
A 145′ long merchant ship sunk during World War II by American bombers, the Iro Maru sits upright in 120′ of water just 10 minutes south of Koror. Three mast and gun turrets at the bow and stern support a large variety of invertebrates and hard corals. The main deck is at a depth of 80’with open holds containing oil drums and machinery.
