Elephant Head Rock
Visible from the surface, Elephant Head Rock is the biggest pinnacle in the Similan Islands and north of Deep Six and south of Beacon Reef. It is located 1.5 km to the south of Koh Similan Islands. There are three large boulders that emerge above water, with the biggest located to the west.
Divers have often seen whitetip reef sharks and blacktip reef sharks outside the boulders. In addition, juvenile whitetip reef sharks can sometimes be seen lying in the cracks of the boulders. In mid-water, schools of fish including blue fin trevallie, fusiliers and rainbow runners are common. Near the exposed boulders, giant trevallie and great barracuda are a common sight. Also, divers may encounter large snappers and sweetlips in cracks, holes and swim-throughs.
Pairs of purple fire gobies can be found in deeper areas, and rockmover wrasse, clown anemone fish, and blennies near the rocks. Boxer shrimp, cleaner shrimp and octopuses can be found inside some cracks of the boulders. Lastly manta rays and whale sharks have been reported here too.
This tin dredger wreck lies not very deep, and is not too large to explore overall. However, it’s quite difficult to look into every detail, so try to explore at a slow pace. You can start the dive at the outer sand area and come back to the wreck, but make sure to explore around before going up to the top. Close to the sand bottom, avoid stirring up the sand, as this will lead to unclear visibility. There are plenty of scorpion fish and lionfish camouflaged on the sand and on the wreck. Therefore, it is best not to touch any part of the wreck. The wreck has been there for a long time, so do not risk harm to yourself by trying to enter the structure. The vertical wall on the west side of Elephant Head Rock falls on the deep and sometimes has down welling.
Thus diving on this side should be avoided. Strong currents can produce unpredictable surges close to the rocks and swim-throughs. Divers may hit and damage corals or even injure themselves. Thus, this site is recommended foe experienced divers only. Furthermore, you should enter a swim-through in single file, in order to avoid entanglement and avoid accidental damage to corals.
