This dive site is very similar to other dive sites in the Similan area and offers divers a chance to see a large submerged pinnacle that goes down to a depth of around 22 meters. The dive site has several different names and can sometimes be referred to as Ko Pachumba, Ko Pratumba, or Ko Glang. The maximum depth here is around 30 meters and as it is found within the Surin Islands National Park divers can expect good coral and an abundance of marine life. The currents here can vary and so divers need to plan their dive accordingly. As there are many dive sites in the area, it is not uncommon for divers to dive this site as part of many other spots in one day.

The pinnacle is covered in many corals both soft and hard, and so has much marine life living in and around the area. Divers can easily spot fusiliers, snappers, batfish, and wrasse. There will also be many shrimps, crabs, and lobsters hiding within the surface of the pinnacle. There is also a great chance of spotting some of the turtles in the region and some of the reef sharks. The parrotfish here are also very large and make for great photo opportunities.
