Koh Racha Noi
Racha Noi, another 45 minutes South of Koh Racha Yai, offers some truly spectacular dive sites with giant underwater boulders, great visibility and scenery almost like the Similan Islands. Currents here can be strong, and some of the dives are recommended for advanced divers only. There is deep water around the island, so you often see large pelagic visitors such as barracudas, eagle rays, marbled stingrays and there is a chance of encounters with manta rays. But there are also shallow areas and sheltered bays, so the island is suitable for all levels of diver.
There are several dive sites here. Banana Bay is probably the most dived because it has a shallow bay with depths from 3 – 10 meters, making it great for first time divers. Outside the bay a gently sloping reef reaches about 25 meters depth. You may find schools of snappers, small barracudas, moray eels, triggerfish, butterfly and bannerfish. This site is on the east coast and mostly dived in our “low season” when prevailing winds are from the west.
