The little island Koh Ma

Koh Ma is a small rocky island located on the west side of Koh Phangan, at the end of Mae Haad beach. Most of the island is rocky with near vertical cliffs. Only one section is accessible by land. A sand bar forms at every low tide connecting it to the main island. People will often visit the section where there is an abandonned resort.

Underwater Koh Ma is arguably the best dive site around Koh Phangan. Ranging from 5 meters to 22 meters, it have big corals and rocks where creatures and fish can hide. There is also very big barrel sponges scattered around. Schools of chevron barracudas and yellowback fusiliers swims around while there are other reef fish swimming through the coral.
