Koh Ha or Island #5 is a tiny island gem. Yet, visitors can expect a terrific experience as it is one of the most popular locations for diving in the Similans. Koh Ha is surrounded by a vibrant coral reef offering visibility of up to 50 meters to view an abundance of marine life.
The main attraction that one can see when traveling to the island would be the garden eels. Garden eels are common while diving on Similan Islands, but in particular on Koh Ha. These white and grey creatures are often seen stretching out their necks from the holes on the sandy floor, making them look quite amusing. By pretending to be a colony of sprouts growing on the seabed, garden eels feed on zooplankton that currents deliver to them. An interesting fact of this creature is that it gets its name mainly from its practice of poking its head from the burrows like plants sprouting from the ground in a garden.
Anita’s Reef is a popular site which is located to the east of Koh Ha, offering a pleasant reef diving. It is also not far from the famous Hideaway Bay. Those who are ready to dive deeper will find a series of statues at the bottom of Hideaway Bay, which includes the figures of mermaid placed in a sweeping arc. The main attraction at Anita’s Reef would be the bommies or coral heads. Divers can keep a lookout for shoals of glassfish and the occasional appearance of marine reptiles at this dive site. Other types of marine life include the blue-spotted stingray and another variety of the garden eel, the spotted garden eels. The Reef proves to be a relatively easy dive site with an extensive sandy area where divers can practice the sport.
