Hon Ko
Hon Ko is the destination to visit in Vietnam if you want to observe coral reefs. The mostly uninhabited island may be reached in 10 minutes by boat from Nhon Hai Commune in Binh Dinh's center province. It's all about the sand, the cliffs, and the coral reefs. The corals are relatively near to the coast, with only one to two meters of sea depth. Simply put on your goggles and submerge your face in the water.
This area, also known as 'Dry Island,' is worth scuba diving in Vietnam for its spectacular underwater coral reef system. The few rocks protruding from the sea may not appear to be much on the surface, but beneath the surface is a spectacular reef system home to mitre shells, rays, bamboo sharks, nudibranchs, catfish, and scorpionfish.
