This dive site, Koh Hey (also known as Coral Bay), is a sheltered bay featuring a small wreck at 8 meters depth. The dive typically begins in the bay, which slopes gently deeper towards a sandy bottom. There is no specific historical information provided for the wreck, but it serves as an interesting focal point for divers.
The site is rich in marine life, boasting nice coral formations that host numerous small reef fish. Divers may also be fortunate enough to encounter large schools of vibrant yellow snappers, adding a dynamic element to the underwater scenery.
The best time to visit Koh Hey/Coral Bay for optimal visibility is on "good days" when it can exceed 20 meters, though it can sometimes drop to 3-5 meters. It is highly suitable for snorkelers due to its shallow depths and abundant marine life. For divers seeking more adventure, an optional drift dive to the south offers deeper exploration up to 40 meters.
