HON TAI SOUTH

Hon Tai South is the complementary dive site to Hon Tai North on the southern face of Hon Tai island in the Cu Lao Cham Marine Reserve — a UNESCO World Biosphere Reserve off Hoi An on Vietnam's central coast. The southern aspect of this Cham Island creates a markedly different diving character than the exposed northern face: the south-facing shore tends to be more sheltered from the northeast monsoon swells that affect the northern sites, and the underwater topography features different current patterns and reef exposures that support a somewhat different species assemblage. Both Hon Tai sites are rated advanced due to the open-sea character of the Cham Islands diving and the depth and current potential of the reef, which requires divers comfortable with drift diving technique and deeper water management. The coral community on the southern face reflects the sheltered character of the site: denser coral coverage in the shallower zones, with diverse branching Acropora formations and the table corals that thrive where current-driven damage is less prevalent. Fish communities at Hon Tai South benefit from the shelter: larger resident grouper populations claim structural features on the less-current-swept southern reef, and the rich invertebrate community — cleaner shrimp, feather stars, and the diverse nudibranch fauna of the central Vietnamese coast — colonizes the encrusted rock surfaces in impressive density. Whitetip reef sharks rest on sandy patches at depth. Spotted eagle rays glide through the deeper sections. The journey to the Cham Islands from Hoi An — passing the ancient town's UNESCO World Heritage waterfront and heading out to sea — adds a cultural and experiential richness to these diving excursions that is unique in Vietnamese dive tourism.
